Ghidra SMS emulator remote debugger

Trying to do: https://wrongbaud.github.io/posts/ghidra-debugger/ but with SMS
Start with blastem, Ghidra 10+

Tried running in windows via: blastem.exe ROM_FILE.bin -D but I couldn't get ghidra to connect to it. not sure which option to choose.

Trying gdb via ssh.

Blastem's read me says

 Invoke an m68k-elf targeted gdb with
the ELF file. Once inside the gdb session, type:

    target remote | BLASTEM_PATH/blastem ROM_FILE.bin -D

Build 6800 gdb: https://sourceware.org/pipermail/gdb/2011-January/039404.html

I tried using WSL, but I forgot blastem needs guid, and doesn't run in wsl ( haven't figured out the wsl2 gui things).

stephen@Cube-Windows:~/source$ blastem romfile.bin -D

error: XDG_RUNTIME_DIR not set in the environment.
The path /dev/dri/ cannot be opened or is not available

Switched to vm

sudo apt insttal gcc
sudo apt install make
sudo apt install blastem

I think this isn't going to end well, since I think gdb is expecting ELF format, but they don't come that way. Blastem says

To use this, you'll want to configure your Makefile to produce
both an ELF executable and a raw binary.

Giving up for now:

Trying dbgengEngine locally:

with arguments similar to

blastem.exe ROM_FILE.bin -D

 But I think that debugs blastem.exe not ROM_FILE.bin

Maybe this isn't what I'm looking for. I think I want Ghidra to connect to a remote GDB stub, like is provided by OpenOCD: https://github.com/openocd-org/openocd/blob/master/src/server/gdb_server.c , maybe that way Ghidra can pretend to be GDB frontend and connect directly to blastem.

Probably something like: https://github.com/Comsecuris/gdbghidra
