thanks to TigerKnee for informing that isozone database was moved to retrozone.co
I made sure to grab wizardry chronicle, empire 1, empire 2, gameboy versions of empire 1 and 2 (completely different from the PC versions), and prisoner of the battles and wizardry asterisk and the ps1 remakes of wiz 1-5. oh, also the gameboy (not color) wizardry gaiden 1-3 games. I've actually never bothered to play through them.
i recommend grabbing whatever obscure shit you're not sure you'll be able to easily download when/if retrozone goes down too.
EDIT: speaking of also need to go download the Sega Saturn version of wiz 1-3 remakes, as supposedly the Saturn versions have an extra dungeon floor and I've never played that content. the gameboy color ports of Wiz 1-3 feature additional items, around 15 new items, and also feature an extra floor. I don't know whether the extra floor on any of these ports is 1 single floor added to each title or if it's one secret floor hidden inside only one of the 3 titles; i only know that such extra content exists due to reading japanese wikis.
