Great work!

That's still under construction but here is the Pcsx_rearmed Leste wiki link:

What about porting RetroArch?

As previously mentioned, RetroArch works fine already but 'generic' cores like Pcsx or Picodrive or Snes9x are to heavy for N900. They need a lot of optimisation and specific settings to work properly and most of the time, that's not enough unfortunately.

Pcsx_rearmed is available in Extras repository now.

It works 'out of the box' but user config file ownership must be modified to be able to save custom settings:

As root:

That's it. See wiki for more details (I'll try to add more stuff soon).

DrNokSnes is also available through Hildon Application Manager now.

GUI is still broken but the emulator works fine from command line:

So it is still a work in progress.

I'll try to add a wiki soon.

Note: it can only work on armhf devices and it has been only tested on N900 at the moment.

By the way i'm not sure it is useful or necessary to build it for arm64 since Retroarch should work fine on most 64bits devices.

DrNokSnes is now fully working with his GUI.
The main issue was -again- config files and wrong parameters in the desktop file.

Here is bomberman which works in the vm but on the droid 4 it is not centered. I have no really time to fix it.
I already fixed automake and libtool. So it can be compiled just by

debhelper (>= 4.0.0), libgtk2.0-dev, libosso-dev (>= 1), libsdl1.2-dev

But debian files should be also updated, I increased only compat level from 4 to 5.

Maybe someone likes to play with the code.
