Will DASM do this for me?

[+grafixbmp]

I need to place 2 tables of bytes (graphical data) in rom. However, i need one loaded in even addresses and the other in odd addresses. I would like to avoid manually interlacing my graphical data as well as color palettes. People keep saying let DASM do it for you so was wondering if it was up to the task.

I don't know of a way to do this via DASM. I'd probably use an external script to generate my data for this case. You might ask in the DASM club and see if more experienced users have a suggestion:

I don't think DASM can do much help here.

 

Maybe try this:

	.byte %11111111, %00000000
	.byte %11111111, %00000000
	.byte %11111111, %00000000
	...

With 1st graphics as first byte and 2nd graphics as second byte.

That's what I did for the RPG Bus Stuffing demo, the tiles are defined with colors interlaced with graphics:

An underline is better contrast than a zero, and a valid identifier character in sane programming languages, so I like to use an include file full of this:

 

#define ___X____    0x10
#define ___X___X    0x11
#define ___X__X_    0x12
#define ___X__XX    0x13
#define ___X_X__    0x14
#define ___X_X_X    0x15
#define ___X_XX_    0x16
#define ___X_XXX    0x17

 

or for assembly:

 

X_X_____    EQU    A0H
X_X____X    EQU    A1H
X_X___X_    EQU    A2H
X_X___XX    EQU    A3H
X_X__X__    EQU    A4H
X_X__X_X    EQU    A5H
X_X__XX_    EQU    A6H
X_X__XXX    EQU    A7H

 

I also have a 4-bit set, and similar ones for the reverse bit-endian:

 

___O__O_    EQU    48H
O__O__O_    EQU    49H
_O_O__O_    EQU    4AH
OO_O__O_    EQU    4BH
__OO__O_    EQU    4CH
O_OO__O_    EQU    4DH
_OOO__O_    EQU    4EH
OOOO__O_    EQU    4FH

 

I put commands to generate these lines to the interactive disassembler I wrote a few months ago.

xobits.h xobits.s

I did that when I wrote Medieval Mayhem. It worked well for coding, but not so well for debugging as Stella would often show those instead of a more relevant label:

 

I now let my editor colorize binary for me.

At least this makes the manual method a little easier. Just had hoped there could be an ORG/RORG EVEN/ODD feature

If the editor you're using has a "block" mode (i.e. a way to select, copy and paste a rectangular region of text), then it's very easy to move the existing non-interlaced tables side by side like in the examples above.
