If you have MacPorts, the command is as follows: $ sudo port install cdrdaoīacking up a PS1 disc in cuesheet format, using cdrdaoįind and unmount the disc filesystem. Note that your binary image file has to be named consistently with what is in each CUE file.įirst, you need to install the “cdrdao” package from either MacPorts (recommended), Fink, or from source. It would fail with weird errors unless I provided the game in cuesheet format.Īlmost any cuesheet file can be found at . In fact, you can just download every cuesheet for a given system all at once, which is nice. Maybe it will preclude you from having to create your own, if you ripped your games as ISO.

I realized the need for cuesheet format when I tried to use the Mednafen emulator to play a Playstation 1 game I backed up in ISO format. Most 16-bit era CD games were this kind of disc, and sometimes it was used in the early games of the PS1/Saturn generation. You can rip all of their data, but without metadata to indicate the track boundaries, it seems that multi-track disc images can’t be properly handled (?).

I mentioned in my first post in this series that many old games use “mixed-mode discs” (audio and data as separate tracks). Well there’s actually a case where cdrdao is needed, and that is when your emulator wants game images in the “ cuesheet” format (a pair of files with the file extensions.

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.
