LCSC has USB3 but nothing 90 degree

Forward Voltage is: 2.2V (as usual) if I calculate this with 200R and 3.3 I'm getting 5.5mA ....
For 20mA it should be 56R and for 3mA Leds it should be about 390R ....
For sure its not needed to go for the full 20mA .... but wouldn't a value of 100R (11mA) more suitable?
External LEDs need to use resistors externally together with LEDs depending on supplied voltage.
For example A1200 LEDs are double LEDs and may require 5V with specific resistors to work.
A600 LEDs are single LEDs and should be powered by 3.3V. You can check the A600 LED board - it may include resistors already - though they are for 5V.
You also need to check how those LEDs are soldered. A1200/A600 use common cathode while MiSTer requires common anode. So you just need to desolder the LEDs and solder back in opposite direction.

It's not about voltage. Resistors limit the current on LEDs. Without resistors current will be too high. You may fry either LED or FPGA chip! Even if it looks like working - it may damage both components in long usage.
A600 doesn't use 3.3V. It's 5V computer.
I suggest to use at least 200 Ohm resistors.

You've asked about time out in released cores - i've said there is no timeouts there.
Compilation and licenses are completely different things. End user should not worry about this.
