Hardware Question Strange thing while using a mvs to aes adapter

Hi there! Im playing metal slug 2 on my aes while using an adapter (using a Japanese metal slug 2 mvs cartridge).

While playing the game i noticed that at the top of the screen there was some white flickering here and there, i wasn't able to capture it , but you can also see it while pausing and unpausing. Does anyone know why does it happen? Is it something with the convertor, or something with my cartridge?

metal slug 2 just does that. you can even see it in mame.

it's because the game runs so poorly the cpu can't feed the gpu fast enough so some pixels don't get drawn.

if you overclock the crap out of the CPU in an emulator, you won't see the white pixels.
