Both versions have their pros and cons and both dont have 100% compatibility.
Uae4all2 is the best version I've used as it's highly configurable with hd/whdload and cpu/ram options and higher compatibility. It will probably struggle on 3ds with anything aga related.
With your ported version...
Just tested this excellent work so far!
Did you use the source code from the rg350/gcw zero version? It's based on the dingoo source code which has lots of issues with slower sound rate and missing graphics especially in flight sims.
I have the gp2x version and it doesn't have any of them...
Is anyone familiar with former forum opg.life ? I missed the transition to the new forum over the week end (was scuba diving in the sticks with no internet connection). If anyone in touch with any members please pm me.
