4.3J Wii region error

Hi there, I am new to wii hacks. I got an unhacked wii from a friend and would like to hack it and play mario party 9.
my machine is at 4.3J with japanese UI.
I followed everything at wii.guide to install the following smoothly
letterbomb -> bootmii and hbc -> backup nand -> priiloader -> enabled region hacks -> install and configure cIOS -> loadergx + forwarder / wiiflow.
Then I download the game at wimm.net with wbfs format, and copy the game to usb stick using wiibackup manager.

everything is smooth until I boot into the game it will shows "region error!" message.

I used the below versions of softwares.
letterbomb -> 1GB SD card
priiloader: v0.9 -> 1GB SD card
(from wii.guide there is an option "region free everything" but I can't find this at the priiloader v0.9. I enabled all 3 lines starting with "region free" and I believe it is equivalent to "everything"?)
cios installer: -> 1GB SD card
(install guide following wii.guide/cios)
loadergx: -> 1GB SD card
wad installer: YAWMM -> 1GB SD card
loadergx forwarder: 5.1 -> 1GB SD card
wiiflow: v5.4.8: -> 1GB SD Card
wiibackupmanager: build78 -> at my PC
mario party 9: wimm.net with wbfs -> 8G USB stick

SD is FAT and usb stick is FAT32.

What should I do next? Please help! thanks a lot.
