Answering your previous post point wise
1] Actually there are three ways of doing a hard mod 1. Cutting the Pin, 2. Scratching the copper trace, 3. One wire method ........ You know the first two ..... In this link you can get info on the third one
http://www.pspmod.com/forums/hardwar...-hard-mod.html (How-To: Switchable Pandora PSP-Slim Battery (Hard-Mod)) ......... All three works.. Which process you want to do is upto you ..... The third process has the better chance of reverting the battery back to normal
2] No it will not loose any functionality ......... You can always format the magic memory stick to make it normal
3] Updating to 3.90M33, PSP will not loose any original functionality ...... It will only add to it's functionality ......... Yes you can update to official firmware even if you have a custom firmware
4] Size of the game can be from few hundred MB to 1.8 GB (Which is the maximum a UMD can hold)
