pryzm and neokey help?

[Darthus]

Ps2 v4
No solder mod chip
neokey/sbox mod chip (for 80 min games)
gameshark 2

I've been trying to get pryzm to work for the longest time. When I swap it in, it goes to the black screen after the gameshark, like it's a real ps2 disc, and it spins up, to the high pitched part, but stays there, and doesn't keep loading.

It's not an 80 min disc, so that can't be the problem. Could it be because it's a PAL disc? It does the same thing regardless of whether I hold down the eject button for the no solder chip, or use the sbox method. If it's a pal problem, I haven't been able to find a pal-ntsc patch for it.

Also, could anyone give me some tips on using the sbox? It seems VERY picky. I have about a 1/8 success rate with it. With gameshark 2, are you supposed to turn on the sbox, eject the gameshark, put in the burned disc, push eject again to close the tray and then hit X JUST as the tray closes? Because that's all that's gotten it to work, but it seems VERY picky about when I hit X. Any tips?

Thanks a lot.
