It’s safe ,and I could confirm that . I play Monsterhunter , and turn on “60fps” cheats , so far I have played for 2 years . Don’t worry.
But it’s just safe for Room Based game , like diablo/ monster hunter
I'm using emuiibo 0.5 release ( I compiled it myself) , and copied ACNH Amiibos to SD card , I could read that emuiibo covert the raw bin file , but the amiibo couldnt show in the game ...
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
