Atomic Flappy Bird

Postby oss003 » Thu Jul 31, 2014 7:39 pm

Hi guys,

I want to share the preview of a new game I'm writing, Atomic Flappy Bird.
flagon.png

Steve Bamford has written Flagon Bird, a Flappy Bird port for the Dragon, a video can be found at:

https://www.youtube.com/watch?v=HiTOYig4-bk

This video and the story from Tricky about his Phoenix game was my inspiration to write Atomic Flappy Bird from scratch because it looked very good. The Dragon and Atom both have a 6847 as video processor so the graphics can be exactly the same. My guess is that the 6809 processor in the Dragon is faster with 16-bit data handling than the 6502 in the Atom so I hope to complete the game with reasonable speed.

My findings can be found at the Retrosoftware site:

Back from holidays? :lol:

It really looks great. Nice work how you keep a solid background while other object move from right to left =D> The 6809 is indeed faster on 16 bits data as it has a 2 8-bit accumulators (A and B) which combine to a 16-bit accumulator D. Also the index registers X and Y are 16 bit. So yes, on 16 bit calculations it will be a bit faster than the 6502.

As you know there are several projects in Atom News for installing a 6809 in the Atom....

Flappy Bird might be the very first rom for the Atom 6809 (second) processor. There are several hardware solutions for a 6809 but there isn't any usable software. Not even a port of the Flex OS (at least, not that I'm aware of)

Bas Kasteel and Jan Swinkels did some testing with a 6809 in an Atom, maybe one of them still has some hard- or software.

There is an open source port of OS-9 (NitrOS-9) that runs on the Tandy Colour Computer & the Dragon 64, shouldn't be too hard to port that.

Cheers

Phill.

Bas Kasteel mentioned AtomFlex in Atom News (http://acornatom.nl/atom_nieuws/1987/nr5/19875030.htm) but afaik there wasn't any follow up. Even Jan Swinkels didn't manage to get a copy of flex.

I found out that I didn't publish my own 6809 project in Atom News. I'll try to find some docs I made and put them online.

Back to topic: how's Flappy?


Edit: I just started a new topic about 6809 at viewtopic.php?f=44&t=8518

Hi guys,

Time for another update:

For phase 4 have a look at: http://www.retrosoftware.co.uk/forum/vi ... 6747#p6747

There's also an explanation about how the pipe scrolling routine works.

Really looks great.

I never heared about Flappy Bird in the past but just after you started this topic I saw the name of the game twice in the dutch Linux Magazine :D Must be a popular game....

Brilliant Kees! =D>

I don't know how you manage to do it... this would be impressive on a BBC, but on an Atom it is amazing.

Hi guys,

I did make a SID version of Atomic Flappy Bird and showed this in Halifax.

A video can be found at: https://www.youtube.com/watch?v=gLuj133FA8U

Today I discovered that you can also use the copy key to move Flappy. This works better for me ... I reached a score of 7, my personal record \:D/
