The script I wrote to enable upper and lowercase text shifting works in version 4.5 with a few alterations. Here's how to make it happen.
First you want to pick a spot on your graphics bank for the extra set of characters, and remember to keep it in the same spot on every screen. A good method is to store them in the Path area, as I've done here. Make a note of what address those characters begin at. For paths it begins at #$80. The default text characters are stored beginning at #$C0.
Next, make two new User Variables: capslock and shift (with no capitalization).
Now open doDrawText.asm and find these two lines of code:
CMP #$FF
BNE notEndOfText
Directly above them (and below LDA Temp), paste this in:
Now scroll to the bottom of doDrawText. You'll see a part that says "updateNormalTextCharacter." Directly below that, paste this:
The final step: add "capsOn" below the next three lines, like this:
You should be good to go. Except for finding a satisfying font.
