OK guys, seriously...
First, USE THE SEARCH FUNCTION! I have answered this question twice today (this will be the third time today and I think 5 times in the last 2 weeks)
Second, This is NOT the proper section to post this in. this belongs in the regular PSP Slim section not in the tutorials section. the tutorials is a reference section for tutorials only.
Third, If you had gone to the regular PSP Slim section you would have seen the very first topic after the stickies is entitled "
PSP Camera mod!"... (that bold topic title is a link to that same topic, btw...)
Fourth, as I answered that one and posted a link, I will answer this one the same and post the same link...
We do have a tutorial for this mod, it even includes links to disassembly tutorials...
One word of warning: You can not use any camera other than an official PSP accessory camera (Chotto Shot or GoCam, or whatever it is called in other countries) for this mod. not just any camera will work, and changing out the optics from another camera will not work either.
Here is the link:
