From GameBrew - a wiki dedicated to Video Game Homebrew.
This is a SEGA Master System/Game Gear/SG-1000 emulator for the NDS, it can also play some Coleco games if you add it's Bios.
- Most things you'd expect from an SMS emulator.
- Correct sprite collision and overflow.
- Speech samples.
- YM2413 emulation.
- EEPROM save for the few GG games that use it.
- Download and extract file, DIDL patch it (depend on flashcard).
- Create a "S8DS" directory either in the root of your card or in the data directory (eg h:\data\S8DS).
- Put games on flash card, max 512 games per folder (shouldn't be a problem if separate SMS, GG, SG & Coleco games into different folders).
- Filenames must not be longer than 62 chars.
- You can use zipped files (as long as they use the deflate compression).
- The emulator should also recognise SMS games for SEGAs MegaTech arcade machine and 2 of the SG-1000 arcade games (using MAME zip files).
