Here is my plan:
Following machines will get a the new MAME4ALL v2.0 release:
(There are so many changes to MAME4ALL v2.0 that this is basically a new version of MAME4ALL.)
GP2X, Wiz, Dingoo A320, Gemei A330, GCW-Zero and Pandora.
Following machines will get Mame 0.69 and Mame 0.84:
GCW-Zero and Pandora.
All hosts have my new improve frontend which includes image snapshot support.
I'm currently working on the Mame 0.84 version on the Pandora - hooking up Cyclone and DRZ80.
At 1000hz, the GCW-Zero is a very capable machine. There's nothing wrong with it. It's certainly faster than my Pandora Classic clocked to the standard 600Mhz.
For example: if running a game which has, say, the M6809 core like Dragon Spirit, it runs much faster than the Pandora version.
Of course this changes when running M68000/Z80 games thanks to Cyclone and DRZ80.
Both GCW-Zero and Pandora has very capable screen scaling mechanisms and excellent controls. The Pandora slightly better in this regards thanks to it's keyboard.
