Release 2.9

Update: v2.9: ACIA and Command line options!

Thanks to Steve Rubin, the emulator now supports ACIA communication through the command line! Like the VIA, the ACIA's address can be adjusted in the options menu.

Speaking of the command line, the first command line option has been added: -verbose. Use it to enable debug messages in the command line, which are now disabled by default.

That's it for this update. Remember to save new config files!
