Best Compression Methods for 'Specific' Games. Q&A

[Masquerade]

Don't use delta, it will only harm your ratio. Not useful since many years (if ever).

SREP 3.2 is always a good shout for especially buggy data too.

i normally use srep_3.92.exe -m5f -l128 -c64 $$arcdatafile$$.tmp $$arcpackedfile$$.tmp for srep but recently have been getting a lots of error: general (de)compression error in srep. and all those were unity games. it fixes if i remove -l128 and -c64 parameters. what could be the reason here ?

Not exactly. There are data samples which give better compression with delta. They are very rare and usually are found in obscure game engines, but still.

Finally taking a crack at Red Dead Redemption 2 (version 1.0.1491.50), but I've been pretty disappointed with initial results

~108 GiB (MP assets ripped) -> ~76 GiB, using oo2core_5_win64.dll with the following MD5 hash

f60dd417457e2ec9be4b28242878dbc1

I did some initial digging on the AES encryption of the "*.rpf" archives, but haven't been able to find any community tools, outside of OpenIV (closed-source, no CLI functionality to decrypt multiple archives), SparkIV (only supports GTA IV), or CodeWalker (GTA V mapping utility), that support decryption and encryption of said archives. I've reached out to multiple members of the developer team but have been met with silence. Researching prior RAGE Engine titles, of note is "Grand Theft Auto V", found a toolkit that shows promise, found here, which supports said cryptography. Very loose *maybe* here, but reading through this forum thread has given me some guidance with a starting point for dumping the AES key for RDR2, of course the methodology will likely not be identical, but it's something.

I'm hopeful that since the RPF versions between GTA V (Version 7) & RDR2 (Version 8) are quite close, I might be able to jury-rig something together.
