4 seeders
4 seeds means it’s not actually a dead torrent. Slow uploading sure, but not dead. I’d suggest just leaving it alone, if it’s going at 8% per week it should finish on its own in roughly 13 weeks assuming the speeds don’t change much. That’s going to be a while but once you’ve got it you’ll be seed number 5 as long as you keep seeding it on your end.
If I can find find the exact releases of as many roms as possible in the collection from other singular sources, can I resurrect this torrent by just copy+overwrite into the unfinished folder?
Sure that may work in theory. Just keep in mind you’d need to find tons of ROM files that are exact bit-by-bit matches of the files in the torrent - otherwise overwriting mismatched data into your currently downloading torrent would make things slower for you since you’d now have to re-download that data to get back to 8% or whatever.
EDIT: Looks like you lucked out, congrats seed #5 :)
More likely those seeds are super-busy so it just takes a while to keep a consistent upload. these type of seeds tend to be on a ton of other low seed torrents. So any new seeds helps.
And of course there’s the seeds that just don’t have great connections e.g. could be a laptop that is literally only online x hours a day or even week, or they can only upload at night or whatever.
