No.20107 Robbbert Senior Tester Apr 28, 2022, 12:47	Tested reverting the suspected revision, makes no difference. Currently the game loads up to "COMPLETE" but then reboots, creating an endless cycle. The game is marked as MNW, so should we just close this?

When I tried to load the game and doing the steps above, it now hangs on an error screen with Japanese message that I'm not sure what it says. If anyone knows how to bypass that error screen, like to know how to get pass it.
No.22365 JimCarlTay Tester 23 days ago edited on: 23 days ago	For kollonc, you have to disable the BIOS Flash setting in the DIP switch menu after that notice pops up, and reset the system. There, the game will begin initializing. The parent set (kollon) causes boot loops after the game has finished initializing, so that's why it's not working.
