Found some footage, looks like it will have text rather than images with text in them (common in puzzle games and other low text affairs, especially on older systems).
For others reading
Anyway .tbl files are custom for each game, though some may share aspects. You will tend not to find them premade for anything other than pokemon and things with existing text editors for the game as most would consider it if not easy then a fundamental part of making a hack and a .tbl might just save someone that can make use of it a few minutes in making it.
The link in my signature (
http://gbatemp.net/threads/gbatemp-rom-hacking-documentation-project-new-2016-edition-out.73394/ ) covers a variety of methods of finding out text encodings, a handful are specific to the GBA or DS and some are not that suited to Japanese or Chinese but most apply to any system you are looking at.
If you are just learning about this sort of thing I should say that jumping right into a bit GBC RPG is quite ambitious.
