Wow, that is awesome!

Is he using it in LuaFX? That way we could maybe exit to the LuaFX menu instead of rebooting....

This piece of code certainly has potential...

Don't use it atm, I messed it quite bit fiddling to search the good sequence
EDIT: found something useful into debugging: INTC.INTEVT seems to be edited for some reasons... We must found why, and avoir this

Spoiler For POST NOT FOUND:

Bump for announcement: The grayscale engine seems to be STABLE! No need to reboot anymore! I need more testing, but I think here we are

PS : 404th post :-°

looks good... why don't you wrap the code in [code ][ /code] tags?

Whoops, I made a little mistake posting: frogotten to take the old post.
Anyway, I'll adapt MonochromeLib to grayscales, GrayscaleLib.
I have already finished the graphics routines, the sprites will come later.

How could I store 3 sprites easily and user-friendly? (dark, light and alpha)

in arrays?

For which project is this? ALso is it for the Algebra FX/Graph 100 series or for the FX-9860G/Graph 85?

Fx, we have already 5 gray mode in afx...
I don't know how? Tiple arrays, one combined array, or a struct
