Changelog

0.2.1

Realized I might have to update this when it suddenly started crashing after I updated my firmware to 12.1.0 from like 9 or 10.something for Skyward Sword. Might do the same for Mandelbrot Set Viewer.

0.2.0

I added stripes. You can toggle them by pressing d-pad left and d-pad right at the same time. The stripes also scroll along the screen. You can't control/toggle the scrolling... yet. Also cleaned up my spaghetti code a teeny tiny little bit.

Realized I had resetting color brightness to full mapped to clicking joystick left/right instead of d-pad left/right. Whoops. That's fixed now.

0.1.1

Just a very basic edit of switchbrew's simplegfx example.

I put a limit on how many colors you can use, should top out at 50 colors. I have not tested this.
I also learned how to edit the makefile to customize the icon and metadata. In a previous version, I used NRO Asset Editor for this purpose.
Generic color list is back to {Black, Red, Yellow, Green, Cyan, Blue, Magenta, White}.

v0.1.0

I added support for files, so now you can strobe your own custom colors. If you don't have a colors.txt file, you'll just use a generic list of colors.

v0.0.4

Literally just v0.0.3 but made with updated libnx. This should™ work on 9.0.0.
