Yeah, getting all translations at once may be an issue. Here's a quick modification of script I used to work with Sumaga scripts before tlwiki sold out: http://www.tsukuru.info/tlwiki/images/7/7d/Imas-wiki-1.0.tar.bz2
to get all scripts (you need make program. If on windows, you'll have to install it. I use cygwin but you probably don't need all of it; gnuwin32 will be enough), make update
to download new versions of files if someone changed them on wiki, make commit
to upload your modifications and make resolve
to upload conflicting files.
What about the slowness issue?
I think ICL compiled files can be linked with gcc; So you can compile lzss.c with ICL and everything else with gcc; I can add you to project on google and you can commit necessary changes too I guess. Shall I?KAMI-EDIT : Please use the edit function, do not double-post.
