There is a small problem on the X68000 disk drives boot order. If you have loaded any floppy image before, you quit the game, and then you are trying to play any HDD games it will not be loaded, because the floppy disk was not properly ejected as Retroarch remembered what you have loaded previously by default. This could be fixed by turning OFF the “Save Disk Paths” in the core option.
Also as reported earlier the PC-9801 emulator np2kai is broken on the Odroid Go Advance since mid-February.
Here is the bottom part of the log file, hope to see a fix soon :-) Thank you.
