The Sega Genesis/Mega Drive emulator is flawed
Who else has problems with the Genesis/Mega Drive emulator?
Sounds like it is the worst emulator on the device.
There are sound and gameplay problems.
That's weird, mine seems perfect, with no problems at all. In fact, the color looks much better to me than on the real Genesis.
i agree the biggest issue i've had believe it or not is the GBA emulator, it's not a big issue just some of th games don't run, all the others are perfect.
Have you tried the updated MD.sim? If you have, install Dingux. It's not that difficult and Picodrive runs Megadrive games fantastically!
I've never had any issues with it, I've got tons of Megadrive Roms on my SD card, haven't tried em all yet but no problems so far! 
yeah I updated but didnt use dingux and if people really think that sonic ran full spead on that fix they really never played a real Megadrive... I even did I side by side comparason and it was running maybe 75% speed.
anyways I think I'll install Dingux on mine soon
yeah its slow sonic plays at like half speed I believe. it needs some work, but at LEAST it works.
