Welcome to Defence Force!
This is a work in progress attempt at rewritting the main site.
You can find all the important sub sites can be accessed from the left hand bar.

The legacy content is still available on the old site but will hopefully be migrated and modernized over time.

If you are interested in knowing what is happening, you have multiple options:
  • Twitter (useful for downtime notices, new videos or blog articles announcement)
  • The Defence Force and OSDK Facebook pages
  • The Youtube channel
  • ...or just go through the change history down there!

  OSDK 1.15
Sat 7th September 2019   

  • Upgraded the C compiler to version 1.38 by integrating all the latest changes from Fabrice Frances: Fixes some issues found by Goyo and Retroric regarding encoding of data tables by the compiler.
  • Changed back the default compile optimization level from -O3 to -O2 - there are still some cases of bad code generation
  • Fixed a problem with include/sys/sound.h containing invalid symbols that don't compile correctly

  OSDK 1.14
Sat 8th June 2019   

  • Upgraded the C compiler to version 1.36 by integrating all the latest changes from Fabrice Frances:
    • Better code generator
    • float/int conversion fixes
    • better error handling
  • Changed the default compile optimization level from -O2 to -O3 - providing significantly better code generation, both in size and speed
  • The code generator macro file is now compatible with both XA and FRASM
  • Upgraded Link65 to the version 0.66: The new macro file generate lines that contain multiple instructions, the linker stopped at the first encountered instruction, this new version correctly parses that
  • Updated FilePack version number to 0.2 to 0.5 after somebody reported an issue with a veryyyyyyy old version which happened to have the same version number of a much more recent one.
  • Tap2Dsk 2.1.1: Added a fix to avoid the tool to stay stuck on tapes with incorrect size specified in their headers
  • Fixed a problem with itoa not correctly processing negative numbers (the '-'' was overwritten by the number printing routine). Also took the opportunity to optimize the code (removed the jsr itoa / rts as well as an unnecessary x register clearing (it's set to zero when we are back from udiv10)
  • Added support for %u to printf

  Server Failure
Thu 30th May 2019   

  • For some reason, the power supply of the webserver died, and in the process corrupted the filesystem. Took a bit of time, but thanks to rfm and tomreyn from #ubuntu (the freenode IRC support channel), we are mostly back in business.
  • I'll probably have to monitor the machine, do some more checks, and at some point replace the PSU by a new one (right now we are running from an old one that was laying in a cupboard...), so expect some occasional reboots.

  • Fixed the library functions 'scanf' and 'sscanf' (For some reason these files had not been converted to use the XA syntax when we switched from FRASM)
  • Upgraded the version of Sedoric 3 used by Tap2DSK with the patch that improves the handling of the "insert master disk" prompt
  • Modified the Oricutron batch file to use PUSHD/POPD instead of CD, this makes it possible to start the emulator even when the project is on another disk drive location

    Wed 7th February 2001   

    • General update on the oric library !!!

    Check out the page to learn the latest news on big money consumer incursions.
    If you are tired of paying for everything and for nothing for all the bad reasons in the world, sign the petition.

    Ensuring that 'poor' artists continue to earn their money is not a bad thing in itself. But taxing everything and everything becomes downright disgusting ...

    For example, I have a CD burner, two PCs, an Atari Mega STE and a network oric, as well as a DreamCast console and a PlayStation (one).
    After a quick calculation, I came to about 120 original software, 16 DVD movies, a good fifty audio CDs, and 3 games in pirate version.
    Yes, 3 pirated games, but these are games that I own the original that do not run on my PC because of the protection.
    The music ? I buy CDs whenever I want. So why a burner?
    Well for backing up, archiving, exchanging data between home and work, and transferring oric software from their cassettes to audio CDs (more reliable!).

    My question: Why should I pay a tax on products that do not serve me to harm copyright?

    (Basically, this page explains why some French organisation wants to apply a taxation on any numeric product that can be used to store, stream, listen any numeric data that could be protected by copyrights...)
