Add Knights of Xentar

[tomojira]

Knights of Xentar

• v2.0, installed from CD matching with TDC#23 entry: Knights of Xentar v2.0 (1996)(MegaTech Software) [ISO]
• CD must be inserted for the game to run. For whatever reason, DOSBox Pure wouldn't mount it after I converted it to CHD, so I left it as the ISO
• This CD version is fully voice acted, unlike the floppy version
• INSTALL.CFG must exist for the game to run, but can be generated at any time by running D:\INSTALL.EXE and installing to C:\
• DoDAT can build this directly from the disc image

DOSC

• Sound Blaster and other config
• BAT file for running the game. May not be necessary, but included just in case
• cpu_year: 1985 attempts to slow down the game. Even at this low speed, the NPC movement still looks too fast, but I couldn't go any lower because 386 is supposed to be the minimum: https://www.mobygames.com/game/1665/knights-of-xentar/cover/group-2780/cover-111567/
• Auto start
• input_directmouse is not enabled because it causes some glitchy cursor movement
