What NO$GBA is
NO$GBA is a freeware emulator for Game Boy Advance, Nintendo DS, and DSi. The downloads page lists Windows gaming and debugging versions, plus a DOS gaming version; the latest listed release is v3.06, dated 14 Apr 2025. Its debugger presents Code, Data, Stack, and Registers windows, and the Data window can display and modify memory dumps. For source debugging, it supports .ELF, DWARF2, and .SYM information and shows execution timing and profiling details. Developers can use conditional breakpoints, trace execution, and enable warnings about operations such as ROM writes or invalid memory access. Emulation features include linking up to four GBAs for multiplayer and saving or restoring the complete hardware state to a file. An upload feature runs programs up to 256K in attached GBAs’ Work RAM using an xboo cable connection. DSi emulation requires several system files users may not have. The maker is Martin Korth. Freeware questions go to the forum, while technical bug reports go to him by email; his developer contact is not for gaming questions.
