Hacking the Visualizer_plugin.prx

after carfully looking through the visualizer_plugin.prx i have made some intereting discoveries.

1. I was able to extract this JPEG from the prx.


2. dont know how relevant this is but an obvious pattern (when changing these values PSP crashed when swithing visualizations)


3. values simalar to xmb wave hexedit


dont know if any of this means anything but its a start

randomly messed around...


thats it for now...

Please Upload this visualizer_plugin.prx

it looks cool

They are questions for experienced, it would is necessary to ask to Becus25 or Dark Alex.

Randomly editing PRX may show undesirable effects... Remeber... It's a prx like exe---they contain the actual native code the psp can work with...

Try the RCO instead.

++ For an original idea!

the visualizer rco doesn't have any model like the wave model in system_plugin_bg.rco or opening_plugin.rco it only contains the graphics of one of the visualizers and the thumbnails of the visualizers.
the rest seems to be rendered by the cpu but can be alternated thru the prx.

some attempts todo some predictable changes.




gnarr don't really feel like working on this...

that looks fiire

Does that mean PRXs donot need to be signed?!
That has awsome possibilities!

someone can explain to me how do this?
i don't understand a lot

hmm this is interesting i noticed the visualizer in 3.03 is different from in 3.40.... weird.... (im pretty sure they are both decrypted lol...)

since 2.71SE times ;o. DAX is using a bug (loadexec ?) to load SE/OE this also makes it possible load decrypted prx's.

no i didn't worked on it any further...
but the results above are done by alternating values in that area
0xD820 to 0xDB5F

Only one another thing, the offset in for the 3.04 prx?
