No idea about the ErrDisp. Please check your SD just to be sure this isn't the cause.

The "Game Pak Error" message is part of a pretty extreme and ridiculous copy protection and anti-emulation. The relevant resource for this is:
http://mgba.io/2014/12/28/classic-nes/

There are some cracks/fixes/patches out there for the Classic NES series (and the later entries in the Japanese series as well). I neither have a link nor do I know if those may be linked on GBAtemp and never tested them myself.

If those cracks are just patches that replace small parts of the ROM without containing the actual game, then linking should be okay. (The problem with linking cracks for e.g. Windows games is that they are often prepatched .exe files that are the complete game which obviously means copyright infringement. I guess this is why the forum rules just state "No cracks!")


It is worth noting that mGBA emulates those games correctly without any patches. On the new 2|3DS series the emulator is worth a try.

Good luck and have fun!

    If you're designing from the ground up you'll need php to store registration information into mysql databases

  • felix.200 @ felix.200:
    you don't need php you just need some backend if you need registrations

    If you use a service it's still technically not your coding unless it's open source

    The backend code can be written in a lot of languages

    " that's just styling" fair but styling is important

  • kenenthk @ kenenthk:
    Yeah but you still need to know more then css html and js

  • felix.200 @ felix.200:
    it certainly is

    Styling is not important lol

    but css is for designers or full stack devs

    If you have enough information stored users could care less if it's black and white

    yeah but i would prefer websites to not look like dogshit

  • felix.200 @ felix.200:
    Why would you need more than js, html and css for a basic website? You might need sql for your database but thats about it

  • kenenthk @ kenenthk:
    If you want to truly call it your work that's why lol

  • Julie_Pilgrim @ Julie_Pilgrim:
    actually that makes me think what's the line between "tolerably bad" and "this is so dogshit i won't even think of using it"

    what? lol

    If I write all my js css and html why would the work not be mine?

    A basic site sure doesn't need it but if you want a community it's important

    But still style isn't everything when it comes to websites
