how to use tailfin?

hi guys this is my first time actually posting on reddit sorry if the formatting is weird.

i got tailfin last night and ive tried to play a few different games but every time the screen stays dark? (i have tried waiting a while to see if it just needs time to load up).

i am pretty new to emulating, i usually use manic or delta and they work fine so i can’t figure out what im doing wrong. can anybody help me 🥲

i get my roms from romsfun btw if thats relevant
