JustBurn has released a new emulator, called Pokemini. Pokemini emulates the Pokemon Mini, one of the world's smallest video game systems ever, which was released in 2001 by Nintendo.
The current version is 0.43. However, Pokemini is still in early alpha-stage, so don't expect everything to work 100% accurate.
Pokemini is available for the following platforms:
Windows
Linux
Nintendo DS
PSP
GP2X Wiz
Dreamcast
