So I'm ripping all of my PS2 games and I noticed that the Sonic Mega Collection Plus is a whole 4.7GB, filling the entire DVD. Given that it's a collection of Genesis games, what could be taking up all that space?
A few dozen megabytes for the games and the launcher
About 1GB in video files
3GB in a file called _DUMMY_.BIN which contains nothing but NUL bytes
FWIW at least among my collection it's pretty rare for a game to fill the entire DVD, and when it does it's usually likely to be using the storage legitimately.
Anyway I'm done ripping all(*) my PS2(**) games and installing them to my SSD. Maybe I'll actually play some of them someday.
I'm surprised I "only" have 48 PS2 games in all. I thought I had more.
* Dance Factory failed to rip but it's unplayably awful and also wouldn't work as an HDLoader game anyway since it requires disc swapping so who cares
** as in PS2-native, as I haven't done any PS1 games, many of which also wouldn't work right with HDLoader anyway since they require disc swaps
@fluffy This is why the Dolphin emulator devs implemented a unique lossless compressed disc format to crunch junk data especially well. An extreme but real example (and the only game I ever worked on that saw store shelves... and it shouldn't have). How often does a file compress to under 0.3% of original size?
Interestingly, Windows' built-in file compression brings this particular ISO down to about 0.6%. RVZ outperforms greatly on games with non-contiguous junk.
