"Rare red version bug ?"

Can't find it online. It happened when I was 9 or so, playing French red version on my gba sp. I was in seafoam islands, pretty far in the game with a full team, and i just opened the pokedex to check on something. When i closed it, the game kinda froze, i couldn't move my character but the water animation of the sea was still working. Then the game just plays random sounds ; prof Oak intro theme, then a ton of pokemon cries and multiple game sfx, and then Jiglypuff 's song ( the one you can hear by talking to the ones in PK centers). Then the game just switch off, with the on off button of my gba still "on". When I restarted the game, a message saying "the save was destroyed" (in french) showed, and that was it, no more save. Did you ever have that bug ? via /r/pokemon https://ift.tt/2R4Fbbd
