I beat book 1 - 3 of Shining Force CD at Super Hard. Still the only really challenging battles were the final battles of book 1 and 2. The lack of a time/round limit and the ability to revive dead characters cheaply make the Shining Force games too easy. Also you always have money galore.
It's a good game, but overall I enjoyed Shining Force 1 + 2 more.
I played the game on the mega drive mini 2 (without savestates or in-game save scumming).
There's a hidden 4th book, which consists of only one battle, but alas I wasn't able to find the item required to access it. Since book 4 is a secret bonus that's not mentioned in the manual or story, I consider the game beaten by my standards.
