Well, well, well guys..We meet again. As I promised, here is a guide on how to patch Prometheus-4 on ISO by using ISO Tool v1.93. I have tested all the steps on 3 different Custom Firmwares and they are : 5.03 Gen C, 5.50 Gen D3, 5.00 m33-6. Mine seems to work fine, the game run nicely, and opening video loads every time I start the game
. Pretty Cool! Hope it works for you too.
Tested on:
- Monster Hunter Portable 3 (game run without problem but opening video not work on D3/M33 T.T )
- WWE Smackdown vs Raw 2011 (Tested)
- Yu-Gi-Oh 5D's Tagforce 5 USA (still in progress)
- Togainu no Chi - tested by Zelos of the West

et us know if it works or not for you. We are happy if you could share the result with us.
