auto-load cassettes and floppy in current RetroArch MAME (v0.223) ?
Under system "Tandy Color Computer" the following system media can be added and they just play fine:
coco_cart
dragon_cart
I can also can add additional system media and DIG find its cover thumbnails, which is great too:
coco_flop
dragon_flop
dragon_cass
But when I execute them I get the following message "Sorry this file isn't supported by MAME/MESS".
Actually this message isn't true because the current MAME v0.223 should auto-load these too.
I use only RetroArch 32-Bit as the 64-Bit sadly hasn't got any late MAME on it.
Why does DIG only load cartridge files fine?
