Sony PlayStation

Runs homebrew MIPS demos on a from-scratch R3000A (MIPS I) interpreter — the PlayStation's main CPU. The default "boot" demo draws an animated colour field. Pick the "Gamepad test" demo and use the D-pad + face buttons (arrow keys move the box; K = Cross, L = Circle, I = Triangle, J = Square; Q/A = L1/L2, E/D = R1/R2; Enter = Start, Shift = Select), or the on-screen pad on touch. Open the debugger to read the live R3000A registers (r0-r31, PC, HI, LO) and memory, single-step one instruction, disassemble MIPS, and set execution breakpoints and memory watchpoints. Click the screen first so it captures the keyboard.
