I just bought a Nintendo DS(Original), and had a question or two: 1. Is it okay to leave it on the charger while playing it? Since i'll be mostly playing it at home, is that okay? Will it mess with the battery in any way? 2. I've heard that if you replace the battery on a DS, it removes the firmware, and can stop it from getting onto WIFI and other such things. since the only reason i am getting an actual DS, instead of just using an emulator, is to be able to fully use WIFI, and multiplayer, is it possible to load the firmware back onto the DS? Is it possible to replace the battery, and not lose the Firmware? 3. I'm getting a Supercard DSTWO this week, and i was wondering what games you would suggest i load onto it. Any Homebrew i should download? and where would i get them?
