NO$GBA
What it is
NO$GBA is freeware for emulating Game Boy Advance, Nintendo DS, and DSi systems on Windows. The downloads page lists version 3.06 dated 14 Apr 2025, with Windows debug and gaming editions plus a DOS gaming edition. Its debugger presents Code, Data, Stack, and Registers windows, and the Data window can display or modify memory dumps. Source debugging supports .ELF, DWARF2, and .SYM information, along with execution timing and profiling details. Developers can use conditional breakpoints, tracing, and warnings for suspicious actions such as ROM writes or invalid memory access. Emulation can link up to four GBAs for multiplayer and save or restore complete hardware state to a file. An upload function runs programs up to 256K in attached GBAs’ Work RAM through an xboo cable. DSi emulation requires system files some users may not have. Martin Korth directs freeware questions to the forum and technical bug reports to email.
