I need to get my demo back on my computer, because my dad accidentally delete it on my computer, and I tried grabbing it off of here, but it gives me an "invalid/corrupted" message? Please don't tell me I have to do it all over again?:(

I'm pretty sure the link is busted. Get dome Data Recovery software. Sounds weird but it has worked for me when my family gets delete-happy.

Don't they only work if you never turned the computer off and on?

Now my only proof of anything is gone. Now people will think of me as an idiot who tells people bullshit again. WHY AM I SO UNLUCKY ALL THE TIME?

Isn't this the thing you're talking about? Downloads and extracts fine for me.

Computer recovery works regardless of if you turned it on or off. Why all the hate, your link most likely expired. If someone here did break your link on purpose, don't blame it on everybody. ;)

FAIL/10. Educate yourself.

When something is 'deleted' on a hard drive in most home operating systems, only the 'file allocation table' has a flag go up to no longer 'point at' the 'data block where the information is stored', it's thus seen as writable again.

Think of it as deleting a chapter from a book, by only going to the table of contents, and scribbling out that chapter's name. ;) (It's still intact, only now you don't know where.)


Unless you've done some read/write heavy work on the drive recently, the data's probably fully intact.
There is even software that can read sectors of a drive platter from 5 or more "full writes" prior on an actual data block, able to retrieve and reconstruct data. It's a bitch, but it's possible.


Relax. Nobody's out to get you.

That file itself is already corrupted, and is that the plain vanilla version, or is it my hack of it where I added all the parallax scrolling and the gazillion sprites moving around onscreen?

It is the latest version I could find in your thread (link (http://www.sega-16.com/forum/showpost.php?p=138429&postcount=80)). I don't know which other version you'd be talking about, since I didn't really follow that particular thread. If it's the first version you need, that one downloads and unzips fine for me as well.

Also, what Knuckle Duster says is truth. I've managed to recover quite a few 'accidentally' deleted files and even crashed hard drives that way.

That is the right one, I have no idea why it's not downloading right on my computer.

make ALL sprites bounce off each other on colission, or have some uneven sinusoidal movement or smooth bouncing action going on...

Could be a few different things, logically I'd look first at a problem with your web browser via some corrupt/malware/useless plugins or BHOs being installed. Or maybe a broken-firewall lockdown on certain file extensions.

Did you go so far as to MD5 check the data integrity?
You may need a fresh install of your compression utilities if it's passing a checksum.

That sounds reasonable, since my dad deleted all my stuff when he was updating the firewall.

I tried getting my demo back using recovery software, but not even that was able to find it.

Common, do you have anyway of sending me that back without the zipped file, like through an email or something?

I've just sent the unzipped file to the e-mail address in your account's contact info. Hope that works.
