ScummVM to read from ZIP/RAR

ageorgios · Post by **ageorgios** » Wed Nov 28, 2007 12:12 pm

Iphone has restricted memory, so every MB is worthy.
Is it easy for ScummVM to read from zip or rar files internally and not request the game to be unzipped?
This would be of great value.

I know there are compress tools, but:
1: they are lossy (ok not big deal for iphone)
2: only for sound

This question has been answered loads of times already, please search the forum and read the FAQ before asking.

Check our FAQ:
http://www.scummvm.org/faq.php#id2551517

There is support for sound compression in MP3/OGG/FLAC if you wish to save space (though I believe the iPhone port doesn't support FLAC compression yet). FLAC is not a lossy compression, so once this gets supported you will have lossless sound compression (but as you said yourself it doesn't make any difference for iPhone)

yeap, sorry about asking again, i didn't read the faq first.

but I think it is good to reconsider, in mobile devices space is critical...

anyway thanx for the scummvm whatsoever!

Compressing specific files (like sound / video files) with dedicated compressors will always give much better results than generic .zip or .rar compression.

Furthermore, no, it's not easily possible to read from a compressed .zip or .rar file on the fly without extracting it first -- though you can extract it to RAM, but that only helps if you have lots of RAM. Which you usually don't if you are that short on permanent storage
