Thanks to:

- ExtendeD for Ndless



Installation:
************
- Install Ndless 3.1 on your calculator
- send "ndoom.tns" to your calculator
- take Doom/DoomII compatible IWAD files and change their extensions from ".wad" to ".wad.tns"
- send the ".wad.tns" files to your calculator
- if necessary, add a "ext.wad=ndoom" line to your "ndless.cfg.tns" file



Supported games:
***************
There exists two types of WAD files:
- IWAD files which include complete game data
- PWAD files which are patches with partial data, designed to be loaded over an IWAD

nDoom currently only supports IWAD files.
Note that most 3rd party WAD files available on the Internet are PWAD files, and won't work with the current version.

Only IWAD files compatible with the Doom or Doom II format are supported. IWAD files from other Id Software games (Heretic, Hexen...) won't work.

The Id Software supported IWAD files are:
- Doom ShareWare 	(usually "doom1.wad")		(Doom IWAD format)
- Doom registered	(usually "doom.wad")		(Doom IWAD format)
- Ultimate Doom		(usually "doomu.wad")		(Doom IWAD format)
- Doom II		(usually "doom2.wad")		(Doom II IWAD format)
- Final Doom - Plutonia	(usually "plutonia.wad")	(Doom II IWAD format)
- Final Doom - TNT	(usually "tnt.wad")		(Doom II IWAD format)

New in version 2.11 (28/01/2012):
*******************************
- turned some WAD fatal errors into warning messages into warning messages
in order to be able to open more PWAD files (with some graphic glitches)


New in version 2.12 (06/02/2012):
********************************
- added support to directly open wad files from the OS browser (needs Ndless 3.1 r350 at least, and a correctly set up ndless.cfg.tns)
- partially fixed the wad close bug: if the game is exited correctly, you should be able to delete the used wad file
if the game does crash, that's another problem...

********************************
- patches ndless.cfg.tns if necessary on 1st run in order to directly open wad files from the Nspire doc browser

- now correct support of the CX 2nd timer, needed for screen fading

New in version 2.3 (27/03/2016):
********************************
- TI-Nspire CX CR4 new screen support

New in version 2.4 (19/09/2020):
********************************
- TI-Nspire CX II screen support



Todo list:
*********
- Need to fix the error dialog boxes bug once the game has started (which should not happen) - freeze after the dialog box instead of quit.
- Need to fix end of episode/game animations which seem to freeze sometimes
