MOD Help - I've tried Neo2.2,2.0,neoKey,750X... V4, What am I doing!?

[ihaveanosebleed]

I've programed and installed many PSX mod chips no problem, I can't get
anything working on the PS2 V4! I tried a NEO 2.2 in 5 wire mode - nothing
I tried changing point 2 (the other side of the microcap) - Nothing, I
wired the 2.2 chip as 9 wires - PS2 would not eject! I removed chip and
tried building a NEO KEY with V2.0 and 750X code - Nothing, yes the link
wire is on board. Tried both USB ports, tried both green and white UBS
wires, tried reversing the 50V 1mf cap, NOTHING WORKS!!! I do not have a
63V cap to try, I read 12-100V will work. Yes the PS2 still loads
originals. I also tried the macrovision chip and that gives lines on
my VCR screen!

I do not want to take this PS2 apart again! for the LoVe oF GoD,
somebody help me !!!!!!!!!!

Well I've had some success this afternoon. I used the 750X Hex in my NEO Key,
changed the Cap to a different 50V 1mf, switched the wire to the left side
of the microcap (closest to center) and I was able to get 1 single PSX CD
to load, Worms Armageddon loads about 3/4 times, nothing else for PSX!?
worms was on a Verbatim, all my others are different. Also Worms CD was
closed, most of my other PSX CD's are open for new sessions and I fill up
the CD's with backup data as the PS1 only reads the first session on a CD.
I don't know if the PS2 drive is multisession or not, this could be a problem
for me.

I also managed to get Crash, Wrath of Cortex to boot, that was backed up on
a Sony brand CDR. No, I don't own a Gameshark 2 either, It turns out that
the InterAct Memory Card Manager CD can be used as a boot disk!! YA Hoo!!
It took me about 3 tries to get it to work and I never tried it again after
that so i dont really know what the success rate's going to be on that.
I don't know if this is normal or not but both the original and Backup
of Crash WOC are very noisy and take a long time to load the levels. I
don't have any other game on blue CD yet to compare. I have 2 DVD originals
that are a lot more quiet, and the games seem to load faster than Crash.

Should I try and get a 63V Cap? That seems to be the recommended type!?
Anything else I can try on my homemade NEO KEY to get better results?
