Does somebody know how this works for NES application?
Issues:
- I don't know where the application is, I've been searching over mobile, var, etc.
- If Im going to modify permissions, is it at a ROM level or at an application (NES) level?
Thanks,

- I don't know where the application is, I've been searching over mobile, var, etc.

The aplication path may depend on your fw version. For 1.1.4 it is in /Applications/NES.app and in 2.0 in my case it is in /private/var/stash/Applications.xxx/NES.app

- If Im going to modify permissions, is it at a ROM level or at an application (NES) level?

Execution permissions are for the application (nes level). For the roms the only permissions needed is to read wich is the default so you don't need any further.

Someone knows how can i see why an app crashes in 2.0? since it can't be lauched from the shell i don't know how to check that, even with gdb is hard in case the app crash at the beginning because i don't know the proccess pid.

cool, i plan on developing soon and im sure this will help
