Default GUID Database
A place for creators to post the blocks of GUIDs they used, are using or intend to use.  This is listed in hexadecimal, contains 256 characters, and each GUID is 8 digits.  ie:  0x001E8300. For details about downloading SimPE, see The SimPE Preservation thread.

If you are a casual creator and do not expect the need for 256 GUIDs, then you could just use Random Byte Generator, or hashing via SimPe's Hash Generator.  The odds of a conflict are slim.

Any existing blocks, from any time, can be listed. Full, empty, in progress.

My intent is to update the table in this post and delete any posts claiming blocks to keep the thread tidy. If you see responses to this post, then please read them and ensure the block you are claiming comes after.  I've started this with blocks I claimed right before the database went down the last time. 

I've found the table feature in the forum to be a bit unwieldy, so I've moved the database to a Google Spreadsheet.

For those who need a crash course in Hex for GUID blocks:


0x is the prefix, and these don't change. The bolded numbers (shown as 1 through 6 here) are the GUID block and should be the same for all 256 GUIDs in a block. The last two (7 and 8 here, just to show their position) are the changeable numbers. They'll be 00 through FF.

0x12345600 (first)
0x1234564A (random in the middle)
0x123456B1 (random in the middle)
0x123456FF (last)

GUIDs are in Hex, which means there are 16 numbers, so you can think of it as all the decimal numbers from 0 to 9 first, then A to F, then the decimal numbers, then A to F, etc.

01 to 09, then 0A to 0F
10 to 19, then 1A to 1F
...[skipped 20 to 8F, they follow the same pattern]
90 to 99, then 9A to 9F
A0 to A9, then AA to AF
...[Skipped B0 to EF, they follow the same pattern]
F0 to F9, then FA to FF
And you're done with the GUID block.

The numbers do continue from 100-FFF all the way up to 10000000-FFFFFFFF but those aren't need-to-know for the GUID block. They do follow the same pattern, though. Ca be useful to know for other things.

EDIT: Added a handy notepad document with a full 00-FF GUID block that you can use to make a list of used GUIDs (with instructions on how to use).

I found a few GUIDs in some objects, and it looks like they were part of GUID blocks (hadn't noted them down anywhere, could be from a couple or so years back when the SimPE register was briefly back up), so perhaps best to put them on the list.
