Descargar Genesis Plus GX 1.7.4






NTRODUCTION

This is an enhanced port of Genesis Plus, an open-source & portable Sega Mega Drive / Genesis emulator, now also emulating SG-1000, Master System, Game Gear and Sega/Mega CD on Gamecube and Wii, through libogc & devkitPPC.

The source code, originally based on Genesis Plus 1.3 by Charles MacDonald, has been heavily modified, with respect to initial goals and design, in order to improve accuracy of emulation, implementing new features and adding support for extra peripherals, cartridge & system hardwares.

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 game libraries (including all unlicensed or pirate known dumps), also emulating backwards compatibility modes when available.
Last but not least, it comes with plenty of exciting features and options that have nothing to envy to your most favorite PC emulators and makes this emulator the most faithful experience for any Sega 8/16-bit fans.

* improved SUB & MAIN-CPU synchronization ("Dracula Unleashed" freeze when using US Model 2 BIOS)
* improved CPU polling detection
* improved CDD emulation & added CD drive access time for SEEK command ("Panic!/Switch" intro missing scene)
