m68k has been saved.

Software solution to a hardware problem The quick solution would have been a composite out for your computer.

The m68k backend is at risk of being dropped from gcc release 11. It uses some old conventions, and needs to be updated.

Tricks like this are commonly used back to the NES era ...

You can try addr2line with the generated .elf file and that PC address. Verify with a debugging emulator, use the memory view and see what asm is at the pc address.

The linker script puts code first, then rodata. It's very unlikely for you to ever have 2mb of code.

"load ROMs quickly for development and debugging" -> both have an usb connection for that. ARM is just a detail.

And the second UMDK and Mega Everdrive x7.

Well yes, GOAC + output mixer + glue would be cheap to make, however the total market for any expansion is low. Even for official Sega ones.
