Pokemon XD repeatedly freezing told to disable dual core

[JMC47]

Regardless of whether Single Core is slow or not, it'd be pretty nice to know whether it froze or not on Single Core. If it's a CPU/GPU desync, there isn't much that can be done with it. You could try the Dualcore Netplay branch and see if that fixes the crash (it randomly fixes other games, too, so it's not out of the realm of possibility.)
