Emulation performance can be highly idiosyncratic depending on the platform and game. Certain features can be more difficult to emulate than others, and there's also the issue where some older cartridge-based platforms make fairly heavy use of coprocessors inside the cartridges.I was completely unaware that the difficulty of ensuring backward compatibility could vary that much from game to game, it's very interesting. Does this mean that some games are particularly demanding in terms of RAM and power, or is that irrelevant?
I really wonder if the job offers posted by NERD about emulation are aimed at NSO or directly at backward compatibility of the current Switch with future hardware.
NERD may be somewhat involved with BC for Switch games, but that's probably going to be more on Nvidia.
