Aren't save states version dependent?

[vsub_]

Wasn't there some checking system.
Currently:
Creating a save state with 1332 is loaded without problem on 1161...an error appear but the state is loaded

Code:

Error: After "sceGe", found 20 (0x14) instead of save marker 66 (0x42). Aborting savestate load...

On 1319 no errors nor warnings and the state is loaded
On 1076 and below,the emulator crash with this error

Code:

Microsoft Visual C++ Runtime Library
Runtime Error!

Program:

This application has requested the Runtime to terminate it in an unusual way.
Please contact the application's support team for more information.

If I create the state with 1076 and try newer rev,then this error appear and ppsspp freeze

Code:

Warning
Error: After "RAM", found -1 (0xFFFFFFFF) instead of save marker 66 (0x42). Aborting savestate load...

Or if I create it with 1161 and use something newer

Code:

Error: After "sceGe", found 1 (0x1) instead of save marker 66 (0x42). Aborting savestate load...

and it's again loaded but ppsspp freeze on black screen if you try load something

There is already an info about the ppsspp version used to create the state in the save state file at 0x10,so why not ppsspp check there to see if the version match with the version currently running and if it doesn't,to not load the state
