@Clyde@mitu thank you for the help i really appreciate the feedback and found a solution that seems to be working. For my computer i use a small booster and so i tried putting it on the 2gb_EXT as a test last night, i just woke up and started using and having my phone as a wifi monitor and so far no disconnects.
I was using 9zip to unzip the image and it wasn't unzipping the entire image file for some reason. Decided to, as an experiment, use winrar instead and I noticed the image file was a different size - I'd not even thought to check this.
I was just trying to point out if you're using a power supply with a detachable USB cable watch your length. I have a few that are 3 meters or 10 feet and the longer they are the more susceptible they will be to undervoltage.
I do like Anker power supplies and it sounds like you have plenty of amperage and it may even be a 5V power supply. The thing is high amperage doesn't mean a smooth 5V delivery. A good power supply will have the "filter" circuitry to deliver clean consistent power as well as under load.
Most of my USB cables are Amazon and I just rely on reviews if it's a decent cable. Just don't buy bottom of the barrel price cables. :)
User error was the problem, (as expected). The thing that broke the dam was figuring out that the input_..._btn entries were for the controls vs. input_...(no _btn) entries. When I looked closer, I figured out I didn't have a complete set of hotkey inputs for the keyboard or the controller in the .../all/retroarch.cfg file.
So that is sorted. I still would like to know the answers to the other questions, but I can live with this.
@Efriim Ive done some overclocking tests with PPSSPP and its core_freq and sdram_freq that make the biggest difference with performance. I ran "top" while running a couple psp games and I never saw the CPU go much above 50% so I dont think overclocking ARM will help.
You don't really explain what's going on, but from what I can see, the display powers up, but you don't get any picture. I'm not sure it's the correct driver board, but if so, do you have to select the input with the side panel that you picked up and put down?
