PSX-SESCENE.COM 에 올라온 글을 보면, 현재 PSP => PS3 로 데이타를 전송하는 것은 구현을 하였으나,
PS3 에서 요청이 올 때 그에 맞는 데이타를 PS3 로 전송을 하는 것이 제대로 동작을 하지 않고 있다고 합니다.

개발자는 이 문제 때문에 거의 100 번 이상 소스 코드를 검토하였으나, 왜 이런 현상이 나오는지 아직 원인을 찾지
못하고 있다고 하네요.

하지만, 정말 거의 거의 완성이 되었다고 합니다.

아래는 원문입니다.

Guys,sorry for my tripplepost....i just try to keep the topic updated...

A guy on IRC (helcar) told me that they thought they where close to finish the port because all they had to do was to the connect_port. Deviante had already the code for this but then Wuepe joined IRC and told him that the code that he had for connect_port doesnt work and that he had try it already.

So in order to proceed he need the fifo (i dont know what this is).

In other words:
They have managed to send the code from the psp to the ps3. The problem is that they cant send the specific code the time the ps3 is asking for it. They have to manage that and then we are ready. Also Deviante said that this problem could be a error in the code he wrote but he looked at it a 100 times and he doesnt find anything wrong....

At this moment,Deviante and Wuepe are talking in another channel. In a couple of hours we will know their thoughts and if we can hope for a psp port to be released.

I just say it again: WE ARE VERY VERY CLOSE!
