Flagon Bird

Hi.
Flagon Bird is a game I've been working on in my spare time in order to learn how to program the Dragon using assembly language.
I noticed many of the older computers and consoles had Flappy Bird clones so I thought I'd do a demake for the Dragon and CoCo.
It's missing sound and a bit of polish here and there but I thought it was far enough along to be worth releasing.
You can use any key on the keyboard or joystick button, (I've only been able to test a joystick via XRoar).
Flagon runs in a frame, even at 60Hz on the CoCo, but means I need to perform more optimisation to fix the outstanding graphical issues.
Anyway, hope you enjoy it.
Bosco.

Great job Bosco! Very nice graphics and good color combinations!
This is going to become a number one hit!
My all-time best score is 2 though -- I can't fly this puppy straight...
I'll test it on a real Dragon tomorrow and report.
EDIT:
Just got past #3!!!
I'm using a long-stroke keyboard here and I think that's something to consider.

Thanks!
I've been feeling nervous about posting it.
I get high scores, (when I'm in the zone), and low scores too. Hope I haven't made it too frustrating? Or is that the point? LOL
Testing on my Dragon today I was pleased with how smooth the screen update looks. Under PC emulation on a 60Hz display you get a very subtle stutter (when emulating a 50Hz machine).
I've also tried it on my budget tablet using XRoar for Android. Runs a bit slow but still playable.

That is brilliant! And the most annoying thing in the world ever, of course
2 is my high score...
Edit: 5!

Really nice! It looks great and has the 'one more go' factor. Just blown my lunch break playing it

An excellent work!
Difficult as hell (I haven't got beyond 4
), but awesome nonetheless!
I really love how you managed to nail the graphics and the scroll.
Maybe some music on the title screen and some effects would have been nice, but does not make the game worse in any way.
Keep up the good work! The Dragon is only warming...

By the way, looking at the game's size, would it be possible to have a rom version?
That would be ultra-awesome, hehe!

Thanks for the great comments!

I cobbled together some last minute music and effects but wasn't happy with them. Hopefully should be back for v1.1. Does anyone have any useful links for coding 6-bit sound?
would it be possible to have a rom version?
Yeah, sure. You'll need to tell me how though.

I tried creating a rom file with a small loader to copy the game code to the right location and jumping to it, but it seems I need to initialize tha machine first.
Code: Select all
org 49152
ldd #3766
ldx #49178
ldy #16384
loop
pshs d
ldd ,x+
std ,y+
puls d
subd #1
bne loop
jmp 16384
INCLUDEBIN ./flagon.bin
Maybe @Zephyr could help us a bit here.
