Castlevania III Sunken City Glitch

Post by zeroone » Wed Aug 12, 2020 7:26 pm

In my emulator (Nintaco), rarely, but sometimes, when I kill the final boss in the Sunken City level of Castlevania III, I see the following glitch:

I was wondering if this is a known bug, or if this is an emulation issue. I routinely beat the game and I never noticed any other problems. I was wondering if it could be related to the triple boomerang throw and all the segments of the bone dragon (that is, too many sprites being manipulated).

I found someone else encountering this glitch:

But I don't know what emulator was used to capture that video. This might be a real bug in the game.

You could also try the speedrun.com forums; if the glitch occurs on console, i'm sure someone there has seen it before...

I know CV3 does some crazy mirroring switching, like sometimes every frame, but i don't know anything more than that...
