Gamecube POT Value issue
Gamecube POT Value issue
Hi there.
I found this forum via emu_kidid blog
I have a Gamecube model dol-101 with Xeno Chip, I play games with Cursor 12cm DVDs. But the problem is when the game throw me a DRE, obviously i have to adjust the POT, but the multitester throw me values nothing to do with the real value of the POT.
Here is a picture taken recently:

As you can see, the resistance value is on 2000 ohms, and the POT value is 050. I've bougth the mulstitester in a electronic store very cheap.
Is there a solution????
PS: I'm going to buy another multitester, but i don't have money right now D:

Re: Gamecube POT Value issue
Your Gamecube POT is at 50ohms. What you need to understand is that when you set your multimeter to 2000Ohms, it's not going to change the POT value, but rather 2000Ohms means that for values up to 2000, show them as they are and anything higher, show it as the number divided by 1000 (so 3000 Ohms will be 3K).
If the Gamecube is having trouble reading the discs and the POT is actually at 50ohms, I might suggest that you buy some better media (Ritek G05 - white printable top), clean the laser lens, or buy a new(er) laser and use it to replace yours.
P.S. to actually change the POT value, you use a something like a phillips head screwdriver and physically turn POT on the PCB.

Re: Gamecube POT Value issue
Thanks for the fast answer. I know basic electronic, because i've changed the value of the POT before. I saw videos that says how to adjust correctly the POT with the multitester at 2000Ohms. I've trying, but always throw me an incorrect value.emu_kidid wrote:Your Gamecube POT is at 50ohms.

I have cleaned the lens before but was a time that my Gamecube died for playing backups and never tweaked the POT.
But well, I'll keep trying.

Re: Gamecube POT Value issue
I heard that going below 100 ohms is very very bad for your laser, if it still works try scaling it up to 111 ohms (my perfect spot).
Re: Gamecube POT Value issue
I'd once asked the xeno author and he said even going to 0 ohms won't harm it. Have you ever heard of a laser "dying" from people putting the pot too low and reading GOOD media? It's the bad/cheap discs that will kill it not the low resistance.
Re: Gamecube POT Value issue
that means TDK mini dvd's can be added to good media
and try to find a guide to mod the pot (mod-chip.com has various guides along with each chip they have for sale), there you know on wich spot you need to connect the multimeter to to see the resistance. (sorry for my bad english I'm not completely awake yet :p)
@emu_kidid I heard the gamecube can read dvds burned on 52x if you put the pot ridiculesly(I think) low, but is that save? I heard it is save to burn it too low, but not to high.

Re: Gamecube POT Value issue
I did not even know that it is possible to burn DVD with 52x... CDs yes but DVD...?

I guess they're around somewhere, don't expect them to be cheap tough :pandzlay wrote:I did not even know that it is possible to burn DVD with 52x... CDs yes but DVD...?
Re: Gamecube POT Value issue
Just read at the german wikipedia that 24x is the maximum.

TDK CMDR14G-CAF WM1B-066 120
are crap nothing but DRE's try RE0 or Eternal Darkness you'll soon find out.
If your burning any mini DVD quicker than 4x expect problems, any these are set to burn at 2x only

Re: Gamecube POT Value issue
1. 52x DVD writers do not exist and there are no discs rated at that speed. 52x CD writers on the other hand, do.
2. Use a good DVD writer.
3. Burn discs at the rated speed.
I have had no issues with a good DVD writer burning good media at the speed it was rated for. I use full size Verbatim DVDs burned at 16x and my Gamecubes read them fine.

Re: Gamecube POT Value issue
Yeah, full sized discs are better supported in general.
