is it a recompiler issue?

ie is it still possible to break with -nodrc ?

there have always been reports of some 'random' bugs in games with the DRCs enabled, not sure why, although reports seem to have increased in the last 2 releases, again, not sure why..

A regression version on this would be very important, if there is one. Seems to be an FPU bug in the MIPS DRC; the graphics do straighten themselves out after a second or two and then you can play, but it's a definite bug.
