Issue with sp2 -> spr extraction: Graphics get corrupted in version 3.8

[gosiriman]

Hello,

I am experiencing an issue when extracting .spr files from .sp2 using this tool.

When I extract an .spr file and apply it to version 3.8 (the pre-remaster version), the graphics are completely broken/corrupted in-game.

The graphics look perfectly fine while previewing them in the viewer, so it seems like the problem occurs specifically during the extraction process itself. For comparison, if I extract the same .spr file using the LineageViewer2023 tool and apply it, it works flawlessly.

Are you aware of this issue?

Thank you!

Description

When extracting an .spr file using this tool and applying it to version 3.8 (pre-remaster), the graphics appear completely corrupted.

Expected Behavior

The extracted .spr file should display correctly in version 3.8 without any graphical issues. (Note: Sprites extracted using the LineageViewer2023 tool work perfectly fine).

Actual Behavior

The graphics are heavily distorted/broken when applied to the game. However, the sprites display perfectly fine in your tool's viewer, suggesting the corruption happens during the file extraction process.

Question

Are you currently aware of this extraction issue? Let me know if you need me to provide sample files for testing.

Hey I'm running into the exact same issue with 3.63. Noticed that dimensions of the sprite frames in PakViewer are larger than what they are when I look with older tools like spr2spd, not sure if thats part of the reason. Unfortunately those older tools are very inconsistent.

@gosiriman You mentioned that extracting the same .spr using LineageViewer2023 works correctly. Would you be able to share where to download that? I haven't been able to find it.

Thanks!

OPEN LCX FILE

ALL KEYS FAILED TO DECODE THE LCF ENTRY THE DATA MAY BE CORRUPTED OR THE KEY IS INCORRECT,

The lcf keys is changing pretty quickly, won't be supported since NCSoft will update the key, it's meaningless to do the decrypt things for now.
