We would like to show you a description here but the site won’t allow us. OpenEmu will ask you to read the user guide before you try to add any disc-based games. Instead of adding these BIOS files into OpenEmu like a game ROM, you will have to drag them into /Library. You've imported a multi-disc game such as Chrono Cross in your library via drag and dropping the cue sheets Chrono Cross (USA) (Disc 1).cue and Chrono Cross (USA) (Disc 2).cue. Now create a.m3u file by opening up your favorite plain-text editor and copy and pasting the filenames of your cue sheets, one per line appearing as.

Over the weekend, I compared the latest Mednafen PlayStation emulation with the latest PCSXR, and Mednafen emulation is currently ahead. 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. 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. Luckily, it can be easily found in the experimental build of OpenEmu.

Before 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. If you still want to experiment with the latest versions of Mednafen yourself and not wait for the OpenEmu team, keep reading.

Building Mednafen from source:

Using Mac OS X 10.10.4 and MacPorts, I was able to build Mednafen pretty easily using the following steps:

sudo port install libsndfile

[after having extracted the Mednafen source archive and changed into the extracted directory]
./configure
make

Providing PS1 BIOS images to Mednafen:

Copy the appropriate PS1 BIOS file(s) to ~/.mednafen/firmware/ . For more on my difficulty with finding the correct files for this, see my previous post.

PS1 ROMs, Cuesheet, and Copy Protection Files required by Mednafen:

Unlike other PS1 emulators, Mednafen requires the cuesheet format for its ROMs. 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.

Apparently, Mednafen also wants an .SBI file, even for games that should not need one. 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). http://redump.org/disc/28260/ 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.

Running PS1 ROMs with Mednafen:

Openemu Multi Disc Games Bleemsync

It's necessary to find an optical drive capable of reading the CDs used as PlayStation games. It's also necessary to get OpenEmu (free) and set it up to play PlayStation games. This may require finding its appropriate BIOS files (check its settings). Otherwise, finding CD images for games which you own online is possible and left as a risk for the reader to take.

1. For OpenEmu to read and use a PlayStation game, it must exist as a file on the computer. If you have a set of BIN/CUE files, skip to step two.
   1. The entirety of the CD's binary data must be ripped to a binary file. Use a command like 'dd if=/dev/disk2 of='~/Downloads/Final Fantasy VII (USA) (Disc 1).bin' bs=2048 conv=sync,notrunc'.
      • (Here, '/dev/disk2' refers to a specific device on my computer. Open the Disk Utility on yours, find your optical drive, and find out what it's called. If it's 'disk3', use '/dev/disk3' instead. If you don't have an optical drive, this is a non-starter, of course.)
   2. For each binary file, then create a new empty text file with the same name, ending in '.cue' instead of '.bin'—for example, 'Final Fantasy VII (USA) (Disc 1).cue'. This will be a simple text file that describes the binary file as containing all raw binary information. Its contents should refer to the name of the binary file you just made, but otherwise, it should match the example given below exactly. Fill that in. Save and close the file in the same directory as the binary file.
   3. Repeat as necessary for other discs, remembering to reflect each disc number in the filename.
2. After creating all the BIN/CUE file pairs, create an M3U playlist listing all the cuesheet files (ending in '.cue') in order. This is a simple text file that ends in '.m3u' instead of '.txt'. See the example M3U file below.
3. With all files in the same directory, drag the M3U file into OpenEmu and allow it to copy it into its library. It should copy the playlist file, cuesheet, and binary contents.

Once the game is added to OpenEmu, it's possible to switch discs from the tool menu from within the game.
