Compo rules

Traditionally we'll have a graphic, music, demo, intro and wild compos for the Atari XL/XE, Commodore 64, ZX Spectrum and Amstrad CPC.

Entries can be sent to vasco@atari8.info, the deadline is the 10th of July, 2021, at 12:00 PM but it'd be easier for us if you could send it earlier. You'll get an e-mail to confirm we got your entry.

We accept remote entries.

Visitors and people with supporter tickets can vote.

We expect prizes for the winners!

  • General rules:
    • entries may not have been released or made public before,
    • at least three entries from at least two authors are required for the compo to go ahead,
    • if that's not the case, we reserve the right to merge the compos (however we'll let people know what compo particular entry was originally submitted to),
    • only original entries can be submitted to the music and graphic compos, no covers, no remixes, no mash-ups,
    • music and graphics entries should be submitted in one of the popular formats (or as an executable file, but only if you really need to!), more details below,
    • whenever it's possible, the compos will be anonymized, so should be your graphic/music entry,
    • playback time: up to 3 minutes,
    • entries should come with a .txt file including at least a name of the entry, compo this entry is submitted to and the author(s),
    • entries that don't meet the above-mentioned criteria may end up in a wild compo,
    • by submitting your entry you declare its freeware status.

  • Not so general rules:
    • Atari XL/XE:
      • entries using the extended memory should allow to choose the bank - it can be done by using a bank selector, additional config file or even by an extra block containing bank numbers (this block wont count against the file size in any size limited compos),
      • illegal 6502 instructions are... illegal,
      • Atari has a brilliant architecture that allows all sort of different expansions and extensions - submitting entries that won't work with them is against the rule.
