It really makes the screen harder to see, I used loca also. IPS is better or no light.
the front light I ordered was delivered in a very timely manner despite the current covid complications. when I last-minutely decided I wanted a backlight instead, the product return was handled promptly and smoothly.
I like the texture effect on the frontlight, but it seems to have some problems with my GBA (some games crash from time to time). Maybe my install but I followed the guide from TDNC on youtube which is pretty great
I did this as my first soldering job and was successful! I'd recommend this mod to anyone wanting to light up their GBA screen without paying $50+ for a fancy back lit LCD. I also used LOCA for a better display, which was surprisingly not that bad to do.
Failure on my part
