Hey SMiTH, I followed your steps but I feel like the image is missing something.. When I boot it up the dreamcast thinks its a music disc. Also, when running hack3 on the .bin files that I extracted from the .gdi file, they don't seem to get modified (according to the file explorer). Any additional advice? Isn't there supposed to be dummy data or something?
I'm attempting this on Windows XP. I also used the Python scripts and additional tools found here
http://dreamcast-talk.com/forum/viewtopic.php?f=2&t=6694Honestly I'm really just trying to remove the ECHELON banner on one of my games and I think the .gdi version I found is clean. If anyone has any useful tips I'm all ears. Hex editing the 1ST_READ.bin & attempting to recompile the .cdi has been a hopeless effort.. Converting the .gdi to a .cdi to me seems to be most promising..
