Sorry for this probably really dumb question, but I don't get it to work ._.

I was wondering how I can open the NSMB .idb Database with IDA Pro. If I just click "open" the files don't appear because they have the wrong extension.

(I feel like the noobest noob on planet ._.)

I dunno, check you are using the correct IDA version.

There are two IDA Pro versions, one 32bit and one 64bit. You usually get both when you install it.

They use different DB formats (no idea why lol). The NSMB db was made with the 32bit version, so try opening it with the 32bit version
