Slash-N-Flash PSP

From GameBrew

Last Updated2007/08/18

Slash-N-flash is a generic flasher which can flash whatever files your heart desires. It is aimed to make the process as simple and user friendly as possible.

It was one of the contest entries for the Neo Summer Coding Compo 2007 (PSP Applications).

User guide

How to use:

You can flash anything from individual files neatly organized as you wish (through the folder named folders), all the way up to entire themes also organized as you wish.

You can also save precious flash space for themes (through the folder named themes) with the click of a button - backing up your files as well.

Several examples are provided by the author (as well as tutorials in the readme).

Note from developer:

It is strongly recommemded that the first thing to do when you start the program is to go to Tools> and back up your Flash0.

If you plan on using the Theme function of this program, make sure the data.txt included in your themes are made accordingly.

The data.txt's currently included are only meant for 3.52 M33 (It should not cause bricking your PSP instead an error message would appear).


This is for any Custom Firmware version. However the theme files included are intended for 3.52 M33 only.
