About
Menace is the 1988 Psygnosis shooter that started DMA Design, the studio that later made Lemmings and Grand Theft Auto. Dave Jones wrote it and Tony Smith drew it. You fly through six worlds of the planet Draconia, each with its own guardian at the end, collecting weapon upgrades from the enemy waves on the way. Menace IIgs is rmprod's native 65816 port of it, released on itch.io on 29 October 2026, with the original artwork converted for Super Hi-Res, the scrolling and parallax, the HUD, the music, the sound effects and the boss announcement, the introduction, the world transitions and the ending.
It launches from the GS/OS Finder. Arrows or the numeric keypad move, including diagonals; Open Apple or Alt fires; A toggles autofire, J toggles the GS joystick, R restarts after game over and Esc returns to the Finder. On the menu, 1 is Rookie and 2 is Expert, which doubles the score. In Rookie, touching normal enemies is safe while terrain and bosses still kill you. The tested configuration is 8 MB of RAM with an accelerator at 7 MHz or faster; 14 MHz is preferred for smooth play. It does run at the stock 2.8 MHz, with lower smoothness and longer loading times.
The download is a single 24 MB 2IMG. It is a GS/OS 6 boot volume that comes up in the Finder with the MENACE icon, the 7.3 MB game plus five 2 MB world files, so it can be mounted on its own or copied onto an existing hard drive. This archive does not host it; get it from rmprod's itch.io page, where it is name your own price. rmprod has tagged the page with itch's AI disclosure for the code. Updates are planned from player feedback; when reporting a problem include your hardware or emulator, speed, world and controller.
