I completely agree with you Daniel. The line between C64 and C65 mode is really a case of which version BASIC you see when you load the program. After that, it is completely irrelevant. Given the lack of C65-mode software library and bugs in various versions of the C65-mode ROM, I suspect that the default will be for MEGA65 software starting in C64 mode. But also agree that it would be nice to see some software that starts in C65 mode, or at least that takes good advantage of the VIC-III/IV features etc.
