The reason  some PWADs do not work is because of what they were made for.  Most PWADs after say 2000 were made for newer source ports like prboom and zDoom.  I am just assuming that nDoom is based off of the original DooM source code at iD's website.
prboom and zDoom improved upon DooM's WAD format and it's different kinds of chunks adding features that weren't in the original DooM engine.
If you really want support for these something like zDoom would have to be ported instead of DooM.  I would imagine that it wouldn't be that much harder than porting Doom, except that zDoom has modified the software renderer and added a hardware one, and those add some features to the DooM engine.

hey guys I have a problem playing Doom 1 ultimate
after finishing an episode
the screen just turns kinda reddish and showing some sort of credit list (? maybe not coz cant really read the words in reddish style)
and the game just seems to freeze and not responding to any key strokes
any thoughts?

Haha thanks for the heartwarming welcome
Me myself loves toying with calculators
but in no way near the levels you guys have been achieving!

My calculator model is TI-nspire CX CAS
I suppose I can spend several minutes to end the last stage now and take a picture of the situation

Hmm that almost looks like a glitch with the damage effect. When you get hit the screen turns red and it seems like some compatibility issues with Ndless or the hardware causes it to be permanent. X.x

By the way as an advice, do not double-post unless it has been 24 hours. It's best to use the modify/quick modify button instead.

I haz the same problem and in doom 1 when you pick up the armour that lets you walk on acid it turns red

Exact same problem. I deleted my save because of it... but I beat THE GAME later (that's when you walk on the star where you die instantly? right?)

You can only complete the 1st episode of Doom by dying.
And the screen is red when you take damage.

So a little bug just gives you red credit screens.


On the real Doom, there is nothing you can do at the credit screens - you have to use the menu to run a new game with the same or another episode.

It seems that the credit screens script isn't very well supported for now, like the menu and the automatic demo when you run the game (Mrakoplaz has left several comments about these in the code).

So without the menu support, all you have to do at the credit screen is to exit and relaunch nDoom.

You mean Doom Ultimate, right? Because for me I got no problem in Doom 1's first level

Doom Shareware = Doom1 episode 1

I don't remember if the ending credits are different.
