Nice interview @SmokeMonster!! I couldn't agree with you more, the HAS is the only indispensable piece in my setup. It really unlocks the hobby.
Paired with some DS multis, you've got yourself a really stable, versitile, easy to use arcade experience. For the newbies looking here, it's worth the wait.
Coming from Games with Issues
Is it possible to press “select” button with HAS Supergun? I mean mapping some joypad button to pins #26/#d ?
Is it’s possible to have a PDF copy of the manual in order to study HAS Supergun features beforehand?
