Some example historical formats are mdf, nrg, img, iso and bin. Different formats took hold for short periods depending n their features set. If you have been around from the late 90s or have grabbed dumps from around that time you will be aware of how many different disc image formats there are. NAOMI) and a format was also needed to capture these. Beyond that some arcade hardware systems also began shipping with interchangeable discs (e.g. The format was originally developed to image later 200x arcade machines that had begun shipping with internal hard drives. New ROMs that don't have some of these problems and are playable with current MAME.Compressed Hunks of Data Manager IntroductionДЄ (C)ompressed (H)unks of (D)ata file or CHD for short is a standard format developed by the MAME project for storing hunks of data. There are also ROM management tools that may be able to reorganise ROMs to create I find the best solution is to put those problematic ROMs to one side and obtain some better non-split unmerged ROMs for the same game from somewhere else. The ability to play the games is just a nice side effect.' Providing backwardsД¬ompatibility with older ROMs isn't a top priority and this is complicated by theДЇact that IP issues mean that MAME cannot be supplied by the developers with ROMs.ДЄs someone else once said: 'MAME's primary goal is preservation.

If you've renamed the files, or they downloaded with the wrong names, you'll need to fix them. Note that MAME is very picky about ROM file names - they must match exactly what MAME expects them to be. NeoGeo games (Like King of Fighters '97) require neogeo.zip in your roms folder, but it seems like you've done that already. There are rules about where this CHD file lives, you can read up on this at the FAQ. CHD file is required in addition to the ROM. Files you find on ROM sites are a bit more suspect.ДЇor some games (like Street Fighter 3 Third Strike), a.
