That's weird, this is the first case I hear that someone gets its game bricked just by resetting some values to their default values. I'm pretty sure something else went wrong.
Like what? When I injected the file with the color changes. The town hall told everyone to wake up, and set the time back a few hours, and then when i saved and exited, i could no longer get in game. I fixed that issue, but everything was still missing.
The only other time this happened to me is when I accidentally put 3 beaches..not knowing you couldn't do that. But i deleted the acnl.bin and mori that contained that error amd restored from before I did that. I have been using the ram editor almost every day and nothing has occurred except when I changed the colors. If all else fails, I can just order most from the catalogs and start over.
