Comments

I don't think there are ways to raise the shiny chance in Ruby. Poke radar and Masuda method were both introduced in gen 4.

I have no experience hunting in Gen 3 but I know you can have a Pokemon with Illuminate (or Arena Trap) at the front of your party to help you get encounters quicker. There's also holding down the b button while on the acro bike to bunny hop which is helpful for getting encounters in place while not using up repel or Safari Zone steps.

Without using cheats or any RNG manipulation I'm unaware of, the shiny odds in Pokemon Ruby are capped at 1/1892, so you're pretty much stuck running around until you get something. If you're serious about shiny hunting in Ruby, then I'd recommend obtaining multiple consoles and cartridges so you can get more encounters in a shorter amount of time.

Again, I am no expert on shiny hunting in Gen 3, so take my words with a tablespoon of pepper.

Unless you want to trade eggs to another trainer, or get lucky with a dead battery early shiny frame, fish and summum covered 100% of it already

Answer 1

Ty said I should answer so sure.

In Pokemon Ruby, the shiny odds are 1/8192, and as mentioned by sumwun in the comments, there are no methods like the Poke Radar or the Masuda method to increase the odds. Unless you're open to using cheats or RNG manipulation, your only option is to challenge the odds, running around until something finally shines.

When it comes to the actual hunting, if your leading Pokemon has the ability Illuminate or Arena Trap, it will increase the likelihood of you encountering a wild Pokemon. Doing a bunny hop with the Acro Bike by holding the B button or using the move Sweet Scent outside of battle can help you get wild encounters without taking steps which is useful for the Safari Zone or if you're doing a Repel trick (not an expert on this but a repel trick is basically leading with a certain leveled Pokemon and using a repel to phase out some of the encounters so it's more likely you'll encounter your target).

Another general tip is to acquire more consoles and games. More games won't increase the odds, but they will increase the amount of encounters you get at once so hopefully, you get your target sooner than if you had one console. If you're serious about shiny hunting in general, I would definitely recommend this, given you have the funds.
also I know questions about emulators technically aren't allowed but if you have speed up that will help you get encounters quicker.

Side note, Flame Body only speeds up the hatching process in Emerald onward so I would definitely stay away from egg hunting unless you're just really determined to do so. If so, use the Mach Bike and pray for good luck.

TLDR: There are no methods to increase the shiny odds in Pokemon Ruby, but you can utilize abilities/items/resources to speed up the hunting process.
