a few problems

[vixo]

when I try and compile anything with nesasm through DOS, it just crashes and gives this message -



- although I can get it to work if I drag and drop the code file onto nesasm. I'm trying to get the code from joker21's guide to work -

Code: Select all

        .inesprg    1
        .ineschr    1
        .inesmir    1
        .inesmap    0

	.org $8000
	.bank 0

Start:


	;this sets up the PPU
	lda #%00001000     
	sta $2000          
	lda #%00011110 
	sta $2001

        lda #$3F        ;set ppu to start of palette
        sta $2006       
        lda #$00        
        sta $2006 
	ldx #$00

loadpal:
	lda titlepal, x  ;loads a 32 byte palette
	sta $2007
	inx
	cpx #$20      ;gotta be one extra b/c of inx
	bne loadpal

Loop:
	jmp Loop


titlepal: .incbin "test.pal"	;palette data


    	.bank 1
	.org	$FFFA
	.dw		0 ;(NMI_Routine)
	.dw		Start ;(Reset_Routine)
	.dw		0 ;(IRQ_Routine)

    .bank 2
    .org    $0000
    .incbin "test.chr"  ;gotta be 8192 bytes long

The guide states that I HAVE to have a 4kb test.chr, but I can't figure out how to get anything less than an 8kb CHR file (I am using YY-CHR)

If I try dragging and dropping onto nesasm with this code, nothing happens. But if I erase both .incbin lines from the code, it assembles.

Can anyone help me to a) get nesasm to work through DOS
b) get the .incbin command to work
c) get a 4kb CHR file

- I would be very grateful

See if you have the newest nesasm.exe (v2.51).. I remember having trouble with an older version. I don't know what else the problem could be.

c) get a 4kb CHR file

Get a hex editor. It's like a swiss army knife of binary file hacking. Frhed is the one I use: http://www.kibria.de/frhed.html. Then just cut it in half at 4096 (or 0x1000).

Yeah, I had that problem with an older version as well.

I've got v2.51 now, but it still crashes when I use it through DOS.

any other ideas?

I had written a small prog called makebin to make blank binary files for use in NES Dev.

You can make 4kb files with that easily.
