This is certainly an interesting revelation: we've found now that with some copyright protected games, and possibly others that wouldn't load before, that if you use a PAL bios, the game works. This has now been confirmed for both NTSC-U and NTSC-J games.
Can somebody else confirm what lilo said, that by using an NTSC-U bios on a PAL copyright protected game it might work?

Haldrie: Thanks for that. Indeed, I missed your reply. I'm glad my theory has turned up some interesting results.
I still have the sneaking suspicion that it has to do with the specific type of protection being used... but until I can find a list of at least *some* games that mentions the specific type of protections implemented in the game, I have no way to test this theory. A patcher would be helpful to figuring this out, since it seems that most all of the games that work from this theory can also be patched... it'd be interesting to hear from a patcher what makes a game patchable or not patchable.
Thanks again everybody... I will continue to seek more answers on this topic.
I just tried the game again with the SCPH1002.BIN bios (EU) and it works for it too. The game's frame rate is 60FPS with each bios. I played a bit in-game and it seems to be running perfectly. I even tested the 3D battles in the duels and I can't see anything wrong with the emulation.
And yeah I just recently figured out that SCPH7003 was an Asian bios. The game also runs on SCPH-1000 (J) bios.
Also, I can never get the SCPH-5520 (EU) bios that I have to work though. It keeps showing "r3000: executed illegal opcode" with 14 different hex codes after each line and just stays a black screen afterwards.
