Just started playing the Bbc computer version just to note any differences,early days yet but there is good use of colour as I would expect from this computer,sound is adequate.

Hello by the way I am a new member,about time there was a forum about these games :)

Welcome. :)

 

As just mentioned here a moment ago there's a few differences, I do have them to check them out.

 

Is your's the tape or disc version ? Coming to think about it afaik they are the same for JSW1 at least although would be interesting to know for sure.

 

The JSW2 versions (tape / disc) are quite different, ie "Ethel The Aardvark" etc, although I've not played that version for a few years.

You know I had no idea there was differences between formats but now you have me curious. It is obviously through emulation and is a regular SSD file, so at this moment in time just looking at the game it I am unable to answer that question. It would take some time to be 100% sure as I would need to make a map lol.

You have me interesting in probing two versions of JSW2 if I have them.

As far as I'm aware the 'cut down' one would of been tape only originally. Obviously they are all SSD's now. The 'disk' version is larger and loads sections as you go along. For instance in the disk version moving from 'First Landing' to 'To The Kitchens' causes a disk read. The 'tape' version moving left from 'Macaroni Ted' takes you to the 'Fallout Shelter'. On the 'disk' version that 'Macaroni Ted' screen is awol its 'Bathroom' straight to 'First Landing'

 

There are other differences, the JETSET WILLY message is solid in one and pixelated in the other.

 

Really a good map of both versions is needed.

 

Here's two structure screenshots:

 

'Tape'

'Disk'

Note: The disk version will crash horribly if there's not enough memory (or sideways ram not checked) I had to scale it down to just OS/DFS with ADFS present (but disabled) and a DNFS rom it crashed. See my 'suggested' basic config:

I think a new topic for the B versions of JSW2 is in order however, if you wanted to make one I'll chip in bits and pieces etc. :)

I guess I should add some JSW1 B Screenshots now too:

 

I've not done all the rooms just a majority of them. The ending is the same however instead of Willy just falling into the Landing, he jumps twice, once to avoid dropping to the room below and again to avoid the nasty. The ending pics in this post will show.

 

Title Screens:

Game Over Boot Perhaps for this version that should be !BOOT ? :D

I've made a rough (on paper) map of the 'tape' version. I plan to assemble it into screenshots at some point. To summarize its got (most) of the 'space' rooms intact but the mansion is very small. No megatree etc. 74 rooms unless I've missed something.

 

Disk version needs mapping next although I think its not far off the C64 / CPC464 / Spectrum version in regards to its content. I'm aware of the 'extra' rooms in the C64 version.

I've uploaded a disassembly of the BBC version of Jet Set Willy 1. It's not yet as comprehensive as my Spectrum disassembly as I haven't done as much work on it. I have found a few initial pointers showing why it doesn't work properly on the Master series, and it looks like I'll be able to work up a bugfix to get it working.

BBC JetSetWilly 1 appears to have an identical room map to the Spectrum version (http://mdfs.net/Soft...SW/JSW1/Map.htm).

 

God damm it, how do you do proper links in this thing?

Thank you! :)

 

I did suspect that, the other versions I have to hand (not all posted just yet) appear the same Tatung and Z88 ( ! ) versions.

What browser are you using ?
 
Generally you can either:
 
1. Click the URL button just under the size dropdown and paste a URL in
 
or
 
2. Paste or type it in, if its does not link simply highlight the text and then click the link button to type in the URL.
 
or
 
3. Advanced users. Click the top left button on the editor to turn all the 'friendly' features off. "raw mode" in effect. Note switching between them while editing can have odd effects. I do use this quite a bit though as I'm used to typing in code.

 

The editor is better than it was however. I do have thoughts on this.

I was wondering if you managed to look into making it run properly on the Master series yet ? :) I guess not as I do not see an update although you never know. :)

 

My investigations so far reveal:

 

JSW2 'disk' version (the full one) works OK at least on MOS3.5 . I note it loads it all in rather than when running on the B, which is interesting as with BeebEm I have quite a few empty slots of SRam but it appears to ignore them. No matter. I may edit the code to load them in anyway to see what happens.

 

JSW2 'tape' version (the trimmed one) , does not appear to work properly, graphics are terribly corrupt.

 

JSW1 , similar to JSW 'tape' corruption although not quite as bad as JSW2, its playable-ish with immunity applied but it looks like the ZX version with the Attic Bug in full swing.
