Szukam Genesis Plus GX

BlastEm is an open source, higly accurate emulator for the Genesis/Megadrive that runs on modest hardware. It is the first emulator to properly run Titan's impressive Overdrive 2 demo and it is the only other emulator besides Genesis Plus GX that can properly run the original Overdrive. It is the only emulator other than Exodus that passes Nemesis' VDP FIFO Testing ROM, can display "Direct Color DMA" demos and emulates CRAM contention (aka CRAM dots). Despite this high accuracy, even the most demanding software runs at full speed on modest hardware like a 1.6GHz AMD E-350 laptop. In the future, I would like to port it to the ARM architecture and optimize it further to run on systems as modest as the original Raspberry Pi.

Genesis Plus GX is an open-source Sega 8/16 bit emulator focused on accuracy and portability. Initially ported and developped on Gamecube / Wii consoles through libogc / devkitPPC, this emulator is now available on many other platforms through various frontends such as: Retroarch (libretro) Bizhawk OpenEmu The source code, initially based on Genesis Plus 1.2a by Charles MacDonald has been heavily modified & enhanced, with respect to original goals and design, in order to improve emulation accuracy as well as adding support for new peripherals, cartridge or console hardware and many other exciting features. The result is that Genesis Plus GX is now more a continuation of the original project than a simple port, providing very accurate emulation and 100% compatibility with Genesis / Mega Drive, Sega/Mega CD, Master System, Game Gear & SG-1000 released software (including all unlicensed or pirate known dumps), also emulating backwards compatibility modes when available.
