The dancing was based on the games Ticker. This quick update--- updates from the games current playing note index. This keeps his dancing at a more fixed speed (in tempo to the music) Now with a file actually attached:- -------------------------------------------------------- Addendum a couple of hours is a long time:- jsw VL5 DEMO revision3.tap The animation is based on the tempo of the music, and is too Manic (right frame of mind but wrong game). I could slow it down to look less Manic. (Tried it and was still not happy.) jsw VL5 DEMO revision3a.tap The animation in this version is based instead on the note being played. So if a note is sustained, the animation will not change. The sequencing of the animation is solely dependent on the value of the note played. So the animation is fixed by the music. I feel this whilst erratic frantic (not Manic) better suits the game. Alas I am out of memory so the next addition I did corrupted a pile of data. Some visual screen data is deliberately placed at the end of available space, and if I exceed my code space. The data will be displayed on the screen as a mess. this indicates visually to me the limits of editing. Whilst I had to delete this routine the idea was to actually play the wording of the tune across the bottom of the screen as Willy danced -- Looked interesting, just not interesting enough to accommodate into the space available. Something would need to be deleted and the routine was not exciting enough to progress any further.

The way this plays music bears little resemblance to the way Matthew played music. His was just an incremented pointer, playing at a fixed rate. Code wise :- 35648 LD A,(34273) Increment the in-game music note index at 34273 35651 INC A 35652 LD (34273),A 35655 AND 126 Point HL at the appropriate entry in the tune data table at 34399 35657 RRCA 35658 LD E,A 35659 LD D,0 35661 LD HL,34399 35664 ADD HL,DE at this point (hl) holds the note data "BC" will be set with a fixed value of 3 and my code --- minus most of the comments and data ; this plays variable length and variable note repeat and even mutes the music if needed the call to STEP_INDEX- this adds "A" to "HL" and returns the contents of "(HL)" : A=(A+HL) The routine below plays the in game music, changed from just being a variable delay. snail_run: ld hl,var_flag ; this is the speed factor LD a,(MUSIC) ; the music flag (on/off) bit 1,a ld a,(hl) LD D,0 jr Nz,set1_version add a,4 LD D,#18 set1_version: or a ret z ; this loop is repeated less than 20 times at maximum slow down ;(the speed to execute this code compared to the delay this is calculating, means it is insignificant) ; on a flat out game (music off and fastest speed) this code is not executed. ld e,a ld bc,$190 ; a delay value ld hl,0 sgk: add hl,bc dec a jr nz,sgk ld c,l ld b,h ld hl,repeating_note ; table of Blip values (how many times the note will blip) ld a,e call STEP_INDEX LD E,A S_M_C_RECHARGE: EQU $+1 ld a,2 dec a jr nz,se1_note inc (hl) ld a,E se1_note: ld (S_M_C_RECHARGE),a ld a,(hl) and 63 LD HL,Music_data ; table of note data CALL STEP_INDEX ld e,a E= note BC= duration L= mic toggle D=mic toggle (the routine uses "L", so this must be copied, somewhere) Note standard in all my code. if something starts with S_M_C_ it is indicating the value or variable is part of inline code that will be modified e.g. Self Modifying Code ;-------------------------------------------- The game notes are still played as designated minimum of two blips per note, However on the first pass the blip count is set to two and is similar to the problem in the original JSW. This is decremented and the first blip is played. This is one blip before the note index is moved to the next note. On first game start up the speed index is set to very fast and in this instance the number of blips is set to 5 for all the subsequent notes and the blip counter should be set at 5 (or even 6) . Not as stated above at 2. Playing one blip is equivalent at the game start to playing 1/5 of a note, Which is more noticeable than the equivalent problem in the original. All the changes in speed reset the blip count after each note. The routine has no external counters and does not get updated outside of the music/delay routine. The note index is reset on each game. The technical problem is the blip count, which was not reset and due historically to this being a two blip game was left as 2 (which would have still omitted the first half of the note, even if the game was started at the slowest speed). I thought it would take too much code to actually adjust the blip counter at reset to the required value on a game reset (I knew it was a problem- just was not bothered, to actually fix it--- this does have a great big banner on it saying DEMO of speed) addendum to the paragraph above......( on subsequent slow speed game, playing, with 2 blips per note) Not resetting the blip count can make it either skip one blip on subsequent game resets or skip the whole note. The chances are 50-50 I have now fixed this problem and inserted a blip reset, and changed the note index to the last note. This ensures on the first pass the blip count is reset to the correct value for its speed, and the note is stepped to the next note, which will be the first note. This was done by changing the data in a data reset list from (NOTE_INDEX ,0) to (NOTE_INDEX ,63) and inserting 2 more values (S_M_C_RECHARGE , 1). The modification was far easier than I thought at the time of writing the original. ------------------------- As I mentioned before I do not listen to the music, it is turned off. If the game had crashed or started playing very obvious long note sequences.I might have checked it a bit more or at least bothered to investigate how I could reset the data. It played and it was not the focus of what I was doing.

Noted the one note... Duly changed. I tend to not listen to the music. And I normally have no sound output on my PC. Others in the room do not appreciate the sound playing.

I have uploaded the Demo version of JSW 128 VL5.tap The slight name change is to JSW VL5 demo.tap. This is up loaded as a revision of JSW128 vl5.tap This demonstrates a very very very fast version of Jet set willy. This version also now plays music and not blips for the in game music. The tempo of the music is adjusted as the games speed is changed.. Since the basic music note is played twice, it was not possible to do step-less adjustment, for the faster versions. A large amount of extra graphics and routines added. All the graphics are displayed bit by bit in the extra title screens added. (over 21 variations on the title screen- based on the main five ) To see full speed, turn off the music. Since the option to upload is here (as well) I will attach the file here. ----------------------- One note changed. Typing error. The tune routine like most things was changed and speeded up. This meant all music data needed to go through a translation table to adjust its speed. The data had a misplaced digit. The note was only played once. ---------------------- I will attach the last version here (19th January 2019) JSW VL5 DEMO revision 3b.tap -------------------------------------------------- All the main screens. JSW VL5 DEMO revision3b.tap

Modification of Manic miner tune. The above routine was an exercise in compacting the code. Code that was never used. The original modification from. SUB 8 RRCA RRCA RRCA CPL OR #E0 TO RRCA RRCA RRCA NEG OR #E0 --- my code has OR L where L=#e0 This modification works fine and gives exactly the correct results. And does not need any additional code. my error was just swapping the routine around, whilst still thinking about the CPL instruction used in the first routine NEG RRCA RRCA RRCA OR #E0 --- my code has OR L where L=#e0 Moving the NEG from after the RRCA instructions to before the RRCA instruction changed what it did. Simpler to revert back to the sequence SUB 8 CPL RRCA RRCA RRCA AND 31 OR L Since the above code has been tested. I know it works for all values, in exactly the same way as the original. Works 100% The routine is still 70 plus bytes smaller than the original. Addendum. The AND 31 instruction was added before the code change to compacted data. The reason for its inclusion was to permit the moving of the piano graphics to any screen line, and not be forced via the old code to one of 3 fixed screen positions. 2nd addendum: The code I reference is the original layout. Unfortunately for me, I have edited so much code and done so many changes in the code, that I would need to keep going backward and forward checking items for reference. The code listed in the Manic Miner music routine, is a derivative of the original code, which because of dual usage no longer OR's in the screen address, It now adds it. This slight change is what the next post #12 is referring to as the difference in opcode usage. The code I listed is relocatable and not fixed to any memory address. In the context of being placed back into Manic Miner, it can again have the restrictions imposed on it. The tune data and the two data tables used for data expansion, can be fixed into a page, along with the fixed screen keyboard reference. This can remove several opcodes and make it even smaller. (something I will not do). I prefer the options of being able to have code where ever I place it

Compressed the data and the optimised the code routine size. I have since chopped another fives bytes of the routine, so around 62 bytes smaller. Going solely from your data of eight bytes. I assume a saving of around 70 bytes from the original.

The delay in response is simply caused by having no knowledge that comments had been placed here. The yellow target sprite. Signifies that objects collected in this room, will increase the rubber tipped darts catch that Willy fires at other sprites. I am pleased that the icon I drew managed to convey what is was.... A dart hitting a dart board. (at no stage is another sprite harmed by being hit by these very soft rubber capped darts. All that happens is they are instantly transported to a safe place. To await re-emergence in the room) The version VL5 is old . The version I have now is considerably faster, and has several improvements. The increase in speed is significant and I realised that rather than just slowing down the game when the slower modes are activated. It is just as easy to play the music. This means that rather than the background clicking of a note, in the slow game versions, I play actual notes (if music is turned off, it still uses the music routine, but sound output is disabled from the routine) I have also added a new set of title graphics and a lot of other changes. No room or game layout changes. The speed increase as stated is considerable, I am tempted to re-visit version VK and implement the changes to allow that to benefit from the change in logic. ( the amount of code change is vast - A couple of days work minimum, copying and changing routines from VL to VK. No plans to do in the near future ) ------------------------------------------------------------------------------------------------------------------------------------ The speed increase was caused by wondering if I could change the format of JSW so that it plays a full screen game. The bigger screen size would cause a possible 50% drop in speed. So I added some code to increase the game speed to compensate for a possible slow down. The previous statement does not indicate that the added code was actually a major change in how the game works. I was curious to see how much effort it would take to do this change and a demo version of Vl5 was written ----Expecting major problems ------ So I was pleased when I found that the basic idea worked, and it has subsequently been updated and improved. My speed standard , the double room walk, in this demo version can be done in 8.3 seconds. (the origin JSW takes 20 seconds) The tests conclude that a full screen game is an option. The problem for me is that the amount of change needed is, as always, considerable. Which is not really an option from the game data layout that I have at present. To implement a full screen game I would need to start back at the basic original code. To start again I would need to yet again construct an assembler listing that is relocatable. (*** note 1) For example taking Skoolkits listing, the source code generated is far from being a usable source listing for what I aim to do. There are far too many fixed page references, and offsets specific to the game. These all need changing and this in itself is a big job. This I do by manually editing the code, line by line reference by reference. If you saw my listings you would see the difference in layout. I let the computer/assembler do the calculations. The source code I generate from doing this is quite a lot different from what is seen in typical listings. Perhaps I should set my next task as being the output of a workable source code for JSW. ------------------------------------------------------------------------------------------------------------------------------------ Note 1. When constructing my version of the source code, I always succumb to temptation and edit the code as I edit the layout. This means I have never had an unmolested relocatable working source code. , . ! ,,, ...! .''...

My original edit of this from around six months ago is only 12 bytes shorter than the post #0 I admit I have had numerous attempts at shrinking the code, in most case the end result stayed about the same size. So those numerous attempts where deleted months ago. I did however try one more time to edit this routine, and I did save a few bytes. My final edit for the overall Manic Miner Music routine is around 57 bytes smaller than the Music routine from post #0 I did however try one more time to edit this routine, and I did save a few bytes. My final edit for the overall Manic Miner Music routine is around 57 bytes smaller than the overall Music routine from post #0 So you know it can be done. Addendum The music routine consists of two parts. The code to play the music and the music data. One without the other serve no purpose in the game.
-
If the zero's are changed to any other value you can move the illuminated note up to any position, as long as they both stay the same value, you will still have silence. Which does not change the fact that the keyboard illuminates. Since the design of the keyboard looks like it was constructed from several broken ones. Lets just assume that the far left key is not working, and when struck the keyboard makes no noise.
-
Very surprised it did not contain far more errors. I will edit but leave the errors obvious.
-
This is a re-use of the same algorithm. This time it translates a key press into a key value. Could be used for high score input which uses the keyboard to type in a name and not the easy scroll letters to get an input. The big wastage is the translate table. The purpose of typing this is only to show a quick re purposing of a routine. (Of note I have seen far worse than this) . . key_input: LD HL,TABLE-1 LD BC,#FEFE keyloop1: IN A,( C ) LD E,5 keyloop2: INC HL RRCA JR NC,key_pressed DEC E JR NZ,keyloop2 RLC B JR NC,keyloop1 JR C,keyloop1 << corrected JR key_input key_pressed: LD A,(HL) ;the key value from the keyboard . .

Changes are minimal. Only 4 bytes smaller I would be tempted to use "L" in place of "E", this leaves the register pair "DE" unused.
-
The method I use is different, and takes exactly the same number of bytes and T-states It is slightly different, but only because I prefer to have bits set for keys pressed, and the spectrum port read gives the bit reset for keys pressed. ;WAIT FOR ANY KEY press loop: XOR A #AF IN a,(#fE) #DB #FE CPL #2F AND #1F #E6 #1F JR Z,loop #28 #F8 ;WAIT FOR KEY RELEASE , Keyboard debounce loop: XOR A #AF IN A,(#FE) #DB #FE CPL #2F AND #1F #E6 #1F JR NZ,loop #20 #F8 Post #246 and post #247(this post) Both differ only in the condition at the end JR Z when waiting for a key and JR NZ when waiting for the key to be released I will stick with using the CPL instruction.
-
Sorry if my editing of post #243 seems to indicate that post #244 is reiterating the same issue. What actually happened, was I looked at what I had written and edited it. Went away and made a cup of tea, came back and posted the changes. Without seeing the response via post #244
-
The z80 mnemonic LDIR which stands for Load Increment and Repeat LDIR moves each byte in memory over a period of 21 clock cycles or 21 T-states Your code is slower and writes each byte in around 29 T-states LD HL, #5A60 LD B, #20 Loop: LD (HL), #46 ;10T INC HL ;6T DJNZ Loop ;13/8T 29 T-states compared to LDIR 21 T-states You can speed this up from 29 T-states to around 24 T-states. 1) use the "C" register to load HL, this saves 3T states 2) use INC L instead of INC HL, this saves 2 T-states. In the code indicated, HL does not cross a page boundary. But even this, is still slower than LDIR LD HL, #5A60 LD BC, #2046 Loop: LD (HL),C ;7T INC L ;4T DJNZ Loop ;13/8T 24 T-states compared to LDIR 21 T-states The timing T-states are ideal timings, writing to contended memory will slow this down. However on very short writes when B is small, the slowing of the loop compared to LDIR will be counteracted by not having to load several registers. The change in code does save memory, which is the purpose of the code change.

Leave the animation as 4 frames in both directions (as originally) I have edited the picture file to show the hand position in frame 2 Matthew drew the original in one colour, this edit whilst not exactly following what Matthew drew, will look correct. (I have not yet watched the video)- but I am in the process of going out, and will not be back at a computer till much later today.
-
Looks great, but I see problems in how you have animated Willy. The picture shows the four phases of Willy along the top (original) The middle row shows the four phases as far as I can tell from your version (These are poorly scaled screen grabs) The lower row is how I would correct the the animation. E.g. by editing the 2nd phase of animation. The problem that I see, is caused by Willies hands not seeming to cross over the side of willies body.

If you read the comment I made and compare it with skoolkid's comment they are not the same. The Skoolkid comment is that it draws the graphics twice. In the Final barrier it draws the top half of the playing screen three times. draw the top half of the room graphics ---------------- 1) 1st write to the top of the screen over writes with the Final barrier graphics-------- ------2) 2nd write to the top of the screen draws the lower half of the room Then writes the graphics for the final barrier again --------- 3) 3rd write to the top of the screen
-
Trivia concerning the code that places the final barrier on the screen. Manic Miner. Code from 35388 to 35514 The Final Barrier When this room is drawn, Matthew's code goes through an illogical sequence. Matthews room drawing LOGIC as written in the game. (1) Draw all the tiles for the top half of the playing area. (2) Check we are in the Final barrier and erase the drawn graphics with the final barrier graphics (3) Draw all the tiles for the bottom half of the playing area. (4) And again check for the Final Barrier, then erase again the top half of the screen with the Final Barrier Graphics. NOTE this writes graphics to the top part of the screen three times. (1), (2), (4) This should have been as follows Check for the Final Barrier and draw the graphics on the top half of the playing area. Skip drawing the tiles for the top half of the screen Draw the tiles for the bottom half of the screen.

I will chuck some figures around concerning the big chunk of data that is stored "the final barrier". When I was presented with that piece of data I wrote a simple piece of code and compressed it. The expansion code is small. The Final barrier data and the title screen data compressed into 170H bytes. The keyboard was stored separately, I think the keyboard compresses into 10 bytes. (the expansion code for the keyboard is not very big) It would be relatively easy to move the Final barrier graphics (compressed) , the boot, plinth and swordfish data into the unused source code space. The rest of that space could be used for code and un-compression routines. This then allows the room data to be compressed freely. Again it would be a simple task to write a routine to compress two sets of game data and place then into what is now the room data space. Yes a lot of work, but you end up with 40+ caverns, which would be two games merged. -------------------------------------------------------- Another reason I would not do this is not concerning the data, compression or data layout, it concerns how the game mechanics check for room numbers before altering how the cavern plays.
-
Curious to see the extent of room graphic data that is referenced by the game code, So I have done a quick scan through a listing. Not as many as I thought. These are the references to room specific data The Final Barrier Data Boot Graphic Data Plinth Graphic Data Swordfish Graphic Data (might be more, but not a significant amount of references)
-
Compressing caverns is very easy, however the game engine uses specific references to data within the room data. These references would all need changing JSW moves the room data into a specific area and the game engine then uses the fixed data positions. It would be possible to compress the data and modify the game engine to used fixed references (as per JSW) when playing a room, this permits the full usage of very aggressive compression on the room data. I would imagine 40+ rooms easily, (without looking at any data to quantify my statement) This is not something I plan on doing or want to do.
-
A long time has passed since the I wrote the above. I have been looking at ideas for a slightly different format, which would be inherently slower. So i investigated an idea and wrote the code to implement the idea. I eventually achieved a working game, and the code I tested and changed was from the above game. Worlds fastest was my claim at 10.61 seconds. The implementation of my idea in the game brings the above time down to. New game copy Method, 8.48 seconds. This is very, very, very fast: -------------------------- Whilst the method works on Jet Set Willy, I do not feel that it gives me enough scope to change the game into the format I had planned. Simply because speed was just one of the problems my new layout would present. The other is the amount of code that would need changing to implement the new layout. I had planned a big deviation in the basic screen shape, which ultimately modifies how every part of the game needs to handle the screen. Jsw is restricted by design to its present screen layout. The speed up code worked. Yet the multitude of changes needed to modify the screen are extensive, and in most of the cases that I have looked at the relevant code is not easy to change. -------------------------------------------- Double room walk down from 20 seconds to 8.48. with a lot of extra code. (but still 128 rooms and only 48k) .

JSW 128 VL5 View File JSW 128 VL5 This was written just after JSW 128 VK3. It is an extension of the game, which I pushed towards the feel of Manic Miner In this version changed over a period of two weeks, I took the idea of game save status and changed the way JET SET WILLY plays. If you can play JET SET WILLY then this version might actually be a hindrance to you. For the lesser player it adds the ability to keep on trying a sequence of the game until they master it. The only constraint to finishing is the time limit. There are no lives to be decimated, you are totally free to roam, and free to try any action. The catch is simply that for every instance that you would normally die and loose a life you transported back to the last portal that you visited. Infinite lives and lots of time, sounds easy to finish? The double catch is that every time you die the game re-installs all the objects collected since the last portal, it also resets the ammo. This makes collecting objects different from when you play with infinite lives, a death jump or leap to collect an object, will not collect the object but will transport you back to the last portal, which might be some distance away. You have to perfect all the paths that collect objects and manage to get to a portal and save them. It also changes the way willy re-appears back in a room after death. In this version that simply does not happen, he is moved back to the last portal. f you don't visit the portals then a death could take you back many many rooms and many, many objects collected. Those portals are the most important place to visit. If the game was easy in the standard format, then this version will not have any change in how you play, its design is for the casual player to permit wandering without real consequence. One technical change from JSW128 VK3 was that is Willy does not change colour when immune. This was changed to the room name changes colour when immune instead. This small change was to enable willy to jump on ropes when immune. It has an inbuilt cheat mode, which uses a different cheat code from all other versions. --------------------------------------------------------------------------------------------------------------------------------- In this demo version I have pushed previous attempts at upping the games speed into oblivion. The Title of the file is JSW VL5 demo.tap. Which has a lot more graphics than JSW 128 VL5.tap It does however display the fact it is a demo version.
