Now swap your new sprx, rename it to audioplayer_plugin.sprx (Ready to make a trigger that will call a Core dump) then run a game in bd-emu or original disc, later go back to XMB (The eboot remain in memory) and trigger the Core dump by trying to play any mp3 stored on usb with the modified audioplayer_plugin.sprx.
The sprx don't use much memory because this they are great to something like this(Documented on the SDK)...
I will try to do this because i have the 3.70 SDK...
Sounds like a nice work-around
I think it's worth a try.
