having played for about 10 hours i finally finished the gameboy wizardry 1. i've only played the apple 2 version and that's what i'm comparing it to. the gameboy wizardry has map of 16x16 instead of 20x20. the gameplay is pretty much the same, with some new spells (ladalto), new monsters and new item, but they don't affect the gameplay.you can only kill werdna once for 50,000 ep & 50,000 gp from trebor.
the spells are more powerful than the apple 2 version.
triggering teleporter can end up in rock, but you can switch off the gameboy and turn it back on to start in a camp inside the rock, you'll then have to malor out before leaving the camp.
you can also backup your savefile into one of the 3 slots.
i'm not sure what transmigrate means though. if anyone knows please tell me.
