Question for The Legend of Zelda: Majoras Mask

I got a glitch on the Majora's Mask cartridge where I was unable to learn the new wave bossa nova and that glitch even persisted after erasing the file. At the same time as I got that glitch, the kafei anju sequence also became corrupted and the man from the curiosity shop would not appear in kafei's house even if I did the rest of the kafei anju sequence before that properly. As soon as I caught the 7 zora eggs and deposited them then got the time stopping glitch before jumping down, then cancelled it where the cutscene of the eggs hatching occured, both that cutscene and the bossa nova cutscene would play and the game stayed uncorrupted even after erasng my file and the kafei anju sequence also became uncorrupted at the same time. A few months later, the bossa nova cutscene became corrupted again but this time without the kafei anju sequence being corrupted and it still won't uncorrupt after I erase my file. Again I got the time stopping glitch where the hatching cutscene occurs after depositing the eggs then cancelled it before that cutscene and was able to learn the bossa nova but unlike last time, it only gave a temporary solution and the game became corrupted again after I erased my file. Can anyone find a gameshark code to permanently uncorrupt the ability to learn the bossa nova so that I can learn it again even if I unhook the gameshark. I did pull out the ocarina as a zora and not as another form. The zora hatchng cutscene was never corrupted, only the bossa nova cutscene was.
