So, does this mean that there are no non-ASM ways to even find a table for a WS/WSC game? O.o

Depends on the game, JCE3000GT and I had absolutely no problems making a table for (And finding text in) FF4 back when we were planning on translating it. |

And what ancient chinese secret did you use to find the table for that (seeing as thats a WSC game, and I couldn't even find the FONT in a WSC game, let alone the table values... >.<)?

Well, if it's of any help to those willing to offer their help or advice, the game in question is Shinseiki (or Neon Genesis, it depends on where you look as to how the title is listed) Evangelion: Shito Ikusei (isn't that great? My spell checker hates all four of those words), and it would appear that absolutely none of the graphics in the game are compressed. I recall going through them some time ago, being able to recognize cut up and tiled bits of "cutscene" images, forms of Angels you can raise (contrary to the first post, the game is a life-sim type), rooms you can explore, menus, title graphics, font, everything. I suppose it just confuses me a little as to why only one part of it all would be compressed, but then, I am mostly a graphics person, not much of a romhacker.
Sorry for my long-winded and probably ultimately useless post, I'm a little scatterbrained today. I just wanted to try to get what I know about the game known to others.

As I said, it depends on the game. FF4 stored its font in "Genesis" format and the table was easily built from looking at that. |

Use subpar oswan-tracer.
Hit '.' at some dialogue to dump RAM.
Open 'ram.bin' @ $2500 with 2-bpp planar (Gameboy = WS).
You'll see some top-bottom tiles.
Quit emulator.
Place a 'hook_wr 0 2500 2600' to log writes to RAM $2500-2600 (current tile cache).
Before the dialogue runs, hit '/' and ',' to activate tracing, memory.
Play until that screen.
This shows up:
[4:1477] W08 = 01 [R-0250D]
[4:147a] W08 = f0 [R-0252D]
4:1477 = Memory map address
Our trace file shows us this:

There might be some header bytes.
You'll have to check for scripting codes.
