It is recommend you use the stability feature. Why would you turn it off?

For better input latency. I'm looking at the LCD code and it mentions a double buffer. So I'm wondering if when you turn on stability feature it adds 1 - 2 frames of lag, or does it work like the GBA sync to core buffer that is really fast?

Code is mostly copy-pasted from GBA core. So it's very similar.

It adds about 0.4 frame latency to the 0-1 frame latency of the previous releases but that is at the top of the screen only. At the bottom it is 0 added latency.

If you disable stabilization then the maximum latency is 0.4 frames at the top of the screen and 0 at the bottom but you will have to deal with unstable video if you use a CRT or vsync_adjust=2.

Thanks for the detailed response. Glad to see you were able to use some code from the GBA core to help with stability.

Great work. Last update fixes a lot of scanline issues. But there are still some bugs while running "hi-colour" images like in rayman intro.

Found a great in-depth article about the GBC audio chip. I thought I'd share it in case someone here could find it useful:

it's almost generic audio amplifier. Just suitable for several audio outputs in GBC. It has nothing to do with sound generation.

You're welcome.
