Gamepad compatability

[AlphaWolf]

Hi,
I've been looking to buy some PS1 games to play using PCSX emulator ( Mainly Toy Story 2 and Digimon World 1).
I'm lloking at the following:
PS1 connector to USB : http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&ssPageName=STRK:MEWAX:IT&item=300305046937
and
PS1 controller : http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&ssPageName=STRK:MEWAX:IT&item=370127635202
My question is:
Will these work using PCSX on my Mac?
Thanks
Joe
P.S, sorry if eBay links are banned, I didn't know.
