Is there a Metafortress patch for NTSC-J Kirby's Return to Dream Land?

I imported an NTSC-J copy of Kirby's Return to Dream Land (Hoshi no Kirby Wii, SUKJ01) for about $20 to play on my NTSC-U Wii. With both GeckoOS and USB Loader GX, I can only get as far as pressing 2 on the title screen before the game freezes on a white screen. After some research, I found out that this is due to the Metafortress anti-piracy/anti-tampering routine in the game, and I found patches (gameconfig.txt files, see below link) to disable it in the NTSC-U and PAL versions. However, I could not find such a patch for the NTSC-J version; does one exist?

I tried forcing each patch on the NTSC-J disc in GeckoOS and USB Loader; for example, I copied in the PAL patch but changed SUKP01 to SUKJ01. However, the game would not even boot with either patch. Disabling hooktype lets me get up to pressing 2 on the title screen.

Slots 236, 247, 248 are from when my brother had originally hacked our Wii years ago. I followed the cIOS guide at wii.guide/cios.

 

I solved my issue. I had downloaded Dolphin a week ago to try running it with a rip of my disc, but I didn't find out until today that Dolphin contained my solution the whole time.

In /Dolphin-x64/Sys/GameSettings, there's a file SUKJ01.ini that contains the NTSC-J Metafortress patch. I just had to reformat the .ini file's contents to make it compatible with USB Loader GX/GeckoOS (e.g. change "0x80175194:dword:0x48000084" to "poke(80175194, 0x48000084)"). And voila, now I can play the game on my Wii.

I guess I'll attach the NTSC-J patch here for the maybe single-digit number of people who need it...? I couldn't find it with just a Google search a week ago.

Edit: "with just a Google search" in the last sentence instead of "anywhere on the Internet"
