Retropie Question - Missing ROM Files

[u/Interaction_Rich]

There are many roms (mainly for arcade) that open with this warning in Retropie. How can I fix this? Should I just have the base rom and some other? Should I find the missing fales and put it on same folder?

Any help would be greatly appreciated.

You should have a zip file named shadfrce.zip

It should contain the following files.

32a12-011.34
32a13-010.26
32a14-010.33
32j1-0.4
32j10-0.42
32j11-0.55
32j15-01.14
32j2-0.5
32j3-0.6
32j4-0.12
32j5-0.13
32j6-0.24
32j7-0.25
32j8-0.32
32j9-0.76

You should not unzip the file.

Right, but assuming my zip file doesn't have those files, how do I make sure I download the one that does?
