Has anyone gotten Doom Tournament to work on GZ 4.13.2?

[ichxg0]

I'm trying to run flak_m.pk3, an Unreal Tournament weapons mod. It looks nice, there are two expansions for it as well, but I'm getting error codes trying to run it in GZDoom 4.13.2; I looked inside and saw that the zscript was for an older version though. I tried downloading 4.3, the version it indicated and it indeed functions properly... However this was on a windows build through a VM, as I have an Apple Silicon MacBook; and that's not gonna work. Even if I got decent performance there is still a large input lag, so nah.. Unfortunately the intel version for Mac will not run on my machine, so I'm left with few options...

So, are there any methods or even patches you can use/make to run older zscript stuff? Seems weird to me that it could be so outdated as to be incompatible but what do I know. Anybody got any tips?
