Video Not Working? Fix It Now

Back in the day, playing games that came on multiple discs could be SO irritating. 20 years later, I fixed it.

CDROMs connect to the IDE/ATA port, but they do not speak the same language as hard drives; they use ATAPI, which is generally described as "SCSI over IDE." This I knew, but I thought it was a limited subset. I never imagined that it supported LUNs, but it does. So an "IDE" CDROM can absolutely appear as two, five, or even seven devices, with no special software. This has actually led to bugs! Some CD-RW drives do not check the LUN field before responding to a command, so when the OS scans the bus, the drive can appear as seven separate drives. This happened on both Windows XP and Linux, at least. Linux received a patch that uses a heuristic to avoid this situation, which is probably why you've never seen it. 22:05 I don't know how I did this, but the album name here is wrong. that's a Jeff Rosenstock album. I haven't even thought about Jeff in weeks. the correct album name is _I Don't Know What I'm Doing._ To be fair to myself, both of these names / artists are highly self deprecating.
