I think you have to try harder.
hat I mean is - you said you don't know what's in the files. Come on man - your brain has to be worth more than that! Examples:
- some files/directories start with "CG" - this screams "Computer Graphics". Open them with TiledGGD and - hey! These are images indeed!
- some files have "BGM" in their names - could they be background music?
It's important to try and understand what's where, because text is sometimes a little tougher to find than other data ('cause you have to run these searches you talked about in many files). So finding "where not to search" is useful. You can concentrate elsewhere with that.
So here's a little push forward. Now you do the work.
- root contains SJIS quick text for description of the game (adventure+simulation)
- CG contains images with backgrounds (one with embedded Jap text) -
=> expect each ".b" file to contain 32 bits per pixel graphics
- SCG0 contains chapter title screens (with text as graphics)
- SCGR contains short text in graphics (anything like "the end" or something?)
- SCGQ contains graphics again, but with KCT extension (probably animated graphics, like FLC)
- SCG* contain other graphics
- root KCT's seem of different types:
xxxx (numbers) look like graphics as part of animations
BGM* should be background music, obviously, but not sure of the format
IDOU, KABE, LOAD = graphics (not sure if it's an animated thing)
LOD01, LOD03 = graphics "now loading"
MEM* = image with some kind of warning about the RAM (and text)
OMAKE= (160 pixels wide) image without text
TITLE, OPTION, SAVE = background for these menus?
SOUKAN contains a few big characters in image (to be translated)
Missing bits to be explored:
- SIN files = ? (one of them is called story, you should check there!)
- ACM files = ? (that's a standard for audio but Format factory & VLC won't play these)
- AC2 files = ?
- BIN files = anything, you should check these too
- DAT files = same as bin files, though the names have meanings (ex: LOGO does not sound too text-y, does it?)
- WATASLABS = ?
