Using Mac OS X 10.10.4 and MacPorts, I was able to build Mednafen pretty easily using the following steps:Ĭopy the appropriate PS1 BIOS file(s) to ~/.mednafen/firmware/.

If you still want to experiment with the latest versions of Mednafen yourself and not wait for the OpenEmu team, keep reading. Luckily, it can be easily found in the experimental build of OpenEmu.īefore realizing the OpenEmu “experimental build” incorporates a working copy of Mednafen, I worked through all the steps to build and run Mednafen source code at the command line. Where PCSXR occasionally had missing audio, skipping during loading screens, and long loading pauses at a black screen for unexplained reasons, Mednafen delivered the genuine experience. It may not yet have all the upscaling functionality of the Windows PCSXR, but for Mac OS X it seems to be the best available PS1 experience. Over the weekend, I compared the latest Mednafen PlayStation emulation with the latest PCSXR, and Mednafen emulation is currently ahead.
