I tried a rom WEC Lemans, and it shows on the warning screen & says the game works, however there is a warning that says the colors are incorrect, sure enough there are like 8 colors in the game on my xperia play, yet I can play the same WEC Lemans rom on my pc, in a powermame version of mame, and the game is perfect, therefore its not the rom thats at fault, but the version of MAME. Hope that makes sense and clarifies the game incompaitability issue some what.CheersGav.

I hear what your saying, and have experienced that issue before.

I have found its usually the version of mame that is at fault, I've had over 1000 mame roms since 2002, and some versions of mame show all the games available on my pc, when a different version of mame might only detect 500 or so games even though I still have 1000 roms.It's all about finding a version of mame that 'detects' them all, typically powermame for pc works best from what I have found.Also keep in mind, this version of droid for mame is 0.37 or something to that effect, where there have been years and years of updates to mame for PC since 0.37 was current.
