Are patches PS model / Modchip type dependent???

[tif]

I have a model 7002 Playstation (UK PAL), and I'm trying to back up TOCA WTC and FFVIII, which I know both have copy protection.

I've downloaded patches for both, and tried two different patches for TOCA and one for FF, but after creating my .bin, applying the patch (which seemed to graft on fine each time) and burning the new image from CDRwin, I'm still getting coasters!!!!

The CD's load OK to the patched section, and I get the PAL/NTSC selection in the case of the multi-cracks (and this part works fine) but then the games are still hanging on the protection checks.... any ideas what's going wrong here? does it have anything to do with my model of playstation??

I don't think there's anything I forgot in CDRwin.... I'm writing RAW mode2 2352, jitter off, error ignore, subcode auto.

The cracks should be OK too... they're coming from Paradox and BAD, so I don't think the problem is non-working cracks either.....
