Thanks for posting it.. The site you linked to had some comments.. Not sure what that site is, so I'll respond here.. The screenshots are of the 2 playing each other...This was meant to be done to show how easy it is to make games multiplayer across platforms.. I meant for the code to be a lot cleaner to show only a few changes are really needed, but as I procrastinated, I had to just hack something together... The psp code is at: psp code The psp stuff should be better.. You can actually configure if you are the client or server and what ip address to go to.. The DS one you are always the client, and your ip is hardcoded.. not hard to add a menu to fix that, but i just dont got the time... Oh and another thing.. this is really thrown together.. it uses udp, with no error checking.. so if you drop a packet, you are forced to execute the ROHPP macro (reach out hand pull plug)
