19// Revision 1.9 2006-04-15 22:08:36 kkurbjun
20// Slight code cleanups, fixed sound parameter - now it saves. Old configurations will be reset.
21//
22// Revision 1.8 2006-04-14 21:07:55 kkurbjun
23// Start of profiling support for doom.
24//
25// Revision 1.7 2006-04-04 11:16:44 dave
26// Correct the #ifdef logic for timer_unregister() and add a comment describing why we need to surround the use of the user timer with #ifdefs
27//
28// Revision 1.6 2006-04-03 17:32:46 dave
29// Clean up the (incorrect) #ifdef spaghetti for the timer. We now have a user timer on the ipods, so we use it.
30//
31// Revision 1.5 2006-04-03 17:11:42 kkurbjun
32// Finishing touches
33//
34// Revision 1.4 2006-04-03 17:00:56 dave
35// Doom can't use the user timer at the same time as using the grayscale lib.
36//
37// Revision 1.3 2006-04-02 12:45:29 amiconn
38// Use TIMER_FREQ for timers in plugins. Fixes timer speed on iPod.
39//
40// Revision 1.2 2006-04-02 01:52:44 kkurbjun
41// Update adds prboom's high resolution support, also makes the scaling for platforms w/ resolution less then 320x200 much nicer. IDoom's lookup table code has been removed. Also fixed a pallete bug. Some graphic errors are present in menu and status bar. Also updates some headers and output formatting.
42//
43// Revision 1.1 2006-03-28 15:44:01 dave
44// Patch #2969 - Doom! Currently only working on the H300.

74 The user timer is used to generate a 70Hz tick for Doom. But it
75 is unavailable for the greyscale targets (it's used by the greyscale
76 lib) and is not implemented in the simulator - so we have to
77 approximate it using current_tick.
