Uh, remember in the previous entry we introduced the Ophis cross-assembler? Well, it turns out there is a newer version, a 2.0 to be exact. One thing that has changed is the way we call it:
python ophis -c infile.asm
This will produce an outfile named ophis.bin which can be fed to py65mon as before. There doesn't seem to be a new version of that, at least.
In the next entry, we return to our scheduled programming.
