When I try to compile the following, this is what I get:

I'm assuming this has to do with the title screen kernel because I know what all those fontchars are, they're in the titlescreen kernel, but why are they in a list of unresolved symbols if they're in there to begin with?! Anyone else have this problem? This is not the first time this has happened, either. It also spat out a binary file that's 1.99k.

I haven't checked your bB source yet, but whenever this sort of thing happens to me, it's usually because I used a variable name or line label that I forgot to add to my program-- such as "gosub mysubroutine" but I forgot to add "mysubroutine," or maybe because I changed its name without changing all the places where I refer to it.

I'll compile your source and look at the assembly listing to see what I can find out.

Okay, apparently I never installed the titlescreen kernel with bB 1.1, so after I fixed that issue (which included modifying both your program and the titlescreen.asm file to change all the slashes to backslashes, and to change the path for the titlescreen includes), I was able to compile and see the problem.

It looks like you have two problems. One is that the following line doesn't compile correctly:

 if player0x>120 then reboot : rem go to level 2, which I haven't designed yet. 

The "reboot" command seems to be broken here, because bB is trying to branch to a label named ".reboot" that doesn't exist. Oddly enough, the following line does compile:

 if e{4} then reboot

It looks like the bB compiler needs to be fixed to handle the first case correctly. That's a problem for batari to fix. In the meantime, you can work around that issue by replacing the problem line with the following code:

 if player0x<=120 then continue
 reboot : rem go to level 2, which I haven't designed yet. 
continue

But then you run into the second problem, which is that the code (including all the includes) is too large, so the ROM ends up being "reverse-indexed." It looks like you'll need to add another bank to fix that.

I fixed those problems and it's still giving me the same output. I changed all the "reboot"s to "goto title", which is where the title screen is located.

[atari2600land]

d'oh! Forgot to add "set romsize 8k." Silly me. It does work now, but I can't change the background color in the title screen to black. It ends up being blue for some reason.

Try adding the titlescreen to the beginning of a new bank.

From the docs...

Q: My colors are all weird. What caused this?

You're probably using too many screen lines. The Titlescreen Kernel can display
~85 lines using 2-line minikernels, or about ~170 lines using 1-line minikernels.

Also, sometimes dasm seems to wrongly indentify the color labels in the
minikernel image files, when code shifts in one of the assembler passes. Make
sure that the Titlescreen Kernel is the first thing in the bank to avoid this.

That didn't help at all. I tried setting pfcolors, I tried doing COLUBK=0, I tried COLUPF=0. I'm wondering if this has something to do with the fact that I'm using const player0colors=1

The include itself has to be at the top of the bank, without any of your basic code before it.

So instead of this...

  bank 2
title
 if joy0fire then goto level_1
 scorecolor=14
 CTRLPF=$03
 gosub the_title_screen_part_2
 goto title
the_title_screen_part_2
 asm
 include "titlescreen_kernel_10/titlescreen/asm/titlescreen.asm"
end
 return

...do this...

  bank 2
 asm
 include "titlescreen_kernel_10/titlescreen/asm/titlescreen.asm"
end
title
 if joy0fire then goto level_1
 scorecolor=14
 CTRLPF=$03
 gosub titledrawscreen
 goto title

[atari2600land]

It still doesn't work. What do I need to do? Define the pfcolors individually, or just put COLUBK=0 in there? I tried both.

[RevEng]

Can you zip up the titlescreen you used? The ad-hoc one I used to test worked out fine.

[atari2600land]

Here. I also put in my settings for the title screen. I wanted to use more spaces, but if I did, Stella would think it's a PAL game and flash.

I'm not sure what's going on, but I get a black titlescreen on my end. Are you using a fresh copy of the titlescreen kernel?

Here's a zip of everything from my end, including a binary.

Finally! I guess I didn't have the latest titlescreen build. Well, anyway, thanks to you and SeaGtGruff for helping me with this. Now I know what to do whenever it gives me a long, red, list of stuff the program doesn't recognize.
