In this video, I test what happens when I download play CTGP-7 and what happens when I join a CTGP-7 lobby with an unpatched cartridge. The results were surprising to me, especially with the unpatched cartridge. The game doesn't care that they're different tracks, it just slightly desyncs. Even if you go way out of bounds it doesn't crash, kick you, or anything. Please excuse the bad narration, I had just woken up when I recorded this and nothing was prewritten.
