You are my hero, eule... Didn't notice the "patch to add themes" button in the HXF Editor. LOL!
a) modify the boot screen - done
b) change the /a folder to my own theme - done
c) run Date Patcher so device will install new firmware - done and pretty!
d) change the menu text because "3D game" and "Interesting game" are kinda stupid titles
____ - Okay, now the HXF contains proper English.
However, since I already used the date patcher on the HXF it's saying "same firmware version"; won't update with the changes!
I did set the computer's clock ahead a day then try a patch but that didn't fix.
Suggestions? Some line to modify in the HXF?[minutes later]
Downgrade to 1.20-dof HXF then reinstall of modded 1.22 HXF fixed issue.
