Beta 18:

Sprite emulation update test version.

- sprites were visible when they were outside of DDFSTRT/DDFSTOP range (which really is DDFSTRT - end of line, another undocumented feature) "Fixes" demo Blittersweet (looks more broken now but it does look exact same on real A500) This update may not be 100% correct yet, it can break other programs. Test and complain
- some archives mounted as a harddrive crashed
