flashmasta savegame fix

Cotton: Non-patched version throws up a 'Flash write error' when you try to make changes in the options menu. Patched version removes this error but the high score table is completely glitched and displays a bunch of random numbers and symbols. The game has no level select so it doesn't really need a save feature but it's a shame not to be able to save high scores.

Hi, have you followed the last step of the readme.nfo ?

After applying the ips patch, you have to create a new rom by copying twice the same patched rom.

rom structure :

[program+data][save]

The patch relocates the save area from the end of a 8 mbit cartridge to the end of a 16mbit cartridge

If you don't do the copy, the physical cartridge will look like :

[program+data][save][random garbage][random garbage save area]

Thus, the patched game will read the high score table from the garbage area, resulting in crappy display.

The easiest way to fix this is to create a new rom structure like :
[program+data][save][program+data][save]

Under Windows, you can achieve this with : copy /b file + file double_sized_file

Thanks for the reply!

Ah I see, my bad. Should I do this with Biomotor as well? That might solve the options menu glitch.

Forgive my ignorance here but I don't understand how to make a new file using 2 copies of the old file. What exactly do you mean by "under windows : copy /b [patched_rom] + [patched_rom] [to_flash_rom]"

EDIT: Never mind, I figured it out! Didn't realise you were talking about using the command line. Cotton works fine now, Thanks

EDIT 2: Just tried following the same steps with Biomotor Unitron and it still crashes on the options menu, strange.
