Running OpenMSX on OUYA

Cool, thanks for reporting!

You could of course bind the command main_menu_toggle, which pops up the OSD menu, to something else (like a button of your controller). That might be a tad easier

Thank you Manual for the hint. Had to do some research, but I found it.

Here is the howto for future reference.

1. Start up OpenMSX
2. Press Y on the controller (this opens up the console)
3. With a keyboard attached to your OUYA, type: bind 5 main_menu_toggle
4. Close the console with Y

Now you can use the L1 bumper button to open the OpenMSX menu.

(If you would like a different button for the menu, these are the buttons and corresponding keyboard characters)
5 = L1
6 = R1
7 = L2
8 = R2

I can confirm, that my Android gametablet uses the same keybindings for the bumper buttons as my OUYA. I have to do a bit more research, but my guess is, that this is some kind of default configuration for keyboard emulating controllers within Android.

Also within other emulators they work out of the box, without I have to bind them, that makes my assumption of some kind of standard a good assumption

We are preparing a new openMSX release. I can set-up default SDL key codes for following controller keys:
A B X Y L1 R1 L2 R2 LThumb RThumb

Any recommendations? At the moment I'm thinking about:
A: WORLD_93 (mapped to firebutton 1 in openMSX)
B: WORLD_94 (mapped to firebutton 2 in openMSX)
X: WORLD_95 (mapped to console in openMSX)
Y: MENU (by default bound to command to toggle the menu)
L1: F10 (by default bound to openMSX onscreen keyboard)
R1: 6
L2: 7
R2: 8
LThumb: 9
RThumb: 0

if there are keys left over, what about a key for:
- ENTER (for some games)
- F1, F2, F4, F5 (for some games, mostly Konami... like Metal Gear and many others)
