The AdLib emulator setting offers MAME, DOSBox and Nuked emulation, with MAME being the least accurate and using the least CPU power, and Nuked being the most accurate and also using the most CPU power - DOSBox is somewhere in between. The SoundBlaster Pro 2 and 16 had an OP元 chip. The SoundBlaster Pro 1 had two OPL2 chips The original AdLib and SoundBlaster card had one OPL2 chip. ScummVM emulates a few different AdLib configurations, and selects the most appropriate for the game:
While some games do store their audio data using a MIDI-derived format, this is converted by the game to work with the AdLib chip. They instead have a chip that produces sound through FM synthesis. For example, changing the General MIDI settings will not have any effect on a game that only has CD audio.ĪdLib devices do not use MIDI. Not all settings are applicable to all games. If Preferred device or Music device is set to either an MT-32 device or a GM device, ScummVM will use that device and ignore the devices chosen on the MT-32 and MIDI tabs. If Preferred device or Music device is set to and ScummVM chooses either an MT-32 or General MIDI device automatically, the settings on the MT-32 or MIDI tabs also apply, and the devices selected on these tabs are the ones that will be used. When set to, ScummVM will automatically choose the most appropriate option for the played game. This device can be an emulated sound device or a software synthesizer, or an actual hardware device such as a soundcard or a hardware MIDI synthesizer. The Preferred device in the global settings Audio tab, or the Music device in the game-specific settings Audio tab, specifies the device that ScummVM uses to output audio. How do the audio settings work together? ¶
