Title: [PRIZM] Font hacks
Post by: flyingfisch on February 11, 2012, 09:49:20 am

Is anyone working on a font hack for the prizm os? Or maybe even allowing users to choose their own font? I personally don't like the default font :)

The fonts are stored in the flash

So I think you have to write the flash, if you want to change them.
That seems to be no problem...technically.
Alas, when developing flash writing routines, the calculator enters a world of hurt, sometimes. :angel:
Unavoidable, due to human failure. :banghead:
Hence you need secure recovery procedures.
As far as I am concerned, I have not started this project for the prizm. Not yet.
But though I walk through the valley of deep darkness, I fear no harm...
up to now I resurrected every single one of my beloved fx-guinea-pigs, which has been killed in action. ;D

Hehe, I haven't completely bricked my prizm testing out flash writing yet. Had a few close calls though :angel:
