Help with modding white Sanyo board Saturn

Hi, I finally got around to modding my white saturn, but it won't load any backups, it plays Audio CDs just fine, and I have no Japanese games to try it with. I think I did everthing right, with the AB method, has anyone modded this kind of saturn before?

Here are some pictures I took:

Chip with AB


Power Cable


Maybe the problem is the power cable, the saturn in the tutorial has 5 pins on the power supply, but mine has 4, my american saturn has 4 too, so I soldered to the same pin.

Any suggestions?

did you check the voltage on your pin? how many pins does the ic on the cd-board have?

I'll check the voltage today, I did not connect the signal cable to the board, I made a bridge with solder from point A to point B on the chip, here's my Saturn, pre modding

After some googling, I found a guide in another site that said this:
Step 2: A+B method.

If you have a Japanese Saturn you cannot use this method, move onto step 3 for instructions. To do the A+B method you simply solder signal wire A to point B on the Modchip. Alternativly you can completely remove the signal wire and create a solder bridge between the two points. The solder bridge is probably a better way to go because it just eliminates possible future problems. Its important to note that on Sanyo Saturns the A+B method does not always work. I recommend trying this method first though, read step 3 for more information.

Step 3: Alternative to A+B method.

If you have done the A+B method, then you can skip over this step however it may not be possible to use the A+B method with all Sanyo Saturns. The following method is to my knowledge fairly untested on US and Euro consoles. It will not damage your system but there is not a guarantee it will work. You need to remove the CD drive from the console (simply disconnect any power inputs and slide it off the posts) and turn it upside down. Locate the Sanyo chip and trace pin 7 to a place that has easy access to solder Signal wire A to.

Again this method is not documented well, and I currently do not have any pictures to help you out. Its worth a try if the A+B method doesnt work.

Anyone try this before? I flipped the laser over, and found 3 chips that had Sanyo printed on them

try to get the data-sheets of the ics, so you can figure out which one has what to do.
