CLASSIC EMULATOR CODE AT THE

Macintosh.js emulates Mac OS 8.1 running on a Quadra 900, with 256 MB of memory. The most advanced of these emulator programs is SheepShaver. Versions 6 through 9) can only be run through software that emulates Macintosh hardware from the 1980s and 1990s.

RetroArch is the application for the user, and individualВ emulators can be adaptedВ or abstracted away by the LibRetro interface, turning them into вЂњcores.вЂќ This is much the same way that OpenEmu works, but RetroArchВ is portable: it works not only on MacOS, but on Windows and Linux and even smartphones and jailbroken game consoles. Their goal is to run basically any emulatorВ onВ any machine, using an underlying middlewareВ API they call LibRetro. (Technically we have to call it a front-end, because itвЂ™s just providing a unifiedВ interface to a collection of already-existing emulators).RetroArch is the relative newcomer on the scene. ItвЂ™s a single player (and local multiplayer) multi-system emulatorВ front-end. When you addВ a game to your library, the box art thumbnail just shows up automatically, no further action required on the userвЂ™s behalf.OpenEmu does not apparently support emulator tweaking (no super-hi-res PS1 emulation or widescreen hacks), nor does it support netplay, or streaming.

The reason this UI makes sense for RetroArch is that it can be entirely game-controller-driven. If it works donвЂ™t fix it, I guess. Close to 100, although many of those are variations (several choices of GBA emulator, several choices of PS1 emulator, etc.)The RetroArch default interface is an homage to the Sony PS3 and PSPвЂ™s вЂњcross-media barвЂќ (also known as the XMB) design. Compared to OpenEmu, RetroArch supports many moreВ emulator cores. It also allows for far more configurability than OpenEmu, for better or worse.

If you ask it to download something in the background, it will get to 99% and then halt all emulation for a few seconds before reaching 100%. You may get stuck in a menu tree where you canвЂ™t go back without closing RetroArch. I had major problems and inconsistent results launching Playstation 1 games.В Loading a gameВ before you load its corresponding core may or may not succeed. I experienced multiple bugs running it on MacOS: using the window frame controls to go full-screen corrupted the picture and I had to use the in-app setting to change it to full screen, instead. Well, I did have to hit the PS home button.The rest of the UI is not so painless though. I didnвЂ™t need to spend any time at all in RetroArch configuring my PS3 controller, I just plugged it in and that was it.

Unlike with OpenEmu, itвЂ™s unclear if there is any kind of automatic updating for these cores or if thatвЂ™s a manual step also.All of these sharp edges aside, RetroArch is an amazing project. You have to flip through its menus and download each individual one that you are interested in. Likewise, RetroArch doesnвЂ™t have any emulation cores when you first run it. If you accidentally hit the ESC key, it instantly closes RetroArch.В If you run RetroArch, you basically donвЂ™t want to use it without a controller.If you want box art thumbnails, you must direct RetroArch to download an entire set for a given system, regardless of how many of those games you actually own.

Luckily, it can be easily found in the experimental build of OpenEmu.Before 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. Either way, the future of emulation is looking bright.Over the weekend, I compared the latest Mednafen PlayStation emulation with the latest PCSXR, and Mednafen emulation is currently ahead. It also has some unique advantages, including: netplay (including spectating), achievements (via RetroAchievements.org), recording and streaming.Either OpenEmu will expand its feature set to compete with RetroArch, or RetroArch willВ improve the usability of its UI.

Over the weekend I tried out the experimental versionвЂ™s Playstation 1 emulation. В 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.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. 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.Apparently, MednafenВ also wants an. 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.

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. It turns out the filenames were also important, and that I had to rename the files I had to be the expected filenames:Scph5500.bin (JP) (sha1 sum:В b05def971d8ec59f346f2d9ac21fb742e3eb6917) вЂ¦matched whatВ I hadВ in the download pack I found.Scph5501.bin (NA) (sha1 sum:В 0555c6fae8906f3f09baf5988f00e55f88e9f30b) вЂ¦ for me, this file was SCPH7003.BIN, and had to be renamed.Scph5502.bin (EU) (sha1 sum: f6bc2d1f5eb6593de7d089c425ac681d6fffd3f0) вЂ¦ for me, this file was SCPH5552.bin, and had to be renamed.After renaming these BIOS images, it was possible to drag them into OpenEmu and have them be recognized as PS1 BIOS ROM image files. 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.

Cue, rather than a single. 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. 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.Preserving CD and DVD-based ConsoleВ GamesPreserving CD and DVD-based Console Games (Pt.В 2)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.
