About Doom: First I searched for the real WAD's. Doom1.wad u have is the SHAREWARE version with 1 episode. U can find the real wad's by searching the doom full games on the better filesharing progs, they aren't big (20mb or smt). They are in the corresponding doom folder after installing, just copy paste or cut them.
doomu.wad = ult doom
Doom.wad = doom 1
Doom2.wad = doom2
doomf.wad = final doom
doom1.wad = shareware
Then after i got it what i did was going to DCemulation.com and then get nesterdc jimnesboot.bat there, i was quite desperate and a newbie :P I used the bat with the doom files instead of NES files.
When unrarring jimnesboot you automaticly get the right directories en folders so u don't have to do squat. I putted doom's ip.bin and 1st read into \NESDC\ directory (not in a folder) along with all the .wads and the .elf. Thats it. I ran the .bat and it auto made a selfboot .cdi which, against my expectations, worked perfect on the DC!
I even kinda did this with quake1.
