The extended discussion is due to a (non-regression) bug which has now also been fixed in the PR. Suggestion: merge
https://github.com/NixOS/nixpkgs/pull/251772
Would be important as it fixes a few issues through the new releases

Blackvoxel, a 3D sandbox game focused on automation
Rather simple mkDerivation, I’m just unsure if the desktop item works properly.

Xash3D
A game engine reimplemention GoldSrc. mkDerivation stuff, rather convoluted. It’s all proprietary games, so you need proprietary assets to run it. You can still build it without assets though.
It has been approved by one person and I haven’t seen any rebuttal since a while.

mkDerivation, one person approved it (me). Needs assets to run but you can still build it without assets.

wipeout-rewrite
Another proprietary games which needs assets to run. That one is stalling hard. It’s been approved by one person already. I’ve also left one small remark but it should not stop this from being merged.

update to sm64ex, one approval from me, there’s still an open question about whether the commits are properly organized but otherwise it works.
