I'm currently trying to get into this game. I made several attempts already (still practicing though) but ever now and then i seem to encounter a freeze after beating the Stage 1 Boss. I'm not sure what's the reason for that but it appears most of the time i was using Bob. Is there anything i need to avoid to make it happen? It doesn't happen often but it'S annoying to have to restart the game and run Stage 1 again.

I've never had that happen once in ~1500 attempts, and never heard of this happening to anyone else, so I don't think that's normal. All the glitches we know of in the SNES version are just graphical and don't affect the speedrun.

I'm not really an active runner of this game, but to facilitate further discussion I think we need more information. Playing on emulator or console? My first thought when hearing of strange game locks is to ask if you're using a flash cart. I've had very strange things happen with my FXPak simply because the SD card I was using was failing (Pretty much any SD card you buy on Amazon is a cheap knock-off/counterfeit and are very prone to failing).
