So I have a Chromebook now and I wanted to see if i could use it for SMB, but running Nestopia tells me that it's only supported for Windows and other stuff. Even Mesen(-S) has the same issue of not running. Does anyone know any good emulators to use?

There are emulators that run on chromebook. I am not aware of any that run on the chromebook AND are allowed for the speedrun leaderboard.

is there any reason for common emulators as nestopia, fceux, mesen, etc. not being functional in chromebooks?

it says something like 'this file is designed for windows software, and is not compatible with your device running chrome OS.' so i think the problem is the operating system being different

oh right that makes sense

ChromeOS is based on Linux, which is supported by some NES emulators. I no longer possess a Chromebook so I have no means of testing this myself, but if you are able to run Linux applications on your Chromebook, then you should be able to run the Linux builds of NES emulators on your device.

ok that might work thanks

edit: ok so i don't actually use linux and i can't find the download link for it ;-;
