Not sure about Hotline Miami, but those other two games run absolutely fine on the Pi 3. I was playing Powerstone only the other night funnily enough. Very impressive on the Pi.
Not to be a Pi fanboy (well OK maybe a bit!) but the problem for me with buying these alternative boards is we think we need more power to run emus for N64 and Dreamcast or that that would improve things, but ultimately it won't offer a dramatic improvement to the end user over a Pi 3. N64 is not really a friend of anyone unless you are running GlideN64 on a fairly powerful device and even then it's not that great (trust me I know). I agree GlideN64 is driving N64 emu right now, but you have to realise that it is becoming more demanding as development continues. Going on my own experiences it has had a very chequered history on my Android devices, where it used to run well on a decent spec device (Tegra 4, 2Gb RAM, but now is beginning to show slowdown even on the lower settings and after user amendments to settings. Heck it used to run OK on the Pi 3 when it was Glupen but not really so much now. I assume this will not get easier over time and ever more powerful devices will be needed to run it.
Reicast simply hasn't had an update in many years and is again not really worth changing over from a Pi 3 for. Until this sees a considered update it's again not worth chasing.
Just imho.
