To play back TAS scripts on Yuzu, select the folder with scripts in the configuration menu below
Tools -> Configure TAS. The file itself has normal text format and has to be called script0-1.txt
for controller 1, script0-2.txt for controller 2 and so forth (with max. 8 players).
A script file has the same format as TAS-nx uses, so final files will look like this:
1 KEY_B 0;0 0;0
6 KEY_ZL 0;0 0;0
41 KEY_ZL;KEY_Y 0;0 0;0
43 KEY_X;KEY_A 32767;0 0;0
44 KEY_A 32767;0 0;0
45 KEY_A 32767;0 0;0
46 KEY_A 32767;0 0;0
47 KEY_A 32767;0 0;0
After placing the file at the correct location, it can be read into Yuzu with the (default) hotkey
CTRL+F6 (refresh). In the bottom left corner, it will display the amount of frames the script file
has. Playback can be started or stopped using CTRL+F5.
However, for playback to actually work, the correct input device has to be selected: In the Controls
menu, select TAS from the device list for the controller that the script should be played on.
Recording a new script file is really simple: Just make sure that the proper device (not TAS) is
connected on P1, and press CTRL+F7 to start recording. When done, just press the same keystroke
again (CTRL+F7). The new script will be saved at the location previously selected, as the filename
record.txt.
For debugging purposes, the common controller debugger can be used (View -> Debugging -> Controller
P1).
