The best Amiga emulator we have is Janus-UAE that is based on a very old Amiga emulator that is way outdated compared to WinUAE or FS-UAE. I know it is not an easy task to bring a later Amiga classic emulator to AROS, but it is in my opinion maybe the most important task to bring inn more interest. Now that AROS 68k is so compatible with Amiga classic it would be great with a version of AROS where everything is set up and ready to go. As most know WinUAE can be tricky to set up with roms, HDD etc.

What always been strange and kind of sad is how bad VICE work on AROS. The sound is very distorted, almost not possible to hear anything. With all the talented people that do compiles for AROS I have a feeling this could be solved. I consider AROS a part of the Commodore family and a good working version of VICE would be a step in the right direction.
Anyone up to the task? I would be more than happy to test. Last version we have is v.3.1 now VICE is v.3.4 and it can still be compiled with original SDL I'm told.

Edit:
I tried 2.4 and there Audio is working good but the emulator is unstable. Suddenly drops to half the speed etc.
Running the version without sound everything is perfect. It is something with the audio that is very wrong.

VICE 2.4 is the version used by Retrogames Ltd on their TheC64 machines. It's still a good codebase. While fine-tuning it for Icaros inclusion, I had to change some options to let the sound work OK without wasting too much CPU clock cycles. I don't remember what I did, though. Sorry.

Hi Paolo, Ok, thank you for the reply, good to know they use 2.4. In 2.4 sound works good but the emulator seams unstable. Work great for around 10 sec. then fps drop even without doing anything. Maybe Core2Duo 2GHz is to weak. That seams crazy but VICE is heavy on the CPU. I read somewhere that if compiled with -o3 or something the emulator is much faster.
I will try VICE on a much faster machine and see what happen.

I tried 2.4 on a very powerful computer. Nothing changed. It is very unstable, it is what I would call interference somewhere.
