Third time making this comment ffs.
Is there a way to Rip CD Quality audio and FMVs out of these Roms and only leave the binary/game data to trim the ISO/Rom size?
I remember having pirated PS1 game ISOs like Tekken 3 and C:The Contra Adventure which had their FMVs replaced with a dummy/stub file which drastically reduced their file sizes to around 30-50mb uncompressed.
Really? in 2025?
In this game?
Download the game, and erase all the tracks you want from Track2.bin (or similar name) until the last .bin file.
You only need to
NOT erase Track1 in .bin (which is the proper game) and the .cue file.
Protect those 2 files from the wipe out. You listen?
Easy as that.
About the FMV? the few FMVs are integrated inside the game Track01.bin (or similar name), and I don't fucking know how to cut them. Maybe they are editors of FMV video for Mega CD games outside there, but I don't know.
In any case, this game, without the CD audio tracks, gets a huge chunck of its data erased. Almost 500MB of data out, for what I can see. The Track01 occupies like about 83MB only. The .cue is just few KB.
That's all.
PLUS: I will recommend you, before you erase all those tracks, to mount the game as a virtual disc in your PC, using some program like Daemon Tools. Then, open the virtual mounted CD as an audio CD, listen the tracks, and decide which ones do you really not want.
Like for example, the music tracks, which probably are the bigger ones.
If you do that, you could also enter inside the "game" files, opening the CD as a folder, and see what kind of files uses, and search in the internet how to edit them.
