Is there a way to know what CRC32 checksum of the file to be patched an UPS patch expects?

I wanted to patch Mother 3 (CRC32 42ac9cb9) with the Spanish translation at http://mother3spanish.blogspot.com but the patcher at https://www.romhacking.net/patch/ reports a checksum mismatch.

I had this same issue myself today. I wrote this quick Python script which outputs the expected CRC32 checksum: https://github.com/rarenight/find-ups-source-checksum

Any chance you’d share the script again?
