CDoom v2.05 reference

FEATURES:

Music system: support opl2/opl3/mpu401, the only engine that have music
equal doom2.exe original.

True 3d gameplay: optional, can be changed in the options menu.

Jump: use the key ';'(default), with the cheat JET, can toggle fly mode.

3d floors: very fast rendering, may have some bugs, in development yet, when
running a map with one 3d floor is as if added one sector more, when adding
many 3d floors, slow down little(see Metro1,Metro2,Metro3,Mercurio test maps).

Monsters infight: dehacked option added, for imps against imps, etc.

Sound: works with a SB or compatible card, is a simplified driver. Please,
let me know if works in your computer or no. If yes, tell me what is your
sound card, if possible dsp version, if compatible with SB or no. I will
intend to build a better sound reference in this file.

ENHANCEMENTS:

Detection of blockmap/reject ausent to avoid crash when one of this resources
are missed, or for automatic blockmap building by CDoom.

Blockmap collision better in huge maps, Metro1.wad,Metro2.wad,Metro3.wad.
When running this maps in MBF, some blockmap points don�t collide properly.

Fast video code: run under WIN NT, not tested in linux dosemu, please test
and tell me. Very optimized.

Demo playback: maximum compatibility with doom2.exe v1.9 and MBF v2.03,
boom demos may not playback properly. Few demos of doom2.exe v1.9 may
desync(eternal et312223). There is demos bad recorded that desync with
doom2.exe too.

General speed: extremely optimized, sound code fast, 3d floor code don�t
slow down the program, video code fast, is possible some more optimization.
The speed of -fastdemo nx22-051 in a pentium 233 is 227 fps maximum. Faster
than doom2.exe. The only engine that is faster than CDoom is Boom 2.02
because use __djgpp_bearptr_enable and use a video mode that is a standard
VGA. CDoom uses unchained VGA mode, with page flipping.

This is not a enhancement, but CDoom is a very objective engine, very small
size, removed all allegro functions and other doom unused functions. I made
my own sound library in External.c an the all external access functions.

NOTES:

If sound don�t work in WINNT, use VDMsound library and tell me if works,
please.
For building 3d floors, there is a special rule(maybe a bug) in CDoom v2.05.
First add the lowest 3d floor(lynetypes 281,400 for solid 3d floors and 403
for liquid 3d floors), later the second lowest and so on, until the last be
the highest, this is to avoid rendering the lowest plane above the highest
and vice versa causing some rendering errors,and to avoid that the lightlevel
be wrong.
Future updates of this file may be possibles.
Note that the features of this port are covered by other ports, but the
diference is that CDoom is very faster than other except Boom 2.02. But take
care, boom uses __djgpp_nearptr_enable, disprotect the memory, may cause data
lost and cannot run in WINNT, linux DOSEMU.
