Oldskool Competitions

Supported platforms are anything with a CPU that has a 16 bit or smaller data bus (C64, Amiga ECS, VIC20, Atari XL, Atari ST, NES, SNES, Master System, Mega Drive, ZX Spectrum...).
Please contact us beforehand for any platform that does not produce a VGA or PAL signal so we can plan to record your production properly. Ideally bring a recording yourself in this case - providing your own recording does not mean we don't need to see the real hardware.
For C64: Please state which SID chip to use (6581/8580). This information will be displayed on the info slides for your production.
Please state if your entry requires any user interaction (pressing space at the end of parts etc.).
The entry has to be delivered as a disk- or cartridge file (strongly preferred). Don't have an image? Physical media are still allowed, don't worry: FIRST create an entry number, THEN deliver your media to the infodesk - it's that easy.
You must deliver proof that your entry works on real hardware (i.e. bring the hardware with you and show the organizers).

Maximum size is 1 standard medium for your platform. For example
- 1 disk (both sides on single-side media) on VIC20, C64, Atari ST
- 1 cartridge image for NES
- 1 roll of paper tape for your Data General NOVA System.
Maximum running time: 8 minutes (including loading/precalc, which won't be shown on the big screen).
No autostart or assembler jumps/SYS on systems with a BASIC interpreter.

Maximum size is 4096 bytes (16 blocks and 32 bytes on C64). The production must be a single file. (Noters are OK). If the minimum cartridge image for your platform is larger than 4096 bytes, only the first 4096 bytes of the cart may be used - bring a cartridge image as proof.
Maximum running time: 8 minutes (including loading/precalc, which won't be shown on the big screen).
No autostart or assembler jumps/SYS.
