[quote="reprep"]Hi,

can you please summarize your tweets about 3DS CFW here too? People like me are interested in those but we can't understand because of language barrier. Thanks.[/quote]
It's very easy.
I just want to make better CFW.

Relocatable ELF (Plugin) loader, Better signature check of CIA (support both enrypted and decrypted one), Allowing kernel access from homebrews, enabling exception display for debugging, debugger plugin(ctrlink?), screenshot plugin...
When I say such a hope, Japanese PSP developers also dream of that.
But, there is no source code. We must reverse it.
Why don't they release their source code?

        sum -= delta;
