| File | Description | Working? | Notes |
| 1ENCY3C | ZZT Encyclopedia Volume 1 | OK | Random Items only yields TORCH type due to perfect modulo-4 cycle limit, and Display Fixer fails to show unique GUI labels because ZZT Ultra erases labels completely. |
| 2ENCY3C | ZZT Encyclopedia Volume 2 | OK | All practical bugs/features implemented. However, there are so many useless exploits that ZZT Ultra does not try to emulate them all. |
| ADVLINK2 | Link II | PARTIAL | |
| AURA | Aura | OK | Too-rapid aura switching warps player to clones. This and other bugs originally present are reproduced by ZZT Ultra.
Also, in ZZT Ultra, this game plays REALLY fast on later levels (hard to get blue ending). |
| AVARICE | Avarice (SZT) | OK | The "Christmas tree" quad-direction blink wall only points up. |
| BOLETTE | Pepper Bolette | PARTIAL | |
| BEAUNASH | Sabotage | PARTIAL | |
| BRANDON1 | Legend of Brandonia | OK | |
| BQUEST* | Banana Quest | PARTIAL | BQDELTA.WAD is necessary to run Banana Quest. However, at this time, Banana Quest is still not 100%. |
| BURGERJ | Burger Joint | OK | Precise timing needed for episode 4; object alignment is hit-or-miss after the Jukebox dance (same as in original ZZT engine). Future PWAD patch recommended to fix this subjective alignment. |
| BURGLAR* | Burglar | PARTIAL | |
| CATCAT | Cat, Cat,
That Damn Cat | OK | |
| CHASEV12 | The Wild Chase | OK | |
| CODERED* | Code Red | PARTIAL | |
| CRYPT | The Crypt | OK | |
| CWARS* | Chrono Wars | PARTIAL | |
| DARBYTWN | Darby's Crazy Town | OK | |
| _DEATH_ | Death | OK | |
| DGATE | Death Gate | UNTESTED | |
| DM-GALRY | Dungeon Master's Gallery | OK | |
| DreamsDemo | Dreams Demo | OK | |
| DWOODS | Dragon Woods | PARTIAL | |
| ECCO | Ecco The Dolphin | OK | |
| ELIS_H_* | Eli's House | PARTIAL | Many unusual parsing cases |
| ENIGMA | Mission: Enigma | PARTIAL | |
| ESPFILE* | Evil Sorcerer's Party | PARTIAL | |
| EZANYA | Ezanya | PARTIAL | The sliding puzzle in the caverns is non-deterministic based on pusher iteration order; zap-cheating might be mandatory (true in original ZZT engine as well). |
| FANTASY | Fantasy Land | OK | |
| FLIMTOWN | Flimsy Town | PARTIAL | Need to research the full scope of technical hurdles for this file. |
| FROST1 | Frost Part 1: Power | OK | |
| FUZZYLUV | Fuzzy Love Horror | OK | |
| JACKYT | Jacky T | OK | It works. It's also insane. |
KNIGHT /
NEDEND | Ned the Knight | PARTIAL | There is board corruption in the NEDEND world file. |
| KUDZU20 | Kudzu | OK | |
| LANDING | Landing | OK | |
| LD38-QHK | QuickHack | OK | The "Tome Sweeney" cannot be read unless the original ZIP file is loaded, per ZZT Ultra's sandbox requirements for external files. |
| LEBENSRM | Lebensraum | OK | If POINTBLANKFIRING is 1, soldiers can shoot each other a lot more easily, and you can fight officers more easily. Not sure if this should be considered part of the game difficulty. |
| LEMMING | Lemmings Demo | OK | |
| LINKSADV | Link's Adventure | OK | |
| LINKADV2 | Link's Adventure 2 | OK | There is board corruption in the world file. |
| LINKADV3 | Link's Adventure 3 | OK | There is board corruption in the world file, which stops progress on the final red door and fight with Ganon. No editor can display these bad boards; logical end of game is assumed. |
| LST | Little Square Things | OK | ZZT Ultra has no performance delay, so it's quite tough on level 7 and against CraNKGod. |
| MACGYVER | MacGyver ZZT | OK | POINTBLANKFIRING must be 0. |
| MANOR | Mystery Manor | PARTIAL | It is highly recommended that you set KEYLIMIT to a number like 20. This game requires lots of tedious key-collection backtracking without any good reason. |
| MERBOTIA | Merbotia | OK | |
| MERC | The Mercenary | OK | |
| MGSVRM | Metal Gear Solid:
Tactical Espionage ZZT Action | OK | Bug in original game sometimes makes final sneak mission bridge uncrossable. |
| MOOSERIC | Mooseka Rules
with an Iron Fist | OK | |
| NYAN | Nyan Cat's
Adventures in NyanLand | OK | If POINTBLANKFIRING is not 0, Sharon Needles is easier to rescue. This is because the turrets "shoot" themselves. |
| PILATUS | Escape from Socialism | OK | |
| PORT037 | Portal ZZT Demo | OK | |
| PREPOSTM | Preposterous Machines | PARTIAL | |
| PRINCELY | Princely Conquests | OK | |
| PYRAMIDS | Great Pyramid of ZZT | OK | |
| RAYMBO | Captain Raymbo | OK | |
| SIVION | Sivion | PARTIAL | FYI: Password is 'BARNEY'. |
| SMILEY | Smiley Guy vs.
Dr. Z's Living Laboratory | OK | POINTBLANKFIRING must be 0 or else the giant bug just outside the laboratory will "kill" itself. |
| SYNDROME | ZZT Syndromes | OK | |
| SZZTE1A | Super ZZT Encyclopedia | OK | 3-D maze is glitched (same as in original Super ZZT engine) |
| VOMIT | Edible Vomit | OK | |
| VOYAGE | The Long Voyage (SZT) | OK | POINTBLANKFIRING must be 0 or else the Phoenix Mothership will malfunction. |
| WAR | War of ZZT (SZT) | OK | |
| WARLOCK | Warlock Domain | PARTIAL | |
| WAYNEAD | Wayne's Adventures | OK | |
| WINTER | Winter | OK | |
| ZPINBALL | ZZT Pinball | PARTIAL | |
| ZZTRIS | ZZT Tetris | PARTIAL | Duplicator occasionally "misfires" when creating piece. |
