Hiya!
just received a GC with a working drive and installed a spare xenoGC I had... the chip goes to GREEN led and the XenoGC intro works.
The original GC pot was set at ~218ohms and it could not read backups (backups that were working fine some years back with a viperGC extreme GC I had).
I tried the 170~230ohms range without success.
I went up to 500ohms (read about that on a tutorial on 128bit.me) but then even originals would not boot.
So I started working under 170 and GC started booting games at the 130ohms area.
Is it a "safe" value? Should I start tweaking so I can go up 10-15ohms or should I just leave it since it works there? ATM I have left Zelda WW playing to see what happens past the 10mins mark, seems to be doing fine...
How do you feel about pot adjustment at 130ohms?
Re: How do you feel about pot adjustment at 130ohms?
Try metroid prime 2, or starfox for an hour. 130 ohms is fine, you can even run it at 0 ohms and the xeno will read dvd-rw

^ thanks for the suggestions, I left ZWW for ~30mins and turned it off... will let the suggested games run for an hour will I finish the megadrive installation on the 2nd mobo 
Re: How do you feel about pot adjustment at 130ohms?
test completed successfully, no DREs with Metroid Prime 2 playing for over 1 hr...
I did get trouble booting the GB startup disk (same media/burner) so I took it down to 127ish... hope it's OK for the years to come (not that it will see much use with the wkf installed also...)
