Revision: 1.57
Committed: Mon Aug 20 22:09:04 2007 UTC (16 years, 9 months ago) by root
Branch: MAIN
Changes since 1.56: +0 -5 lines
Log Message:
- include experience table as our first generic resource file
- swizzle init code around
- do not calculate checksum in cfutil but when loading the facedata.
  this increases loading time by 20%, but since thats just 1.2s instead
  of 1.0s its not worth the extra effort of doing it beforehand.
