I noticed a glitch in games with raster effects. Not all of them.
The affected games are :
World Heroes 2 and I think Wh2 jet too.
It doesn’t happen on the first world heroes or super sidekicks 3.
It’s a minimal glitch... only heavily noticeable in galaxy fight coz of the grounds are much bigger. Specially on kazuma scenario.
The ground pops every few seconds. It doesn’t happen in original cartridges. I tested.
Take a look on it, guys!
