Pokefan531 wrote:I wanted to say thanks for adding my GBA color matrix profiles from libretro. Is the gbi using shaders or texture mapping? I plan to update my shaders since I use a lot of tools for color profile a little bit after my release from December. It would be around May.

Pokefan531 wrote:You may know this or not, my forum post has a video explaining the color space, and mention a little about your implementation of color correction. Yours seems great and over time, the psp shader has changed so I want to implement your algorithm as a shader since it does color correction with minimal desaturation. Yours looks right on one game I tested, and it was Mermaid Melody Pichi Pichitto Live Start. The game has the blue colors darken in raw and compared with the anime. I don't have an SD card adapter for GC to capture the screen for comparison.

Pokefan531 wrote:Last question is, does my shader profiles on your homebrew has the gamma retained? My GBA shader has a darken setting at 0.5, which has output gamma at 2.2 and the output gamma affects the color matrix as opposed to input, but 0.5 darken setting is a common standard on a great light on the GBA hardware.

RetroRGB wrote:I was able to try again last night and had some issues. First, I couldn't find the option in Swiss on GBi, only GBi_LL.

RetroRGB wrote:Next, none of the controller modes worked with my controller adapter. To be clear, if I launched the game with all options checked, except the controller modes, my SNES controller would work fine. If I checked it off and selected A, B or C, my controller wouldn't work at all. I'm using the discontinued SNES to GC adapter from RetroUSB, so maybe that's the issue? I can order a Raphnet adapter and see if that fixes it.
