// MSXgl example (multi-song lVGM): embeds two tracks and switches between them
|
|
// with SPACE. Built from two .lvgm files exported by the MSX MML Music Generator.
|
|
// Make the headers with: node tools/bin2c.mjs a.lvgm music1_lvgm.h g_Music1
|
|
// node tools/bin2c.mjs b.lvgm music2_lvgm.h g_Music2
|
|
//
|
|
// Build (from MSXgl/projects/samples/): bash build.sh s_mymusic_multi
|
|
// Run: openmsx -machine C-BIOS_MSX2+ -ext fmpac -cart out/s_mymusic_multi.rom
|
|
// (-ext fmpac is needed for any MSX-Music/FM track)
