• The competition machine will be a Intel Core(tm)2 Duo E6400 (2,13GHz) with 1GB of RAM and an ATI Radeon X1900 XTX (512MB VRAM).
• We will use Windows XP with Service Pack 2, DirectX 9.0c (December 2006) and Catalyst 7.3 drivers. We will NOT install any drivers or virtual machines to provide or improve DOS compatibility, don't expect anything more than Mode13h and nosound if you really dare to submit a DOS demo.
• No Linux entries. We had very few Linux entries when we accepted them, and since we usually get brand-new compo machines, there are usually no stable drivers available. We don't have time on the party to tweak around with experimental software, and since we can't guarantee smooth operation, we don't support it.
• Java/.NET entries are allowed in the Demo compo, but not in the intro compos. (Please contact us in advance if you plan to submit such a demo)
• You will have to state which graphics hardware your demo/intro is compatible to on the submission form ("Compatibility Chart"). Please do so truthfully.
• Pressing either ESC or Alt-F4 has to end the demo instantly.
• The entry has to be delivered as single .zip or .rar file.
• Maximum resolution is 1024x768 pixels.
• If your demo has a configuration dialog, either provide sensible defaults for the compo or specify the settings you want used on your submission form (we don't have the time to try out multiple configurations for each production).
• DirectX 9.0c (December 2006) runtime is available here (web installer) and here (full download) (contains, among other things, d3dx9_24.dll to d3dx9_32.dll).
• If you have no experience on how to make demos look good on the bigscreen, we strongly suggest reading this article by kb/farbrausch.

If you have questions or suggestions about these rules, contact the organizers at .

• Maximum size is 64MB (67108864 bytes) after unzipping/unraring of the demo archive for ALL files, including readmes etc. (Of course you can still have compressed data files with whatever algorithm you prefer). We increased the size limit substantially this year to make it easier for people to use high-resolution or HDR textures if they want to.
• Maximum running time: 8 minutes (including loading/precalc).
• You may assume d3dx9_24.dll to d3dx9_32.dll are installed.
• Java/.NET entries are allowed.

• Maximum size is 65536 bytes for the executable. All other files in the archive will be deleted before showing the entry in the competition.
• Maximum running time: 8 minutes (including loading/precalc).
• Please note that neither msvcr70.dll, msvcr71.dll nor msvcr80.dll will be available on the compo machine!
• You may assume d3dx9_24.dll to d3dx9_32.dll are installed.
• Java/.NET entries are not allowed.

• Maximum size is 4096 bytes for the executable. All other files in the archive will be deleted before showing the entry in the competition.
• Maximum running time: 8 minutes (including loading/precalc).
• For the sake of getting more compatible entries this year, import by ordinal for DLLs with non-fixed ordinals is forbidden (don't even think about directly jumping into DLLs with hardcoded offsets!). Please use alternative, more compatible techniques like muhmacs import by hash to save on executable size. Thanks to peci, we have some import by hash source code available for anyone who is not familiar with the technique. Or just use a 4k packer like Crinkler, which does this automatically.
• It is okay to deliver bigger versions of the 4k along with the compo version (which must be <=4096 bytes) in the same archive. We will not show the bigger version in the compo. If your packer doesn't work on the compo machine, it's your problem. We will be able to provide you with details about the compo machine, though.
• Please note that neither msvcr70.dll, msvcr71.dll nor msvcr80.dll will be available on the compo machine!
• You may assume d3dx9_24.dll to d3dx9_32.dll are installed.
• Java/.NET entries are not allowed.
