Description
Pokemon Tourmaline is a Completed GBA ROM Hack of and loose sequel to Pokemon Emerald. This game is intended to take place in an alternate timeline where the setting and events have diverged a bit from the official games. Most notably, some mechanics from later gens are absent while others have been reworked, and a number of new mechanics have been introduced.
Story
It’s been several years since the battle of Groudon and Kyogre wrought havoc on the Hoenn region. Humanity’s understanding of Pokemon has deepened as more discoveries are made about the origins of Pokemon. A recent surge of discoveries in the nearby Issho region has drawn researchers from all over the world, including May, now an assistant Pokemon professor. After receiving a Pokemon from her, the player sets out to investigate the reports coming from all over the Issho region of new species of Pokemon, new types of Pokemon, and even more strange phenomena. Meanwhile, a new threat is on the rise in Issho, a mysterious crime syndicate who use exceptionally powerful Pokemon.

Change Log
v1.1.1
IMPORTANT NOTE: This is the last update that will be compatible with old saves. As of this version, the player can go to the Battle Frontier, complete the Issho Pokédex, and catch a few new things after becoming champion.
There are still a few bugs that I know of (bag space, Pokédex entries, etc.). I’ve been purposely holding off on fixing these to keep old save files compatible. These will eventually get fixed (and probably some other things that I’ve missed), but just be aware that you’ll have to start a new game by then.
As for future updates, well, I already said I wanted to do the full postgame some day, and I’m still optimistic that I can do it within the next few years or so. But I’m also taking a long break from game devving, so this is likely the last update you’ll see for a while. I’ll still be lurking here and on pokecommunity, so feel free to DM me with questions/comments in the meantime.
Thanks everyone for the support. If you enjoyed the game and want to continue the story in Hoenn and Ultra Space (and catch Pokémon from gens 9 and 10), I hope you’ll check out Pokémon Tourmaline v2.0 in the future!
FULL CHANGES
- May now recognizes a complete Issho Pokédex
- Reworked Battle Frontier tilesets to be compatible with the day/night system
- Changed Southern Island Lati@s encounter level to 40
- Southern Island Lati@s encounter now corresponds to the opposite player gender
- Fixed issues with the Inverse Challenge sidequest
- Added “with no collisions” to the Hot Wheels quest description
- Fixed some other typos
- Fixed various tile/collision errors
Known Issues v1.1.1
- EMULATOR SPEEDUP: This has a tendency to glitch the game in unpredictable ways. Use it sparingly and save often if you do.
- BAD EGGS IN PC: This happened to me once (invisible sprite in Box 3) and I’m not sure what caused it. Trying to access its summary screen crashes the game, so avoid that if it happens to you. Everything else in the PC box should still work normally.
- MISSINGNO GLITCH: This sometimes appears when using Cut or Headbutt. It should be harmless as long as you flee immediately. Do not attempt to catch it or interact with it in any other way.
- POKEDEX GLITCH #1: The Pokedex pages for new regional forms don’t show the correct sprites. The player may see the base form or a question mark instead.
- POKEDEX GLITCH #2: Some new Pokemon show the wrong Pokedex page when they’re first caught. Checking the Pokedex after catching them will show the correct page.
- STATUS BAR GLITCH: Enemy status bars sometimes show the wrong color for status conditions. For example, the BRN symbol may be black instead of the correct red color. This is a minor graphics glitch that I haven’t found a fix for yet. It doesn’t affect anything else and it often fixes itself, so just ignore it.
- WINDOWS AT NIGHT: Sometimes these will be strange colors instead of the correct yellow shade. Entering and exiting a building fixes this for now.
