Train Dupe Glitch Explanation - ACGC

TL;DR Taking advantage of travel data with a blank memory card. Actions of gyroid face player are overwritten with blank memory card travel data that has my actual player data on it. Those actions were the contents of the bank account however the map data is not overwritten, AKA, duped bells.


How this glitch works is I'm taking advantage of travel data on a blank memory card. So I save my "player" data onto a blank memory card when at the train station then I take out the memory card so I'm only left with the "gyroid face" player as you see. So now my actual player data is on that blank memory card that I took out and now I withdraw a bunch of bells from the bank account and drop them on the ground. After I'm done emptying my bank account and dropping all the bells I save & quit then put back in the blank memory card that had my travel data on it then load my file again. This time I'll be arriving back on the train where I last left off my actual player. The villager beforehand says that anything that was done after traveling will be erased; AKA anything that the gyroid face character did will be overwritten with my actual player data. This is true. All the actions of the gyroid face player have been erased and overwritten with my actual player data that was on the blank memory card. So my bank account is back to how it was before leaving. However, the map data has NOT been overwritten. So now I have a bunch of bells on the ground that were dropped but my bank account has not been effected. This is how I can just keep duping bells over and over using this method and it is the fastest way to make bells in this game using glitches.


Quick guide on how to do it:

NOTE: You must have already paid off all your debts since you need the bank account unlocked to do this glitch

- Have 2 memory cards; 1 is your main save file, 2 is a blank memory card or a memory card without any AC data on it
- Talk to Porter and say you wanna take a train
- After finished saving, reset the game or just wait to get on the train, either way you'll end up at the title screen
- After that take out the blank memory card in slot B but still keep your main save file in slot A
- Launch the game ignoring all the "warnings" the villager gives, you'll have a gyroid face since your travel data is on that blank memory card and you left it behind
- Start emptying your bank account and drop as many bells as you want on the ground
- After that, save & quit then put back in the blank memory card in slot B
- Launch the game ignoring all the "warnings" the villager gives, you'll arrive back in your town on the train and the actions that the gyroid face player did are overwritten but the map data is not
- Pick up all the bells and deposit them all
- Cycle can repeat again
