Yes & yes!
1. open the wad you want to rename.
2. open the maps and extract the magnycours2001 (create a folder for the extraction).
3. open samples & extract both data folders and place them both into the folder from above.
4. now open your extraction folder and rename the track to the track slot you want (magnycours2001 to sepang2001).
5. open this folder and find the following: .cfp .env .vcl .col .hze .bin anything that is NOT .tex, rename them as sepang2001.
6. same with the data folders, open them and rename the .crd & .bin.
7. now go back to the magnycours2001.wad and place your new folders back into their positions and delete the old magnycours files.
8. nearly there rename the wad sepang2001.wad and rename S1CT10.DAT as S1CT02.DAT.
Hopefully that should work! It works for me!!!
