Together Revision 2021 - on a sofa near you

Amiga

Amiga AGA

  • Technical Requirements:
    • The competition machine for AGA productions will be an A1200, 68060/66Mhz with 64MB RAM and OS 3.1 (original C= version), with latest AHI installed, latest phase5/DCE 68060.library and SetPatch v43.6.
    • PPC Amiga entries are accepted for the Wild Compo. We do have AmigaOS4/MorphOS hardware but please contact us in advance if you need them.
    • Entries which require Vampire/Apollo/other FPGA accelerators are accepted for the Wild Compo.
    • Assigns and installation scripts are forbidden. Going into the demo's directory and starting the main executable have to be the only necessary steps to watch the demo.
    • No other libraries or datatypes will be installed on the compo machine, only what's included in the original C= OS 3.1 release. Make sure your production does NOT depend on any OS 3.5, OS 3.9, OS 3.1.4, etc. specific features.
    • All custom libraries have to be delivered with the demo/intro; they have to reside in the demo/intro's directory and will count into the file size of your production.
    • Pressing either the right mouse button or ESC has to end the demo instantly.
    • The entry has to be delivered as single .lha, .lzx, .lzh, .zip or .tar.gz file.
    • All entries have to run in a "clean" environment, that is booting AmigaOS without startup sequence, running SetPatch and then the demo/intro executable.

Amiga ECS/OCS

  • Technical Requirements:
    • The competition machine for OCS/ECS productions will be a stock A500, with 512K chip and 512K slow RAM and Kickstart 1.3.
    • Additionally to the formats specified for AGA, .adf, .adz, and .dms files are also accepted.
    • Your intro still has to be a standalone, single file executable, on a DOS-readable disk image (we will copy the file to a different disk, no trickery please).
  • Before You Submit Your Entry:
    • Unless you try to do some really advanced OCS/ECS-only effects, we encourage everyone to at least try to make your entry also run on expanded Amigas, on faster CPUs, and on AGA chipset. Deliberately breaking compatibility is not cool. (We will still run your entry from the A500, of course.)
  • And finally:
    • For demos, it's allowed to boot from the disk, and doesn't need to be DOS-readable.

16:9 Recording Option

  • Annoyed by the thick black frame on screen around your Amiga entry? We can record your Amiga entry in a 16:9 format, so it will be full screen on the stream!
  • On the standard 320x256 PAL screen, only render into a 320x180 (16:9) area, positioned vertically to the middle.
  • If you setup your screen manually, use the following values: DIWSTRT,$5281; DIWSTOP,$06c1
  • Do not change the resolution or change the position of your render area during your entry.
  • Preferably set the border color to black outside this render area.
  • This option was mainly invented for AGA entries, but OCS/ECS is not excluded.
  • If you want this option, make sure to leave a note to the organizers in the party system when submitting your entry.
