This is awesome, but is it... legal?

  Yeah, that title is just begging for a takedown

    They are hosting copyrighted game ROMs directly on github pages, lol

      It's pretty terrible. It's not hard to require that the user select a ROM from his or her local machine. Web browsers go to the trouble of supporting blob URLs for a reason.

        http://taisel.github.io/IodineGBA/ http://taisel.github.io/IodineGBA/ is one where you load your own in. You need the BIOS ROM in addition to the game ROM, as it's all LLE emulation, no BIOS SWI HLE'ing.

        I don't think anyone is arguing that the capability is missing, it's more that https://github.com/playnintendo/gba/tree/gh-pages/Binaries https://github.com/playnintendo/gba/tree/gh-pages/Binaries is an egregious violation of so many things

        Also lol, Firefox is running this way faster than Google Chrome.

I can't find the correct control keys, any help? edit: left arrow right arrow w = start x = action (jump for instance) This is fucking amazing!

  Seems to be different for different games. In Bubble Bobble it's left, right and j for jump.
weinzierl 11y ago
This is awesome. The music sounds horribly off key. I just checked out a youtube video of Bubble Bobble to be sure it's not my ears or memory - no the sound is off. Is the sound really broken or is it just on my machine (Mac Book)?
- red_rojo 11y ago
  It means something is lagging the emulator. It slows itself down to partial speed when it's not allowed to run fullspeed. Edit: Firefox runs this faster than Chrome by a considerable margin, just FYI.

    Firefox user on OS X reporting in. Super Mario Advance 4 caused a kernel panic within 60 seconds and force-rebooted my laptop. I was resizing the window while the emulation was taking place which may have been a factor.
    - cmdrfred 11y ago
      Can anyone confirm? I don't have a mac but wouldn't JavaScript that can cause a kernel panic be defined as an exploit? (You might be able to resize it with an iframe)

This is pretty amazing! And it works so smooth!
aelmgren 11y ago
Amazing. Can anyone give a brief description of how this works? It looks like it's already down too. www.letsplaysnes.com/ also does the same thing it looks like.
borplk 11y ago
Cool! Couldn't find any way to skip the long demos on some of the games :/
- aelmgren 11y ago
  or save... looks like you can't do that either

Grant Galitz, why do you keep submitting this on a new repository after Nintendo takes your old repository down (see https://github.com/github/dmca/blob/master/2015-07-06-nintendo.md https://github.com/github/dmca/blob/master/2015-07-06-ninten...)? This is the 4th time you've submitted this to Hacker News, each time with brand new Hacker News and GitHub accounts. (The OP created his latest Hacker News account 4 hours ago at the time of this comment) It's illegal, so no matter how many times you keep re-uploading it to GitHub it will eventually be taken down again and again. The more you defy Nintendo's DMCA takedown requests, the more likely Nintendo will notice and possibly try to track you down and sue you in person. I understand that you want to show off your legal work (https://github.com/taisel/IodineGBA https://github.com/taisel/IodineGBA), but the only way to show it off is to require users to provide their own ROMs. More proof that this is the same poster: https://github.com/playnintendo/gba/commit/e429bacd4d5fef715160c25e3337f726a711555b https://github.com/playnintendo/gba/commit/e429bacd4d5fef715... He forgot to change "jsemu" to "playnintendo" before re-uploading his repository to GitHub.

  The DMCA from Nintendo to "jsemu": https://github.com/github/dmca/blob/master/2015-07-06-nintendo.md https://github.com/github/dmca/blob/master/2015-07-06-ninten... I guess he just doesn't read the DMCA sent to GitHub or something? If you're going to write an emulator, fine. Distribute copyrighted games? Don't do it... They keep taking you down over it. I agree with Sephr.

  Why do users keep voting this submission up? It has 66 points currently.

    People love games and emulators, and not everyone has seen this before, or recognizes it if they have. (I didn't.)

At the time I am writing this (6 hours after submission), I get a "site not found" error from GitHub. Has this been taken down? EDIT: well, the repo is here: https://github.com/walsh/gba https://github.com/walsh/gba
