This is a very simple 'loader' I sometimes use when working with original (with bugs) versions if required to quickly apply patches. It may be more use on a real machine or cases where you want to emulate the tape loader in full rather than apply (via an emulator) a .pok file.

It was purposely made quite simple and is played before the main JSW tape as it uses that to still load the game rather than having its own loading routine. This did mean I had to number the lines a little bit oddly to 'fit in' however. :)

 

The following POKES are applied via the patch:

 

The four 'official' Software Projects POKES:

 

56876,4 = Change the earth cell in The Banyan Tree to water so Willy can climb the tree

59901,82 = Fix the invalid arrow data in The Attic aka "The Attic Bug" that caused game corruption

60231,0 = Remove one fire cell from The Conservatory Roof allowing Willy to collect all the items present there

42183,11 = Remove the invisible (and unreachable) object from The First Landing and move it to The Hall

 

 

The codes to disable the keypad code entry page (as there seems little use in it these days)

 

33979,135

33800,202

34483,195 (This one changes it to accept any code so is probably not required)

 

 

SkoolKid's Pause Mode bug fix (as this one seems to work very well) , this only tend to occur if an Interface 1 is present however on real hardware:

 

35615,62

35620,219

35621,254

 

 

My small contribution / addition towards the Pause Mode bug fix is this single poke which simply prevents the game auto pausing if the in-game tune is off (it does not pause if it is on anyway)

 

35518,0

 

 

Enjoy! :)
