Releases: derpyder/Arcade-MajorHavoc_MiSTer
Major Havoc v1.1
Full-screen display update for the Major Havoc MiSTer core.
What's new in v1.1
- Full-height image. The Vector Scale Fill mode now scales to ×1.3125, centered, so Major Havoc fills the screen instead of sitting in a small central box. Confirmed on DE10-Nano hardware.
- Fixed the coord-map width bug that had garbled an earlier full-screen attempt into tiled "quadrants." The centering is now scale-locked and width-safe, verified in simulation against the real RTL (
sim/fb/tb_coord.sv). - If a scene ever clips on your display, drop Vector Scale → Full (1×) in the OSD.
Everything from v1.0 carries over: dual-6502 + color AVG, quad-POKEY audio, the roller via the left analog stick / a USB spinner / a USB mouse, fire / shield / coin, authentic ~10 MHz speed, and the tunable phosphor-persistence present-gate.
⚠️ ROMs are NOT included. You must supplymhavoc.zip(MAMEmhavoc) ingames/mame/.

Known limitation: hi-score persistence (EAROM) is not yet implemented.
Major Havoc v1.0
Atari's 1983 dual-CPU color-vector game on MiSTer FPGA, grafted onto Videodr0me's Star Wars vector chassis.
Playable on DE10-Nano hardware: the maze, reactor and space sequences render; quad-POKEY audio; the roller works via the left analog stick, a USB spinner, or a USB mouse; fire / shield / coin. The game runs at authentic speed (~10 MHz, clock-enable-gated on the 12.096 MHz chassis), and the display is stabilized by a phosphor-persistence present-gate (tunable via the OSD Persistence knob).
⚠️ ROMs are NOT included. You must supplymhavoc.zip(MAMEmhavoc) ingames/mame/.
