TIM image not found in file

Environment

jPSXdec version: v1.00 Operating system: MacOS Java runtime environment : java version "1.8.0_111" Java(TM) SE Runtime Environment (build 1.8.0_111-b14) Java HotSpot(TM) 64-Bit Server VM (build 25.111-b14, mixed mode)

PlayStation Game (if applicable)

Name: Matsumoto Leiji 999 \~Story of Galaxy Express\~ Region code (e.g. SLUS-1234): SLPS-03220 & SLPS-03221

Description

What were you doing?: Extracting images from some .DB2 files.

What happened?: I managed to reverse engineering the way the assets are concatenated together into .BD2 archives. On one file (DAT/BSTAGE.BD2), there is an image at the beginning that is not found by jpsxdec.

I can give you more details like the offset of where the TIM file starts and its length. I suspect this image to have many palettes.

All the other images were able to be extracted as expected by jpsxdec.

What was or was not supposed to happen?: This image should be extracted like the other ones.

Hi, yes the Tim start and length would definitely be helpful.

Here are the details:

file: DAT/BSTAGE.BD2
offset: 19104,
size: 32360,

When decrypted with another tool, this image is 252 x 253 and here's what it looks like with the 1st palette (it's a texture for one of the levels):

Hopefully this is fixed in today's release. Let me know if you experience any more issues.
