I finally learned how to use a debugger enough to uncover the way text was written to the screen in Digimon 02: Tag Tamers and fix it. At least on some of the screens:
|Original Japanese Screen||Translation||Translation - Cleaned Up|
(I even fixed an issue in the original Japanese where the "H:" was partially covered if your health grew above 3 digits)
There's more screens to fix (mostly to fix the cap of 10 letters for the Digimon name), but this was the one thing I didn't know how to do before.
