I played the entirety of chapter 1 on ryujinx and finally got passed the marriage scene. Note to all users, refrain from playing this game on yuzu and opt for ryujinx instead.
Unfortunately, 1.0.2 does not fix the marrage crash issue. I am unsure what actually causes this and it seems this problem is universal between both emulators and actual hardware. This seems to effect a handful of people too...
I personally have tried playing that scene without the 1.0.1 update and without. I do know that a 1.0.2 update has come out, but ive yet to find it anywhere
I've been troubleshooting for a couple of days now and ive seen the marriage cutscene around a million times at this point. There must be something I'm doing wrong somewhere
I may try the new ram site, and download more RAM to my Switch. Not sure if ddr3 is the right ram
for it tho. Edit- no it uses floppy Ram, just like @AncientBoi
