opt_oki

The VGM OKIM6258 Optimizer scans streamed OKIM6258 data (from VGM logs of X68000 games) and optimizes them into "play sample" commands for the VGM "DAC Stream" system.

As of June 2022, the tool is stable and easy to use. However, the VGMs need to log the X68000 DMA commands. These commands are logged by XM6 VGM mod, 2021 release, and MAME VGM mod 0.236 and later.

Options

The tool does a slightly fuzzy sample detection by default. (It ignores the last 4 bytes of each PCM sample.) This fuzzy comparison can be disabled using -nofuzz.

The tool will dump all PCM samples if you add the -dump parameter.

If you don't specify an output VGM filename, opt_oki creates one by adding "_optimized" to the input filename.
