Preserving CD and DVD-based Console Games I had only ISO images, so I had to re-rip a game in cuesheet format in order to successfully add it to my OpenEmu game library.

OpenEmu’s “emulator core” for PS1 emulation is Mednafen, and this emulator requires all games be provided in cuesheet format.

The UI doesn’t make it clear that it has done anything with the files, but the lack of warning is your indicator that they have been accepted.

Scph5502.bin (EU) (sha1 sum: f6bc2d1f5eb6593de7d089c425ac681d6fffd3f0) … for me, this file was SCPH5552.bin, and had to be renamed.Īfter renaming these BIOS images, it was possible to drag them into OpenEmu and have them be recognized as PS1 BIOS ROM image files. It turns out the filenames were also important, and that I had to rename the files I had to be the expected filenames: But, after I found a set of BIOS ROM images online, adding them this way still didn’t work. Searching around, I learned that you add the BIOS file(s) by dragging and dropping the *.bin files (BIOS ROM images) like you would a game ROM.

The UI does nothing to explain how to provide the PlayStation BIOS file.

I tested out PlayStation support, and ran into a few obstacles before getting things to work. The experimental build version adds support for: The official release version of OpenEmu supports: Wow, it’s actually better than PCSX-Reloaded! Over the weekend I tried out the experimental version’s Playstation 1 emulation. In my last post about OpenEmu I mentioned the “experimental” build that adds support for many more systems than the official release of the program. With the game I was testing, an SBI file should not have been required, so I tried renaming an SBI file for some other game just to shut it up, and this seems to have worked. If a game does need an SBI file (because it was published as a LibCrypted disc), the SBI file can be downloaded from PSXDB Redump (link “SBI subchannels” on protected disc page). SBI file, even for games that should not need one. See my previous post on the cuesheet format and how to re-rip a game in that format or add a CUE file to an existing raw disc image.Īpparently, Mednafen also wants an.

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.
