Revision: 1.11
Committed: 2001-07-01T14:38:02Z (22 years, 10 months ago) by cebix
Branch: MAIN
Changes since 1.10: +39 -51 lines
Log Message: 
- sony.cpp/disk.cpp/cdrom.cpp use vector<> of drive_info objects instead of
  linked list
- color depth switching updates slot ROM
- video_x.cpp always supports 1-bit window modes
- timer_create()/clock_gettime() are pulled from librt if present
