Pocket Gem Red is an unlicensed RPG by Nanjing Technology, one of the most prolific developers for the NES/Famicom in the 2000s. Featuring a vibrant 16Mb capacity, the game offers a massive world where players collect 'gems' containing powerful creatures. Utilize an elemental rock-paper-scissors combat system to defeat other trainers and conquer gyms. With its detailed pixel art and custom soundtrack, it is a high-quality example of the 'Nanjing-style' RPG that dominated the later years of the NES lifecycle.
