Please note that Mesen2 currently appears to be broken on Wayland with hardware acceleration (most things render fine, but the main window is blank during gameplay).

To fix: either unset SDL_VIDEODRIVER (or set it back to x11), or enable the software renderer (Settings > Video > Advanced).

My only source was IRC comments about how .NET makes non-standard use of ELF structures.

As for package behavior, building with !strip debug causes the binary to be about 32MB smaller, and corrupt.

Thanks for the swift fix.

@kode54: Huh. Do you have a source for that?

I've pushed a new pkgrel that disables !debug.

The package needs !debug as well, as debug still manages to break this package. Thanks, Microsoft, for your ELF breakage.

@xiota, well, i switched to sway a couple of months ago, but i'm still having the same issue. maybe wayland's the culprit? too lazy to setup an xorg environment to test...

@red_M95 Would you happen to be using kwin?

@ISSOtm, it looks like i can't open an issue for mesen2 on the github at all, so i dunno how i can report that to sour...

Hello all,

Turns out a problem with my email setup meant I wasn't getting notifications about this package. First oops.

Then, I had indeed missed a build-time dep on zip. Second oops.

And finally, that should have been caught by the CI script that builds from a clean chroot... except I forgot to enable it. Third oops.

My apologies for the triple mess-up, but I hope these issues will be resolved for everyone! And thank you for your patience.

@red_M95: That sounds like an upstream issue, can you try reporting it to Sour?

Hey, you are missing a makedepends(). Mesen2 requires zip to build, so I have attached a diff file to show what you need to change to get this package building again.
