Many questions about: PAL/NTSC and Ripping

[cLeAnEr-23]

Guys... hehe.. i'm confused
Please can' someone answer this question ??

I have a PAL PS2 with a Neo 2.2. and AS2.2.
Now i have a few questions:

a.) I have a original "Ready-to-Rumle 2" game on CD (not DVD),
i try to copy that with a Plextor 2410TA and newest CloneCD
(with Subchannels Read on, blabla..)
Why i can't get the disc booting with my AS-2 like every other backup?

b.) i have 5 Japanese orginal CD-to-CD (also CloneCD) copies.
All in JAP (NTSC) format. Any way to fix this to load on my PS2 ?

c.) I have a few ripped and patched images, but ups..
i have downloaded some NTSC Ripped Games...
Any way to bring this alive on my PAL PS2 ?
The backups won't load on my AS2. The Screen "Freeze"
at the menu of AS2 and end... Why?

d.) If i make a DVD to DVD-R 1:1 direct copy... Is there any need
to patch the DVD-R Image or works this ok without any patches ?
