Well, the RPGCodex itself, (well, Richard and Helly basically, though I'm doing my best to join that pantheon of translators), have translated:
- Wizardry Gaiden 4: Throb of the Demons Heart (SNES).
- Wizardry Empire 2: Legacy of the Princess (Windows PC).
- Wizardry Chronicle: The Promised Land (Windows PC).
- Wizardry Empire (Game Boy series; seperate from the PC series, but same devs).
Other than Codex-translations:
- Wizardry 6 port on the SNES was English-translated years and years ago (much better than the original DOS release).
- Wizardry 1, 2, 3, 4 and 5 ports for PS1 all come with official localization (change language to English in options menu). BTW, the PS1 port of Wizardry 4 is the only other existing version of the game aside from the Apple II release. All of the PS1 ports are content-identical, however 4 and 5 received additiona of optional Auto-Mapping.
- Wizardry Gaiden 6: The Prisoners of the Battles (again, comes with built-in options to change to Eng-language. Game itself is a Wizardry 1-3 clone, and it is amazing).
I'm currently translating Wizardry Empire 1 for Windows PC, and have just received word that a kind soul will try to translate the NPC dialog. I already have everything else in English except for the dialog.
You could say, without any sort of hyperbole, that the RPGCodex is the best thing to ever happen to the Wizardry series.
BTW, since I want to keep on-topic: if you find the time to give one of the Wiz titles a try, I recommend either playing the PS1 port of Wiz 5 for hard-core traditional Wizardry, or alternatively play Wizardry 6 which features a healthy mix of old-school Wizardry mechanics combined with the burgeoning designs that the new series "leader", Mr. D. W. Bradley, began implementing.
As for Wiz 6, either of the two existing versions if just fine: DOS release and/or the fan-translated SNES port. Both are content identical, but since you value graphics so damn much I say definitely go for the SNES version.
Simply look at the beautiful sprite art:
Here is DOS Wiz-6:

Here is graphics from Wiz 5 on PC:
