New compression algorithms to add

[aluigi]

Feel free to link here any compression algorithm that is not currently available in quickbms.

Doesn't matter if you have the source code or only the binary dump of the function, everything is welcome

Ok! Here one - for Zen Studios games. Masm32

[RetroHelix]

Would be nice if these algorithms could be added: http://www.romhacking.net/utilities/826/ The download comes with source files.

@ RetroHelix
I think that some of them are already implemented in quickbms, but without samples for each algorithm I'm sure that for me is more simple to add all of them directly to the next quickbms rather than checking each one

I encoded the history.txt that came with the tool to make some sample files in case you want to test your implementation in quickbms.

Thanks a lot, I have checked it and the following are already implemented:

Code: Select all

LZSS history (LZ10).txt = LZ77WII and NITROSDK
LZX-evb history (LZ11).txt = LZ77WII
RLE history.txt = LZ77WII and NITROSDK

So those to implement are:

Code: Select all

BLZ history.txt
LZE history.txt
LZX-ewl history (LZ40).txt

Very nice! Thank you very much.

Can you implement LZEXE? The code for both compression and decompression can be found here: http://bellard.org/lzexe.html

[aluigi]

If you mean the algorithm with the magic "FAB", yes it will be implemented in the next version.
It's used in scummvm so it's very easy for me to implement it.
I don't know if the one in lzexe is the same but I will implement also the code of unlzexe5.c

STALKER compression open source'd (code) from OpenXRay Engine - https://github.com/OpenXRay/xray-16/blo ... /LzHuf.cpp

Great, added to the TODO.

Hello again, Please add the updated LZ4 r129 as we discussed in a previous post. Just wanted to tack it here for the official to do list.

Thank you again,
Tom

I just released the new quickbms.

[eri619]

Could you add the compression algorithm for yukes.bms(BPE/Byte Pair Encoding) please?

[aluigi]

If you have the source code of the recompression algorithm yes, otherwise no.

[eri619]

please take a look at this
viewtopic.php?f=13&t=1882
i will soon post the BPE Code.

[aluigi]

That error is caused by the missing algorithm.

Could you add a new decompression algorithm? This one is a variant of LZSS, from Donkey Kong: Tropical Freeze. http://www.metroid2002.com/retromodding ... ompression
Basically all this an updated algorithm but it adds some extra features, including different modes.

I also have an example, if needed: https://www.dropbox.com/s/qem0thhn4q7vm ... e.bin?dl=0
Compressed Size: 0x13E6
Uncompressed Size: 0x145E

Thank you so much!

Added in my TODO list
