I need help with packing

I'm working on a C64 project which requires a lot of loading from disk. I have already got easy with The Dreams fast loader. In order to decrease disk drive access I'm thinking about compressing the datas. I know there are some tools that can compress datas, but I've never worked with them. What I need is:
-a tool that can pack the original data into a file;
-the part of code to insert into my assembler routine, which can unpack the data to memory after loading.

Can anybody suggest me a good packing tool with instructions?

thanks, Ready.

From Author's site aswell :)

Can be used to crunch executables (sfx) or level files.

When I searched CSDb for Exomizer earlier I only found that old version but now that entry has been changed to v2.0beta3?
I don't think it's a good idea to alter an entry like that, the old version deserves its place & the newer one should have an own entry instead.

Yes you're right Zyron, that's the right way.
Also because the 2.x series has a different command syntax.
Btw, that was _THE_ Plus/4 site ;)

there are loaders with built-in depackers..
actually, the best overall loading speed (including depacking) is achieved only with loaders that depack while loading.
i'll add exomizer support to my loader as soon as v2.0 release is out. :D

..like ByteBoozer, it's too good not to be used :). Get the latest version from your favourite tool dealer Booze Design :DD <back after commercial break>.

Exomizer works fine with Apple II series of machines also.

ByteBoozer > all.

What do you mean I'm biased?!?

Anyone knows if somebody has done a cruncher in java? It will probably have a performance loss compared to C but I want to incorporate it into my new Assembler.

There's also a cross-platform cruncher called PuCrunch. It packs faster, but Exomizer can do better results, and has a built in programmable depacker. :)
