Fair statement :) however if someone was emulating say Dos or Mac OS. a keyboard would make it a fully fledged computer.

Sony might not use the IRDA port, but it's used by a TON of homebrew folks. We have programs that use it as a remote control, programs that access your cellular phone, programs that transfer data between PSPs, and many programs now support IR keyboards. Everything from Quake to IRC apps are using a...

Removing the IRDA port from the slim was the worst thing Sony has done.


you mean removing a port that no official software supports and in turn adding another (tv out) that all software can use out of the box was the worst thing they could do?

i don't think so :)

you should try both kernel- and usermode adress, eg when EPC=0xxxxxxx then try 0xxxxxxx and 8xxxxxxx aswell

compile with -g, then use psp-addr2line with the EPC adress to find out where it actually crashes.

also for random crashes that have no obvious reason the usual suggestion is to look for alignment problems.

thats pretty trivial, something like that:

for(i=0;i<size;i++)
{
putpixel(i,halfsize+(audiobuffer/somefactor));
}

do that after every swap of the audio buffer and you'll get something like the scope visualisation in xmms/winamp

Or the best option is to upgrade your 1.5 to Dark Alex's 3.03 OE-A (then upgrade to OE-B). This provides all the abilities of 1.5 with the added bonus of running the 3.03 firmware so almost all current games will run fine.
i'd rather not use anything that touches the flash... devhook is fine =)

i can't see how kxploit would be illegal, even if the dmca would even apply here (which i doubt) then the interoperability exception would still be there, and allow you what you are doing. i won't be worried at all.
