This makes it 4 to 5 times faster than before, and the libretro port is probably now the best performing Sharp X68000 emulator you can get for various cheap or old devices. Running some tests on an old Samsung Galaxy S3, where we could barely emulate a 16MHz CPU before with PX68k stand-alone, we now achieve smooth results with a 66MHz setting. There is also a back end for the cyclone cpu on arm/android but surprisingly it didn’t give any speed enhancement and had more problems than the previously mentioned c68k.Īfter a common effort to fix various issues resulting from this change (thanks Retro-Wertz), it should now be at the same level of compatibility as the original emulator. As its development stopped some years ago, compatibility issues due to OS upgrades made its usage rather complicated.ĭeveloper R-Type decided to port it to RetroArch, replacing its old 32 bits based CPU emulation by a 64 bits one from Yabause core. Based on Win圆8k, targeting the PSP and ported to iOS and Android by its Japanese developer Hissorii, it was possibly the only X68000 emulator on those platforms. Outside Retroarch, PX68k was aimed to be fast enough for that usage. Its driver isn’t really the most advanced one and it is quite demanding, excluding many platforms such as smartphones. Until now the only way to run Sharp X68000 games in RetroArch was with MAME.

It was a powerful machine for its time and saw a great number of arcade ports, exclusive titles and doujin (indie) games developed for it, even years after the last model was launched in 1993. The Sharp X68000 was a home computer released exclusively in Japan in 1987. Developer r-type is the one who made the port Disclaimer: This article was written by Tatsuya79, who has also contributed many improvements to the X-68K core.
