Bug Description

Binary package hint: visualboyadvance

Ubuntu 10.04 - 64-bit. I have not tested on 32-bit. Using the VisualboyAdvance package 1.8.0-5.

When playing a Gameboy ROM on VBA, the speed is far above 100%, and stays up at around 200-300%. If I throttle it to 100%, the sound and gameplay stutter and are jerky. I get poor performance on Gameboy Advance Roms.

What I expected:
Games to stay around 100%, with smooth frame-rate, as my system should be sufficiently powerful. (Intel 2.2ghz Dual Core, 3gb RAM)

What happens instead:
Roms are either too fast, and have stuttered playback, or perform poorly.

I have the same problem on similar hardware (Intel Core 2 Duo 2.66 GHz, 4 gig RAM) and 64-bit Ubuntu 10.04.
I have tested a few GBA ROMs and get speeds of over 200%. (this is with throttle=0 or throttle=100 in the cfg)
Trying to speed donw the emulation by using throttle valus of less than 100 gves choppy and jerky sound and gameplay.

It seems vba-m is the way forward. Not sure if someone filed a "needs packaging" bug or not.
