Segagen

[weezee]

Your bad move. You don't know how to selfboot and you start with one of the most difficult tasks. I suggest that you first learn how to selfboot something easy, THEN try segagen.
BTW, install WinASPI. Probably this will let you use CDRWin.
AFAIK, and as jeffman said, SegaGen MUST be at 11700, NOT 11702. I get 11702 when I use cdrecord, but I get 11700 when I use CDRWin. Also *NOTHING* must be read-only! Remove EVERY read-only attribute from EVERY file you're going to use.
Last, binhack ip.bin and 1st_read.bin ONLY, nothing else.
ip.bin is not "created" from 1st_read.bin: it should be in the obsidian zip, or anyway you can use any other ip.bin from any other emulator/game. Then insert ip.bin in data.iso with ipins.
