So, I’m playing Metal Gear Solid and it has 2 disks, I got to the end of disk 1, and well…

First I tried with the Disk Control>>Load New Disk which is a legacy feature apparently so well, it didn’t work. Okay, so I search and there’s some .m3u thing, I watch a video, pretty simple all in all. I get all my files in one folder and inside that folder I get the .m3u file which inside contains all the name of the .cue files. I boot, try with this new method, nothing. What do I do?
