So I tried running the genesis homebrew port of Cave Story on the Mega SD and I noticed a peculiar issue; there was no save feature. By this i mean the red floppy disc icon that allows you to save in game doesn't appear at all. It's not that the rom file doesn't have a save feature because it works on the Kega Fusion Genesis Emulator for PC. I even tried it on my Mega Everdrive X7 and the save feature worked there as well. Not sure what's causing the issue.
Here's a link to the rom download:
