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

[HellZero]

Here is the decompression code, at my GitHub repo:
https://github.com/rufaswan/Web2D_Games/...-irarc.php

I can confirm the code works for 4 games:
- Mighty Gunvolt
- Azure Striker Gunvolt
- Azure Striker Gunvolt 2
- Gunvolt Chronicles Luminous Avenger iX

Now that you mention that it makes sense.

Well to be fair i don't understand "HOW" to use that code.

If you can explain me that, thanks in advance in any case!
