First of all congratulations for this great and the best GB emulator for S60 vampent, you guys rock!!.
Secondly I've some sugguestions for your next vBoy version:
- N-Gage (first model) is stereo, as I can see you've implemented stereo for some devices, so it would be possible to include the N-Gage in that list?
- There's frameskip on the emulator, I know it runs fine but I've noticed it when using some fighting games and some fireballs lacks 1 frame or so. Maybe the frameskip is set in 1 or 2?. It would be great an option to select the frameskip

(this option would be interesting in the vSun emulator

)
- The sound isn't perfect as the topic of the section says. Some sound effects are lost in some games I've tried (for example KOF '95), so I think this part would be improved
Nothing more about this emu. It's the best and probably would be in the future.
Greetings.
