Got a favorite PSA whose attributes are vastly different than the base character? Well follow this guide and all will be well in SSE.
First open the PSA in a hex editor, such as HxD, which I'll be using.
I'm using SDoom's shadow as an example.
The normal attributes start at 0x80 and end at 0x360 so highlight that area and copy.
The size of the selection should be 2E0, like the screen below.
Now put the cursor at Offset 0x364 and Paste Write.
The paste should NOT increase the file size and should never go past Offset 0x644
Save. Test. Done.
All in less than 1 minute.
