Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
- Turbo mode executes a batch of instructions per frame, lifting the 1000 instructions per second ceiling so interactive programs stay responsive.
- New BIOS services: INT 16h keyboard reads with scan codes and INT 1Ah timer ticks, plus arrow keys and DOS extended keys in the console.
- Float the registers, memory, console or log panel in a movable, resizable window; maximize it, minimize it to a bubble, and the layout is remembered.
- The console is redrawn on a single canvas that fits the 80x25 grid to any screen, with pinch zoom and an on-screen D-pad in character mode.
- Assembler and runtime errors can now be copied. Fixes for memory displacement, label addresses and NASM-style res* labels.
- The 8086 model viewer now supports panning with two fingers, a right-drag, or an Option/Shift drag.
