Summary 08540: nes [btoads and clones]: Game crashes at the start of Level 3
Description The game plays normally for the first two stages, but crashes to a black screen when you begin Stage 3. The normal background music plays but the game does not progress past that point.

I tested this with the US and European versions, and it also happens in a hacked Brazilian bootleg that I was testing for a friend. I have not tested this with the Japanese version.

I've attached zipped savestates for btoads and btoadsu made with the standard release build from mamedev just as stage 2 ends, before the cutscenes. This also happened in 0.250, so I'm not sure when it began.

I tested the Japanese version and it hangs in the same place. I also tried btoadsu in 0.228 and it has the same issue. Furthermore, there's a bannister forums post from 2009 saying the game breaks on level 3. Maybe MAME's never made it farther than that.

It wouldn't be the first Rare developed game that makes MAME go nuts. See 06902 and 05825...
