NO$GMB

No$gmb is a emulator for gameboy, pocket gameboy, super gameboy, and color gameboy, allowing you to play any gameboy game on your PC, provided that you own a romimage of that game (a copy of the program in the real cartridge). Note that these games are usually copyrighted, except for a few freeware ones.Beside for the ability to play games it does also include a debugger with graphics user interface, conditional breakpoints, symbolic debug information, VRAM viewer, optional warning messages, online assembler, and various other useful things, making it a powerful development tool that is used by several professional game developers.Further features are emulation of two player link (on the same computer), screenshots, real CGB-colors, gamegenie and gameshark cheats, joysticks, snespads, digital sound, a color scheme editor to colorize monochrome games, etc. etc.The program is entirely written in assembler language, which makes it fast enough to run on older computers, for monochrome games a 386 with at least 33Mhz should be suggested, and for color games a 486 with something like 66Mhz.
