Version 2.0.0 - June 28, 2024

Improvements

• Added support for multiple MEGA65 models including the 2024 batches aka R6; currently we support R3/R3A, R4, R5, R6

• Added support for additional bi-directional Expansion Port signals

• Increased robustness of HyperRAM

• Support for the MEGA65's I2C architecture

• Support for the MEGA65's real-time-clock

• Two more 60Hz screen resolutions: 4:3 480p and 4:3 800x600 and one 59.94Hz screen resolution: 3:2 480p. Implemented by a more elegant aka dynamic video clock reprogramming.

• Better HDMI compatibilty due to switching to the Tyto2 framework and due to fixing an audio bug

• More robust reset handling: Cores start in reset state and the firmware is un-resetting the core when time is ripe

• The power led indicates a long reset by switching to blue

• Run/Stop now has a global "go back" semantic: It either closes an open window (including help screens or file selectors) or it goes back one menu level when the user is in a sub-menu.

Bug fixes

• The "Audio improvements" feature only worked with analog audio (3.5mm jack) but not with digital audio via HDMI

• Fixed a crash in the file browser

• Fixed missing ".." in folders created with certain macOS versions

• Fixed Run/Stop propagation bug when closing the OSM

• MEGA65's internal floppy drive kepts spinning when a floppy was inserted.

Version 1.0.0 - June 21, 2023

Commodore 64 for MEGA65 version 5 is based on this version 1.0.0 of the MiSTer2MEGA65 framework.

Version 0.9.1 - January 28, 2023

Works with more HDMI monitors, frame grabbers, HDMI switches, etc.

MiSTer2MEGA65 was not compliant to section 4.2.7 of the HDMI specification version 1.4b: It did not assert the +5V power signal. Now it does assert the +5 power signal via the FPGA pin ct_hpd.

Version 0.9.0 - January 9, 2023

After being in development since April 5, 2021 while being in a constant "alpha state" with continuous changes and refactorings, Version 0.9.0 is the first stable version of the MiSTer2MEGA65 (M2M) framework.

The first production quality core that is based on M2M is the Commodore 64 for MEGA65. Additionally there is a work-in-progress Apple II core based on M2M. The main reason why we are currently using "Version 0.9" (0.9.x) for the M2M framework instead of "Version 1.0" is that there is not enough documentation available, yet. If you have a look at the MiSTer2MEGA65 Wiki then you will notice, that there are many gaps in the documentation.

This should not discourage you from using the MiSTer2MEGA65 framework right now to port MiSTer cores and other cores to the MEGA65. You can use the source code of the Commodore 64 for MEGA65 as your "user's manual" and "reference handbook" for the M2M framework; additionally to the existing Wiki pages.

For being able to actually use the C64 core's source code as your documentation of how to use the M2M framework, we added a tag calledM2M-V0.9 to the GitHub repository of the Commodore 64 for MEGA65. The tag is necessary, because Version 4 of the C64 core was based on an earlier version of the M2M framwork and only from the tag M2M-V0.9 on the C64 core is aligned with Version 0.9 of M2M.
