Talk:WarioWare: Touched!/Version Differences
Mona Pizza GBA Cart Check
Copying the following from what I said on the other talk page:
I looked at all the roms in a hex editor, and I am reasonably certain of the following...
Around 0x00006000 to 0x00007000, the rom stores the Title ID of the GBA game it looks for to unlock Mona Pizza.
Japanese Rev 0,1,2, and 3 all look for RZWJ, WarioWare: Twisted! Japanese version.
USA looks for RZWE, WarioWare: Twisted! USA version.
Europe looks for RZWP, WarioWare: Twisted! unreleased European version.
China and China (Debug) look for AZWC, WarioWare, Inc. Mega Party Games$! Chinese / iQue version.
And the USA/Europe Kiosk Demos, Korean version, and DSiWare ports all seem to exclude this line of code in their roms.
