Hi and welcome all PSP owners all over the world

It seems that 5.50 GEN-D3 is buggy and people hate that, but anyway, everyone would still want to have the auto-decryptor feature and the speed up ms feature!

This is the right tutorial.In this tutorial, I'll simply help you fix 5.50 GEN-D3 bugs and add speed up ms feature!

This tutorial is divided into two sections

1-Fixing GEN-D3 corrupting savedata problem
2-Adding the speed up ms feature to 5.50 GEN-D3

First :
Fixing 5.50 GEN-D3 corrupting savedata problem


Instructions :



1-Download this homebrew app here
2-Extract it
3-Copy the folder named ' fix ' to ms0:/PSP/GAME/
4-Run it from Game-Memory Stick on your PSP
5-It should finish in seconds
6-Test your games , your savedata should no longer be corrupted
7-Enjoy then proceed to Step 2 xD
Second : Adding the speed up ms feature to 5.50 GEN-B2/D2

We're gonna simply add the 3.71 FatMsMod by Dark Alex to 5.50 GEN-D3

Keep in mind that 3.71 FatMsMod by Dark Alex has incompatibility with content browser mode of game categories , so if you use content browser mode with this 3.71 FatMsMod , all of your files in the categories in the ISO folders will appear as corrupted data

There's one for PSP Phat and one for PSP Slim ( with non Ta-088 v3 )

Note : If you have multiple memory sticks , then you have to add this line ' flash0:/kd/pegasus.prx 1 ' to the game.txt of each memory stick other than the one you used to install the fatmsmod , then reboot your PSP
