Pokémon Sigma Ruby is a ROM hack of Pokémon Omega Ruby. Just as Omega and Alpha, Sigma Ruby is named after Greek Alphabet.

The most important change in Pokémon Sigma Ruby is that not just the Inverse Battle trainer battles you with the types inversed, no, all battles are now following the inverse type effectiveness.

A complete list of changes such as those made to Pokémon, moves and evolutions can be found in the .pdf file included in the download.

Features

• The entire type effectiveness spectrum follows that of Inverse Battles (updated type effectiveness can be found at Serebii or Bulbapedia).
• The game has a new icon and banner.
• The game has a new title screen.
• Many Pokémon have had their base stats slightly updated to make them more viable.
• Difficult or impossible evolutions (i.e. trade evolutions) have been taken out.
• Some Pokémon have had their typing updated.
• There have been updates on move stats.
• Various Slateport City Market stores have had their items swapped.
• To improve the viability of the above various purchase prices have been swapped.
• Various signs have had their content changed. Try to find them all.
• Various gift Pokémon have been changed.
• Various static Pokémon have been changed.

Installation

This game cannot be installed alongside an already existing omega ruby as the romhack won't have a custom TitleID. Please remove any existing Omega Ruby first. You can first back up the save with JKSM if you want to. Since this hack makes no changes to the save file structure you can inject or extract the save file perfectly normal.

If you're already playing a copy of Omega Ruby you will have to remove all updates from that (CTR-U-ECRA/P/E/J is the ProductID for DevMenu/BigBlueMenu) or the romhack will not work. ​Incorperating the 1.4 update in the romhack is not only very tedious, but also dangerous ​because Nintendo can, and will ban your Battle Spot and GTS if not online entirely access/if they detect you are online with a hacked game (this was announced a while back and there are various reports of it, as opposed to popular belief that does not include pkhex'ed/powersaved mons).

The download has a xdelta patch along with the program, readme instructions on how to apply it and a bat (batch) file for Windows users to do so for them. Taken from the README:

• Place a clean Omega Ruby .cia rom in the same folder as the downloaded files.
• Rename the rom to omegaruby.cia.
• Run the patcher.bat.

Note that the text has been edited for the English version only.

Changelog

Version 2.0

• Completely rebuild the romhack from scratch because lost most of the original files. I used my own changes documentation and what I could remember to rebuild it.

Version 1.3

• Updated various parts of the story text to reflect changes made in the game elsewhere such as type effectiveness references.
• Various Grass type Pokémon had water immunity abilities which is a bother as Water is super effective on Grass. These have been changed.

  • Lileep and Cradily no longer get Storm Drain. It is replaced with Stench.
  • Cacnea and Cacturne had Water Absorb removed, their set of 3 abilities is now Sand Veil, Rough Skin or Sand Stream (Hidden).​

  • A backpacker in Lilycove City.
  • A PokeManiac in the Lilycove PokeCenter.

  • Various brown signs across the region.​
