The cheat engine in MAME 0.127 requires individual xml files for each game due to a complete rewrite of the cheat engine by Aaron Giles.

I've coded a conversion util and I'm still in the process of optimising the cheat.dat file for conversion. This work is nearing completion (~99.xx % complete). However, I've decided to release the converted 0.127 cheat files as they stand via the forums. There will be issues with the the cheat file and the cheat engine still - more widespread testing should hopefully uncover more..

If you spot any cheats that have issues please post a bug report in this topic, thank you. BE AWARE THE LATEST XML CHEATS COLLECTION NOW REQUIRES MAME 0.127u3 or LATER

NOTE this cheat release is based purely on the cheat.dat file for MAME 0.126. So it has no cheats for the games added between 0.126 and 0.127.
