There is no RPG Maker 2 or 3 for the PS2. The RPG Maker series has primarily been PC software, with only select console ports:
Japanese PS2 entries (RPG Maker 2 & 3) exist but were never localized. Western fans often discover them via emulation or import lists and assume English versions exist.
You'd need homebrew development (PS2SDK, devkit) or mod existing games—far more complex than using RPG Maker on PC. For most creators, PC + RPG Maker MZ + console export is the practical path.
