This emulator seems like it's stable and all that, but the audio is a bit wrong. The sound/music is way too dark compared with the original systems audio, and one example is the intro misic in Alex Kidd in Miracle World. Doesn't sound right.

Other than that, there's only one thing left that I miss, and that goes for all the emulators written/ported by yongzh; the ability to turn off screen filtering when scaling the image to fit the whole screen in higher resolution mobile devices.

I want big squared pixels, not those filthered one. If only there were an option in the settings menu to turn off the screen filtering...
