Will the 7z format be supported in the future?

CreepyArcade · Post by **CreepyArcade** » Fri Jan 21, 2005 3:14 pm

Hello,
Not sure if someone already asked this but I am wondering if support for ROMs in the .7z compression format will be supported in a future version. The compression ratio is quite a lot better than .zip and for people with many ROMs this could really save a lot of sidk space. Any thoughts?

JMA compression is already implemented, and compresses more than 7-zip for Snes games.

That, and 7zip's source code is supposedly a mess.

Yes.. why do you want to use 7-zip? If you're looking for better compression, JMA already beats the pants off 7-zip and is already supported in ZSNES.

I'm sure JMA beats that too.

Not to be "that guy" who begs about releases, but I would sure like to be able to play with JMA support...

Nach just needs to finish NSRT 3.3. He says it's easy, but boring.

Yeah, Nach took great care in creating the best compression algorithm for your ROMs. I believe Nach did some comparison testing. He can tell you more.

Where that JMA compression program can be found?

It's called NSRT 3.3. See my above post.

What about RAR files? How does it compare against JMA?

If i remember correctly, JAM is heavily optimized for SNES rom images, so it has better comression ration than RAR.

Ah, I see. Thanks for the info.

Speaking of JMA..
Has anyone even figured out what that stands for?

We talked about it before the board was wiped, but I can't remember for the life of me...

JMA is better than everything else for snes roms. Except, of course, BARF. But this one is just cheating anyway.

JMA Mega Archive.

Or it could be grin's idea of NRC -- Nach R0xx0rz Compression. I still remember that.

All popular formats fail in comparison to the size savings JMA offers.
JMA is also now available.

Yeah yeah, now pester Kode to let it be used in VBA too. Hehe.

JMA is Mega Awesome [Awesome*2^20]
Can't wait for the future version, JGA Giga Archive, with compression approaching BARF!
The only archiver as good as BARF is a CD burner...

What the hell is BARF?
