Okay, so I was patching a patch from Noitora. I was patching a .UPS patch with tsukuyomi to a clean, un-trimmed ROM. I chose "Apply patch to an existing file", browsed for the UPS, then the ROM, and the clicked Apply Patch. Then came this box: To directly patch source file, a temporary file is being made. Upon successful patching, the target file will be replaced with this. Applying patch file 'C:\(Private sorry, destination is correct though.)\xs1.ups' ... Reading file 'C:\(Private sorry, destination is correct though.)\Xenosaga I & II.nds' ... Target file is 'C:\(Private sorry, destination is correct though.)\Xenosaga I & II.nds.utm' ... Patch application will take approximately 1 minute(s), 4 second(s). Please be patient ... UI will not be responsive during this time. Failed! Input checksum is invalid. How do I fix this? I tried to "Apply Patch to A New File" and I triedto bypass the checksum validation, but I got a corrupted file. Help please?
