Saw this on tumblr a couple days ago; a bit more complete rules:
-If a Pokemon in your party faints, you must release it.
-Every time you reach a new route, cave, etc., you must catch the very first Pokemon you see, regardless of your current number of party members. The Pokemon may sit within the box for an indeterminate amount of time as a backup.
-If you fail to catch the first Pokemon you see, either via it fleeing, knocking it out, or having no Pokeballs, you may not catch another. Tough shit.
-This means you can not catch a pokemon in a route you were in before you could catch pokemon. So no route 1, you were there before you had pokeballs.
-I can only ingame trade, not gift pokemon
-You must nickname your pokemon so there is some sort of attachment. Each pokemon is a best friend to you, to see them die is heartbreaking.
-BLACKOUT=Gameover, why? Because you shamed yourself thats why!!
-I can only buy normal pokeballs, the other ones (Great Ball, Ultra Ball etc.) are only to be picked up
-You are, under no circumstance, allowed to get a second pokemon from any given area.
-You are, under no circumstance, allowed to use items outside of battle. If you were poisoned on your last turn of the battle, you better hope to god there is a pokemon center nearby.
-You may not switch out before the enemy trainer sends in a new Pokemon.
-You are not allowed to use legendaries in battle.
I'll be doing it once I get SS at easter. I currently am playing through HG and am almost done. MS paint? Yes. If you remember my fantastic lynch votes during Super Mafia, you should be looking forward to my tale...
