I know it's a little bit of an old thread, but grabbed out the PS2 last night and had a few games.
Star Wars: The Clone Wars
Star Wars Episode III: Revenge of the Sith
Star Wars: The Clone Wars: Republic Heroes
All got a work out, what good/fun games.
Astro Boy didn't work, not sure why though.
Was that a side scrolling beat em up?
Pretty much aha.
I did have it on GBA and I still have the XBOX game...waiting for it to become backwards compat with the XB1
Here is some gameplay of it on YT ; https://youtu.be/_Rr0Dt0Cprs?t=387
