Holy Shit! Mario 64 works on Java

[kapta]

As so happens someone somewhere wrote an n64 emulator known as Project64, then dooglamoo ported it to java. I thought it'd be an interesting experiment to see if it could be run in a browser. So i've spent some time porting it to LWJGL and making it work as an applet.

Which gives you Super Mario 64 in your browser, complete with ingame saving so you can come back to it later and continue where you left off. Pretty impressive huh?



You can play here

note - its still pretty experimental and sound is borked, also reports of flickering on ATI cards (crappy drivers?).

p.s. sorry for the title it was a reference to the Holy shit! They made the flash version of DOOM!! post

You can add to that a report from me of flickering on an nVidia 8600M GT in Vista, driver 190.89

How do they do the dynarec that the original does?
(whatever - to - 86x assembly)

[CommanderKeith]

That is amazing! Great work with the port to LWJGL.

I saw some pretty serious flicker as well, it seemed like there were 2 versions of the game running - one that ran fine and another that would display white frames or old previousluy shown frames. As soon as you see it happening you'll probably know what the reason is straight away.

ah could explain the flickering will have a look at that, thx for the observation.

[kapta]

@CommanderKeith I've added a small fix, it might fix the flickering, could you try again? thanks

Crashing Safari and Firefox on OS X:

eww that looks like a nasty error.

[CommanderKeith]

Nice, that did the trick! Graphics are 100% smooth.

Wish I had those secret magic codes to fix my bugs so quickly 

[JL235]

Graphics don't flicker for me, it all runs fine. However the sound is a complete mess. That's where the flickering occures for me.

Same thing here. Great job kapta! That's so cool!

[i30817]

That fixed the flickering for me too. 

So it was actually two apps?

And you might want to tell him you've ported his software to use LWJGL if he doesn't already know.

[Demonpants]

Very very cool. Well done. Works better than the best Mac OS X N64 emulator.

[lhkbob]

Worked without nasty exceptions on Mac OS X on Safari for me.  Way to go!

[xinaesthetic]

Well done, the flickering seems to be fixed now, but I'm still having problems with the sound as well (didn't mention that before).

[h3ckboy]

NICE!

that is amazing.

did yuo port the emulator or the game?

by that I mean, how much effort would it take you to change it to another game?

[xinaesthetic]

I presume the emulator was ported.

Incidentally, I tried dooglamoo; it didn't seem to load Mario by default so I loaded a Zelda rom I had lying around, and it had similar problems with audio.

[gouessej]

It works fine, it is a bit slow on my machine but quite playable. I get this when I leave the game:

Unfortunately can't do much about the sound, It uses the original JavaSound Implementation which is a pretty poorly implemented. It'd probably run alot smoother using OpenAL but currently the sound code is a mess and i don't have the time or experience with OpenAL to port that part. However do note its only dooglamoo's first attempt at the sound plugin so may improve in the future.

I presume the emulator was ported.

you presume correctly.

how much effort would it take you to change it to another game?

very little effort.

I get this when I leave the game:

Ah, doesn't look too serious, but thats one long exception paste

[TheAnalogKid]

Yes, it seems to be a bit slow or the frame rate a bit low. Can I display the fps? Doesn't seem to be a CPU issue since mine was used between 50% and 60%.

Othen then that, I hope Nintendo nevers learns about that, especially with the virtual console on wii.

[zammbi]

Works fine here.
I also have the sounds problem.

Not sure if its the game itself, or that the game isn't made for a keyboard but I found its controls annoying to play heh.

Well, he can always provide access to the emulator with no legal issues, the only problem is if he continues to keep a direct link to Mario 64. Otherwise people can go download the ROM from one of a bagillion sites and then just load it in manually.

[DzzD]

wow

work very well ( seems a little slow ) but not that much very playable with a nice experience ( CPU :  80% on one and 40% on the other ).

I got a sound issue : like if I was underwater

but wow really impressive for an emulator

[JL235]

I forgot to say before, I was very impressed by this. It really goes to show what is possible with Java.

[DoubleBarrel]

Wow I love this   
Is this only a demo of the game? I can t progress to anywhere in the game in terms of storyline ...
With regards to technicalities I have to repeat what have been already said ... cool gameplay (most of) but poor sound.
Thanks for your work man 

[steveyO]

Holy f'in Shit..  Thats impressive to say the least!!
No flicker,, just sound probs as mentioned by others..

[CyanPrime]

Wow! This is fantastic!
I put it on my blog for you, too ^_^

Might be a Java version thing or a graphics card issue, then, I'll look into it a little later today.

[ChrisM]

Very impressive, posted about it on my blog.  I wish the guys who did the PS1 emulator back in JavaOne 2006 would release their code as their emulator was smoking hot.  I believe they were running 3 PS1 games at 30FPS at the same time on their laptop.  Crazy!

[TheAnalogKid]

Too bad the sound is crappy. But what's so great is that it seems to run better than with Project64, apart the sound. If I remember correctly there was flickering issues on Project64.

[i30817]

Its probably a good idea to ditch the game loading/download now and just popup a filechooser for people to play their (legally dumped of course) games.

Would make startup faster even right?
