Flappy Jack. I wrote most of this last year, and never finished it. I've been touching up a few things, adding a few new features. All that's left is to redo the music and do some play testing.
You have to catch the pancakes as they fall from the top of the screen. As your stack gets higher, it's harder to catch them. As the levels progress, it gets faster and faster.

Then I was getting a weird bug with Noise channel sound effects, that I've managed to fix, but somehow related to the fact that famitone only once writes to $400f, and assumes always a constant note to be playing (sometimes with a volume of zero). Somehow my sound effect (or something) turned off the constant note, after which no noise channel played. Took me an hour to debug and solve. =(
Anyway, it's 99% done, just need to fine tune a few things.
I thought I would share a tiny bit of code. To play the same famitracker/famitone2 song at different speeds...
Code: Select all
lda level cmp #$10 bcs + lda #9 sta FT_SONG_SPEED ; levels 1-9 slow music jmp Game_Music + cmp #$20 bcs + lda #8 sta FT_SONG_SPEED ; levels 11-19 medium music jmp Game_Music + lda #7 sta FT_SONG_SPEED ; levels 20+ fast music Game_Music: jsr FamiToneUpdate ;MusicEngine
See the dithering on the letters? Also the pancakes (color 17) look like nearly the same color as the sign (color 16).
Compare to a random other game, and it has no dithering issues on the same TV.
No yellow bird? No yellow mole?
That's a very good explanation. Did you know that using a non-round number in an explanation makes it 26% more believable. I just made that number up, but I'm betting that you researched your answer. Maybe I should try a non-slanted sign.Any color boundary with diagonal lines of slope 2 (26 degrees clockwise of vertical) has a potential for such artifacts on NTSC NES or Super NES because of how pixels line up with the color subcarrier. Unfortunately, this is the common amount of slant for cursive.
For legal reasons, I'm claiming that any similarly to popular games with similar names are purely coincidental.No yellow bird? No yellow mole?

Mostly L + R to move
Holding A or B will boost your speed
Start to Pause
The game is considered 'won' if you score above 100,000 pts and see the 'good' ending.
You can cheat and press A and B and Start at the Title Screen to see the 'good' ending.
It is technically possible to reach level 99, but not very likely.
Let me know if you think it is much too hard or much too easy. Thanks.
