Summary	00520: mp_twc: When you start the game you see only a black screen.
Description	When you start the game you see only a black screen. Follow-up by Pugsy in 0.122u2: Just for info (probably of no real use though...) I've traced it in both 0.101 and 0.122 and for some reason in the working version when it should hit 401a6 (or thereabouts?) it jumps back to the start at 000200, whilst in the non-working version it doesn't. If you BP 401a6 and then on it's first execution BPCLEAR and then PC=200 and continue it seems to work...and works again with no help even if you F3 it. temp0 = 0 ;bp 401a6,temp0++==0,{PC=200;g}
