Deflemask Game Boy Engine (DGB)

Custom Deflemask .vgm based music playback engine for the Nintendo Game Boy. Now the official Deflemask ROM exporter as of Deflemask v1.0.3.

this engine only works with Deflemask generated .vgms and is not intended for other .vgms

supports EExx event commands from Delfemask and uses proper engine timings instead of .vgm update timings. Converter converts .vgm to either .gbs, .bin or .gb.

"High on time efficiency, low on space efficiency."

Formerly known as Deflemask GBVGM (DMGBVGM)
