put the files in the A folder into the root folder next to boot.id and data folder
use a desktop that is lower than 4092, 4817 works good and put it in your Release-W7-Yaca\EmuDisk\Partition2 folder
when game starts press F1+F2, you might be able to just press F1
Go to the game's sub test menu and turn off drive motor, and card reader if you are not going to use the card system.
F1 - test
F2 - service
you might have to wait on black screen for a little bit. it takes a short while to load.
