Hello there,

I'm trying to figure out how to read the format used for Star Ocean Anamnesis assets. I used the BMS script available on aluigi's website but it doesn't seem to work for every ADLD encoded file. I believe the most recent don't work with the current script.

For reference, it's referred as type 7 on the error message. I would be extremely thankful if I could get some help on how to support the new encoding.

A small sample is included in this post.

PS: In addition to that, the file included after decoding should be an ETC2 RGBA encoded image, but I've yet to properly render the image without a huge quality drop. (the ETC2 compression used might be a variant)

File comment: Another variant that produces a different error (expected PACK, got another signature)

The slz.bms script is correct because the SLZ type 7 has never been documented.

In sample2 the decryption fails because the key is guessed and not calculated, therefore exists a very limited amount of slz files on which it may not work probably because it's not compressed.

Long story short: no solution on both.
