It should. When a thread is marked "multi" it should work in US, EU and beyond, with the caveat that each game is unique in how it handles CUSA codes and each geographic region can have more than one CUSA code. But the Yakuza / Like A Dragon series at some point switched to being multi-region so it doesn't surprise me at all to see this one tagged that way.
From what I understand these (and other) saves now only work on PS5 when uploaded to PS cloud on a PS4 or when importing on a ps4 save of your own (same as a reregion).
Just a heads up for the people without a PS4, if you need a PS4 save, as soon as the game starts you will get your first trophy - before you get the chance to create a new save! So if you mind a 1% game, either find a way around this (by not syncing?), or get ready to use the set to also plat the PS4 version.
¡Hola amigos! Lamentablemente, esta partida guardada no funciona correctamente con SaveWizard. El juego se actualizó recientemente y estos archivos están dañados. Intenté exportar e importar los datos en modo avanzado, pero sin éxito. Los archivos en la PS5 parecen estar dañados. La única opción que queda es copiarlos a una PS4 y luego subirlos a la nube. Es una pena porque ahora mismo no tengo una PS4, pero de todas formas se agradece. Probablemente compre una PS4 en el futuro, así que guardaré esta partida para usarla más adelante.
It does work.
I'm assuming you are on a PS5 didn't read the thread. Resigned savegames can only be transferred to a PS4, or have to be imported into one of your own PS4 saves in advance mode.
