Hi everyone, I am the dev who has ported over MAME4ALL and FBA320.
Sorry for the long delay between releases. There will be a new version of MAME4ALL shortly.
In the current v1.1 of MAME4ALL for Dingux, CPU Cores doesn't do anything. There are no alternative cores for M68000 and Z80 and is just for future expansion.
As another poster stated, the best settings can vary depending on the game.
The two most important settings are Dingoo Clock and Video Aspect.
In many games, running faster than what is required is just wasting battery power. The best way to determine if you are running okay is to check the FPS (SELECT + RIGHT SHOULDER).
Video Aspect determines the rotation of the screen and the screen scaling used. It's probably a bit over loaded in that these two options should be separated out. Anyway choosing the right aspect (Landscape or Portrait) can make a big difference to a game.
The screen scaling is also very important, especially for high-res games such as Tapper and Rampage. One of the scaling options should be selected for these. Quality and speed are direct trade-offs here - the 'half-size' scaler is by far the fastest, the others give you different degrees of niceness. Added to this, choosing 8-bit or 16-bit modes will also effect how the scaler works. Experimentation is encouraged.
