Also can look through this to see what Games have been tested.

Edit: As for the SFIV Taito Type X2, Runs pretty good. Runs at 75-85% Speed In-Game. But otherwise runs. Device does get Warm, but nothing to worry about. Seems like SSFIV:AE runs better
Edit 2: However, best not to try and watch the Attraction Video. Otherwise, Game will Lock Up on you
Edit 3: OK, more observations of running Taito Type X2: Depending on where you get your Games, you might not get them to run. I have tried a few Sources, and other than the one type I have of both SFIV Games, I cant seem to get any of the other Copies to run. Always get JVS Error. Even tried a Version that comes with a Loader Front-end. Same thing. Not to mention, cant even get the typex_config.exe to run. Keeps crashing on me for any other of SFIV I get (standalone and Super). Way I figure it, you need to get these types:
SFIV: Need the Version that comes as a .exe to extract to a Directory of your choosing
SSFIV:AE : Basically the Version that comes WITH a #JIMBO Directory when extracted. Will have the following
setup.exe and setup.2 through .7 .
Both work great. But as I said, for SFIV, you can not watch the Opening Video. Looked into it, and apparently there is a problem with any Copy of it out there. So just start it up and Play. Also, there are Trainers for both, but would suggest finding 1 that works best for you. SSFIV:AE does come with a Trainer, but that one seems to be working iffy to me. Seriously wish cheathappens made Trainers for it.
