This is true (the royalty varying on the size of the memory) but the royalty was also significantly higher if there was any custom hardware involved on the cart - specifically because you actually had to purchase the "Game Pak" from Nintendo, so they would charge you "whatever they could get away with" for enhancement chips.

Any idea if Enix was locked into buying the Game Pak already for Star Ocean by use of battery-backed SRAM or not?

All the game paks (aka cartridges) were manufactured by Nintendo. By selling a licensed game, they were already locked in.

So it's just a question of "was the S-DD1 priced cheaper than another (or larger) ROM chip by Nintendo" right?
