You cannot have more than one saved game per Pokemon Ruby game cartridge. There can only be one saved game per cartridge.
Anywhere on Iron Island, just insert a ruby cartridge.
you have to trade all of the hoenn-exclusive Pokemon from a Pokemon ruby/sapphire/emerald cartridge
I don't think you can because 'Pokemon silver' game cartridge is bigger than 'Pokemon ruby' and so you couldn't do it.* *because the cable to trade, is a long thingy, whereas a ruby game cable is a semi- circle thingy.
You're not even making sense. You can choose to start as a boy or a girl (Unless you're playing Red/Blue/Green/Silver/Gold). No Ruby changes that. Or were you talking about the game cartridge becoming a Ralts?
If the screen is just white when you put in the game, there may be something wrong with the GBA or cartridge.
Pokemon ruby's version IS Pokemon ruby.
It's a different color, normally a shade of purple.
Pokemon Ruby has Pokemon that Pokemon Sapphire does not and Pokemon Sapphire has Pokemon that Pokemon Ruby does not.

The cartridge is non-standard dark black, because of the built-in IR port, though the sticker is white.
One possible problem could be wear and tear on the internals of the game cartridge. This is more likely if the game was bought used or if the game used to save properly but now does not. If the game never saved properly and was not bought from a reputable seller, it is possible that it is a fake copy of the game. A few telltale signs are the cartridge itself not being red and slightly transparent or the label being crooked or not shiny. Despite common beliefs, this is not an issue with the battery. With Pokemon Ruby, the internal battery of the cartridge only controls the internal clock. While clock-based events, such as berries growing, will not function if the battery is not working, saving is completely unaffected.
