#Fixing a paperboy arcade game code

I don't know if Game Genie works on clone consoles but it might be able to fix the problem bytes.Īccording to the emulator I used to check the code, the GG code would be PXNELEOK PENEGAAG (changing address $80FB from C9 40 to 29 01 to change the instruction from CMP #$40 to AND #$01, which should have the affect of button input becoming a normal 0 or 1 result). Apparently the Japanese version was fixed to read the controller ports more normally (maybe because Japanese games tended to have their controller code written a bit differently to support the external controller port on original Famicoms), though that version of the game seems to be a rare game so you probably won't get it. Commonly 'LDA $4016' or AD 16 40 in hex.)Īt least that is the case with the USA version. (the '40' result is what is known as 'open bus' returned as the last byte of the instruction used to read the controller port. Emulators smart enough to handle the garbage for compatibility will support the game, but clones that are not aware of this will not (a clone is absolutely an emulator, especially for this point of discussion) Most game programmers will filter out the garbage bits to get what usually results in a 0 or 1 value to indicate a button IS NOT or IS pressed.īut Paperboy does not, expecting to find the controller port to return 40 or 41 as the result.

TECHNICAL DETAILS: When an NES game wants to read the controller ports, the response the game gets is a byte with some useful bits but most of the bits are garbage. If it is not the exact game I remember reading about in some technical documentation to emulator authors, it still has the same technical oddity. Paperboy's compatibility with clone consoles might be because the game is poorly programmed. Okay, I had a random thought and so I checked.
