Two days ago i got 5 pcs sample of modbo 520 and 5 pcs of modbo 745.
the modbo 745/760 are for v1-v16 and the modbo 520/530 are for v1-v13.
I've installed this chips on V3 PAL, v4 NTSC, v5 PAL, v13 PAL, v14 PAL and here are my results:
on the V3 PAL, no sccess with both the 520 and the 745, i've been told that it's works on V3 NTSC but didn't had console to test it on!!
installed 520 on V4 PAL, working VERY GOOD!
installed 745 on v5 PAL, working VERY GOOD!
installed 520 on v13 PAL, working VERY GOOD!
installed 745 on v14 PAL, working VERY GOOD!!
tested all media types PS2 CDR, PS2 RIPS, PS2 DVD-/+R (didn't had DL to test but it's sould work fine!)
also tested ps1 games on all of those versions, and worked just fine without any problems.
and now for the treat
configuration settings 100% works!!!!!!
you can change the chip settings , save it, shutdown console and works fine WITH THE NEW SETTINGS after booting!!!
I played with the color settings (from ntsc to pal and back) also played with the Y fix, and it worked perfectly
the 760 and 530 version are just a low count wires version of 745 and 530. thay have a spacial shape that you can fit directly on the bios pads to solder without wires.
