Yes, I'm double posting on purpose - Sorry but damn I posted this on 05-13-2008, 07:16 PM and not a single response after 58 Views. I was originally going to make a new thread however - I decided to just respond to myself.

Here's the deal. Read above and you'll see what I wanted, read below and you'll see what I've gotten.

Steps
1. - Install timemachine on all memsticks. Doesn't matter if you use the fat or slim to do it.
2. - Move all of your 1.50 homebrew from your GAME150 folder to your GAME folder on the memstick.
3. - Pick a game or application to use as a border line between 3.xx and 1.50 homebrew then rearrange your xmb application list accordingly. I use irShell and it comes in two flavors, 3.xx and 1.50. So in my XMB game list, that is where I draw the line. Everything from irshell 3.xx and up is for 3.xx firmware, everything from irshell 1.50 and down is 1.50 firmware stuff. There are a lot of utilities you can use to rearrange your aps. Use google.
4. Pandorize both batteries. I use the service tool to softmod both.

Result - I seamlessly share memsticks between my slim and fat PSP models. I retain my infrared on my fat for keyboard usage when I want to go on-line for chatting or email. I use my slim for everything else. For both PSPs I simply reboot holding the "O" to get to 1.50 and use those aps.

That's it. Problem solved. Works like a charm.

Sorry for the double post - it just seemed to make sense to do it for the given situation.
