Extended Brightness Configuration Request #185

Closed radicalten closed 1 month ago

radicalten commented 1 month ago

Hello, Based on your reply to issue #180 Screen brightness thing : "The new system used in the libn3ds_gfx_lgycap branch uses luminance and requires hardware calibration. Current Luma versions also show luminance if i remember correctly.", is it possible to allow for extended backlight control (increasing the range from the default 16-142 luminance to an extended 1-172 luminance)?

I attempted to do this myself by forking the open_agb_firm repository and making some changes to the libn3ds_gfx_lgycap branch, but I haven't had any success increasing the luminance range yet.

Any help with how to achieve extended luminance would be appreciated.

p.s. Thank you for creating and maintaining this project!

You will have to dump the most up to date of the 2 HWCAL files to /3ds/HWCAL.dat first so the brightness curve matches. Then there is a limit somewhere i have not removed yet if i recall correctly.
