Hello everyone!
My name is Jiro, and I have been a passionate Pokémon fan for as long as I can remember. Over the years, I've followed Pokémon fan games, ROMhacks, and MMORPG projects, all of which inspired me to begin creating a Pokémon world of my own. What started as a collaborative MMO project back in 2016 eventually evolved into a completely independent journey, leading to the creation of Pokemonia.

The Story Behind Pokemonia
In the early years of development, I focused on building MMO systems such as:

• Player Parties
• Automated Tournaments
• Showdown Battle System
• Guild & Community Systems
• Custom Multiplayer Features

While these systems worked well, I felt the project lacked the authentic Pokémon adventure I wanted to deliver. In 2023, I made the decision to rebuild Pokemonia around Pokémon DS ROMs, First using Pokemon Platinum to bring the beloved Sinnoh region into an online multiplayer experience. Pokemonia requires an official Pokémon Platinum ROM to play.

To make this vision a reality, your support, reviews, and feedback mean a great deal. Every player who joins, shares the project, or provides constructive feedback helps push development to the next level.
I hope to see you in-game soon! If you'd like to chat, ask questions, share ideas, or simply follow development progress, I'll be available on our Discord server and would love to hear from you.
