Note that in FinalBurn Alpha, CHD files are often called “IMG” files. Once these files are removed from a romset, you can cut the file size significantly (by about 10GB for the romset I used in the video above). I usually keep only Killer Instinct and NFL Blitz. Personally, I go through each of these and delete all the CHDs of games that I don’t intend to play. Your first step when reducing a downloaded romset is to remove unnecessary CHD (“Compressed Hunks of Data”) files, which are data files used for CD-based arcade games like Killer Instinct, NFL Blitz, Area 51, and BeatMania. For example, the MAME 2003-Plus romset, which is what I used in the video above, totaled 34GB.

Just bear in mind that full non-merged romsets will initially be very large.

zip files will each contain all of the necessary parent and BIOS sets, we won’t have to worry about whether removing individual roms from the package will cause other games to not work. For example, in a Split set pacman.zip (a clone), will not work without puckman.zip (its parent).įor this guide, you will want to use a full non-merged romset. In some cases the parent is not the most popular or best working version of the game, however.

Split: Some romsets that are considered clones, translations, or bootlegs also require a “parent” romset to run.

The only exceptions are games which use BIOS ROMs, which are formatted as ‘Split’ and must be kept in the same folder as the game romset which uses it.

Non-merged ROM: All romsets can be used standalone because each zip contains all the files needed to run that game, including any files from ‘parent romsets’.

Full Non-merged: All romsets can be used standalone because each zip contains all the files needed to run that game, including any ROMs from ‘parent’ ROM sets and BIOS sets.

In addition to having a version number, arcade ROMs can be formatted four ways: CHD files should be copied to subfolders within the folder where the MAME ROM zips have been installed.

CHD: Some MAME games require data from an internal hard drive, CD-ROM, laserdisk, or other media in order to be emulated - those forms of media are packaged as CHD files.The path where these samples should be copied varies from emulator to emulator.

Sample: Some games require an additional zip file with recorded sounds or music in order for audio to work correctly.

For example, MAME 0.37b5 ROMs are required by the MAME 2000 emulator, but will not work correctly with the MAME 2010 emulator, which requires MAME 0.139 ROMs.

ROM version or romset version: Each version of an arcade emulator must be used with ROMs that have the same exact version number.

That is why some resources refer to an individual arcade game as a ROM (like people use to describe a zipped game cartridge ROM) while other resources refer to an individual game as a ROM set or romset.

ROM, ROM set, and romset: Arcade games are packaged as zip files, most of which are composed of more than one individual ‘ROM’ file.

These definitions are taken from RetroArch’s “ Getting Started with Arcade Emulation” guide. The world of arcade games can be confusing, so let’s set some definitions now. I haven't yet tried SDL MAME.Most everything you’ll want to know is covered in the video above, but here is a written guide. The upshot is that I've gone back to MAME OSX. I found that more of my roms failed to play under OpenEmu than MAME OSX, after making the preferences correction identified by vickerrrs in an earlier post. In fairness, most games have only one joystick and fewer than six buttons, so OpenEmu should be fine. I tried crazy climber, which has two joysticks in the arcade version, and it just can't be played because the controls can't be mapped under OpenEmu. That works well enough for simple games like pac man or galaxian, which use a joystick and maybe a button or two, but arcade games that have complex controls might not be playable on OpenEmu. The mappings you choose apply to all games. OpenEmu only allows you to map the following: left, right, up, down, and buttons 1 through 6.

MAME OSX allows you to map each of the arcade game's controls to your own controller.

The area where OpenEmu fails to match MAME OSX is in the control mappings. No more using the tab key to get to the game control mappings as in MAME OSX. OpenEmu starts right up and has a fully graphical interface. (The regular OpenEmu build appears to emulate home consoles only.) OpenEmu even downloaded the mame "core" when it determined the core was not installed.

Make sure you install the "Experimental" build or you will lack support for mame.

OpenEmu installs seamlessly - just download it and place the app in your Applications folder. I tried OpenEmu as suggested by vickerrrs.
