Controls
Boots a homebrew demo cartridge — a full-screen diagonal rainbow of the Master System palette. Arrow keys = D-pad; X = button 1, Z = button 2; Enter = Pause. Use the on-screen gamepad on touch. Open the debugger to single-step the Z80 and set breakpoints. Click the screen first so it captures the keyboard.
