I'm shopping for cartridges for my PAL XEGS system, but seldom the eBay seller states if the game is NTSC or PAL. I bought the NTSC version of Donkey Kong and the color is all off, the music plays too slow and sprites are flickering. The gameplay seems to go in normal speed though. When I try to contact the seller and ask about which region the game is, they usually reply that the game is universal and will play on all systems. This can in some cases be true. It would be good to know which NTSC games creates which issues when played on a PAL system. Anyone know of an overview like that?
As an example I would like to buy Pitstop by Epyx and the seller says the cart works fine on both systems. Haven't asked if this has been tested.
