Well, let us look at the requirements again.
"The size of the source code file(s) shouldn't exceed 5KB".
"Email us a zipped file which contains the following items:"
"- the source code;"
"- a demo that showcases your snippet;"
"Send your entry / entries by email to resources@acknex.net if its / their size doesn't exceed 5MB;"
It indicates that the source code is no longer than 200 lines and less than 5KB, but the demo can be any size.
In XICE's project, only Xdebug.c is the source code which is just 9 KB.
We cannot, of course, count the help.html file as part of the source code. According to the instruction he gave in the help.htm, we know that sample_1.c, sample_2.c and sample_3.c are just samples of Xdebug, and skycube+6.dds, small are only used by these samples.
I think his entry does not violate the rules of the contest, or it would be rejected.
