Bugginess drags it down

Love the idea. I’ve been a long time user. Unfortunately the app is buggy. Loading or saving save states freeze/crash the app frequently (like several times in 1 play session). Also weird things like changing the name of the ROM disconnects it from the save files? Overall just feels like it hasn’t been given much love. Have been using same boy for GBA/GBC and enjoying much more. Would love to see delta updated!
