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?

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...)
