I opened up the rom in Tile Molester, found the kanji section and used the paint bucket to replace colours until the kanji were recognizable. Here's an example of the in-game kanji:
Originally something like this in Tile Molester:
Replaced colours, Row Interleaved mode:
The kanji clearly have parts missing on the right side. 宝 矢 六 論 四 五 雷 for example are all in there but their right sides have been cut off. I thought in order to make the table file I would just have to find the letter offsets in an image editor then type them all up, but this is making things more complicated. Can anyone help me?
