Solitaire2021 new version V2.0 (fix)

Fixed a mouse driver issue with real hardware (it worked flawlessly in VICE). I thought I was clever and could save a few bytes but this backfired. The changes affect line 2090 and higher.

As a bonus I added a patch table so that you can now move the mouse driver to any hi byte * 256 address. This is useful if you want to reuse the mouse driver in your own basic progam but might want to reserve the $C000 address space for a different use. In that case just replace the "ad=" address value to a different address like for example $CE00 = 206*256 = 52736. The mouse driver itself is 215 bytes long.
