- Added a 68K interface, CPU/68K/M68K.*. - Moved Turbo68K source files to CPU/68K/Turbo68K. It is no longer used but is being retained in the source tree for now. The LSR instruction has not been fixed in this update. - Changed sound board code to use the new 68K interface (and hence, Musashi). - Changed version string from 0.2-WIP to 0.2a-WIP. This is still an alpha version. - Above changes have broken the 68K debugger.
