The new 2024 MEGA65s (aka R6) can recieve the reset signal due to R6's improved hardware. To be tested if the FCIII already works better on R6 MEGA65s even without a C64 core improvement.
Seems to work on R6 boards: https://www.forum64.de/index.php?thread/125676-c64-core-f%C3%BCr-den-mega65/&postID=2159280#post2159280
Symptom (1)
Final Cartridge III hardware cartridge starts into BASIC instead of starting into the FCIII main menu.
Tested with HDMI: Flicker-free ON and OFF. Behavior of the FCIII does not change.
After that, to start the FCIII you need to do the following:
And then it works.
Symptom (2)
FCIII starts into a "blue screen" (empty screen with standard C64 colors).
In this case you need to repeat "RESET on the FCIII" and "RESET on the MEGA65" multiple times until it works.
Important fact
In general, the FCIII is not able to reset the MEGA65 at all on R2, R3 and R3A MEGA65 machines. This is due to the MEGA65's hardware architecture: We simply cannot "receive" any reset signal. Daniel Mantione pointed this out on Discord, quoting him:
About this issue
It is not sure, yet, if we can ever have a stable bootup behavior for the FCIII. This issue is about to investigate this and in case it is fixable, then to fix it.
