I tried out #node-virtual-gamepads (https://github.com/jehervy/node-virtual-gamepads
).

#ioctl syscall crashes with #ENOTTY after I select 'gamepad'.

but we'll call this 'promising'. probably will be easier to add #gamepad support to #uxnemu than to try to wade through the levels of complexity to get #squeekboard to behave nicer under #SDL (it tells me unknown keyboard layout sometimes at compile)
