Thanks Guys, Im running a P4 so it shouldnt really be my processor (I would have thought). I will post my other specs when I get home from work.
Depends on how fast your P4 is. IIRC, a P4 @ 1.4 Ghz was about the same as a PIII @ 1 Ghz, which IIRC isn't enough for MK anymore, let alone strider2 (which needs about 2 to 4 times the proccessing power to emulate as mk). Add to this, strider 2 is still WIP with imperfect graphics, sound, and other emulation.
Anyway, just in case your newbieness

includes you not yet aware of the "emulation slowdown", the system doing the emulation needs within about an
order of magnitude of 10 times better than the processing power of the system being emulated. And since mame doesn't like taking shortcuts that change the play, it's in the higher end of the range (call it about 20-40 times generally). Hmm, since the new official mameFAQ is down ATM,
link old mameFAQ.
