Sounds daft but i had a neo 2.2 in my PS2 once and THPS3, Splashdown did not work But when i got my neo4 they worked fine.
all i can say is if you want to play them get a neo 4 or messiah alot of people on this board lean towards the Massiah but which one you get depends on what you want with the messiah it boots all backups and all original imports , the neo 4 disables micrvision so you can record dvd's on to vhs it disables the region code and you can boot all backups and originals but it does not boot original import games.
the chioce is yours
