i think i figured this bin out and how to hack it.
first off, this is NOT a bootbin you have to binhack. if you look after the cd001 reference, it does not have "gdfs" references after it. neither does SG_DPLDR.BIN. so DON'T BINHACK those 2 .bins. as a matter of fact don't even touch the SG_DPLDR.BIN. its the MAIGO.BIN we have to manually hack in a hex editor.
the SG_DPLDR.BIN file is similar to the GINXFER.BIN file i the Planetweb browsers, which executes or loads/launches the game.
MAIGO.BIN exits the games back to the browser or whatever. but only if the lba is 45000,...........but not any more.
open MAIGO.BIN in a hex editor. go to address,
x00001404 - you should see 5EB0, which is 45150 = 45000+150
now, go to address,
x00001410 - you should see 6EB0, which is 45166 = 45000+166
those are the 2 addresses we must hack in order to exit the game back to the browser successfully at any lba. so its simple. at address, x1404, is your lba+150. at address x1410, is your lba+166.
i have already figured it out for lba's 11700 and 11702.
if your lba is 11700, change it to,
x00001404 = 4A2E
x00001410 = 5A2E
if your lba is 11702, change it to,
x00001404 = 4C2E
x00001410 = 5C2E
now save the file.
i have tested this with the DPP web browser loading up dream library mega drive emu. i play it for a little while, then i exited the emu back to the browser successfully at lba 11702 after hacking the MAIGO.BIN.
so i hope this can help ppl selfbooting the backups and have a fully working disc.
