Turns out the game has quite a few difference between the SNES and Genesis version as well. I've played the Genesis version quite a bit and I thought I'd list them for anyone interested in reading about it.
The colors are roughly the same, but the Genesis version looks paler for some reason.
The music is disappointingly NES sounding, but the “supply port” music is actually better. It was nice in the SNES version, but it's so desolate, bleak and sad sounding while the Genesis version is more upbeat and happy.
The controls are a little awkward for when you want to look at your stats out at sea. You have to hold the A button then press left or right to either look at your crew's health, or look at your ship speed, etc. The map is also crammed with the save menu, so you have to select it after pressing start.
The supply ports are glowing red dots on the map now instead of all being the same.
Dueling is completely rigged in the Genesis version. It's possible to get a single move out of all 6 cards during your defense or attack turns. In the SNES version, you'd at least get one of each move. This applies even for the Crusader equipment.
