* Rewrite video emulation. Features:tg2001-07-241-102/+100
| | | | | | | | | | | | | | | | | - slightly more accurate VGA hardware emulation; - more int 10 functions, especially wrt to palette handling; - first shot at graphics support; - mode switching. Bugs: - graphics too slow; - only 16 color modes work for now; - works only under X, and only with 16 bit TrueColor visuals; - far from being genuinely useful (I can play an old EGA game now, though (mahjongg.exe)). Also, the code has been cleaned up a bit (more to come in a separate commit).

* Unbreak doscmd after the sigset_t change:marcel1999-09-291-0/+4
| | | | | | | | | | | | doscmd heavily depends on struct sigcontext which luckily is mostly passed between functions as usion regcontext_t. By redefining union regcontext_t in terms of mcontext_t almost all bases are covered. It also seems to me that doscmd was in a transitional state. The redundant definitions made it difficult to get a clear overview and could easily cause oversight. To make sure my changes were ok, I went as far as to complete the transition. It was not exactly necessary, but I expect to have to come back here some more ("whistle" if I'm wrong :-).

* Make sourcer's main program execute in X mode.imp1998-07-011-1/+3
| | | | | | | | o Make the dos emulation treat c: and C: the same way. Sourcer was doing a chdir("c:\\") rather than a chdir("C:\\"); o use drlton() in all places where we used to use -'A' so that we're always case independent. o use drntol() in all places where we used to use + 'A' for similar reasons
* Add support for EMS emulation to doscmd. This requires changing thejlemon1997-09-301-1/+10
| | | | | | | | | interface for callbacks to doscmd from DOS, obsoleting the instbsdi redirector. (redir.com replaces it) A temporary hack is in place so the instbsdi program will (hopefully) work in the short term. Submitted by: Helmut F. Wirth <hfwirth@ping.at>
