basicly yes but haxchi also allows u to directly cooldboot into a custom firmware.
Now you need to go the browser boot homebrew booot a cfw play a game or boot homebrew again to install a game
haxchi would make that easier just boot haxchi or better cooldboot directly into a fw and install and play games
Heh, so went to get a VC DS game, but all nintendo sites have been blocked... gonna be a long day
