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 usedВ inВ the early games of the PS1/SaturnВ generation. You can rip all of their data, but without metadata to indicate the track boundaries, it seems that multi-track disc imagesВ canвЂ™t be properly handledВ (?). I mentioned in my first post in this series that many old games use вЂњmixed-mode discsвЂќ (audio and data as separate tracks). Well thereвЂ™s actually a case where cdrdao is needed, and that is when your emulator wants game images in the вЂњ cuesheetвЂќ format (a pair of files with the file extensions.

In a previous post, I mentioned that two command-line utilities for making optical discВ images on Mac OS X were dd and cdrdao, but I recommended dd because it was simpler to use. Preserving CD and DVD-based Console Games (Pt.В 2) Preserving CD and DVD-based ConsoleВ 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. OpenEmuвЂ™sВ вЂњemulator coreвЂќ for PS1 emulation is Mednafen, and this emulator requires all games be provided in cuesheet format.The UI doesnвЂ™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) вЂ¦ for me, this file was SCPH5552.bin, and had to be renamed.ДЄfter 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 didnвЂ™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 provideВ the PlayStation BIOS file.

I tested out PlayStation support, and ran into a few obstaclesВ before getting things to work. The experimental build version adds support for: The official release version of OpenEmu supports: Wow, itвЂ™s actually better than PCSX-Reloaded! Over the weekend I tried out the experimental versionвЂ™s Playstation 1 emulation. In my last post about OpenEmuВ I mentioned theВ вЂњexperimentalвЂќ 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 renamingВ anВ 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 вЂњSBI subchannelsвЂќ on protected disc page). SBI file, even for games that shouldВ not need one.

See my previous post on the cuesheet format and how to re-ripВ a game in that format or add a CUE file to an existing raw disc image.ДЄpparently, MednafenВ also wants an. Unlike other PS1 emulators, Mednafen requires the cuesheet format for its ROMs. PS1 ROMs, Cuesheet, and Copy Protection Files required by Mednafen: For more on my difficulty with finding the correct files for this, see my previous post. Using Mac OS X 10.10.4 and MacPorts, I was able to build Mednafen pretty easily usingВ the following steps:Д¬opy the appropriate PS1 BIOS file(s) to ~/.mednafen/firmware/. If you still want to experiment with the latest versionsВ of Mednafen yourself and not wait for the OpenEmu team, keep reading.

Luckily, it can be easily found in the experimental build of OpenEmu.Д«efore realizing the OpenEmu вЂњexperimental buildвЂќ 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.
