Subject: Update the mouse demo to run with the new mouse API that uses loadable
X-Git-Tag: V2.12.0~543
X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=4e81c529d9035eaa1aed011d6f58fac7d9b7eb78;p=cc65

Update the mouse demo to run with the new mouse API that uses loadable
drivers. Remove Atari support because there are no loadable drivers for
the Atari.
