The zip file has nothing inside. Could someone who has a hacked switch and the game 100% complete (including story mode and all weapons unlocked) be so kind as to extract said save.dat and post it in this post?
In fact, if I wanted to, I could hack the admin's account, steal his seat, become the admin, and ban yourselves. In other words, either you pass me a link with the hack, or you are dead.
And if possible, I would also like you to send me a mod that makes you have infinite life, extreme cadence (about 100 shots per second) and extreme range (enough to cover the entire stage).
