The No$ (NoCash) programs are a series of proprietary emulators, some of which are donationware, and accompanying tools/debuggers for a variety of systems, produced by Martin Korth.
|no$gba||✓||GBA, Nintendo DS|
|no$nes||✗||Nintendo Entertainment System (NES)|
Don't bother with these unless you happen to use a very old/outdated computer, these emulators are built around speedhacks and are prone to bugs. Use the emulators for the systems listed on the main page instead. The exception being No$gba if you need some of its additional features such as a more stable link cable emulation support (which in the recommended option, VBA-M doesn't work properly as of recent builds).
