ROM Hack Tomodachi Collection save editing research

[Ryccardo]

2 (alternating?) copies of the save at 0 and 0x40000

0x00020: Money in hex, 2(?) bytes, byteswapped

Warning: there is a checksum I haven't identified, so you can't just write FFFF there to get lotsa money

Could you explain that better?

could you explain that better?

As it is, it doesn't mean much anyway for the common person - if you open the .sav in a hex editor and go to address 0x20 (which by default is likely the start of the 3rd line) and byteswap the next 2 bytes, that's where the amount of money you have is stored (whether of the most recent save, or the previous one, in which case the most up to date money figure is at addresses 0x40020 and 40021)

The last part means changing that number isn't enough to change how much money you have (technically it is, but then the save will be rejected unless you change something else, at an address I don't know, according to a formula I don't know)

If you want to cheat, better to do so on an emulator with a memory searcher/cheat finder (if they exist at all for the DS) or at least a memory editor (no$gba), save, then put the save back on the original game or flashcard...

Is it possible to hack who is in love with who, or favorite foods?
