I use modrinth launcher normally can I use it for 1.16.1 rsg

i don't think so, as far as i know, you can only use default and multimc

i don't believe so, however, multimc is just the best launcher anyways.

i suggest watching oshgay's minecraft speedrunning setup tutorial on youtube, follow their instructions and youre good :)

to my knowledge, you can use any launcher as long as the mods you have enabled are allowed

if it helps theres a premade modpack on modrinth called "SpeedrunPack" that has all the allowed mods for speedrunning

I checked, you can only use: MultiMC/Prism and default launcher

^ yes
