Mega Man - The Wily Wars

[GoogleCodeExporter]

When game is unpatched, speed/audio is slow but SRAM works. When game is 
patched with SRAM patch by MottZilla...game speed/audio is perfect but will not 
use SRAM to save. Can this be corrected either way so speed/audio are in sync 
and SRAM is working?

Original game is region protected and only works on PAL Mega Drive, thus 
running slower (50hz instead of 60hz) than on NTSC Genesis.

What Mottzilla's patch does (apart from replacing EEPROM access routines by 
traditional SRAM routines) is removing region lockout and force region to USA 
in ROM header, so emulator detects it and use NTSC Genesis emulation instead. 
Saving does not work anymore as Genesis Plus GX assumes the game still use 
EEPROM.

Anyway, to get the original ROM running at 60hz, you only need to force "System 
Region" to USA once the game has been started (after the SEGA logo generally).

In the mean time, I guess I could improve EEPROM game detection so the emulator 
makes the difference between original & patched ROM but in general, I would not 
advise using patched ROM, every existing original ROM should be emulated fine 
by Genesis Plus GX and there are enough options to customize the emulated 
system so they run exactly as they would on a real console.

Can you possibly improve EEPROM game detection so the emulator makes the 
difference between original & patched ROM....thanks again....

Hmm... I surely will.
But if you want original ROM to run faster, just do like I said.

Patched ROM detection fixed in r648
