1. BizHawk 2.11 + NesHawk + ROM tests + published TAS (made on FCEUX 2.2.1 and console verified)
Duck Tales (U)
https://tasvideos.org/UserFiles/Info/638999211879456402
- Desyncs at 1st level after falling bridges due to extra lag frames.
Changing input can reduce loss to 1 lag frame. If you insert 1 frame (
already added in the following movie file) of L after falling bridges, the next desync point is at f14202, a mountain goat giving us lag frames

Changing input can reduce loss to 1 lag frame after mountain goat, but desyncs again because of different mountain goat height.
Fixing the Y pos of McScrooge to accomodate, desyncs at an ice platform.
Duck Tales (U) (Prototype)
https://tasvideos.org/UserFiles/Info/638999215917156503
- Desyncs at 1st level due to lag frame at f1130
- Requires different input at starting the game (S, L, S). Need to check if P2 can press S earlier
Duck Tales (J)
- Syncs the same as FCEUX 2.2.1, however desyncs at African Mines because of longer japanese text
Duck Tales (E)
https://tasvideos.org/UserFiles/Info/638999218285905707
- Desyncs at 1st level 1st enemy, however it loads the game 1+1 (lag) frame faster.
- From TCRF: The European version increases Scrooge's movement speed in an attempt to compensate for the lower framerate of 50 Hz televisions. As a side effect of this change, Scrooge can just barely jump over the large gap in the second part of the Amazon without assistance from Launchpad.
2. African Mines zip fail
https://tasvideos.org/UserFiles/Info/638999218829781966
There are only 3 identical places with snails and the zip doesn't happens, no matter the gap between the stair wall and the snail.
I assume it's either the size of the enemy or the size of the wall is too small.
3. 1st level rolling boulder + Wall zip fail
Tried it but the game doesn't pushes McScrooge inside the wall
https://tasvideos.org/UserFiles/Info/638999286434153940
4. Other parts of the game (past African Mines in japanese and The Himalayas past ice platform on U2 resync) doesn't syncs up,
List of remaining potential places for applying the WhiteHat94 zipping glitch to theoritically save time:
- The Himalayas 1st mountain goat + gap between us (Probably will get stuck inside the wall because wall is too high)
- The Moon moon zip (Probably 10-20 frames slower than current strategy)
- And for reminder, Europe version might have a potential if it has a different horizontal speed in scenarios where U/J fails
5. Made a single test on Duck Tales 2 (posted it in it's thread) but seems like the glitch is fixed in that title.
