I'm about to start compressing my collection. I've had issues in the past with the files being corrupted during data transfer, so before I spend hours decompressing them all and then copying them over to my SD card to see if they are in-tact, I'd like to know if an application does this. I know there are apps that check nsp files for brickware, I was just wondering if I could use them to tell if they're installable or not.

nsp files don't compress much with the common compressors like 7-zip or rar. You might as well store them as is, it will save you time. If you're afraid they're gonna corrupt somehow during transfers to an external device, you could create an sfv file before, and check that they're ok after the transfer with it.
Now that I think about it, some guy here was working on a custom nsp compressor that had good results. Can't remember the name, but there is a thread about it here.

nsZip. It's what I'm using, but I just want to know how I should go about checking them after they've been compressed, because I intent to delete the originals from my hard drive to save space.

How does this work

sfv would be of no help if compressed with this nsZip app. It would totally change the checksum. You would have to uncompress before checking with the sfv file, which kind of defeats the purpose of compressing the nsp in the first place. nsZip would have to have an option to check the integrity of the archive, like 7-zip and rar offer. Maybe it does, I don't know, never used it myself.

You're thinking too deeply into this. I know I can't check the compressed NSPs, but I can uncompress them and make sure they weren't damaged during compression. I just want to know if there's a way to check the NSPs without uninstalling everything from my Switch and running them through an NSP installer.

Nsc builder can also
Check out information from a xci and nsp, including the Firmware needed to be able to execute it, the game info, the size of the nca content.

I'll check this out later, thank you

    i thought everybody knew cocktails are like 75% ice
  • Veho @ Veho:
    Yeah but not like this.
  • Veho @ Veho:
    It's not like they're complaining that their Slurpee is 99% ice or something, but if the cocktail calls for "shot of vodka, shot of vermouth, shot of gin, shot of Campari, three shots of juice, squirt of lemon" and ends up being a thimbleful of booze, that's a problem.
  • The Real Jdbye @ The Real Jdbye:
    the funny thing is cocktails in norway are only allowed to have 1 20ml shot of booze
  • The Real Jdbye @ The Real Jdbye:
    so..... yeah
  • The Real Jdbye @ The Real Jdbye:
    we're used to only having a thimbleful of booze
  • Veho @ Veho:
    Booo.
  • The Real Jdbye @ The Real Jdbye:
    same thing if you want whisky on the rocks or something, you can't get a double
  • The Real Jdbye @ The Real Jdbye:
    but you could buy as many shots of whisky (or anything else) as you want and ask for a glass of ice and pour them in
  • The Real Jdbye @ The Real Jdbye:
    it's dumb
  • Veho @ Veho:
    Maybe.
  • Veho @ Veho:
    There was a comparison of the number of Ibuprofen poisonings before and after they limited the maximum dosage per box or per pill (i'll look that up). No limit on the number of boxes you can still buy as many as you want, so people argued it was pointless.
  • Veho @ Veho:
    But the number of (accidental) poisonings dropped because drinking an entire package of ibuprofen pills went from "I need a new liver" to "I need a new box of Ibuprofen".
  • Veho @ Veho:
    Here we have ketoprofen that used to be prescription-only because of the risk of toxic dosages, but then they halved the dose per pill and sell them in bottles of six pills apiece instead of twenty and it doesn't need a prescription any more. Yes you can buy more than one bottle but people simply don't.
  • Psionic Roshambo @ Psionic Roshambo:
    Usually accidentally overdose of ibuprofen here is from people taking like cold medicine then ibuprofen for a headache and the combination is over what they need
