Street Fighter Alpha Anthology (PS2) Rom Extraction?

SLUS-21317 has a large `x_data.bin` on the disc. Has anyone looked at extracting from this file format? The initial few bytes were an AFS header, but afs.bms didn't work.

I'm mostly interested in extracting the bundled CPS-2 romfiles that can be found (look for /CPS2 string)

I guess this script works with that format:

Ah, could you please provide the whole x_data.bin?
I see some compressed files and want to check them since the original afs format doesn't use compression.

aluigi sure many thanks for your help, as mentioned I did try afs.bms and it didn't work out of the box, I've sent you the full file via wetransfer, you can download it from here

Ok I fixed the script (the archive referenced a names table after the archive that wasn't available) but no idea for the compression of the files, mainly because there is no decompressed size.
