Ok at least Marvel VS Street Fighter (CPS2) works almost perfect. I hope that they make progress on new firmware and emulators.
I tested the Super Nintendo (SFC) Emu and its quite good. Mortal Kombat 1-3 doesnt work, but some others work perfect, Many RPGs and Sports Games.
It seems CPS2 runs best (some speed issues on some games but other than that, very good working).
NES got some weird colours, or is my memory just so bad ? i can really remember how it looked back then, but well those have been 50/60hz TVs.
Some of the best Titles for Neo Geo dont work, most of them have bad GFX issues. Others dont seem to boot as it gets stuck in the Neo Geo Logo Loop.
Sega Mega Drive works pretty well, except for the sound (sound speed and sound lag) Hope that those get fixed because Mega Drive is one of my all time favorites.
I also got the one with the decent MPS Logo (which looks better than the MPS with the crazy Font in my opinion). I am still a bit disappointed by the screen, maybe i will open it up and see how it is connected, maybe i will install another screen with the same resolution/interface.EDIT: I found out that the reason why not so many Neo Geo Roms worked is because i somehow got BAD Roms.. i found a place with correct ones, now almost everything works.. Yes..
