Here is what I know about Ruby as of now.
English game to come out on March 19.
YOu get three choices of startes in Mishiro Town(actually, just outside of town)
Mudkip, the water(later water/ground)
Torchic, the fire(later fire/fighting)
Treecho, the grass(stays grass throughout)
There are a total of 386 pokemon in R/S(202 of which are obtainable)
As of now (3/10/03)there is no way to trade from R/S to Red/Blue/Yellow/Gold/Silver/Crystal
Here are a few gameshark codes.
ruby/sapp gameshark codes: may spoil your game!
infinity ticket: 020259f4:0113
---(never yet tested)
latios/latias (route 120 only): 02038ffa:2300
---(i never use it since i already captured latias after beating the elite 4 and the champ)
gameshark codes: they really work!
Infinite money : 08A1A6997591DB20
Infinite masterball : 0945EE43F1B91645 and EE25BB6E 22C0C18F
---(use these two codes simultaneously)
Infinite rarecandy: 020259f400630044
---(please be aware that feeding rarecandy to your pokemons to level them up doesn't fully develop themselves to their full potentials)
Use this code instead to level up your pokemons:
enemy at level 100: dc8a10b0bdef9cb4
---(experience points will be based from a level 100 stats but your enemy is still at a level where it really is...so expect your starting pokemon to have evolved in its second form just when you first meet your rival...very easy!!!)
"Earning your success the hard way gives you feeling beyond comparison."
I hope this helps.
