[Synopsis]

In this video, I am testing a Banana Pi M2 Zero with the Retro Orange Pi O.S. to see how well it runs Neogeo games. To my surprise, it ran most ROMS very well. The Banana Pi M2 Zero is about the size of Raspberry Pi Zero/Raspberry Pi Zero W, but it has a powerful quad-core CPU vs. the Raspberry Pi Zero's single core CPU.

I tested a number of different Neogeo BIOS, and I pretty much got the same result. I couldn't run any more roms using different BIOS sets, and it isn't always possible to run every ROM successfully. It happens for all emulators, you have a number ROMS that simply don't run for whatever reason. It could be a problem with the emulator, or it could be a problem with the ROMS. It is what it is, but more ROMS worked this time around compared to the last test.

I used a small desktop fan with a heat sink on my Banana Pi M2 Zero board to cool it down. As a result, the temperature stayed around 38 ° C to 49 ° C (100 ° F to 120 ° F). As a result there was no throttling, and ran pretty smoothly. The heat sink isn't enough to cool the CPU on this board, and the temperatures can get as high as 70 ° C ( 158 ° F). High temps reduce the life of any CPU, and this is why modern CPUs have heatsinks with fans on em. Some CPU heatsink fans even have heat pipes to cool the CPU more effectively.

This is for CISC(Complex Instruction Set Computing) processors, not RISC(Reduced Instruction Set Computing) processors. The Banana Pi M2 Zero's processor is a Allwinner H2+ quad core Cortex A7 which was developed from a ARM based RISC architecture. For some reason, it runs very hot. If you run games on it then it gets even hotter. This holds true for other ARM based processors as well. RISC processors use a method to reduce power usage by using simple set of instructions to make calculations. CISC processors can make computations using complex instruction sets, so CISC instruction sets have variable lengths. The length of the instructions can be very long, or very small. RISC processors have fixed lengths, so in order to solve more complicated computation. It must break it down into many sets, while CISC can do it in less cycles.

As for the Allwinner H2+ quad core Cortex A7, it seems to be over clocked, and heat is a real issue with it. Never the less, in these set of tests, it ran very well.
