Mario Party 7 (GC) - JP Trailer (Game Rip) (4K60 Upscale)

This is the 4K60 (not AI) upscale of the native 640x480 .sfd interlaced Japanese trailer for Mario Party 7 for GameCube, that was included in the Gekkan Nintendo Tentou Demo 2005.11.1 GameCube demo disc. This was ripped from the disc itself alongside all the other .sfd trailers in a singular .tgc file. I used a cmd function to change the tgc file into a .gcm file, and then used GCIT to open said .gcm file to extract all the .sfd files from it. As with any .sfd file, I converted the file into an audio-less .mkv (optional, I just prefer it over .mp4) file with Handbrake, and using the SFD to MPG Converter, I was able to get the audio as an .mp3 (all seem to be 192kbps) and .wav file. This time I'm opting for the .mp3 file as I guess it's the most "true" file (.wav is lossless but much bigger and I'm curious if it's even factually better?). Anyway I merged the two with Avidemux, deinterlaced it with Yadif, and added 32px black borders on the side to make it the correct aspect ratio when upscaling it to 4:3, then do said upscaling to 2880x2160.
