If you don't have an m3u, you need to manually append all of the discs a game has through the Disc Control menu.

Just not sure how that translates here (meaning what method is used differently for Sega CD)? Again, my PlayStation setup works perfectly using m3u's and the disc controller menu.

Are you saying I should just have two discs in the game list menu of emulationstation, then back out o f the emulator first when I come to the end of disc one, and then just load the second disc? Will the game save continue like that? Bit confused on this part here. When you say 'go to disc2,' how would you do that with no Disc Controller option like with the PlayStation? Far as I can tell, there is no way to eject disc 1 and load disc 2 in-game and continue on. Thanks, but this is the sticking point for me. Just not sure how that translates here (meaning what method is used differently for Sega said in Sega CD Discs/M3U said in Sega CD Discs/M3U said in Sega CD Discs/M3U Failure?: Load the game from the 1st disc, then - when prompted - go to disc2. So is there just no way of loading Sega CD multi disc games on Pie? Do I have to remove them from my collection (which I would HATE to do). Or am I said in Sega CD Discs/M3U said in Sega CD Discs/M3U Failure?: So I figure someone must have came up with a reasonable solution. How would I assign a different emulator for each dual-disc game? And how would they display in my file list, if M3U is not supported? I assume I'm not the only one that wants a complete Sega CD collection represented in their menu, including the dual disc games. I'm a bit confused at how people run multi-disc Sega CD games on their Pie right now. The link to the doc above references the lr-picodrive being the go-to for multi-disc games, but it does not list M3U in the supported file formats. We've established above the same M3U setup for PSX won't work for Sega CD, as it's not supported (and no ' Disc Control' option appears in the Sega CD quick menu either, like it does for PlayStation).

The issue was, I'm trying to find the best solution to incorporate Sega CD games that have multiple discs into my RetroPie setup (the same as I would with PlayStation, which works perfectly). However, I'm afraid I'm no further along than before. After some time away, I'm finally able to get back to working on my multi-disc Sega CD collection.
