not sure what no UMD is... but I use the M33 Driver on the UMD mode:
and I am able to play my back-up games, and they are the following:
- Jeanne D'Arc (sold that game already)
- NBA Live 08' (this game is sold already too)
- Midnight Club L.A. Remix (this game rocks.. great music)
- Crisis Core
- Super Robot Wars Portbale MX (this one is great, but if you can't understand Japanese, don't play it)
- DJ Max Portable (wicked game)
- DJ Max Portable 2 (even more wicked game)
I am still waiting for my DJ Max Classiquai Edition from Ebay.
that's all I can remember now... half of the games I have played have been sold already.. I have the habit of finishing the games and selling them.. only the DJ Max games are with me know and the Crisis core...
