Azure Striker Gunvolt 1, 2 and Luminous Avenger IX Sprite Rips

[Deep Weeb]

@RTB You are right! Blaster Master Zero also uses IRARC/IRLST format, so the script also works. That makes it 5 games now.



However, unlike Gunvolt, most of the sprites in BMZ have an extra 'TLPI' section, and the texture is incorrectly converted. I have no idea how to fix them.

@HellZero Step-by-step on how to use my scripts to rip and reassemble the sprites:

Step 1) Get PHP 7.0+ from its official site. You'll only need 3 files from the archive, "php.exe", "php7ts.dll", and "php.ini" (renamed from "php.ini-development"). My scripts doesn't need any PHP extensions.

Step 2) Download my GitHub repo. You'll only need "psxtools" folder under "tools/psxtools".

Step 3) Open cmd.exe (windows command line), run this on a IRLST file. Like the BMS before, it will extract and decompress the files to a new folder.

Code:

php.exe  psxtools/pc_gunvolt_irlst-irarc.php  FILE.irlst

Step 4) You'll be interested in the extracted .17 and .7 files. Run this to generate the QUAD and texture file from the attachment on the post before.

Code:

php.exe  psxtools/quad_pc_gunvolt_IOBJ.php  -gv/-gv2/gva/-mgv  FILE.17
-gv  = Azure Striker Gunvolt IDTAG
-gv2 = Azure Striker Gunvolt 2 IDTAG
-gva = Gunvolt Chronicles Luminous Avenger iX IDTAG
-mgv = Mighty Gunvolt IDTAG

NOTE: The script only works for files that has 'IOBJ' string in them.

Step 5) If you want to open with quad player, skip this step. If not, run this to render all assembled sprites as individual frames.

Code:

php.exe  psxtools/quad_render.php  FILE.quad

Step 6) As I do not use any image library, those CLUT and RGBA files are actually raw pixel data. You can convert them into PNG by running:

Code:

php.exe  psxtools/clut2png.php  FILE.clut
php.exe  psxtools/clut2png.php  FILE.rgba

From here, you can make a sprite sheet from the resulted PNG.

You can also refer to the source code to understand how I do it.

Hope that helps!

Any way to do steps 4 and 6 in a batch? It's kinda cumbersome to do each one by one. 

Also when trying to decompress GV2's "cmn_demo.irlst" (where I assume cutscenes are being stored) it will get the following error message

Code:

PHP Fatal error:  Allowed memory size of 134217728 bytes exhausted (tried to allocate 8388616 bytes)
