    About the Hack

    Pokémon Triver is my first major attempt at creating the kind of Pokémon game I always wanted growing up.

    Built using Emerald Expansion and set in a fully custom region — Triver — this hack gives players the freedom to play their way. The focus is on exploring an ancient world, uncovering secrets, and discovering Pokémon to fill your Pokédex.

    This demo includes content up to the 4th gym, showcasing a significant chunk of the region, including the first two of Triver's three major islands.

    Could you add more items and Customize walkthrough the game??

    1. infinity rare candy

    2. Pokemon's Nature custom

    3. Pokemon's Ability custom

    4. Max money

    The other rest of the game was fine 👍💯
     
    Back again with some reports and feedback.
    After I lost my first official battle to the rival that stops before going into a gym, some of the animations have seem to have broke e.i. moves like mud shot showed the proper animation before I lost now it just throws the Pokémon sprite at the opposing mon and some other moves do to but it only happens after your first white out. If you never lose you will never see the problem.
    Also QOL change the last option you chose in battle is the first option that appears in the next battle. So if you chose to run in a wild encounter, in the next encounter run will still be selected, which in turn might cause you to miss out on some rare encounters. Hoping you could fix that so Fight is the preselected option so someone doesn't click Run by accident thinking the new encounter menu is already selected to fight by default.
    This one is personal but a dexnav before the final update of this game would be nice. You have done an excellent job with route mons and you've give the player a wide choice to choose from, but from my time playing there's been times we're I think I seen all the mons a route gas to offer, just to backtrack and run into a mon I haven't seen and like I said in my previous statement most times the option you chose in a previous encounter will be the first option the arrow has selected in the next encounter so I have ran from many mons(like the axew in crystal cove). You don't even have to add the cool dexnav everyone loves it could be the basic one that just tells what mons are available or even just trainer signs on a route from the same purpose. Just time saving so don't downs 20-hour in one route because I thought I missed the rare encounter or have ran from it cus of the battle menu is sit up
     
    Hello, Kinda awkward but i have a question tho. after playing hours now to find a solution i am not sure if i missed something or am just stuck to a bug. after researching the crystals with the guy in the cave i cant go on. the boat guy is away so i cant cross over to crytsal cove where he wants to go. i dont have surf to cross it on my own and i cant go in south since i cant find an exit of flower glade. did i miss something? talked to like all npcs i found maybe i still missed something.

    Hey so the second part of crystal cove isn't worked on yet so not much
    If you cleared the town of the thugs the boat will move into the harbour. Although if it's more than that seems like I may have a fix to do. I recently overhauled the boat code when I introduced the third island so the latest version due end of month with gym 5 might fix

    You can head through dark cave and go to the desert on towards gym 4 and the mega tower. If you download the latest version it might have a fix for the boats though letting you do some other quests

    I have trouble buying from that guy in Pokémon Center, every time I interact with him, the game stops working and it freezes.

    That happened to me, too! I tried buying from him once and it soft-locked my game!

    I snapped a screenshot of him.

    I gave the game a try to possibly help out with feedback. I'm having fun so far! Here are some of my notes:


    I really liked how easy it is to just start your adventure. You get through the intro, you're given your starter, 5 Poke Balls, and then let loose on the world. Plain and simple. Really enforces that vibe that you're free to explore on your own. Level grinding felt pretty easy, especially with the optional Exp Share. Also, there was a fucking Meditite in the grass, near my house. Two words: THANK YOU! I love Fighting-types! Getting one early made me happy! ^w^

    As for some minor gripes, issues and bugs:
    • When my Partner Pikachu gets hit with an attack, he shifts way to the right as a dark silhouette.
    • When resting in the bed, it doesn't blackout and play the healing jingle. It's not a big problem, intentional or not, but I kinda missed it. At least it made healing quicker
    • Both a Fisherman said the same line as a Bug Catcher about "People worshipping bugs as strong as the sun." I thought that was strange.
    • (Major) There was this white-and-red NPC in Clay Haven that acted like a shopkeeper. When I tried buying something from him, it softlocked my game.

    I also brought some screenshots for evidence. I'll keep playing some more. I'm invested so far!
