Capture Trainer Pokemon

For this glitch to work, you need to have not caught the Latios (Sapphire) or Latias (Ruby) roaming in Hoenn. (Note that this glitch means that, on this file, you cannot capture that Pokemon without trading.) Enter a trainer battle of some sort; this Trainer must have the Pokemon you wish to catch, exactly as that Pokemon is. You can, for example, enter Battle Tower battles to obtain a quick Level 100 Pokemon. (Note that non-Battle Tower Pokemon may turn into Bad Eggs!) Lose to the trainer and then proceed to beat Latios or Latias without having any battles - wild or Trainer - in-between. You MUST make the Latios or Latias faint in that one encounter, without catching them or them escaping. Repels are useful to circumvent wild battles, and Mean Look and Shadow Tag to prevent Latios/Latias from leaving.

After beating Latios/Latias, Pokemon #2-#6 of the previous Trainer's party will be used right after that, as if the Latios/Latias were their first Pokemon. These Pokemon will fight, however, as wild, roaming Pokemon do and thus are capable of escaping like Latios/Latias are. Still, you are nonetheless able to capture them as your own. The battle ends with the first Pokemon you catch, so if you want to catch a different Pokemon in the opponent's party, you'll have to defeat the others until you reach it; this can make for some easy EXP. as well.

Yellow Scarf Glitch (Japanese Version)

In the Japanese versions of Ruby and Sapphire, if you visit the man in Pokemon Fan Club in Slateport City that is sitting on the couch, he will give you a colored Scarf to Pokemon with maxed Contest stats: Red for Cool, Green for Smart, Yellow for Tough, and so on. Strangely, if you have a Pokemon with max Smart stat in the Japanese versions and speak with the man, you will get a Green Scarf, and if you do it again you'll also get a Yellow Scarf - regardless of the Pokemon's Tough stat!

Stevenless Dive

In order to progress the story, you normally have to go to Steven's house, and there will be a scripted scene in which he gives you the Dive HM. After you beat the Elite 4 and go back to his house, there will be a note and a Beldum waiting on the desk. However, you can skip/alter this sequence and trigger a failsafe put in by the devs. Do a trade so you obtain a Pokemon that already knows Dive, and skip Steven's house entirely. When you go inside the house after beating the Elite 4, you'll find that the note has an extra line, and both Beldum and the Dive HM are on the desk.

Pomeg Berry Glitch

For this glitch to work properly, you must have a Pomeg Berry and a Pokemon who has not had their HP lowered as much as possible already through Pomeg Berries. (If the latter is the case, the use of HP Ups on the Pokemon will suffice.) Get the Pokemon to a severely low level of HP (1 or 2 HP). Once you do so, in the field, use the Pomeg Berry on the Pokemon. This will in turn cause the data in their HP to cycle back to the top of the counter, giving the affected Pokemon 65,535 HP - over 90 times the otherwise possible maximum in the game.

Contributed by: Anonymous 

Level Up Unhatched Pokemon

To do this glitch, you must first execute the Pomeg Berry Glitch, which is done by using a Pomeg Berry on a Pokemon with 1 or 2 HP so that its HP loops to 65,535 (displayed as ?35 in-game). Do so, however, with only one Pokemon and an Egg in the party, with the Egg in the top-leftmost slot of the party in the Pokemon menu. After executing the glitch, you will now be able to enter battles and use the Pokemon Egg as if it were a normal Pokemon. It will function as a normal Pokemon - you can view the stats it will have upon hatching, it can level-up by beating Pokemon, it can learn new moves, it can even evolve. This means that you can alter the Pokemon inside the Egg in otherwise-illegitimate ways. For example. Pikachu cannot normally know Thunder when hatching from an Egg at Level 5; through this glitch, Pikachu can. Similarly, you can hatch Eggs with fully-evolved Pokemon such as Typhlosion, Meganium, and so on, inside.

Instead of saving, just power on/off the console or reset it (depending on what you're playing on). When you reload your file, you'll notice you have the Pokemon in your party, but those that were in your PC earlier are still there too! You've now cloned those Pokemon!

Avoiding excessive Rock Tomb use during Roxanne's fight

The Gen 3 AI considers Rock Tomb a Speed control move, and will therefore immediately stop using it as soon as your Pokémon becomes slower in favor of another, non-STAB and less useful attack in its place.

Keeping this in mind during the battle and possibly manipulating your EV Speed training can help you deal with Roxanne's Pokémon more easily, as they won't spam their STAB move as freely even when supereffective.

Her Pokémon's Speed Stats are as such:
1st Geodude: 11
2nd Geodude: 9
