For both Yakuza Kiwami and Yakuza 0 you could use CoSMOS to find the value of that heat eye bar during the car chase so that you can always slow down time. If I remember correctly there are 5 addresses with the same value and I froze them all. You just need to search first for an unknown value, then use the heat eye option in the game so you can search for a decreased value... let it fill a little then search for an increased value... let it fill to max and then search for unchanged values also helps - just repeat a bunch of times.
I also used CoSMOS to get CP for all the gambling games. Here it was easy to find the initial chips (for example 25000 at the beginning of that particular game) then win or lose some and search for the new value.
gamepass version is posted.
different yakuza games are coded differently, and have different engines. may not be possible to have identical trainers, etc.
