Motocross Maniacs has reached the ZX Spectrum 128K in a new unofficial conversion by kirby2000. Released on 16th October, the game adapts Konami’s Game Boy racer with eight courses, three difficulty settings and a split-screen mode for two players on the same computer.
The routes send riders over ramps, rocks, soft ground and overhead loops. Along the way, pickups supply more nitro, extra time and other upgrades. The developer also lists hidden jet power and miniature bikers among the conversion’s features.
Solo mode sets a qualifying time to beat before advancing to the next course. Racing against the computer adds another rider, although beating the qualifying time still decides progression. In two-player mode, the screen divides horizontally, with the first player above the second. The first rider across the finish wins.
The original Motocross Maniacs arrived on Game Boy in Japan in 1989, followed by US and European releases in 1990. Its side-on courses combined racing with jumps, obstacles and a supply of nitro boosts. Konami later followed it with Motocross Maniacs 2 on Game Boy Color and Motocross Maniacs Advance.
The Game Boy’s two-player mode required two linked handhelds, two cartridges and a Game Link cable. The Spectrum conversion instead puts both riders’ views on one display, with separate controls for each player.
Game Boy racing with Spectrum controls
On the handheld, the A button handled acceleration while B activated nitro. Directional input changed the bike’s position, including its angle during jumps. The original manual also described pickups for extending the time limit, improving top speed and helping the bike across rougher surfaces. Those racing and obstacle-course elements distinguish its format from a conventional circuit racer.
For the Spectrum version, the default keyboard layout gives player one Q and W to lean, E to accelerate and R for nitro. Player two uses U, I, O and P for the same actions. Keys are redefinable, and Enter pauses or resumes a race.
The game detects Kempston interfaces automatically and also supports Sinclair joysticks. With a joystick, left and right control leaning, up accelerates and fire activates nitro. Kempston controls the first player. Course records and customised key settings last for the current session rather than carrying over after restarting.
The release targets the Spectrum 128K, +2, +2A and +3, with AY music and sound effects. Emulator users need to select a compatible 128K machine. The package supplies TAP and TZX tape images, a bootable +3 disk image, SNA and Z80 snapshots, instructions and a printable cassette inlay. The combined download for all formats is listed at 7.2MB.
The complete release is available through kirby2000’s itch.io page.
