Heaven x Inferno (tri-Ace SLZ type 5)

Post by soneek »

The old, and also recent SLZ script for Star Ocean 5 doesn't work on these files. Would someone be able to check out this compression? It looks different than normal ZLIB as specified in the BMS script. I included 3 samples.

It is zlib
try this
offzip.exe -1 -a -z -15 c:\myfile.asf c:\out 0x0

It's deflate, not zlib.
The real problem is being able to identify this different format/variant because there is not a "version" field or something that allows me to use the current slz.bms script.
I will check if a work-around is possible.

I have updated the script but don't expect miracles.
The script old and not compatible with the current quickbms ("MEMORY_FILE" is no longer accepted) so I have updated it to work correctly.
The problem of recognizing the slz files of this game remains and I simply used a constant number found in all the provided samples.
If this number is different the extraction will fail.

I tried both the updated script, and those settings with offzip. They each did the job. Thanks guys!
