DASM Mac OS X Intel

[Mikes360]

Hi Guys,

 

I am looking to do some 2600 dev on a Mac OS X Intel machine. I cannot seem to get a build of DASM that works for me. I have tried the build int the following thread which runs and seems to output a .bin file but it fails to run in Stella.

I was wondering if anyone else uses DASM on mac and has a working DASM?

I'm pretty sure that's the build of DASM I'm using on my Mac. Are you setting the output format to RAW by using -f3? The output format defaults to 1, which puts 2 additional bytes (for the origin) at the start of the file. Stella's not expecting those so it would shift everything in memory by 2 bytes. The RAW option does not include those bytes. When I compile these are the options I use:

 

dasm game.asm -f3 -sgame.sym -lgame.lst -ogame.bin

 

-s outputs a symbol list, which can be handy at times to figure out problems.

-l outputs a detailed listing, which likewise can be handy to figure out problems.

 

Here's the manual for DASM:

Ahh yes now the binary works perfectly! Thanks for pointing out my obvious mistake.
