I am not familiar with the bandwidth constraints, but how does 1080p = 200MB/s? If you take RGB (3 bytes per pixel) * 1920 * 1080 = 6MB/s = 48Mb/s. 48Mb/s is WAY smaller than 1.6Gb/s. If you must byte align on 4 bytes (RGBA) per pixel... 1920 * 1080 * 4 = 8MB/s (which I originally stated in the fir...

For step 4, you should instead add to CFLAGS -DSOL_TCP=IPPROTO_TCP since this is the equivalent under Mac OS X (and, I guess, other BSDs). I already found find all those by trial and error. Maybe something like: #ifndef SOL_TCP #define SOL_TCP IPPROTO_TCP #endif should be added in one of the header ...

You might back up the info in case someone complains afterwards... then restore just that person. Don't know if that's possible, but if it is, that would be a nice thing to do just to be safe.

Modern MIPS CPUs can (partially) stall the pipeline and wait for the result to be availiable. So no interlaced instruction is needed but the delay is still here.

End then you'll need to use kernel mode and say goodbye to 2.00+ psps. I don't really care myself, but a lot of people do and it's something to consider if you like you're emulator to be 'popular'.

add "USE_PSPSDK_LIBC = 1" to libpng's makefile or type "make USE_PSPSDK_LIBC=1 install" (after running "make clean" of course)
