Gaming Zelda: Spirit Tracks - .sav hacking

[AfterKat]

I've beaten the game once, but not with all the items. My flashcart says it has a 'dangerous' cheat to enable all items, but it doesn't appear to alter the quantity of treasures.

So far I've started collecting several .sav versions and have begun to compare their contents to try and isolate where information is stored, and where checksums are stored.

(Decimal character number (starting at 1), 4 hex numbers 0 indicating no change (usually), 4 decimal numbers, thoughts, hex address (0 start))

I've also written a C program using Wikipedia's pages as a resource to explain the algorithm and typical polynomial factors used for 16 bit crcs. All current permutations I've attempted have resulted in failure.

I'm starting to think I might need to run the checksum over a range other than 0x1c3c to 0x1c5b. Alternately seed it differently (0, 0xffff, and 'checksum' from the main segment), use a different set of coefficients (using LSB first: 0xa001 0x8408 0xedd1 0xa6bc 0x91a0 ), or something other than crc-16 style checksums.

I have also yet to experiment patching a valid set of items from one save in to another to see if they are still valid.

which cheat is dangerous to use?
well if you have beaten the game..
then just use it man

 

[AfterKat]

I tried it out; from what I can tell it doesn't actually /add/ any treasures, but instead seems to just enable the treasure's (unmask their existence).

 

[elixirdream]

hmmmmmmmmm
when you say it doesn't add any treasure?

what do you mean by that
are you trying to say it unmask by giving you the image of the 16 treasures but the amount is 0 ?

EDIT: the code i see in the database should give you 100 of each treasure

 

[AfterKat]

Either I'm not doing it right "All Treasures [SELECT]" is turned on, cheats are enabled... but I still don't see any effect. I even loaded my old game and pressed select.

-- edit --

Do I have to use a cracked, not clean, rom?

-- edit 2 --
My cheat db was the most recent one from: http://cheats.gbatemp.net/ but had a different version of the code for this cheat. I added the variation and have tried both... I am probably doing something wrong, but the simplistic 'select' instruction doesn't really tell me where/when I should see it...

 

[AfterKat]

Yes... I /was/ doing it wrong; I had soft-reset disabled. Enabling soft-reset along with use cheats fixed it.

http://gbatemp.net/index.php?showtopic=182028


AKAIO should probably have a bug report for allowing cheats enabled without soft-reset (at least w/o warning the end user).

Happy to hear that your problem solved
