Where it all began ... We sell special cartridges to be able to play lots and lots of DS games in one. Soon we are going to sell 3DS cards that will play actual 3DS Games.
We do Wii mods to be able to play back-up games through DVD-Rs, Hard drives and even USB Flash Drives (Eco Version). Any model of Wii system will do for Hard drive and USB Flash Drive capability, but only the older systems are capable of reading DVD-Rs.
We install custom firmware to your PSP1000, PSP2000, PSP3000 to be able to run homebrew and back-up games from memory sticks.
I have a partner who mods X-Box 360 -N- PS3. If interested I can refer you to him.
