That's right i'm not Japanese. What's that got to do with it anyway?
Been on holiday for a week so I've missed some things. Good to see that Franxis has been busy with release 2.5 of MAME GP2X and incorporated samples and the new Z80 core. Thanks Franxis!
I've made some good progress with the Bally Midway drivers and I've improved the screen stretch modes and will explain why:
The interesting thing with Rampage and Spy Hunter and Tapper is that they are all have resolutions of 512 x 480 which is way too big for the GP32 screen. Half the resolution (256x240) actually fits quite nicely so that's what they are displayed as - but you have to set the stretch mode on.
Rampage and Tapper and Discs of Tron play really great, but I'm still having some wee problems with Spy Hunter. But I'll get that sorted out.
I'm also trying to get "The Empire Strikes Back" fully working as this quits about 1 second into the game. This is a protection issue and fixed in a later version of MAME.
