The Dragon Ball gaming community erupted with joy when Dragon Ball Z: Budokai Tenkaichi 4 (often referred to as Budokai Tenkaichi 4 or BT4 ) was released as a massive mod for the PlayStation 2 classic, Budokai Tenkaichi 3 . Developed by the passionate team at Team BT4, this isn't a standard ROM; it is a complete overhaul featuring over 500 characters, new transformations (Ultra Instinct, Super Saiyan God), and stunning new stages.

Note: This guide assumes you own a legitimate copy of Dragon Ball Z: Budokai Tenkaichi 3 for PlayStation 2 and have legally patched it to create the Budokai Tenkaichi 4 mod. The save file does not include the game ISO.

The standard BT3 cheat codes do not always work perfectly with BT4 . Many players find that using an Action Replay code to unlock everything causes glitches—specifically, the new characters (DBS Broly, Jiren, etc.) remain locked or the game freezes on character select.

However, unlocking all these characters—from Goku (Ultra Instinct) to Vegeta (SSGSS) and even obscure manga characters—takes dozens of hours. Nobody wants to grind through the Dragon Sim mode for the 100th time just to play as Bergamo.

That is where a file becomes your Senzu Bean. This guide will explain exactly how to find, install, and troubleshoot a 100% complete save file for BT4 on the PCSX2 emulator. Part 1: Why You Need a 100% Save File for BT4 Unlike official games, Budokai Tenkaichi 4 is a mod. It runs on the ISO of BT3 . Therefore, the save data structure is similar, but the unlock criteria are much stricter.
