If you are willing to import 8080 code and run it under z88dk, you first need to convert it to Z80 mnemonics. The conversion is possible with an AWK based tool, “toz80.awk”, located in z88dk/support/8080.
The original tool is by Douglas Beattie Jr.
You need the AWK language interpreter to run this.
If the tool doesn't seem to run correctly, there might be a problem with the end-of-line marker: locate the “Record separator” comment and choose the optional behaviour.
