Hi all, I'm trying to build a little ISO with the last mameox128 and with my favourites games. If I put all files on the HDU of my modded xbox, all works fine. If I put these files into a DVD ( I burn an Iso built with Xiso ) all works fine but when I try to use a Cheat, i got a message " Cheat database not found...." . Anyone knows these problem and the right solution ?? Thanks in advance. -=[ Ninjam ]=- P.S, sorry for my bad english..I'm not an english man
