no$gba color issues

Hmm from what I can tell no$gba either unfixably (at this stage) glitches in that cutscene or it does not like save. I can't help fix the cut-scene but I can help return the game to normal afterwards, just save the game and close the emu and reload the game.

I warn you by the way that no$gba is a lot more problematic with it's saving than DeSmuME. It only writes the save to the HDD when another game is load, the current game is reloaded (not reset) or the emu is closed normally, without doing any one of these the data vanishes up to the last save that was done like this if the emu/game happens to crash. And even if you propperly confirm all your saves by reloading the game for instance then a crash could still corrupt the save so best back those up as well (they are in the battery folder). Using No$Zoomer first of all gives you some nifty zooming with filters at barely any resource hit and secondly it has a feature in it's File(F) menu called Save the output file(U) which when clicked writes the save to the HDD, or you could also assign a button to that function. No save states of any sort either (Snapshots only work for GBA games at this stage).
