wow...you made that too hard for yourself!
i ended up going here
http://homebrew.dcemulation.com/dreamcastdoom.htm
and grabbing the .sbi version of doom. you can learn all about .sbi's for
www.sbiffy.com . i ran the .sbi and then went into the inducer directory and put in the .wad files. after that i used the inducer to make an image disk.....VOILA!!! it worked!
but i do have a question about quake.......what files do i need to run it? quake doesn't have any .wad files, in fact all i saw were .dll files.
thanks again for the feedback guys!
