Describe the issue.

I've been able to successfully get the save from other battery backup games, and to dump the ROM for Star Tropics, but when I try to get the save I get a message "RAM SIZE 0k". I did verify that the cartridge and saves from way back in the day are working on a real life Nintendo, so the battery is not dead.

I'm not sure which revision of HW5 that I have but can update ticket if I figure it out. I did purchase premade OSCR from etsy fairly recently.
