Re: Question regarding pak saves

The N-Rage way worked for me, you probably just had to change mpk to n64 in the file browser, it's a dropdown.

This might be easier though. It's a mempak/dexdrive reader. Not exactly user friendly but it works. Drag over the .n64 file and open the JS console (Ctrl + Shift + K), and type in extract(0). It'll save the contents as a file and you rename that to whatever your ROM is named. [Old pic]

EDIT: Improved version of the tool above. It's a full-fledged controller pak viewer/editor.

Though for extracting SRAM/EEPROM saves, you'll have to strip off the first 32 bytes of the exported notes, to work in emulators etc.

OH MY GOD !! I emulated DK64 to see it , but then I put in my 64drive to believe it

Tsumi_to_Batsu_-_Chikyuu_no_Keishousha AKA Sin & Punishment. Japan exclusive game , I used extracted save on Zoinkity's translated S&P and works like a charm !!!

You sire are AWESOME !!!! Thank you so much for your kind work , I will be going to work for quite a while so expect to see me there a bunch 8-)

Welp .. I still have trouble with the pak saves .. so I decided to attempt that compilation of saves (I understand N-Rage now .. open .mpk then extract note)

Some of them the MEMCONV does not like ? As for TWINE it asks me some more stuff and then it hangs there

Gave another go at SF Rush , doesn't ask me nothing but the new file still comes up empty

First off, the DOS converter can't handle long file names, that is why it saves an empty file. Just load mpk / n64 files in N-Rage, save the saves you want in each one as .a64 files, then Insert them all into the save you want to compile into.

Sweet works great again

The SRAM/flash saves are not working in 64drive .. I load up my Paper Mario or JFG and just doesn't detect although filename are one and same

Perhaps this is the "endian-swapped" bit I somehow must do to them

Do a search for "Command-Line Package (Neill Corlett)". The dude's site went down, but you can still find it. It comes with a bunch of useful utilities, one of which is byteswap, and it does what you want. You'd run it like this:

Code: Select all

byteswap -s 4 filename.fla
This would change the endianness from little-endian to big-endian, basically "wordswapped". The -s 4 part is important because it specifies that 4 bytes be swapped, which is how flash and sram is typically saved from emulators.

It's too large, probably has a header on the beginning.
You can generate a new S&P save and compare it with the downloaded one to see where the "real" data starst, and chop off what's unneeded.

There is indeed a 32 byte header when exporting notes (544 - 32 = 512). This is to allow note files to be importable into other MPK files. It was made to be a general editor for Controller Pak dumps, so i didn't see a reason to add "Export without the note header" option.

All you need to do is delete the first 32 bytes in a hex editor like so: http://i.imgur.com/dnjzu61.png

The 32 bytes represent the raw "Note entry" data - the game code, publisher code, game name, extension etc.

Bring back the old one o.0 As it's not broke really whatsoever

I don't know if it's that I may have all the native saves I need/want ..

Cheers
