Here is my Modded slim star wars edition psp and cr-3100 connected . This is my first mod on a psp. and it went fairly well so I decided to share some pics and info and lessons learned.
Here is the completed cr-3100 internal mod install.I have one single 16 gb SDHC class 6 in slot 1 for now. I have an 8 gb laying around but its a class 2 and way to slow. so I left it out.
Here is the cleared UMD drive area.
Here is my mock up for the cr-3100. I set it on the metal so when i opened the UMD door it would lift the 3100 up for access.
Here is the slot I cut for the adapter to slide through. The psp is broken down at this point. Make sure to cut your slot for the adapter not the ribbon cable as you need to slide the adapter through the hole and feed the cable through.
Now here comes the hardest part about this build. You need to assemble the motherboard and card slot and then put the adapter in all the way.
Then reassemble.
I cut off the tab on the cover for a tight fit, and i widened the slot above the card slot. so the cable didn't get crushed. Sorry no pics of that.
Then I got to work on the cr3100's mounting.
I put some heavy Hockey stick tape on the bottom of the cr-3100 to hold it down and hinge. I assembled the door and rested the 3100 on the metal brace. Now when I open my UMD door the cr-3100 pops up for access.
Thank you all for this site and any info posted that helped w my build. Im standing on the shoulders of Giants.
