Gigatron TTL gtBASIC : Sprites, Blits, Parallax Scrolling and ADSR MIDI.
Fully coded in gtBASIC, it makes maximum use of the Gigatron's new instruction's and sys call's in ROMvX0.
Runs at 60Hz in Mode 2.
Four 9x10 animated Sprites.
Seven layers, (strips), of Parallax scrolling.
Three 30x24 animated Blits.
VSync playback of complex ADSR MIDI, (8bit audio).
Many cheats and hacks were used and abused to hit a sustained 60Hz.
