Castlevania 3 is one of the most advanced games on the system; I wouldn't expect that to be up next.
So what exactly did they do with this one? Music synthesized with higher quality instrument samples? Carefully-selected clips from the cartoon...
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
