Some g00images can not be previewed

For example __g00_card_0400210_full_yuge_01.pck __g00_card_0400210_ful.pck

Is it possible to see this g00image?

These are not all transparent

@LaplacesR This repo's only job is to unpack the .pck files and .pck file is only a set of any type of files. And, last month some guys found this problem and till this post, no solution. In fact a man familiar with ARM/x86 can work out this in a shout time.

These some known issue:

  1. There are 3 common types of g00 image in the past Siglus/Reallive Engine, with the sign(first byte) 00~02, but the new type above has the sign 03. And we can easily find source code of old type g00 en/decoder.
  2. I found that in the binary file of RewriteIM it redirect type 03 to 00, but all the tools I found can't read the new type g00 that I simply rewrite it's sign.

(It's better to open another issue so that I can close this one with the solution of question.

Scene.pck in RewriteIM is similar to the one in SiglusEngine(Rewrite Visual novel), so we can use the same tool chain. See https://github.com/number201724/SiglusEngine/tree/master/russa_rewrite_tool

dump Gameexe.dat with decryptdat.exe dump Sence.pck with parsepck.exe
