The charger just states that the batteries are possibly 3s. There's no guarantee of a BMS board, 3s charge board internally mounted or what the input is actually capable of. Which means based on the brick you need a 12.6v 3a constant current constant voltage charge setup to be safe. Those items...
The power banks you're looking at here are 12v output they could be likely to cause a fire connecting to your charge input.
In the case of your portable the internals are unknown to the forum and the power circuit would also be unknown. That being said it would be difficult then to reliably...
I suppose it should be clarified this portable sounds like a 3s lithium setup, that 12.6v charger is likely a dedicated lithium bat charger. 3.7v X 3 is a nominal 11.1v but max charge at 4.2 per cell is 12.6v.
Can’t say it’ll be the issue but the ed64plus has a trick to swap something to do with pal and ntsc says on the back of the cartridge, couldn’t hurt to see if that’s an issue
Well I suppose I can go ahead with a cartridge slot now, I have something that actually test printed ok and is pretty solid. Took a few tries but it’s there
Are you using a pal console? Not sure if that makes a difference with the driver board. Do you have your wires shielded like twisted pairs for rgb and composite? H/V sync shouldn’t be twisted
Just wondering does the Wii in the ashida have 1.6 installed or potentially an earlier version? I could see having an earlier version of rvloader being installed and needing the reinstall to update with version 1.6 being a potential fix. 1.6 needed a full reinstall to update with the sandisk...
Give swaping from composite to vga a test, I get a weird issue on one of those 5” lcds and the black driver board vga looks messed up on boot but swapping inputs cleans it up
