Hello, elemental!

Recently I tried playing "Battletoads vs double dragon" and experienced a major glitch in NES emulation - screen went black right after level start. I'm writing it here because you said that you have totally rewrited NES emulator for the greater good, but this ROM run absolutely good on previous version of emumaster before rewrite.

After some digging I figured that render mode affects this problem but doesn't solve it. If you set render to "tile" or something without "all" - level will start without problems but then, after some time, the game itself will freeze. Changing frameskip and sprite limiter also doesn't help.

Any ideas why the ROM stopped working?
