@Tak - top man, well done and thank you for investing the time.

Did you try esd for sound? Is there even an option for that on MAME?

Is the build available for download and testing?

- I'd love to try it with the gamepad.

Have you tried Defender with sound? There's just enough buttons on the gamepad (4 way dpad, 4 "fire" buttons, 2 hard to press shoulder buttons) to assign one button to each function.

Is there by any chance a "show the screen sideways" option in MAME?

Thanks very much,

Martin
