    Hacking Retroarch Wii U, devkitpro r38 and WUT

    Thanks for resharing the pastebin ! I'll share the following zeropaste of the "git log -u 1 " so folks can get a sense of the scope of work. If you blur your eyes and scroll, you can see the pattern. 1. GX2 & GX2 shaders - a LOT of unnecessary code if WUT GX2 headers are updated 2...

    Hacking Retroarch Wii U, devkitpro r38 and WUT

    I plan to have some time in January 2022 to revisit this. This was the second pass. I think I identified the main pitfalls that need to be solved. There are 3 themes that ideally should be done first, but once done, the port should be "easy" and clean. 1. Missing WUT stuff - A handful of...

    Hacking Retroarch Wii U, devkitpro r38 and WUT

    Docker is definitely one good option. For those who want to just build cores, I would recommend that. My interest is a bit different though. Docker is required today, because Retroarch is built on a 2017-ish toolchain that is no longer supported by the toolchain owners. While the base port...

    Hacking Retroarch Wii U, devkitpro r38 and WUT

    Update on WUT binding conversion: I modified the retroarch wiiu code to depend on devkitpro and wut headers rather than the older dependency headers shipped with retroarch. File list of changes: pastebin dot com jgvsXF0v (excluding "deleted" files I temporarily moved out of the way) The Good...

    Hacking Retroarch Wii U, devkitpro r38 and WUT

    Another update: I tried the retroarch binaries I linked a few days ago. I see some obvious runtime errors and nonsensical function names per objdump. Looks like I need to take the time to update (or port) retroach, HBL libraries and deps to point to the wut includes/libs. This is because wiiu...

    Hacking Retroarch Wii U, devkitpro r38 and WUT

    Further update: I got the main retroarch_wii.elf and rpx linked using the DKP ppc r39 plus wut package tools chain. For classes using externs provided by the linker script, I had to comment out exception handling for now, but I think the section name used by hbl is right. I'll follow up with...

    Hacking Retroarch Wii U, devkitpro r38 and WUT

    Quick Update: I revisited building on dkp r39 with WUT toolchain this weekend, with a goal of updating retroarch wiiu to use modern supported compilers and toolchains. The Good: I made the modifications for the .o's to compile with dkp ppc r39 and wut dependencies. The Bad: I ran into issues...

    Hacking Retroarch Wii U, devkitpro r38 and WUT

    Hi @ploggy and @QuarkTheAwesome. Catching up on recent comments, it sounds like the effort is worthwhile and doable. I'll have some time to revisit Wup & devkitpro modernization later this month (July 2021). I'd like to coordinate with the right folks. Is the best way to reach everyone...

    Hacking Retroarch Wii U, devkitpro r38 and WUT

    Yes, but I probably cannot revisit this until after July. Come to think of it, I do have one question. How do you launch a WiiU executable with command line args? I'm asking because I recall building a stock ffmpeg ffplay executable for WiiU with SDL support, but I had no way to test it...

    Hacking Retroarch Wii U, devkitpro r38 and WUT

    Another quick update on options needed to build retroarch with WUT, devkitpro r38 and portlibs. When it comes time to integrate, these WUT options will be required wherever we run the linker. -L/opt/devkitpro/wut/lib -lwut libwut deprecates a bunch of older libraries like libcoreinit, so...

    Hacking Retroarch Wii U, devkitpro r38 and WUT

    Per WUT - I'll take a look later this week. I didn't know upgrading to r38 could actually address issues, so that's good news. Per ffmpeg - yes. I fact, compiling the ffmpeg core was my original motivation for using the latest, stable DevkitproPPC release. I'll take a look tonight to see how...

    Hacking Retroarch Wii U, devkitpro r38 and WUT

    @mive / @ploggy - gotcha. Confirmed the nightly and my local build are teh same - individual core rpx's seem to work well, just not the main frontend rpx. Thanks for all the help thus far. Quick status: The builds using devkitpro r38 from pacman with portlibs appear to have feature parity...

    Hacking Retroarch Wii U, devkitpro r38 and WUT

    I literally just tested nightly and repro'd this. If only I'd been a little more lazy. Good news I guess? :) I'll follow your advice and build the older release.

    Hacking Retroarch Wii U, devkitpro r38 and WUT

    Not so great news. Launching the newly built retroarch.rpx resulted in the error "There is a problem with system memory". For now, I am ignoring the cores, and just attempting successfully load the retroarch.rpx frontend. Other retroarch posts imply this is a runtime memory size issue. If so...

    Hacking Retroarch Wii U, devkitpro r38 and WUT

    @QuarkTheAwesome and @mive Thanks! So simple. The entire build works for me with default configs. To make sure this is reproducible, I'm going to nuke my setup and start from scratch. Afterwards, I'll test a few rpx's before messing with wut changes. Steps to rebuild 1. GITHUBCOM = github...
