On the song selection screen, press both fx and select Valkyrie Mode or s - Critical.
If it is confirmed, Valkyrie dll is applied. Use a sub-monitor at 120hz or higher.
Is it correct to change to the G version? It seems that soundvoltex.dll is not applied. Press f12 to check the frame. If it is fixed to 60hz, it is in the F version.
If the hz is not correct, it will not run and only a white screen will appear
