    3DS hacking and Pokémon survey for university

    EDIT: Because I got a lot of responses to work through, one of my tutors suggested I stop accepting them, so this survey's closed now. Thanks again to everyone who responded to it!

    Hi, everyone!

    I'm doing a research report for university, about the act of collection, how Pokémon was built around it, and fans' feelings about the shutdown of online servers for the 3DS. The survey deals with the topic of hacking the 3DS to use online functions on unofficial servers, and will help me determine whether the design of the games has given Pokémon fans a notable incentive to do this, once the games are eventually added to these servers.

    Since part of the goal is to see if a connection exists, your responses will be helpful even if you either haven't played the Pokémon games, or haven't hacked your 3DS.

    The survey should only take about 5 minutes at most, and all responses will be anonymised. I'll be accepting responses over the next two weeks.

    You can take the survey here.

    Thank you in advance!

    PSA Pokedit / Cake trashed my 3DS, sent to Pokedit.shop for CFW & this is what he did to my 3DS console

    I always felt uncomfortable and uneasy about soft modding my 3DS with CFW, so Pokedit.shop felt like the perfect solution, he would do it for me and I wouldn't have to worry about messing up my console, my thinking was send it to the "professionals" and nothing could possibly go wrong, clearly I was wrong. I went for the send-in option, I ended up paying almost $144.90 + $19.90 for return shipping to PokEdit on top of the shipping I paid for to get my 3DS to him for something I could have done for free had I gotten out of my comfort zone and this is what he did to my console for what was supposed to be a SOFT mod.

    He damaged my back cover, completely detached the screws from the backcover (They are designed to be loosened, not removed). There are also now deep scratches on my 3DS that were not there and a HOLE in the shell that absolutely was not there cause I take care of my stuff. How someone can treat other people's stuff like that is beyond me. He completely trashed my 3DS and I am extremely saddened by it. I can't believe I was considering sending more consoles to him, so glad I waited till this one arrived first.

    Don't be like me and don't send your 3DS to anyone for CFW, just do it yourself, even if you feel uncomfortable. I regret sending my 3DS to him, my 3DS was so special to me, it even has a capture card installed by Loopy who took great care of my console for a HARD mod, yet pokedit damaged my console when all he was asked to do was a softmod.

    Just sharing my experience so this doesn't happen to anyone else, don't overpay for something that you can do for free, save your money and do it yourself

    [PSA] Help us save SpotPass features from the online shutdown!

    As you may know, Nintendo announced that 3DS and Wii U online services will be discontinued in April of this year. This includes SpotPass services. Many titles like Mario Kart 7, StreetPass Mii Plaza, the Pokemon games, Super Mario Maker, and others used it to distribute content to users.

    The problem

    With the closure of the 3DS and Wii U online services, SpotPass features will stop working in many 3DS and Wii U titles.

    The solution

    The SpotPass Archival Project has been started to collect users' SpotPass caches, which contain data from recent SpotPass events in games you've played. This allows various network revival services to archive the SpotPass data ahead of the servers' closure, allowing SpotPass features to be replicated later and re-enabling functionality in countless games after the closure of the official servers.

    Sounds great, how can I help?

    If you want to learn how to contribute the SpotPass cache from your system, visit the website of the SpotPass Archival Project: https://spotpassarchive.github.io/

    If you need help or want to hear about updates on the project, join the SpotPass Archival Project Discord server: https://discord.gg/wxCEY8MHvh

    Helper script I made that runs binmerge and chdman on a bin/cue library for preparation of PSX games for retroarch on my 3DS.

    After diving into the world of soft modding, starting with my Wii, then moving onto the Wii-U, and not stopping until I had my PS2 and "New" 3DS XL all set up, I've ventured into prepping my collection of PSX games to play on my 3DS. It's been quite the journey, learning the ins and outs of each system's quirks and capabilities.

    The PSX portion of my project presented a unique challenge: managing games that span multiple .bin files and converting them into a more manageable format. I wanted a streamlined way to merge .bin files for each game into a single file and then convert these along with their corresponding .cue files into CHD format. CHD (Compressed Hunks of Data) not only saves space but is also widely supported by emulators. Additionally, for games that span across multiple discs, I wanted to generate .m3u playlists to make switching discs as seamless as possible.

    To tackle this, I wrote a PowerShell script that automates the entire process:

    1. Merging .binfiles: For games with multiple .binfiles, the script merges them into a single .binfile per game, making management easier.
    2. Converting to CHD: It then converts the .bin/.cuefiles into the CHD format, significantly reducing the file size without loss of data.
    3. Generating .m3uplaylists: For multi-disc games, it creates .m3uplaylists, allowing for easy disc switching within emulators.

    I've relied on two key tools for this process:

    • binmerge for merging .binfiles. You can find the latest release here on GitHub.
    • chdman, part of the MAME suite, for converting to CHD format. More info on chdman can be found here.

    The script assumes you have these tools installed and accessible in your system's PATH, or you can specify their paths directly in the script.

    Here's how it works:

    • The script scans a specified directory for PSX games, each in its subdirectory.
    • For games with multiple .bin files, it merges them and outputs a single .bin and updated .cuefile.
    • It converts the resulting .bin/.cue files into CHD format, saving space.
    • Finally, it generates .m3u playlists for multi-disc games, all automatically.

    This has significantly streamlined getting my PSX collection ready for play on my 3DS, and I hope it can help others looking to do the same or similar with their retro gaming setups.

    If you're interested, I'm more than happy to share the script and delve into the details of how it works or how you can customize it for your setup. Let's keep the retro gaming spirit alive and well in the most efficient way possible!

    Happy gaming!

    Has anyone made an actual good Port of Undertale on the 3DS? Like I’ve seen so many of them, but most are just not finished and don’t get updated?
