Good to see you back at it! It's been some time.
That list of natives is basically all I use, although some are better explained in the natives.h that comes with scocl, so I'd advise looking through that.
The fastest ways to test scripts that I can think of are:
Testing on PC
Testing with an xKey on an Xbox (If you have either, both preferably lol)
Data transfer? (Still not too hot on the PS3 side of things after all this time )
Or if you know someone with an xKey/JTAG xbox you could compile your script and ask them to test it. (I would but I don't have an xKey).
OR if you compile your script then upload to mediafire.com and PM me the link, I may be able to get someone to test it.
(That's not a promise but I can try my best, although I can't ask every time you need something tested, after all it's all as a favor not a IOU).
Hope this helps somewhat.
