exeDSP patches.

Hello!
I wish to experiment some exeDSP patches (in memory).

I know game.so hooks directly to exeDSP but is there a way to do that from a userland program in shell?

(not from game.so) ?

I can mmap physical memory but since it's paged, I don't always find the same chunks of exeDSP in memory.

Any help is apreciated.

You can try injectso binary or gdb...
On B series it work, but on D none confirmed yet.

Nevermind. I coded a utility to patch exedsp on the fly :)

ok. glad to hear. Would like to see too :)

Perhaps you have some DRM dissable solutions for latest firmwares, where old way doesn`t work...

hmm.. I never looked at DRM routines. I prefer them to be encoded. And DRM decrypt just works perfectly.
