I have a scph 75004 (i don't know number version) with matrix infinity + fw 1.75. All backup work well except espn nba 2k5 pal (english version).
Ps2 show playstation logo + fw version and then after a little read on dvd it stop loading and tv screen is always black.:cry: :cry: :cry:
On v9 with infinity orange dot + fw 1.75, the same settings, that game work well.:crazy: :crazy: :crazy:
