are you 100% sure it's my rip (same music/title screen)? There was a legit standalone release with some differences, it's possible the original label just got missing/damaged I guess (I have one GBC cart from Taobao which came with a super blurry printout of the label cropped from a listing photo, but the PCB itself is original..)
Just curious tbh because the old dump is usually more common in generic bootlegs, since it's been floating around for so long.
