hi, i'm taking the tutorial at http://www.neshq.com/6502program/nesprogram.txt by joker21.
in the section named "adding CHR-ROM" you're told how to code chr.rom but not how to actually create it.
am i missing something? is he telling me to use another doc?

Code: Select all


C:\nesasm\sprites>nesasm babyrom.asm
NES Assembler (v2.51)

pass 1
#[1]   babyrom.asm
   34  02:0000                    .incbin "test.chr"      ;gotta be 8192 long
       Can not open file!
# 1 error(s)

I'm not sure what you mean exactly. That error looks like you don't have a file by the name of "test.chr". If you don't have a file named that, you have to create one in YY-CHR or any tile editor that supports NES graphics format. And it has to be 8k. I don't know if that's what you're wondering about.
