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
v1.0.6
- All HM distribution events now account for when the player’s bag is full, fixing potential softlocks.
- Some of the longer dungeons now have NPCs who provide the player with shortcuts in exchange for a fee. These NPCs only appear on Normal difficulty.
- It’s now possible to lower, but not raise, the difficulty setting (talk to NPC on the PokeCenter 2nd floor).
- Restricted saving to PCs only on Insane difficulty (keep in mind this means you can’t save if you have no money left; you’ll have to earn more somehow or lower the difficulty).
- The difficulty setting now displays on the Hall of Fame screen.
- Fixed Violet/Vert not healing the player’s party in Cinerous Tower and Mindaro Gardens.
- Fixed Celebi event glitch that let you battle it infinitely many times.
- Fixed potential softlock in Route 68 boulder section.
- Fixed some misaligned holes in Broadcast Tower.
- Fixed tile error preventing the use of Surf on Route 88.
- Fixed some typos.
- Fixed various incorrect icon sprites.
Known Issues v1.0.6
- 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.
