But it is based on the newer MT-32 revision, and therefore, games which rely on the bugs of the old MT-32 won't sound right on a CM-32L. The CM-32L supports sound effects in addition to MT-32 music, though this is only relevant for games specifically designed to take advantage of the CM-32L. So you actually do want the buggy MT-32 ROM. The downsides of the bugs are of no consequence when emulating an MT-32. Later ROM revisions fix these bugs, but said games won't sound correct using them. The first revision of the MT-32 contains some bugs, but an unknown number of games actually rely on these bugs to produce the correct sound. SHA1 hash is b083518fffb7f66b03c23b7eb4f868e62dc5a987 if you're savvy.Īn explanation on what's going on here. Anything with '1987' or '1.07' in the name is fine. For instance, 'MT32_CONTROL.v1.07.ROM.' For the MT32_CONTROL.ROM file, you will want the oldest revision possible. The 'CONTROL' roms sometimes come in multiple revisions and may have a longer filename to reflect this. There are four ROM files relevant to you:

Many ScummVM games were composed for the MT-32 or CM-32L sound modules, and ScummVM can emulate both, but you will need to acquire ROMs, which are in a state of legal limbo. Otherwise, the stable release version is all you need. Don't get them mixed up, and stick with the stable release version for playing games supported by it. If you're interested in bleeding edge support, it may be worth it to have two side-by-side ScummVMs one stable release version, and one daily build version. Downloading and installing should be straightforward. Sometimes GOG doesn't even bundle ScummVM when they could.You can enable the MT-32 emulator, which usually doesn't work in preconfigured ScummVMs.You can set global settings across all games.Often the bundled ScummVM in GOG titles is outdated. You can keep ScummVM up to date with the latest version for better features and better accuracy.Setting up your own copy of ScummVM is more work, but gives you some advantages. Setting up a ScummVM (the power user way) Skip to the next section to see what all those options do. That's it! Now you can poke around in the ScummVM options. With the game highlighted, click Edit Game. Launch the game, press CTRL+F5 to open the ScummVM main menu. GOG's copy of Beneath a Steel Sky is preconfigured with ScummVM, and works as an example. Furthemore, this method doesn't allow using ScummVM's MT-32 emulator, and although it's possible to enable it on a preconfigured ScummVM, this requires enough work that you might as well just follow the power user guide. And a small number of games don't allow this method. This only works with GOG titles that are bundled with ScummVM. Using a preconfigured ScummVM (the lazy way) 2 Setting up a ScummVM (the power user way).1 Using a preconfigured ScummVM (the lazy way).I will show two ways to invoke ScummVM for configuration the lazy way, and the power user way. What's even worse is when they bundle with DOSBox, configure the music incorrectly, and include no easy way of fixing it. GOG does not always configure their ScummVM settings optimally, especially when it comes to music settings. Several of GOG's titles come bundled with ScummVM, though many more don't even though ScummVM supports those games. Numerous other developers' games have ScummVM support, but not as comprehensively. Lesser known developers with fairly comprehensive ScummVM support include Adventuresoft, Coktel Vision, and Humongous Entertainment. More recently, Sierra games have been a major focus, and stand to gain much in the way of enhancement. These were the first games to be supported, and the name 'ScummVM' comes from LucasArts' SCUMM engine. LucasArts adventures are the biggest focus of ScummVM. ScummVM is an emulator-like program that runs a number of old computer games, mostly adventure titles, on modern operating systems, often with bug fixes and enhancements.
