I just want to double-check as I believe James did a good job of
explaining the distinction between what's okay and whats not: Bypassing
the libraries with your own functions is okay -- But directly accessing
hardware functions/features (other than the cpu :^) is not.

If my understanding is wrong, please let me know!

So it should be fine to shove your own primitives into the OT, but
accessing the light gun (as someone was discussing in another ng post)
or using the dual-shock (didn't someone get that to work?) would make
you non-eligible for a CD.

There's no such thing in the real libs because no real developer would
use it! Why would you incur the overhead of formatting your data for a
routine plus the function overhead for something as simple as sorting a
single polygon? (Especially since you'd most likely be doing it several
hundred times per frame? The PSX is only a 33Mhz cpu remember...)
