In any Pokemon game, you always want to catch a Pidgey first. Because by the time you get 'Fly' it'll be a Pidgeot.
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.
The only difference is that there are different Pokemon in each version like Ruby/Saphire or Pearl and Diamond
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.
Because its a hacked or modded version of ruby, yes they will work. Just be careful what you use at what time in the game or event.
