GREEN FIX..... no idea, I heard it had something to do with playing a NTSC dvd on a PAL tv? I dunno.

---> When you connect your ps2 to your Tv using a RGB/SCART cable and insert a DVD, the movie will look green, this simply removes it
No need to enable it though when using non SCART cables

DVD9 DL SUPPORT

--> Normally copying a DVD9 media like Gran Turismo 4 or Xenosaga I is doable although your ps2 might not recognize the disc or only play layer 0
The reason you can play Xenosaga with this option off is because the data being read was on the first layer, but as soon as you come accross a passage that needs data form the second layer your ps2 will show a black screen and then go to the Memory Card Menu


PSX MULTI DISK

--> Enables you to be able to play Ps1 games that require disc changing (some games have an option to save before changing the disc, some don't, like Metal Gear)
... or wait does that mean does discs that have several games all in one? (someone please correct me if I am wrong)

MC16 PATCH

--> Allows you to use unofficial Datel or other third-party-programmer non-standard Memory Cards (like 16,32 or even 64 MB)


ATAD AUTO PATCH

--> This is used for Harddisk Games involving HDLoader/HDAdvance (some games like Resident Evil cannot be copied to a harddisk without this option on)
This also allows you to play some games online using a modchip IIRC
(What it does, is patching on-the-fly a file called ATAD.IRX on your CD/DVD)


For the other questions I dont know as I have a PAL Ps2
