RomLister (Windows app, not needed if you decide to use the pre-compiled batch files) Two AHK scripts from this guide (modified from Tatsuya79’s originals) Either way, you’ll end up with nicely curated, per-genre MAME playlists. If that’s too much hassle, see if you like the ready-made genre groupings I came up with and just implement those, via either the supplied RomLister search strings or, even faster, the optional, pre-compiled batch files linked in Step 1. While the results are good and the process as streamlined as currently possible (?), it will still take some real time if you want to get your hands dirty and divvy up MAME’s 100+ genres into your own custom-sorted playlists (Step 2, below). Here’s a video showing the playlists in action: It’ll make everything look great in RetroArch and also save disk space, by only copying files you need. This guide, utilizing RomLister and two modified AHK scripts, will help you whittle down MAME’s romset, split it into genres, get the appropriate ROMs copied into genre subfolders, and automatically generate playlist files that have human-readable game titles and two types of pretty thumbnail images. That’s exactly the case with MAME and its massive 36,000+ file arcade romset. But it’s difficult to generate playlists when RetroArch doesn’t supply a content database (.rdb) file for a given library. RetroArch playlists let you find your content quickly without snooping through folders.
