PS1/2 Files on CDFS

[Forcystos]

Long story short: I want to load files from CD/DVD (not sure which one would be proper) from both uLaunchELF and SNES-Station. I have both of those installed on my memory card along with FMCB. I have tried both types of media and followed various tutorials across the internet, and even my own desperate attempts, all of which have been unsuccessful. The question is: how can I get either of these applications to read from CDFS?
