Thanks for the feedback.
Just in case anyone is going to play with the new RetroPlayer feature, I'll post some MX2 specific experiences:
First of all, yes it actually works and the MX2 hardware is powerful enough to handle emulation of most systems up to the Playstation (though not all PSX games are running at full speed).
In order to achieve reasonable performance you need to disable the rewind support in the global games settings. Basically only 8-bit systems are fast enough even with the rewind support enabled.
You need to pick the right emulator for every platform, preferably optimized for mobile devices (ARM).
Here are the best cores to choose for playing on MX2:
- Nintendo (8-bit): Since Nestopia is currently broken and only shows black screen, the best core is FCEUmm.
- Super Nintendo (16-bit): SNES9x-2010
- Sega Genesis (16-bit): Genplus
- Playstation (32-bit): PCSX-reArmed (some games are slow)
It is pretty cool to play e.g. Worms World Party (the PSX version) on MX2 in your living room!
