This Soundfont is a fixed version of Micasddsa4000's Jummbox Soundfont. I, stgiga, fixed the pitch and mappings, and also added Zandro Reveille's OPL3 drums (TheFatMan is part of the equation, including OPL2 booster drums too) (also William B. Santos's YM2612 and Piconica (free basic waveform synth tool of sorts) drums were used to boost the range again, resulting in a drum range of drum note 22 to drum note 93) because Micas didn't use drums. It's really neat and retro!
