So let's re-implement more features. How about some single player features? /save 3 saves the game in slot 3, /load 2 loads the game in slot 2, /aw gets you all weapons and /powerup powers them all up. Additionally, /shield 2 gets you the lighting shield and /shield 4 gives you the laser shield. /shieldtime 60 gives you one more minute before time runs out, not a re-implementation but cool anyway.

Oh, yeah, don't forget about /insertcoin that switches to splitscreen, takes one of your coins, inserts them into the new screen part and spawns a second player there. If you want one more player, just type /insertcoin again. You could use /insertcoin 3 to pass one of your lives to player 3 if player 3 has run out of lives. Using /list in local games and LAN games throws them onto the net, /unlistlan unlists an internet game and switches to LAN-only, having all players outside the LAN time out after a few seconds.
