I'm trying to play Tekken 2 the psone version. I put the folder named SLUS00213 in the GAME folder. In the folder are this files: DOCUMENT EBOOT.PBP KEYS.BIN When I start the game, warning message appears, with all warnings off playing the game, and this kinda things. Then, the Screen turns black and it the game freeze and the PSP shuts automatically down after 10 seconds. Do i need popsloader to play psx games? P.S: I'm using 3.90 M33 and went to dark alex page and couldn't find any popsloader for this firmware.
