Oh I get it very well, believe me... But let's start slow.
Well, I see a max file size it can run in theory. Sure. Anything else? It supports about 99,.....% of the OFFICIAL database for Megadrive/Genesis etcetc blabla. Now the BUT...
Hacks are not guranteed as they are sometimes made for inaccurate emulators. Real hardware is not able to run them sometimes. And the bigger BUUUUT....
Aftermarket and especially games made after the cart's release date are out of discussion. Why? Because no one can forsee what tricks they add to the cart in the end. Some might be fixable by firmware updates, many not. If you want magic, then you are wrong here. We talk about facts! We don't accuse ppl of false advertisement out of no reason!
Ah and while we are at it... Where does Krikzz write: "Hey man and you can of course steal still in sale indie games and cause them to lose money they deserve! If new ones don't run three years after the cart's release I will fix it asap to allow moar stealing!" I am quite sure many here use ROMs off illegal internet sources, but they are smart enough not to talk about it and they get support. But you DEMAND support, accusations included, for a still in sale game with obviously no archival interests... lil bit shady that is...
Got my POV? I think you got.
