DRO

The DRO format

DRO (DOSBox Raw OPL) is the "AdLib register event capture" format of DOSBOX. With this feature of DOSBOX, you can capture AdLib tunes from any DOS softwares.

My C64 player only supports version 2 (DOSBOX version 0.73 or newer is required!) of this format and there is no check for that: any file is treated as a DRO one, even if it's not, so you must be careful with this! Also currently it's a compile time option to include the DRO file, you cannot select one to play on your C64!

Currently IMF format is playable in a way that you have to convert it (on your PC, not C64) into DRO, which is (hopefully) playable then.

Please note, that only version 2 of this format is supported!
