Description: From the Wikipedia page:
NO$GBA (pronounced "no cash GBA") is a free Nintendo DS and Game Boy Advance emulator for Microsoft Windows & DOS. It is capable of running commercial and homebrew Game Boy Advance and Nintendo DS ROMs, many at full speed. It is the first Nintendo DS emulator running commercial ROMs. However, this claim has been disputed by many in the emulation community. NO$GBA was developed by Martin Korth.

Note: This is an online installer. Since actual license information is unknown, the launcher download includes no program files and therefore should be okay to distribute through SourceForge still. Please do not talk about or ask how to obtain illegal ROM files below, I will actively attempt to have you dismissed from this site if you do.
Optional: If you want to use your own external BIOS files, place them in Data\bios and they will be moved accordingly. The list of recognized BIOS files are as follows: GBA.ROM, BIOSNDS7.ROM, BIOSNDS9.ROM and FIRMWARE.BIN; thanks to starrysky for that information.
