DASH64 PRO
A Geometry Dash demake — one button, nine different meanings.
A rhythm game cut down to fit a C64. Fourteen tracks, each with its own tune, and the obstacles sit on the beat — at 150 BPM one beat is exactly ten columns:
- Nine modes, one button: the cube jumps, the ufo thrusts, the ball flips gravity, the wave climbs while you hold, the spider is on the other surface at once, the robot rises as long as you hold, the mini is half height, and dual drives two players together.
- The shape changes with the mode — a saucer, a rocket, a triangle pointing where you are going. You know which rule is in force without reading anything.
- Rings and pads: one gives you a fresh arc in mid-air, the other throws you the moment you touch it.
- Three coins per track, a practice mode with checkpoints, and an attract mode that plays itself.
- The GOKALP track is not ours: it is “Commander 64”, built in the real Geometry Dash by Gokalp, age 12, and converted from the game’s own data — all 688 objects read, with section boundaries landing within 1% of the original.
What it needs
| Machine | PAL Commodore 64. Everything is built around the 19,656-cycle PAL frame; NTSC is not supported. |
|---|---|
| Sound | SID 6581 or 8580. The sound leans on pulse-width modulation rather than the filter, and that is the same on every chip. |
| Controls | Joystick in port 2, or the keyboard. |
| Size | One file, 47 KB. After it loads, the drive is never touched again. |
| Version | PRO v1.4 |
Download
The .d64 is a disk image: copy it to an SD card device, or mount it in an emulator. The .prg loads directly. Either way it is LOAD"…",8,1 then RUN. The zip has both, plus the release notes and screenshots.
Progress is nine characters. Press E on the menu to type it, and it carries every coin you have collected. It is a code rather than a disk save because the game might be running from an SD card, a real 1541 or a tape, and KERNAL SAVE fails silently on some of them. A save that disappears without saying so is worse than no save at all.
