Working with multiple banks

I recently switched from XKAS to WLADX (thanks for the tip Revenant!). I am having trouble with the .BANK directive. I have a bunch of stuff in the first bank using
. However when I try to put stuff in the second bank with
nothing is put there in assembly i.e. from $10000 to the end of file is completely empty. I have searched all over but can't find a single WLA asm file online that uses multiple banks; I'm starting to think I am the only person suffering with this problem.
I have provided the asm file (scrollsnes.asm). If anyone could look at it and provide insight I would be very grateful.

Here's the first
example that comes to mind.

Your mistake is using
.ASM and
.ENDASM in the wrong fashion. Whatever you put after
.ENDASM will be completely ignored by WLA, just as if it was commented out. (The
.ASM directive, on the other hand, tells WLA to continue assembling your code/directives. IOW,
.ENDASM equals
/*, and
.ASM equals
*/).
Also, your
.DB and
.INCBIN directives need dots.
This is how your file (scrollsnes.asm) should look like so WLA assembles it just fine:
Code: Select all

Sorry for the late reply. I really appreciate you taking the time to look at it. I'm sorry it wasn't something more taxing. I just had it in my mind that "asm goes in asm directive". Anyway, it works now so thanks again.
