Si los descomprime ... pero necesitas un prx que venia en el anterior psardumper de helldashX , hay que sustituirlo por el que viene .... sacado del redme :
Attention: HelldashX prxs violate Sony Copyright, so they are deleted from my homebrew (that now uses old prxs by M33).
To make RSPsar Dumper compatible with 3.80 and 3.90 Eboot you have to use HelldashX's prxs (take pspdecrypt.prx from HelldashX's 3.80 Psar Dumper release and put them in RS Folder overwriting existing pspdecrypt.prx).
Note: If you use HX prxs, you have to be conscious that you're violating Sony Copytights!!!
PD: Este psar dumper , dumpea directo al pc...necesitas el usbhost.exe ejecutado y el eboot en el mismo directorio ...
