you go to your room and see the time. Is that simple!
if you mean can you get Pokemon from pearl and diamond and trade them to ruby so you can get diamond and pearl Pokemon on ruby. then no you can not. but you can migrate ruby Pokemon. you put the Pokemon in ruby that you want to put on diamond or pearl in the PC. save it turn off. then go to diamond and migrate them. must be in ds at the same time. pal park.
Probably but it would take a lot of time
go in your house at littleroot town
last time i checked, it was between 15 and 30 bucks, try ebay.
In any Pokemon game, you always want to catch a Pidgey first. Because by the time you get 'Fly' it'll be a Pidgeot.
The only difference is that there are different Pokemon in each version like Ruby/Saphire or Pearl and Diamond
In your room there is a clock check the clock and you should know what time it is in Ruby.It even works in Emerald and Saphire.
because they only atavate at a certon time.
Time is not kept in leafgreen meaning there is no day or night.
Knock out all his pokemon. If you are that far in the game you should really know how to defeat a trainer.
The best way to raise your Pokemon in Pokemon Sapphire is to have all 8 Hoenn badges and trade them for Pokemon Ruby version. Doing is will make the Pokemon Ruby Pokemon evolve faster. It works like this because traded Pokemon will gain a boosted amount of experience so they will grow much faster. Example you trade a Rayquaza (Pokemon Sapphire) for a Rayquaza (Pokemon Ruby) at LV 70 once Rayquaza you received from Pokemon Ruby will gain boosted EXP points every time. And the same goes to the Rayquaza that was transfered into Pokemon Ruby. Traded Pokemon grow much faster in trades than normal.
In Pokemon Ruby, the time changes do not affect which Pokemon can be caught. The time changes affect day-to-day things, which is basically challenging someone else in their secret base.
