your only options for a go are either:
1. if your fw is 6.20, you can use tn hen, which is an enhanced hen with ps1 game compatability, plugin compatability, and great homebrew compatability
2. if your fw is 6.35, you can use 6.35 pro, which is a light custom firmware that has ps1 game compatability, psp iso compatablity, plugin compatability, although i hear the homebrew compatabilty isn't as good as tn hen
3. if your fw is 6.37, there is no hen or anything but you can play a variety of signed homebrew that work with no hacks needed
the hens can be found here

http://wololo.net/talk/edit: oh i didn't know about the 6.10 exploit but that one is most likely outdated. tn hen and pro are better
and remember, no matter what anyone tells you, you cannot install a custom firmware on a psp go or you would most likely face a brick
I have been using HEN and its been working brilliantly .
Thank you so much.
