How does one update the bios?
I bought this off @Derick2k about 8 months ago so I’m still getting up to speed. All I know about it is what it says off the right of the cart Custom SH-2 + Super BIOS.
He said @Mitsurugi-w did the cart for him.
If it’s easy to upgrade the bios, I’ll do it. Otherwise, ultrasimms it is ugh
