Not sure if this has already been discussed or not but I couldn't find the information when I looked for it so I thought I'd post my findings for others.

I personally would like to be able to use the maemo file browser to browse my selection of roms and simply select a rom and have it open the appropriate application. To do this is very simple. You have to have root access in terminal (install rootsh).

Open a terminal and type

We are going to edit defaults.list

The following step is optional to make a backup file
Open defaults.list with your favorite text editor and add the following lines at the end of the file:

Save and close the file. The first line associates .nes files with Ines and the 2nd line associates .gba files with VGBA. I didnt add a line for the snes emulator because when I tested it, the emulator would launch but would not start the game.

You can now click on an nes or gba rom from the maemo file browser and it will launch the emulator and start the game.

I assume you could add similar lines for the GB and MasterGear emulators but I dont have those installed so I cant give instructions for them.

Hope someone finds this useful

hey, there is a typo, its not default.list its defaults.list

computers cant reason you know, need to be precise

also please add in a line that says

and wrap all your commands in code wrapper

to launch vim to edit the files use

Okay, i just have to rewrite the guide all together, it ait very newbie friendly. Copy any thing of it to the first post.

This is how to make NES and GBA games open in the file-browser:

Short versions for people that are well known with linux:
Insert
at the bottom of
/usr/share/applications/defaults.list

Long version for Newbs:

First of all you need rootsh to do this. Get it here (note if your in the maemo browser you can install it directly from that site):
http://maemo.org/downloads/product/Maemo5/rootsh/
this is a shortened url that you can use to type into the maemo browser:
tinyurl.com/rootsh

You need to find the X-terminal if you know how to do this, go a head and open it, if not here is how. Open the main menu, at the desktop it opens with the button at the top left of the screen, press it again if the application switcher appears. Press others, and chose X Terminal.

in here type these commands
this step is required for noobs, it backs up the file you are soon going to edit.
Now you need vim installed, this command does not hurt anything if you all ready have it install.
press y or yes on the keyboard if it asks

now we are going to edit the file
now we are inside vim, i dont really like this text editor because its hard to navigate and do stuff, ill walk you through it, do this on the hardware keyboard.

press the right and down button multiple times till your at the end of the document. When your at the end of the last line press the "o" button, this is o for Oscar (dont hold shift while you do this).
Now press the Linebreak key, the enter key that is. And write in this

its important that these lines are on two separate lines, and for simplicity sake we put them on the bottom of the text file.

now press the "esc" button on the bottom of the screen and now we need to save properly. to do this simply write

and then hit enter.

This should work instantly, start playing!

Could we get the above script modified to open MAME roms, please? Thank you.
