hey, so i got gamebatte and a bios but when i try to do the reset glitch it doesnt work because the reset takes like 3 seconds. does that have anything to do with the bios or now if so can someone send me a good bios ( i already tried the one under the tutorial video) and if it has nothing to do with the bios can someone help me

The reset is supposed to take 3 seconds, you are probably missing the 4 frame window to corrupt the save properly. Highly suggest to join the discord where more people can help you
