A quick googling says 50mA max, but I'm not sure that is correct.
https://allpinouts.org/pinouts/conne...k-amiga-9-pin/

I took a peek in the book Abacus Advanced System Programmers Guide for the Amiga (1988) and it says:

The +5 volt line on the two game ports is not connected directly to the Amiga power supply. A current-protection circuit is inserted in these lines which limits the short-term peak current to 700 mA and the operating current to 400 mA. This makes these outputs short-circuit proof. To prevent the voltage on these two +5 volt pins from falling off too much, the current draw on the two ports should not exceed a total of 250 mA. Unfortunately, this protection measure has been omitted from the Amiga 500 and 2000.
