Schreckenstein-64 stands as an impressive homebrew Commodore 64 adaptation of the obscure Atari 800/XL title by Peter Finze, originally released in 1987 as a rare two-player competitive platformer.
Control one of two quirky characters—either the knight or the monster—in intense split-screen versus matches that demand split-second decisions. Navigate scrolling platforms filled with spikes, ladders, and moving hazards, using jumps, punches, and throwable projectiles to knock out your rival and score points by grabbing collectibles. The single-player mode pits you against a CPU opponent that now navigates levels reliably thanks to bugfixes addressing previous sticking issues, while two-player mode shines on real hardware or emulators with dual joysticks plugged into ports 1 and 2. Levels progress in difficulty with tighter layouts and faster enemy patterns, but sessions remain bite-sized, perfect for quick grudge matches.

This build accelerates packed datafile loading for snappier startups, introduces a pause function absent in the Atari original, and refines sound arbitration to prevent audio glitches during overlapping effects like jumps and hits. Graphics retain the original’s vibrant, parallax-scrolling backdrops and fluid sprite animations optimized for the C64’s VIC-II, running at a playable pace despite the hardware’s modest 1 MHz clock—slower than Atari’s but compensated by smart code tweaks.
Zzapped in the Butt Special Edition delivers a hilariously over-the-top vertical shooter for Commodore 64, channeling classic arcade invaders with absurd humor and relentless alien-blasting action.
Pilot a lone defender against waves of cheeky invaders descending from a massive mothership bent on planetary destruction. Dodge colorful projectiles while firing back with rapid shots and power-ups that supercharge your weapon into a devastating laser beam, clearing screens packed with erratic enemies and screen-wrapping surprises. Lives dwindle fast from collisions or sustained fire, but bonus stages and escalating patterns keep runs tense and replayable on real hardware or emulators like VICE.
Pixel art pops with garish 80s flair—bulbous aliens, fiery explosions, and scrolling backgrounds that fit snugly within C64’s multicolored limits. SID chip soundtrack blasts funky chiptunes and zany sound effects, from pew-pew lasers to comical butt-zap impacts, creating an earworm experience true to retro homebrew spirit.
Optimized for smooth 60Hz performance without slowdowns even in bullet-hell moments, this Special Edition expands the original 4KB compo entry with extra levels, polished controls, and cart-ready binaries. Supports joystick or keyboard input, ideal for quick sessions on C64 Forever or physical setups with your preferred router-forwarded emulation rig.
Math Test v1.0 by Andre4s (Team Tomato) brings a straightforward educational tool to the Commodore 64, targeting kids with customizable arithmetic drills in addition, subtraction, multiplication, and division.
Access a simple main menu to launch tests, tweak settings, view credits, or exit. Customize question count (default 20), select operators, set operand ranges (min/max values), toggle negative numbers, and adjust colors for text, borders, and backgrounds to suit preferences or reduce eye strain during longer sessions. Input answers via keyboard on real hardware or emulators, with immediate feedback on correctness.
Fills a niche for modern homebrew math trainers on legacy hardware, echoing 80s edusoft like Stickybear but with user control over parameters. Great for parents or retro enthusiasts teaching kids via authentic 8-bit interfaces—simple, effective, and free.
Caprica Defense by Peter Otto delivers a strategic space shooter for Commodore 64, inspired by Battlestar Galactica’s Cylon invasion of Caprica and human colonies, evolving Super Nova-style gameplay with map-based navigation and upgrade hunts.
Pilot a Colonial Viper defending against six mobile Cylon Basestars that roam a sector map, destroying Battlestars on contact—press M (when no foes nearby) to view and warp along clear paths to planets, the sun, or the relocating Battlestar for repairs. Collect super laser upgrades from celestial bodies (one per cycle, resets on Basestar respawn) to pierce Basestar shields, while dodging Raider swarms, vortex damage zones, and the Basestar’s own firepower in cockpit dogfights.
Symbols clarify threats: Viper icon for your position, planets/sun for laser pickups, Battlestar for docking (protected while you’re nearby), Cylon icons for Raiders/Basestars, and vortices to evade. Basestars demand sequential upgrades—defeat one, grab another laser elsewhere—creating cat-and-mouse pursuits across the star system, blending exploration with twitch shooting.
Cockpit view shifts to crisp vector-style starfields and sprite enemies with smooth scrolling, while the map overlays clean icons on a grid for strategic planning. Joystick handles precise movement and firing; runs fluidly at PAL/NTSC speeds on real C64s, VICE, or C64 Forever without hitches, downloadable as v1.1 .D64 for instant play.
This free 2025 release captures BSG’s desperate fleet defense vibe on 8-bit hardware, rewarding planning over button-mashing—ideal for retro fans seeking depth beyond pure arcades, alongside your emulation library of shooters and TND64 demos.
