I downloaded multiple different Mario Kart Arcade GP 2 (USA).iso from archive.org. After exporting the files with dolphin, I compared them and found that files\tpl2_E_sp_ROUNDsel03_RR.tpl is different. One of the crc32 checksums is D7F29B6C, and the other is B30631D9. I am a little confused now. Don't know which one is correct.
