Hi,
in ps2client we can't load a file bigger than 65536 bytes so i made a patch :D

This is during execiop, right?

Strange.

Thanks for the patch, though. :)

hello ooPo,

No, it's when you load an elf (execee) which load IRX bigger than 64Kb

cheers

The reason I ask is that I was told the largest transfer to ever expect from ps2link would be 64k. I'm wondering if some part of ps2link may not be checking a buffer size somewhere and overflowing.

[ooPo]

Source in cvs has been updated. If a read or write is over 64k, it allocates a bigbuffer and uses that, otherwise it uses the same old buffer. This is to avoid a bunch of malloc/free calls when possible.

Thanks for pointing it out. :)
