Let me say this.
My PStwo may be just one of the good ones in the batch. Although it heats up to levels I don't really like, nothing is wrong. I play for hours and hours and no problems whatsoever. I've had it since October
And, secondly, with a Crystal Chip installed, it acts the exact same way as before, except booting backups and such.
Is that modified version not working?
The current modified version of 0.7 I have is working fine. I'll wait till I'm sure this one is working before I upgrade.
