Need help with changing disks with multiple versions of the same game in Rocket Launcher

[AnonymousMOS]

Hello, 

I'd be grateful if someone could help with this. 

I have multiple versions of many games for the Commodore c64. I know my problem has something to do with my folder hierarchy or file naming. I just don't know how to go about organizing to fix the problem.

Example: California Games has several versions, from different sceners of the time, so I have them laid out like this:

California Games (Epyx) <- Folder
          [ESI] <- Folder
               California Games (Disk 1 Side 1).d64
               California Games (Disk 1 Side 2).d64
          [REM] <- Folder
               California Games (Disk 1 Side 1).d64
               California Games (Disk 1 Side 2).d64
               California Games (Disk 2 Side 1).d64

Etc...

I Keep the disk names the same so the manual will show up in pause too.
But the problem is when I go to change disks, I have all the disks show up as options, instead of ONLY the [ESI] version, or the [REM] version.

The only thing that I've come up with is to append the version after the (Disk 1 Side 1) just so I can differentiate between all of them. ex. California Games (Disk 1 Side 1) [ESI].d64 and California Games (Disk 1 Side 1) [REM].d64

Any help sorting this out would be much appreciated! :-)
Thanks!
