maybe some one can dumpster dive for old hdd's / disks.
now there maybe more old DE maverick roms before they became sega.
the 1.0 set seems to have the sega sound rom's

You may be surprised or shocked to know that most companies simply do not have copies of their old software or source code
things like secure source safe etc just were not a thing back in the day
floppy disks flying down the hallways was high tech
And that plastic floppy rolodex was secure backup
now days you can just pop in sourcetree and meander back to the alpha 0.009 commit
Gets even weirder when it's like
"Hey guys! if got the original source!"
YAY
"Its on a quik80 tape in a proprietary backup format"
Wa wa waaaaaah
or a zip disk, or a 5.25 floppy, or an LS-120 disk
