MEGA65: add support for $D613/$D614 doing direct keyboard matrix scan #228

Closed lgblgblgb closed 3 years ago

Let's add support for $D613/$D614 doing direct keyboard matrix scan.

For now, let's add to 'hmw' branch as well to allow open-rom to run sanely (since it relies on VIC-IV features which are not there yet in the base Xemu branches).

Done for "hmw" already.

Maybe need some clarification about these registers: https://github.com/MEGA65/mega65-core/issues/356
