Igir won't recognize my discs.

[rvanlaar]

I'm using redump.org dat and have dumped a few discs.

Two are on redump.org:
edde9ca68158edd60fa727c8126d5266e495106f
6142e012de32c95f73a880fa2f0f8f470af645d4

RomVault does recognize both, but igir doesn't detect them.
Here's the csv output:

,,UNUSED,test-input/Loewenzahn (Germany) (Rerelease).bin,false,false,false,false,false,false,false,false,false,false,false,false,false
,,UNUSED,test-input/Opera Fatal (Germany).bin,false,false,false,false,false,false,false,false,false,false,false,false,false

Command used to for this:
npx igir@latest copy zip test report --dat IBM\ -\ PC\ compatible\ -\ Datfile\ \(52848\)\ \(2025-06-10\ 13-36-19\).dat --input test-input/ --output output

I've found the problem. My cue sheets have a different checksum because of line-endings differences.
My .cue sheets have /n line-endings, the cue sheet on redumper has /r/n.

Here's the relevant output from the redump.dat:

        <game name="Loewenzahn (Germany) (Rerelease)">
                <category>Educational</category>
                <description>Loewenzahn (Germany) (Rerelease)</description>
                <rom name="Loewenzahn (Germany) (Rerelease).cue" size="121" crc="ae5d4567" md5="d1dc7cb77d84eeff77ec5f2ce7e8e078" sha1="e8faed5db6b43324ca3b0841ace54304a15d6f4c"/>
                <rom name="Loewenzahn (Germany) (Rerelease).bin" size="722028720" crc="3c7f7232" md5="82c5c4fceb636aab498e86813155f35d" sha1="edde9ca68158edd60fa727c8126d5266e495106f"/>
        </game>

When I add the cue sheet from redumper next to the .bin. Then igir finds the game.
Is it correct that igir won't do anything with a game when it finds only a partial match?

Correct, unless you provide the --allow-incomplete-sets option. This is different from RomVault's default behavior, as incomplete sets may give a false impression that written files are 100% playable as-is.

Note that if you're using Redump's Dreamcast DATs, you may also be encountering #1577.
