I bought one of this a year ago. I hope it's the same model as mine.
Sorry first of all. My english is really bad. Respect the games:
DOES NOT WORK AT ALL: Archrivals -- Also works on mine Bulls Vs. Blazers - Also works on mine Desert Strike - Works James Pond [although James Pond 2 and 3 both work] - I don't know Zero Wing [so I guess all my base are belong to NOBODY, huh?] - I don't know LOADS AND RUNS BUT UNPLAYABLE: one version of Stargate (scrambled graphics) - I don't know Super Bubble Bobble (can't get past the opening background scenery; sound is just a constant buzz) - Confirmed non working WORKS BUT NOT WITHOUT ISSUES: Lotus Turbo Challenge (there's a constant high-pitched noise) - I don't know.
About my problems with games:
NOT WORKING:
Nba Jam T.E.
Nba Live (any versión crushes at the beggining).
Fifa (same as Nba Live).
Some other versions of EA Sports's games.
LOADS AND RUN BUT UNPLAYABLE OR WITH ISSUES:
Contra - Bad synchro
Light Crusade - Runs but when I create a new game, crashes.
Lion King - Same as Contra, and also crashes.
Probotector - Same as Contra.
Zool - Crushes after seconds of play.
I still test some new roms. I don't know if it helps or not. I'll refresh this list with more if you want.
Thanks ^^ AAAAHHH!! - Frogger works on my portable
