Thug 1 fixing modded park checksum?

Hi guys,

I have been trying to stack and merge objects in thug 1 in a hex editor, like we can now in thugpro without hex editor but i still like the thug 1 editor more. But the problem is i can't load the park back in thug 1 cause of the checksum is invalid. Anyone can help me how to fix this in the easiest way what the process is for that? I looked already at various things like: http://tnthps.us/filesystem/xbox360/noj ... ewtab.html I thought this would go for thug 1 too but i am not sure how to rehash / resign a file cause it still can't load if i do it this way without rehashing. Also looked at this: http://thmods.com/forum/viewtopic.php?f=6&t=12 But that is confusing to me like i don't know where to start with that.

So any help would be appreciated :)

It's basically a crc32 checksum 1's complement of the data from the checksum location to the padding (the i's).

Yea i did some researh and found that it was a crc32 checksum, but i thought the checksum always was at the beginning of the hex data. So here is the park i modded with some stacking and stuff, is the last 8 bits then the checksum? Sorry i am still struggling with this.
