Help to view/edit the font0.bin file of You-Gi-Oh Duel Monsters (PS2)

[Alpha 1001]

Hello everyone, someone can help me to view/export the attached file to a common format as the png? This file is the font (glyphs) of Yu-Gi-Oh Duel Monsters GX Tag Force Evolution (PS2 release). It seems this font is compressed, this game has others compressed files, there is some tools to edit the others files, but there's no tool to edit the font. Thanks in advance!

I concur some variable length compression is likely, seeing patterns like this, making the compressed files part of this forum appropriate for that (these wavy artifacts are often indicative):

Though, I also see some uncompressed glyphs in the file, like Hiragana gu and ke:

Some observations that may help you and/or others figure it out:

- 0..4468h - 8-byte records, presumably containing glyph offset, size, and format info

- 4468h..7AD0 - variable size glyphs probably compressed

- 7AD0..11BA4 - 4bpp uncompressed variable size glyphs

- 11BA4.. - variable size glyphs probably compressed

There is a tool to dump files EHP archives used by this game, many dumped files I can make the decompression using the WinRAR. I tried to attach a header used by zip format to try decompress this font, but the WinRAR says "The file is corrupted". Maybe the compression algorithm is Deflate.

Those might be informative then.
