Found a bug with MirageOS (v1.2) where it glitches when renaming stuff. And so I did exactly what no one else would do: I played around with the bug until I got something more serious, and now I've corrupted my archive with no backups at all

I can't boot my calculator anymore without using CLEAR+ON (it flashes a random screen for half a second, then disappears). If I disable the archive with that CLEAR thing, the calculator seems to work fine, so it's probably only some part of the archive that's corrupted, not the OS.

But I lost about 12 projects in group vars. Most of them are small, and I could probably get back to where I was in those projects in a few days, but Contra, XDE, PapiJump, and Ultimate Falldown were all really far in (Contra in particular already had a nearly complete engine with enemy AI and aiming that I'd just added in the past few days), and it would take a long time before I can get all of it coded again.

So here's my question: Anyone willing to give me directions on how to get as much of it back as I can? I've never really done anything with Flash before, except some simple reading. I haven't GarbageCollect'd or done anything else to my archive since the crash, so the data should still be there, but some of it's definitely corrupted. Thanks in advance for any info!

Sorry to hear, but I doubt you can recover them if this is this bad. Just hope that your calc isn't completely broken.

Did you make a RAM clear ?

I don't think that would help, considering his calc can't boot without ON-CLEAR. My calculator had the same problem about 2 months ago, and I had to reset the entire memory (archive+ram).

Sorry to hear, but I doubt you can recover them if this is this bad. Just hope that your calc isn't completely broken.

Yeah, it still works, thankfully And all my apps are still there. It's just that since I have to boot with CLEAR, all my archived/grouped vars are hidden.

what do you have in your ram?
anything inportant?

Did you make a RAM clear ?

Yeah, of course. I clear my RAM at least a dozen times a day anyway, so I don't care at all. What I'm trying to do is recover all my projects from the archive.

@graphmastur: I once managed to get EVERYTHING from a corrupted archive. HOW? I don't know, I crashed my calculator and when I turned it back on it was good So, it was a random day, a few days after getting it corrupted. It was a random occasion.

That's not a corrupted archive. If your calculator still works, it's only your RAM that got messed up, and after a RAM clear the RAM's set back to default. I do that just about every day too

Well, I guess an asm program could be written to make all the flash pages valid.

I don't know how... What makes a flash page "valid"?

Flash pages are mostly for apps

Flash is all the memory the calculator has that's not RAM. It's used for the OS, apps, and variables. The reason my apps are still there is because I used TI's CLEAR+ON boot, which only searches for apps in the archive.

All other flash variables are not added to the VAT, and that's why they're gone from my memory list. They're still physically there in the flash memory, just "hidden" in a way.

And so basically right now some of my flash pages are corrupted, and that's why I can't boot normally, but I don't know how that works.

Ok.

Can you link the calc with the PC after a RAM clear or the link is still btoken ?

What do you mean by RAM clear? My link's not broken, though.

usually when the RAM is corrupted you cannot link it to the computer ( it's detected but you can't transfer data ). So if you reset your RAM it should work and then you could backup your files.

It's not my RAM that's corrupted. I corrupt my RAM every day It's the archive that's corrupted, and I don't want to reset my Flash, because then my groups would definitely be gone.

On a related note, my calculator crashes every time I RAM clear now because it tries to boot normally afterwards.
