Pretty sure that it can be infinitely high; the only limit is filesize; for example, if you make one of Link's textures as 1024-2048, but the others as 8, it will probably work fine, but if you have all of them be that hi-res, it'll crash.

P.S. Riivolution is even more flexible to filesize, though, so you can probably have it not freeze if with Riivolution; it would just be really laggy.
Damn, well I might as well just keep it at 512x512...
Thank you!
