This game doesn't play on Jnes, Gives an Error: Mapper #232 unsupported.
I'd really like to play this game on Jnes, It's the only NES emu I love using.

There's a hacked version ([h1]) that will work, try that.

Mapper 232 doesn't sound right, try autodetecting the mapper using nestopia and patching the rom.

Quattro Adventure (USA) (Unl).nes comes up as 232 in nestopia and works fine (in nestopia) Maybe it isnt a common mapper?

http://tuxnes.sourceforge.net/nesmapper.txt says 71 though?

EDIT: attachments still broken?

EDIT: setting it to 71 works in nestopia, and it works in jnes too it seems
Color differences are due to using ntsc rendering in nestopia (you can set this in jnes too but fullscreen only)

Forgive me for being so Blunt, but how do I go about to patching the game in order for it to play in Jnes?

[smcd]

I used nestopia's edit ines header functionality (found in File menu) and changed it. There are tools to edit the header too (find them on romhacking sites)

Or if you can use a hex editor, Nestopia modified the 7th byte from 0x81 to 0x71 and the 8th byte from 0xE0 to 0x40

Additionally you can find a tool in the "Read me first" section or something in this forum, called "Rom Center" it basically verifies your ROMS are correct, headers etc. i would download and use that program on your collection

Well I managed to get the rom to work in Jnes, But no matter what game I select, it always plays the dizzy game. Thanks for the help, It was worth a shot.

^ when the mapper or Rom K sizes are wrong it usually means a bad dump.

Mapper 71 is correct for Quattro
