This jam is now over. It ran from 2020-10-01 07:00:00 to 2020-11-01 07:00:00. View 27 entries
You have a hex keypad for input, 64x32 pixels (or 128x64 with SCHIP), 3.5kb of RAM and code space (64kb with XO-CHIP), and two colors (or up to 4 with XO-CHIP). Embrace these creative constraints, and make the most of them!
The Octo IDE allows you to write CHIP-8 games in a beginner-friendly low-level language, and even export standalone HTML builds of your game to share here on Itch. If you've used Octo before, you might be interested in a summary of the latest improvements.
|Octo Source Code||Output|
: main i := ball loop sprite v0 v1 7 v0 += 3 v1 += 5 again : ball 0x38 0x74 0xFA 0xFE 0xFE 0x7C 0x38
Using other tools or homespun CHIP-8 emulators is also fair game. If you're interested in making games that will run on historical hardware, like the COSMAC VIP or the HP-48 calculator, reach out on this jam's forum for tips!
