Would you mind adding your core to the offical MiSTer devel github. This will make apart of the offical project and will aid in keeping the core up-to-date as MiSTer changes. If your interested contact me on discord and I'll get you set up with the right people.
Fails to boot, resulting in green or black screen. ROM compiled from mame 0.213 using both Windows batch file, Linux script and Linux cat command. Others have reported the same issue. Maybe memory related, does it support 64MB memory card?
Shell script expects Linux/GNU "md5sum" command and output, so will show failure when built on macOS despite good hash. Suggest adding awareness of BSD/macOS "md5" command.
