Thanks!! Ill try it out . I have a couple of P.O.W bootleg boards with MASSIVE daughterboards in varying shape.. would be nice to replace them. Since atleast 1 of the games has some graphic glitchesI launch the game with MAME, I let the game playing a bit then I pause (letter p).I open Winhex, then I go to Tools/File Tools/Unify Bytewise (8 bit) then I select snk880.11a and snk880.15a (first ones read in snk68 MAME driver), and I save the file as part1.bin (256 kB).this sounds useful, please explain a little moreI think you can get your 4 roms from MAME, after launching your game and selecting each rom in RAM with an hex editor such as Winhex.
I open part1.bin with Winhex and I check in Tools/Open RAM : MAME (I use MAMEUI) if I find the beginning of the same block of 256 kB in Search/Find Hex Values.
I redo the same process with the other blocks.
