PS1/2 Compressing PS1/PS2 games

[Ygolonac]

So do you guys compress your roms for stuff like PS1, Dreamcast of PS2? What are the disadvantages of it? I've seen compressed PS1 games at like 20MB. Does the sound and cutscene quality go to shit? Was thinking compressing Ps1 would be good for retroidpocket 2.

I think this post details what you're talking about, but it looks like it involves stripping out music and videos.

if you're using retroarch, you can compress them into chd files. Those are lossless, but they aren't going to get THAT small.

There are also ways to reduce the size of PS2 games -- language files for languages you don't need, for example, could be removed to save some space, or you can compress the cut scene videos. I have also read somewhere that some games contain dummy data that can be removed to save space, but I can't seem to find it at the moment. Here is a post hosted on PS2-home that you can check out if you want to read more.

I haven't done any of this myself though, as it seems to be a lot of work if it should be applied to all the games
