No, there isn’t an option for that, well maybe de OWSE(dev) at the bottom, I looked at it and it seems you can mod the map (npc, pickups...) I didn’t tested it, but maybe it can

I'll screw around with it with Sun, already randomized Moon. XD

I hate to double post, but I'm having an issue with the randomizer and the person who made just like... completely ignored me. I tried to randomize TMs, and it went through in the randomizer, but the game didn't accept the change. I checked my updates and I have no updates for Sun or Moon in my DLC list. Any ideas?

if you do have a clean copy of your folders, just randomize TMs again and copy/paste the garc

I figured out the problem. I was getting my folders mixed up because they all looked the same. So what I thought was the randomized code.bin file was actually the backup one I copied over by accident. *facepalm* At least I figured that much out by myself. I do hope they find a way to add field item randomization. I like the randomized shops, but I actually found a shop that was selling the Master Ball for literally nothing before I even took on the first trial. lol

To avoid that in the future, check the timestamps of the garcs. The one PK3DS just edited will be the most recent....

Okay, I'm trying to patch a JP game update with a translation patch and I still have no idea how to work this. Using Luma's innate patching lags my game so I'm trying to get a prepatched .cia running.

Image here is what was told in the translation's own post but I have no clue what this means either.

SciresM and co. are able to get into it to make their PK3DS work, but I figured I can too since I have a .3ds file. I can't decrypt it though, so I decrypted a .cia. That doesn't extract correctly...neither does the .3DS since it just crashes before it is about to extract the romfs...I don't know...

Despite my best efforts I can't extract and .3ds files. I'm trying to extract the files for a decrypted fire emblem awakening .3ds file and it runs and ends instantly with no files extracted. Is there something that I'm doing wrong because I sure as hell can't figure it out.

yeah the extracting doesnt work for ultra moon, i can extract the original moon easily and can randomize it too, but NOT with ultra moon, maybe the rom is not good i dont know. It just says extraction done in 1 second without creating any files.

    ooowwww a new way for me to beat NFS 510 :D @SylverReZ

  • SylverReZ @ SylverReZ:
    @AncientBoi, Yeah, believe you can do PSP games as well. But a Pi5 is much powerful in comparison.

  • Psionic Roshambo @ Psionic Roshambo:
    Not sure about other models of Pi4 but the Pi 4 B with 8GBs OCed to 2Ghz handles PSP really great except like 1 game I found and it is playable it just looks bad lol Motor Storm Arctic something or other.
  • Psionic Roshambo @ Psionic Roshambo:
    Other games I can have turned up to like 2X and all kinds of enhancements, Motorstorm hmmm nope 1X and no enhancements lol

  • Psionic Roshambo @ Psionic Roshambo:
    I will admit that one does seem more interesting than the usual Ambernic ones, and I already liked those.
  • Veho @ Veho:
    I dread the price point.

  • Veho @ Veho:
    This looks like one of their premium models, so... $150 :glare:

  • Psionic Roshambo @ Psionic Roshambo:
    To me that seems reasonable.
  • Psionic Roshambo @ Psionic Roshambo:
    I mean since basically all the games are errmmm free lol
  • Veho @ Veho:
    I mean yeah sure but the specs are the same as a $50 model, it's just those pesky "quality of life" things driving up the price, like an actually working speaker, or buttons that don't melt, and stuff like that.

  • Psionic Roshambo @ Psionic Roshambo:
    I think all in my Pi 4 was well north of 200 bucks 150ish for the Pi 4 the case the fancy cooler, then like 70 for the 500GB MicroSD then like 70 for the Xbox controller. But honestly it's a nice set up I really enjoy and to me was worth every penny. (even bought more controllers for 2 or 4 player games.) hmmm have never played any 2 player games yet :(
  • Veho @ Veho:
    Yeah that's what I hate about the RPi, it's supposedly $30 or something but it takes an additional $200 of accessories to actually turn it into a working something.
  • Psionic Roshambo @ Psionic Roshambo:
    yes that's the expensive part lol
  • Veho @ Veho:
    I mean sure it's flexible and stuff but so is uremum but it's fiddly.
  • Psionic Roshambo @ Psionic Roshambo:
    Yeah a lot of it I consider a hobby, using Batocera I am constantly adjusting the collection adding and removing stuff, scraping the artwork. Haven't even started on some music for the theme... Also way down the road I am considering attempting to do a WiiFlow knock off lol
  • Veho @ Veho:
    I want everything served on a plate plz ktnx, "work" is too much work for me.
  • Veho @ Veho:
    Hmm, with that in mind, maybe a complete out-the-box solution with all the games collected, pacthed and optimized for me would be worth $150 :unsure:
  • Psionic Roshambo @ Psionic Roshambo:
    Yeah it's all choice and that's a good thing :)
