ePSXe64Ubuntu VS crouton

Well, the very first thing to do whenever starting a new project is to figure out the work already done by others. There are plenty of cases of this. Have a look at the open source emulator ePSXeUbuntu or you could look at what others are doing to hack other PSX games like Final Fantasy Tactics. Good luck.

It's a little more than that, they then added subpixel and momentum scrolling support to Chrome that bypasses X11 and does something custom [1]. Integration problems like this one that require a bunch of coordination are harder to do in open source land.

I'm guessing GP means natively, not in a VM. I've been super grateful for the VM-based method, but I still prefer the native experience like that provided by Crouton[1]. With Crouton being "maintenance-only" now I share GP's hope that a similar thing will be possible and easy.

One way to install Crouton

Go to the github of crouton they have instructions there https://github.com/dnschneid/crouton

At any rate, you can try Breath, Crouton, Manjaro... those are three of the distros people have found success with. It all boils down to the specific hardware involved... which we know nothing about since you kept that to yourself.

Post in r/crouton and refer to https://github.com/dnschneid/crouton if you haven't already. However, I think it's fair to say that Crouton is now broken to the point of being effectively dead.
