@goroots The RockPro64 provides excellent performance in PSP, N64 and Dreamcast. As Bkg2k wrote above - its (...) "a more powerfull board that can run the PSP and the N64 at full speed".
The Rock64 is approximately on par with the RPI 3, so scale your expectations accordingly.

Just a heads up to those who wish to help test and offer feedback on here.
The RockPro64 image has been labeled release because 1) it tests very well - big performance improvements over beta in Dreamcast, PSP and Nintendo 64 (probably best performance on ARM); 2) We've not had any major complaints, except for some PCIe incompatibility of external NVMe SSDs and other hardware, from many people who tested.
The Rock64 image stays in Beta due to some lingering issues and some missing features (e.g. setting resolution from recalbox config for RA cores, reicast, Mupen and ppsspp) - nothing major.

@diamantis42 I also think that mrfixi2001 baked in that work from Leapo into his image.

Hey @diamantis42, I think that @paradadf is pretty spot-on in his response. I imagine, however, that support for the retroflag cases woulnd't be much of an issue - just a case of implementing the script they require in the the build.

@rocpro Always, do you have a R64 or Pro board ?

@oldgreg Thanks. You need to be a bit careful with those pages comparing boards - I submitted 3 corrections (1x for SOPine, 2x for RockPro64) in the past due to incorrect info.
Then there is question of Linux support for the SOC - which is a whole different story Raw power doesn't matter as much as solid sw support; as things stand it will be a few months before H6 graphics are usable.

@voljega I see The Pine H64 is a pretty powerful board (somewhere halfways between the Rock64 and RockPro64), but it will be many months before its in a software shape to play games.

Meanwhile, the newest Rock64 image is pretty d**n good performance-wise even without overclocking. A new Pro build is coming too.

@voljega I am a bit confused with your comment - what do you mean ?
