Thanks to your inspirational pictures, I too underwent some heavy moddings
Here is the result in the attachment.
The bigger buttons and new pad are definitely a vast improvement. Now the console finally respond more or less as it should. The skin is all right but I'm planning on making my own, I think this one take too much attention while playing, it's hard to focus on the game (By the way if anyone has some new skins of they own please post them here). I also added 2 more stereo buffer inside, which add some bass. Great result, although I didn't dare to make holes on the back of the console so the sound isn't as good as it should.
Anyway thanks for the insights
