v4.7b1

Licensing:

• All files of the core emulator, except reSID, are now dual-licensed. In addition to the existing GPL license, they are licensed under the Mozilla Public License v2. The GUI code is still published under GPL only (#777).

Enhancements:

• Added a new menu option for simulating the execution of a BRK instruction (#773).
• Memory can now be read or modified inside the RetroShell debugger.

Bug fixes:

• Fixed a bug in the CPU reset routine (#778).
• Fixed a bug that prevented some snapshots from being restored when a cartridge was attached.
• The CPU’s processor port values were not written into snapshot files.
• PET strings extracted from P00 files got the wrong padding character (#769).
• The CIA inspector panel always shows the contents of CIA 1 (#779).
• The saved dot mask setting did not get restored on startup (#775).

Internal changes:

• Large data structures are now created on the heap rather than the stack (#811).
• In debug builds, debug variables can be switched on and off dynamically in RetroShell.
• The internal run loop has been simplified.
• CIAs are now executed by the event scheduler (like in vAmiga).
• IEC bus updates are now triggered via events (#766).
