Gngeo2X Universal Bios Samsho5 But Svc Cheat Came Up.

[rsuryase]

I'm playing samurai showdown 5 on gp2x using gngeo2x 0.7 and universal bios 2.3. The cheat that came up is snk vs capcom, why is that? File name is samsho5.zip and inside is 270-xx.rom.

I have samurai showdown 5 special and the cheat came up right, so did snk vs capcom game.

Well, I can confirm this happening, but I cannot find an answer. Did you try sending a note to the unibios developers?

 

[rsuryase]

I'll email them.

Did some research. Found the game id is read at 0x108 in program rom (270-p1.rom). Checked with a hex editor. Yours shows 6902 (269=SVC). Replaced with current p1 rom from mame (copy /b 270-p1.bin+270-p2.bin 270-p1.rom) and retested. Got a bank error. Will have to fix entire romset. Changed ID to 7002 in old p1 rom and now cheat db works.

Yeah, fixed. Wished I'd taken computer science in college.
