Thanks for the PR @RainRat, looks good.

@AchilleMorenville @epiette were you guys still working on setting up GitHub Actions to run tests, since we no longer have Travis?

Because this PR includes renamings of defines, which might break some games if the renamings haven't been done consistently across the board, I'm a bit wary of immediately merging this without any CI. If you guys think you might be able to get the GitHub actions correctly set up soonish, and merged into the official repo, I'd rather wait for that.

@RainRat When you sent the PR, we didn't have CI properly running anymore on this branch. Now we do again, but it didn't automatically trigger for your PR. Would you be able to merge our current dev back into your dev branch first? I think that should then likely trigger a CI run here too.
