Tons of Indie developers, even Japanese ones have a decent track record of getting it right when it comes to the basics. (And look Agatsuma got the framerate and performance right. But messed up just about everything else)
Bamco and the likes of Koei (Who started out in the PC business and has been making PC ports of various kinds for well over a decade with the warriors games. That were not very common releases until the last few years) get zero leeway from me. They should know better by now. Especially at least when it comes to resolution. They are painting themselves into a corner by not offering arbitrary resolution support for at least the single AR the game is designed with. It's not forward thinking. (Especially so when you add in the lack of care for proper AA put into any of these games)
Bamco also has been porting various games to PCs for over almost 15 years now. Pac-Man World 2 came out in 2002. Pac-Man World Rally came out in 2005 and has no problems supporting resolutions like 1080p or 60FPS

I don't know whether PMW 2 or 3 run at 60FPS though. I don't have them. It'd be interesting to see.
It's 2015, there is no reason to be developing for the PC platform, releasing on Steam and living in this bubble. Japanese or not.
That's the problem, is that the scaling needs to be handled delicately on both. More so on the SNES because of the non-square PAR.
Blurry bilinear crap we do not need.
