Thanks nitrogen_widget & ZeroQI, can be posible the use of AM, when it comes to China, Orange Pi Plus 2 (not opi2plus), I will try to compile because as I said before, I have perfectly configured in one of the microsd AM + emulators (only i used AM cards, When all is configured not need more emulationstation, or this is that i think).
For other side, banana m3 and x4 are more powerfull than raspberry 3 and than Orange Plus 2 (orange pi plus 2e its the board i ordened), the use of i do from the board, ITS near of pc (with gimp, inkscape, any games (for esta am), office suite, and see video (not 4k or 1080, its well 720), i need any very small (front of my expensive laptop and weighs about 3 or 4 kg
The reason for i select orange its price, and the more than one 1gb ram raspberry.
The two boards that you have said, are very good indeed for emulation can be perfect, because I think that could move almost the entire catalog of PSP and many games saturn in yabause (in android it is able to move many games to fullspeed machines with similar power to banana m3).
On youtube you can see several videos of Banana m3 ppsspp moving, even x4 is moving in lakka Final Fantasy Crisis Core on a large TV.
For other side, banana m3 and x4 are more powerfull than raspberry 3 and than Orange Plus 2 (orange pi plus 2e its the board i ordened), the use of i do from the board, ITS near of pc (with gimp, inkscape, any games (for esta am), office suite, and see video (not 4k or 1080, its well 720)
If I were looking for something to play alone, I stay with one of those two options: x4 or banana m3, (would have to look at the community support and ongoing projects, as this is as important as power), but at this time I needed something cheap and more ram a raspberry (if raspberry came with 2 gb of ram, the had chosen as the great community behind this device, the support given to each project and that there is always someone willing to help it is one of its greatest strengths, rather than its power or its price, but in this case I had to choose a power-price).
Sorry for my bad English
P.D.: i cant wait to try with compile AM
