M2000 v0.8.1

This version of M2000 is mainly a bugfix release:

• Feature: Added configurable low-pass filter (#129)
• Fix: Keyboard issue: hanging numeric "1" key in Windows (#128)
• Fix: CSAVE does not overwrite (#125)
• Fix: No screenshot written when filename extension is not supplied (#121)

M2000 v0.8

New in this 0.8 version:

• Save State feature to store M2000's current state (RAM + ROM + registers) to a single file and reload it at a later time. There's also support for quick (dialog-free) save-states by pressing Ctrl-C (quick save state) and Ctrl-V (load last saved state).
• Display-smoothing option, which makes the display look more similar to an original CRT monitor (i.e. less pixelated).
• Support for emulating a specific P2000T model: P2000T/38 (16K RAM), P2000T/54 (32K RAM) or P2000T/102 (80K RAM).
• M2000.cfg (editable) preferences file is created on initial startup.
• Nederlandse vertaling van het menu.
• Support for locked/readonly cassette files. When trying to CSAVE onto a read-only .cas file, you'll get the P2000 Geen stopje error message.
• After installation on Windows or OSX, all .cas cassette files are now automatically associated with the M2000 emulator. This means you can now just double-click a .cas file to open it directly in M2000.
• All file dialogs now retain the last openend directories.
• Control/action keys no longer use function keys, but are now defined by [Ctrl] + [Key]. E.g. use Ctrl-O to open a .cas file and Ctrl-R to Reset M2000. See README.md for an overview of supported control keys. Note that these keys also work in full-screen mode.

M2000 v0.7

After 26(!) years there finally is a new release of M2000 - the Philips P2000 emulator originally created by Marcel de Kogel in 1996-1997.

New in this 0.7 version:

• A completely new user interface with drop-down menus for Windows, Mac and Linux, which allows you to load cassettes and cartridges, save screenshots, change display size, and much more.
• The emulation speed and sound quality of the Windows and Mac versions has been improved dramatically.
• Fixed a lot of SAA5050 emulation bugs (thanks to @yqxq for helping to reproduce these issues)
• Uses "symbolic keyboard mapping" by default, which basically maps the keys of a modern keyboard to corresponding keys on the P2000 (as far as possible). The previous default "positional keyboard mapping" is still available as option.
• Support for emulating [ZOEK], [START] and [STOP] key presses directly from the menu.
• A few additional cassettes (Basic Demo Cassette zijde A and B) and an additional cartridge (Familiegeheugen 2.0 NL) are now included in the M2000 install packages. After running M2000, these will be available in the 'M2000' folder inside the user's Documents folder.
• M2000 now supports default file-type linking. That means that - depending on your OS - you can double-click a file with the .cas extension and then select M2000 as the default app to open it directly.
• Full-screen and joystick support for Windows and Mac.

Note that this will be the last release that supports MS-DOS.

Thanks to @yqxq, @ifilot and @dionoid for helping to keep the P2000T alive!
