Hi, I got the game (sdvx 6) from https://nyaa.si/view/1397956 , then upgrade soundvoltex.dll to 20210616, following instructions...
the game cannot run, just gave me a black screen without any text
using geforce rtx 2060 super, maybe further settings required with gsync compatible display?
log.txt
the pc could run sdvx 5 without any issue, this time just black screen, no self-check text
