Here's an updated SDL-VICE version for the A320 (OpenDingux), Dingoo A-380 and A-320e by Alian Gray. It is a first 
version of VICE 2.4 for Open Dingux with sound.  ;D

What is VICE?
VICE is a program that runs on a Unix, MS-DOS, Win32, OS/2, Acorn RISC OS, BeOS, QNX 4.x, QNX 6.x, Amiga, GP2X, Dingoo, Syllable, SkyOS or Mac OS X machine and executes programs intended for the old 8-bit computers. The current version emulates the C64, the C64DTV, the C128, the VIC20, almost all PET models, the PLUS4 and the CBM-II (aka C610)

Note: Compiled with the OpenDingux toolchain. Remember to change the resolution from 320 pixels to 400 pixels on a Dingoo A-380 (with factory kernel) and a Dingoo A-320e. The sound has been tweaked for the Dingoo A-380 and might need some changes for the Dingoo A-320e and Dingoo A320 (OpenDingux).


Short help for OD
So, after few days this is the fastest set up that I made so I would have the most fps in Laser Squad intro but without music distortion:
A320 SETUP for highest fps
SID chip 6581 (FastSID)
Buffer size 40
Fragment size Very large
Frequency 22050Hz
Synchronization method Flexible
Speed settings ->Refresh rate -> Automatic

That gives the 46 - 50 fps in the intro.

Now, It is possible to make a setup that has less fps, but the sound would be much better. You don't see many dropped frames with this setup, but fps number is lower. You should have in mind that many games for C64 would still work at 50fps with it (I tried Bounces, Lazy Jones, Lasersquad in game, Boulder dash, Antiriad... etc and they worked at 50fps)

A320 SETUP for most games with quality sound
SID chip 6581 (FastSID) or 6581(ReSID) (slower than FastSID but better sound)
Buffer size 40
Fragment size Very large
Frequency 44100Hz
Synchronization method Exact
Speed settings ->Refresh rate -> Automatic

I hope that this will be helpful to anyone using it in OD.  ;D

The main difference is that A380 is faster than A320 and so A320 has to have different settings.
By the way, this should be posted in Dingux-releases part of the forum too. It is a releas for OD too, isn't it?

Emulation is still not perfect and there are sound glitches, so be sure to visit here for setup and to comment:
