I played magic knight rayearth pretty much beginning to end in one sitting with zero issues. The load times were amazing actually.
The saturn doesn't have an unused 12v rail like the dreamcast with cd rom removed. The early saturn units have 9v and later units had a 9v-12v which was used for scart switching.
Yup made me fall in love with the saturn even farther. I need to pick up a mega everdrive and an sd2snes now...
