WinRAR question

[thread_of_fate]

Hey i was just wondering, i dled Bloody roar 2 from the psx iso temple and they got a friggin 500 mb file down to 13 mb. Does anyone know how to do this? It would make uploading alot easier .

[thread_of_fate]

Or maybe it wasn't WinRAR that this person used i dunno anyone know ANY program to squish your files down to small sizes like that?

If i'm not mistaken bloody roar isn't that big of a file and 13mb sounds right. Just like penny racer is a game thats only like 8mb big, but when unpacked it's around 500+mb. Its because of what I like to call "fake" memory sectors. I don't really remember why this is but what I do remember is that games that have a lot of fmv like square games will actually be around 200+mb big, its usually the fmv that make psx cd's big, the actual playing game on most psx cd's is only around 40+mb big. I dont know but I think that the bad sectors go in those "fake" memory spots aswell and the psx console needs that to actually run the game.
So games like ff7 will not be compressed down to like 30+mb unless you rip out the fmv's out of the disc.

I think they just ripped ou the FMVs and some of the music. That way there's a lot of empty space but it keeps it's total filesize. All it does is fill in the ripped space with 0s, which are a lot easier to compress when all the other letters aren't thrown in there. (Scientific notation, I believe they'd use, if I got the way these files are made up right, with binary.).

That's how it was explained to me. Ripped ISOs are a lot easier on the space, and no one really plays for the videos anyways, unless they're REALLY good videos.

You might be right, but when it comes to Square or most any other RPG, the fmv's are vital.

Hmm I see...thanks for your help. The game had music and fmv's ripped and was about 512 mb after being unRared.

maybe whole multimedia inside the game wasnt compressed by any kind. like you have PC game with uncompressed AVIs as movies, WAVs as sound, and BMPs as pictures. so it could be compressed to 13mb if it's uncompressed. take the example : you have the same picture in JPG format and in BMP format. it's same pic, but JPG is 50kb big, and BMP is 2 megs big. try to zip up jpg file, you'll get 0,05% of compression. zip up BMP and the compression is stunning 80%. why? because JPG is already compressed and BMP isnt. same thing like in your case, i suppose.

another example: try to zip an MP3.

[gannondorf]

exacly that. mp3 is already compressed.
