School security is not gullible, unless the software is. I go to school here; I would know. And I've always been hacking around their security on my free time. If you get a No Permission message, trying to bypass that, like creating a shortcut or executing it from another method, is about as feeble as trying to bypass a vBulletin forum No Permission message: All possible ways are blocked, because the command itself is blocked for the underpriveleged user, not the PHP that links to it.
Now, first off, Toasty sort of jumped to conclusions, but he's right: This guy seriously needs to use upgraded hardware, UNLESS the slow emulation speed is caused by the game where the graphics fail to load, and believe it or not, this will happen with some games. If you use Jabo's Direct3D with these kind of games, say, Indiana Jones and the Infernal Machine, this slowdown to 6-or-so FPS will not occur, but you get a microcode failure. The fact that a shitty OpenGL plugin worked for him but not any of the DirectX plugins does not prove, for absolute certain, it's his system, either. 1964 OpenGL bypasses microcode failures, giving you a black screen for those games, and probably crashing sooner or later.
I'm only saying, I'm not prepared to jump to blaming his hardware yet. It could be the game he's trying to play or the emulator he's using for it. Take Top Gear Overdrive as an example; using Project64 with that game with somewhat below-spec cards is miserable while on Mupen64 it's all fixed.
