August 28, 20241 yr Hi everyone, i'm trying to translate a Bleach japanese game from PS2, worked on the text routine and now i want to change the font, i don't quite like it and doesn't fit the game IMO. BUT, i can't edit it, tried Console Texture Explorer (Where i can edit 8bpp textures) but 4bpp i can't... anyone knows how can i edit it? font.zip Edited August 28, 20241 yr by wsldecoded
September 4, 20241 yr Yeah, Console Texture Explorer's 4-bpp swizzled format is different than this 4-bpp swizzled format. I think you could export/import it by calling some Python functions in ReverseBox or Noesis's imageUntwiddlePS2. Note, I used the C++ code below to convert it, just because that's what I'm familiar with. Ikskoks also had a list of potential leads here: It appears to have 4 256x256 textures at different offsets (unsure where the pointers are).
