Some games have bugs right off the bat, others may have some weird glitches near the end of the game.
#COOL NES EMULATOR DOWNLOAD UPGRADE#
Q: Will the emulator ever run faster? A: Of course, there's all sorts of stuff that can be optimized! It's pretty difficult though, because there's no way to tell if a change in the code will increase or decrease performance… As always, the easiest upgrade is a faster computer Oh boy, here comes the technical stuff: Q: How accurate is the emulator? A: In terms of “how many games work?” I have no idea! I simply don't have the time to test every game and complete them. Games that use mappers are always larger than 40KB. Doesn't play any audio ¯\_(ツ)_/¯ Q: Why do some games run slower than others? A: It depends on all sorts of stuff, all you can do is hope that the game runs fast In general, games that use mappers will be pretty slow, so stay away from those if you want good performance. Q: Why do games have no sound at all? A: Because the APU (sound chip) hasn't been implemented! Even if I added it, it would just hurt your ears because the game runs too slowly… Doesn't mean I won't add sound, I just want to spare your ears Q: I looked at the code and found an APU sprite! A: That's just for the APU's frame interrupt. If you don't know what “mapper chip” means, then google “Nintendo MMC”. If you don't want to wait, has already made a GUI for the emulator! There's even instructions for converting ROMs on Windows: Q: I tried to load a game, but it says “Unsupported mapper X!” A: That means the game's mapper chip isn't supported yet. Q: Why is it called “Cool NES emulator?” A: Because I suck at naming things Q: When will it have a GUI? A: When I have enough time to actually add one. Alright, since this emulator is finally getting some attention, here's the obligatory Q&A forum post.
