I know this isn't updated anymore, but in its options, is there a way to set the game to 240p? I know DOOM is only 320x200@35, but this port had many things done to it to look more like a proper console port, like framerate (can reach up to 60FPS) and controls (although I much rather play using the GC controller).
After acquiring a CRT PC monitor and playing Chocolate DOOM on PC, I can see how beautiful the game looks as it was originally intended. But since this is a more "recent" monitor (2006) I was forced to set a 144hz refresh rate to play at 320x200, because this is 31khz only, and I would need a 15khz monitor to play at the intended 320x200@75hz. Here's the results:
Since this is a PC monitor, I can safely set such a low resolution/line count without issues. It is "stretched" to 4:3, so it's the correct aspect ratio as well. It's truly amazing playing the game like this. I never played DOOM when it came out originally, but I would imagine someone having "nostalgiagasms" looking at this (I don't know if that's really what it was supposed to look like though XD).
I see that the Wii port doesn't stretch the image, maintaining its pixel count so it doesn't need filtering/interpolation, but the aspect ratio becomes weird that way. The game is playable though, but on a CRT TV it's just not right to play DOOM at 480i. All the other console "true" DOOM ports (as in not counting the modern ports which might be using emulation) managed 240p somehow, even the SNES port, with it's windowed mode of sorts XD. It would be great to see this port do the same.
