Overview
editCool NES was the best and first playable NES emulator in Scratch until the release of aartNES. Performance in this emulator is quite bad, since with audio most games run at around 35 FPS, while without audio, most games run at around 50 FPS, still not full speed. It's unlikely that these issues will ever be fixed, since the emulator hasn't received an update since 2022.
It features support for 10 mappers and a menu which can be opened by pressing space, from which you can modify controls, reset the emulated console, modify the display and load a game. Accuracy appears to be similar to aartNES, albeit slightly worse due to having only 8 complete mappers and 2 incomplete (4 and 90), while aartNES has complete support for 10 mappers. It's accuracy in general appears to be worse than other NES scratch emulators aswell such as aartNES and NES Emulator v1.0.0.

Converting Roms
edit- Scratch does not allow you to upload files directly during runtime, so you have to convert the desired rom to hexadecimal string and load it via the emulator's UI.
