Compiling snes9xgx-4.4.8 with matguitarist's modded libogc for 3rd party controllers

[arthurfreitas96]

Hello, I bought a 3rd party Wii Classic Controller Pro that is giving me very laggy output in the current version of snes9xgx (in wii games and gc games the controller works fine). I found a youtuber reviewing an off-brand controller (not the Pro though) and experiencing the same, here: https://www.youtube.com/watch?v=P9b4ZtHvlLs&t=420s

I tested older versions of the emulator but the only one that solved my problem was the patch mentioned in this post: https://gbatemp.net/threads/latest-emulator-and-libogc-with-3rd-party-classic-controller.217245/

However, matguitarist made his patch using snes9xgx version 4.3.2 and I wanted to compile the current version (4.4.8) using matguitarist's modded libogc and and portlibs folders and this is the first time that I try to compile this emulator. I'm using devkitpro pacman and in devkitpro's folder, I replaced libogc and portlibs folders with the modded ones. Then, after getting some problems compiling the snes9xgx's source code, I started using devkitPPC r29-1. I also installed the following packages: ppc-bzip2 ppc-freetype ppc-libjpeg-turbo ppc-libogg ppc-libpng ppc-libvorbisidec ppc-mpg123 ppc-mxml ppc-pkg-config ppc-zlib

When I try to compile the source code I get:

What am I missing? Thank you in advance.

Yeah you're trying to mix and match. that usually doesn't work out very well.

I've written a fix of my own, can you try it out? snes9xgx-wii.zip

[arthurfreitas96]

Just tried it and its working. Problem solved. What was causing it? Its possible to keep this fix in future releases? And thank tou very much for your help.

Looks like when I fixed 3rd party controllers 10 years ago there still remained a group of them that don't send back calibration data and wiiuse would continue forever trying to retrieve it. I coded a fix and I've made a PR to libogc.

It's frustrating that people (in this case matguitarist) don't submit these fixes upstream and instead compile and distribute forked code.
