I want to see the source code for this. I opened sourced my iOS remake[1] but I would love to see what this code looks like.

It's probably mostly written in assembly. (Or Forth, if you are extra lucky.)

stevoski• 12 years ago

Dammit, the C64 always gets the good games first. I hope they make a port for my Amstrad CPC.

mattl5• 12 years ago

Don't worry, Ocean is working on a crappy Speccy port right now.

Syssiphus• 12 years ago

This made my day :D

pjmlp• 12 years ago

Actually for those living in Portugal, Spain and UK we get 128/48K games first.

I seldom see any C64 around here, besides magazines.

Looking forward to see the game on the demo tape on the next month's Crash.

ck2• 12 years ago

I am starting to understand the "because we can" mentality.

If my estimations are right, we should see a CSS-only version that doesn't use any javascript next month.

ps. in case someone needs css-only ideas http://liveweave.com/wC3DB2

How about the version written in BrainFuck?

sirsar• 12 years ago

Main problem is graphics; there's no specification about that in the language, so you'd need to be writing to video memory, or do something funky with the print statements

angersock• 12 years ago

Excellent!

Soon, you'll be ready for NodeJS.

onion2k• 12 years ago

I made an JS+canvas version the other day http://codepen.io/onion2k/pen/ifroz …so I could do one that fits in a 'favicon'… http://ooer.com/flappicon/

(probably only works in Chrome)

evan_• 12 years ago

That's great, you should enter that in JS1k: http://js1k.com/2014-dragons/demos

anon4• 12 years ago

here's a quick and dirty fork to make it restart when you click

I'm surprised there isn't a version built inside minecraft yet.

timpark• 12 years ago

There is.

userbinator• 12 years ago

I was going to do one for the TI-83, but then found out someone else had done it already ( http://www.cemetech.net/programs/index.php?mode=file&id=1039 )... it's getting hard to find a platform that hasn't got Flappy Birds ported to it already!

seba_dos1• 12 years ago

Kinda similar in its spirit - here's my curses based adaptation for any vt100-compatible terminal: https://github.com/dos1/flasciibird

diydsp2• 12 years ago

Delicious, runs great under cygwin.

Joeman• 12 years ago

My C64 is a bit rusty. But shouldn't that load command end with ",8,1"?

mattl5• 12 years ago

It's not loading from disk, right?

the_sos6• 12 years ago

It's loading from an SD FDD emulator interface, but I have cut the loading, since it was as long as from an actual disk.

evandeaubl• 12 years ago

I'm probably equally rusty, but I believe ",8,1" loaded programs written in machine language, and ",8" was for BASIC programs (at least that's what I recall doing). So it looks like the port was written in BASIC.

fogleman• 12 years ago

Looks like you might be right...

,0 The program will be loaded to the start of BASIC memory (2049/$0801)

,1 The program will be loaded absolute, i.e. to its stored location defined by the first two bytes in the binary file. Needed for machine language programs.

http://www.c64-wiki.com/index.php/LOAD

a1k0n• 12 years ago

Just because it doesn't have the ,1 doesn't mean it's written in BASIC; it could still be written in machine language with a BASIC stub that executes the actual code (which is loaded into the BASIC memory area but isn't necessarily BASIC) when you type RUN.

iclelland• 12 years ago

The first argument, ",8" caused the load to come from the attached disk drive, rather than the default cassette interface. The second argument, as explained by others, was to load binary files into their defined locations.

So you could also load binary programs from cassette with a LOAD "*",1,1

the_sos6• 12 years ago

I forgot ,1 but it still worked, sorry for the confusion!

feelstupid• 12 years ago

Using 'ported' assumes that you gained access to the original source code for Flappy Bird, rather than just recreating Flappy Bird on C64.

robert_tweed• 12 years ago

Not necessarily. The word just means [trans]port to another platform. It's only relatively recently that writing automatically portable code has been possible, and even then there's usually some modification involved, otherwise we'd just call it "recompiling".

It has been used this way in relation to games for years. Game ports of the 80s and 90s very often involved complete rewrites from the arcade version, sometimes without access to even the original graphics.

vidarh3• 12 years ago

I remember reading accounts of ports where the porters were not even given a spec of any sort, but were lent an arcade cabinet of the original and had to essentially test there way through everything to figure out what to implement.

the_sos6• 12 years ago

I wanted to emphasise trying to stay as close as possible to the original as possible, while still being a C64 game. I didn't have access to FB source, so it's just reverse engineered. It's still in need of tweaks and fixes tho (I spent 2 days on it).

scragg• 12 years ago

Can we stop voting up the flappy bird stuff.

gabriel34• 12 years ago

But then our bird would fall down or hit a pipe or something

quarterto• 12 years ago

waaaa waaa the consensus isn't what I want so can everyone just change their preferences

SwellJoe• 12 years ago

I upvote C64 and 8 bit stuff, because I find it really interesting and fun to read about. Even if there's a flappy bird on it, I still upvote it.

null_ptr• 12 years ago

Yes, more JS MVC stuff please, if a link doesn't have at least 2 of "web", "framework", or "node" in the title it's unfit for consumption.

hibbelig• 12 years ago

No.

loser777• 12 years ago

I'm saddened that there's no kickass SID soundtrack for the game. That would have been a great way to show off the C64's technical advantages over the iPhone ;)

bliti• 12 years ago

I think it makes more more sense as a C64 game than anything else. It just fits the era and machine so well. Made me think back to the good old days where I would spend all day playing games on my C64.

vidarh3• 12 years ago

The earliest game I remember where at least one of the levels used the same game logic was Dragonsden from 1983.... But there were at least one more that I can't remember the name of...

zephyrfalcon• 12 years ago

Here's a video of another version (although I'm not sure if it's available for download (yet)):

Happy Flappy ~ http://vimeo.com/87434521

jggonz2• 12 years ago

Beautiful work. In only 64K of RAM and probably more fun than the phone version! :) Makes me so envious of people that actually have a working C64 to try this on!

cgh4• 12 years ago

Actually only ~38K of RAM plus the 4K section starting at address 49152.

diydsp2• 12 years ago

Lest people get the impression the C64 does not have 64K of RAM, I am here to assert that it does in fact have a full 64K of RAM.

mappum• 12 years ago

The creator of this is Sos, the developer of the game "McPixel". He is well known in the Ludum Dare community.

syntaxfree• 12 years ago

This is... beautiful.

nkuttler2• 12 years ago

I still boot into x64 from time to time to play old games. Games that are much more playable than flappy bird. Sometimes I also like to listen to sid music while working.

dysoco• 12 years ago

Sos awesome as always! Keep on going.

wozname• 12 years ago

Obligatory zx81 version, video: http://www.frequency.com/video/just-released-for-zx81-is-qua... The official homepage: http://www.bobs-stuff.co.uk/quack.html

This C64 version is pretty awesome though!

JTenerife• 12 years ago

Oh my ... hackernews, where are you going to?

the_sos6• 12 years ago

Hi! I made this! Thanks for mentioning it here! Let me know if you have any questions!

BHSPitMonkey• 12 years ago

Is the source code available somewhere?

the_sos6• 12 years ago

Well, it was written in assembly anyways, so you can decompile it, but there are many macros I used, so it might be hard to read (for example scrolling is done without a loop, just 1000 separate instructions). There's so much spaghetti in there. I'll probably release that once I have some time to clean up a bit!

jameshk• 12 years ago

What is with this Flappy Bird obsession? I stayed away from it.

Although a beginner could have some fun coding a clone.

erickhill• 12 years ago

Probably something to do with the fact that the game was (allegedly) pulling in ~$50k/day at the top of the charts in iTunes with very little focus on monetization.

That was combined with an exceedingly simply UX anyone could understand.

And then the developer, to many people's shock, decided to pull the game. He said he didn't want the attention.

Like all popular games - especially the simple ones - there have indeed been a ton of clones pouring into the store.

DigitalSea• 12 years ago

Can't wait to see someone ironically port this over to SNES.

ThomPete• 12 years ago

ZX81 version https://lh5.googleusercontent.com/-0disyFsqTyE/Uv_yxfBfPsI/A...

donniezazen• 12 years ago

Is Flappy Bird really so much fun? I quickly lost interest after losing a few times.

supercoder• 12 years ago

That's why people write implementations of it instead of playing it.
