Suggestion: user controlled bank size. about 6502.net

[informedcitizenry]

Okay thanks. Yes, currently the output buffer is static 64KiB byte array, so this would require a rework, which I have been thinking about anyway, since an 65816 can conceivably support 16MiB program. I'll mark this as an enhancement to track and hopefully can include this in a couple releases.

The .bank directive is currently only available for 65816 assembly to support long addressing (>64Kb). If we had a way to do what you are asking, do you have sample code demonstrating how it might be used?

[JettMonstersGoBoom]

for example i'd suggest only allowing one size specification like
.banksize=$4000
.bank 0
.relocate $8000
some code
set second code bank to 2 ( depends on hardware )
NES for example has two pagable rom banks for code individually selectable.
.endbank
.bank 1
.relocate $c000
more code
.endbank
.bank 2
.relocate $c000
more code
.endbank
.bank 3
.relocate $c000
more code
.endbank
.bank 4
.binclude "chars.chr"
.endbank
.bank 5
.binclude "sprites.chr"
.endbank

expected result is a file $18000 bytes

The latest release should address what you are wanting to do (if I understand correctly the intent). You will need to pass the --long-addressing option. The sample code you wrote above would be like this:

		* = $8000

bank0     lda #$00
		tax
		jsr $c000
		// more code
		.fill $4000 - (* - bank0)

bank1      nop
		// more code
		.fill $4000 - (* - bank1), 0

bank2      nop
		// more code
		.fill $4000 - (* - bank2), 0

bank3      nop
		// more code
		.fill $4000 - (* - bank3), 0

               // etc....

works for me . thanks
