You can find official Pokemon mini games on the official Pokemon website, but there are fan-made MMORPGs like UnovaRPG, Pokemon Legends, Pokemon Vortex, Pokemon Lake, and many others.
There will be a translation in the instruction manual that comes with the game. If you don't have this manual, look up "How to decode braille" There probably won't be any results if you add the "in Pokemon Emerald part
No, you cannot. The only way to keep Pokemon when you restart is for you to trade it onto another game, then trade it back onto yours when you need it. If you are restarting and you follow my method, then you should trade on Pokemon that have been purposely caught for that, like easily replaceable Pokemon that are common. For example: Zigzagoon, Wingull, and many others.
In Pokemon Ruby there is the 3 regis, rayquaza, latios, groudon, deoxys, and jirachi. So there are 8 legendarys.
There are many Pokemon you catch that are similar in sapphire and emerald but there are many Pokemon emerald can only get and not sapphire.
385 Pokemon.
Pokemon Emerald has a bunch of Pokemon, that are available to be caught! It's too many to list here.
