Loader question?

[NSX2002]

I've loaded my own code using naplink.
finally got an ethernet adapter and also want use new
loader (ps2link/ps2client).

I want to link PS2 with PC directly.
however is there anything else needed to make them working?
(I mean hub or something like that. )
if nothing needed, what kind of cable should i prepare?
direct one or crossed one?

Thank you in advance.

For PC to PS2 over ethernet, all you need is a crossover cable and a network card in your PC.

P.S. Be mindful that certain In-link versions must be used with certain Pukklink versions. InPulse's website lists the compatible versions.
