SKARDAVNELNATE: There appear to certain files that gogrepo isn't downloading correctly. One is from Starpoint Gemini 3, another is from Chernobylite. I download to one folder then import to another folder as a form of verification. After a dryrun there's regularly one file from each game that is still marked for download despite being present. These are .bin files and running the installer also treats them as missing. Downloading these in my browser gives me files that both import and install.
Okay just checked Starpoint Gemini 3 and it seems fine to me. The GOG.com list is fine, md5 data is available for everything, all files download, the files verify both in gogrepo and internally, and they install fine. If you want to send me a PM we can talk about the issue here, as I suspect there's an MD5 issue here and I'll need to get the md5 of the file you're having issues with and ask for the matching information from your manifest.
gogrepo has a built in verifier that I would recommend using over your system, and gogrepoc remembers already verified files which makes things much quicker for ongoing maintenance.
