Try Recovery, hide corrupt icons
I did, but I found that a bit annoying. Using pspBrew_091 I was able to merge the two eboot.pbp, so there is no longer a corrupt icon.
You are using the version .1 not the .2 of the program .............. just install the .prx file like normal in the .2 package?
It's neither .1 or .2, those both have an eboot.pbp and iop.prx. The one I used shipped as leda.prx and game.txt, the prx is much larger than the iop.prx.
I'm not really big on the details of the psp/vita scene, but from a quick google it's like the .1 & .2 are for psp and the one I used was ported to plugin for ecfw by neuron from the original dark alex version. Both .1 & .2 are much older & I have no idea how/if they would work on the vita.
If this tutorial was too complicated for you, just try with the included plugins 'P_LEDA.ZIP', 'P_CXMB.ZIP' and 'P_DAYVIE.ZIP'.
Open the archive and see how it is done - pretty simple.
I'm sure it would be simple if all their links weren't dead. It looks like I was lucky to even find any version of it that worked.
Even with the modbo eboot merged, I still need the plugin enabled for it to run. So if there is an updated version of it then a link would be nice.
