Issue with save

[ZTD09]

So, I'm replaying some classics and I ran into a problem with DK64. I've been using the in game save exclusively with the exception of a single save state where I saved right before the second boss. (I believe I saved under save state 1.)
Now, later that day I saved, all was normal. I had 25 bananas. The next day, I played some more. Everything loaded fine, I made it up to the factory, got up to between 35 - 40 bananas, saved and quit.
Now today, when I loaded up my game, I had nothing. No save files, nothing. All three spaces were empty. I played around with the settings a little, didn't change anything, just looked to see if anything said something about saves. Then I went over to save states, and loaded up my save state right before I fought the boss. Now, at the time I had 10 bananas, and when I exit then load my game now, it reverts to an in game save that I did a little while before, where I had 10 bananas. I'm not exactly sure what happened, but I'm trying to recover the save where I had 35 bananas, or at the very least the one where I had 25. Can somebody help? :/
(Also, if anybody has a save somewhere near the beginning of the Factory that I can use, that would also be much appreciated.)

Something like that happened to me once (on DK64 too ) I never have played it since

Where was your old save at, and do you still have it? If it's further than mine I may ask to use it if I can't find a solution to my problem. :/

I don't think I have it any more, but I had around 125 bananas and had beaten the final boss.

Dang. Anyone else able to offer any help?

If you're saying the native EEPROM save file got overwritten with corrupt data by Project64 that caused an inability by the game to read the progress from it, thus reverting to the defaults with no game save data imported to the RAM etc., then unfortunately the game would had to have overwritten the corrupt save data with that emptied data, so unless you have a backup of a working EEPROM where data loaded into the game I don't see how it can be recovered.

If you ever got a "failed to load EEPROM" message then maybe that might have something to do with it.

Other than that the only recoverable data is from backup saves like the saved states you did.

I've never heard of this happening with DK64 though...did hit "Save" in the menu a couple or more times in general though, dunno if that made a difference.

[ZTD09]

I didn't get any error messages, my save just literally up and poofed. :/

Then it got corrupted somehow, but I've never heard of Project64 itself corrupting the save data. So I wish I could tell you how that happened in the first place....

But once the file is overwritten you can't recover a past form of it unless you did a backup.

Darn. It's really, really odd. :/

It is really odd. I could only guess some other software process interfered into conflict with the file, or maybe you changed the RDB game save type settings randomly one time.
