As I was modeling a custom case I realised the back IOs would be better lower so I flipped the entire board upside down.
That kind of solved my problem with the whole not having labels at the bottom.
AND it also gives me a bit more room to make a cartridge connector PCB.
Which now got me thinking about how many signals I can/should bring to the cartridge slot.
Because it'd be really easy to set any pins to input mode and drive the video signal from a "SuperFX" cartridge.
We can go feature-creep-stupid with this
Now I just need to cut traces to flip the Player 1 connector and swap P1 & P2 since it's upside down.
Thanks to the gamepad header pins I can rewire this easily.
And put buttons on the underside.
( I miscalculated the size of the connectors, subtracted the diameter rather than the radius, doh! )
I'll post case progress to a different thread. Just wanted to "for the record" in this thread that I wasn't just making random arm-chair backseat-driver suggestions
And while I'm modding that Uzebox I just thought I could dual-color that LED with a 2nd resistor->LED->VCC on the same GPIO.
They'd both always glow a bit (somewhere below 1/4th with the voltage drop) when set to input but that's fine since we'd want it to be always on at least a bit when powered.
For example could do high=green, low=red, input=both faintly on, 50-50 high-low = both half power on, PWM anything in between.
(or other colors, I'd probably do blue-red gotta check if I have any blues in stock)
I wanted to add another color to see when I was writing vs reading the SD card.
