7800AsmDevKit

7800AsmDevKit Overview

7800AsmDevKit is a collection of tools required for developing games for the 7800 in assembly code. It contains the following components:

release info: 7800header updates - added ability to flag multi-region, mega7800 controls.

1. Unzip the 7800DevKit package and move the new directory to a convenient location, renaming the directory if you like.

2. Run the installation script for your Operating System and follow the on screen instructions:

Linux or OS X: open a terminal, "cd" to the 7800AsmDevKit directory, and type "./install_ux.sh"

Windows: open a CMD window, "cd" to the 7800AsmDevKit directory, and type "install_win.bat"

If you move or upgrade, simply re-run the script again to register the new location, and re-open any command windows.

To assemble a binary ROM image from 7800 source code with dasm, open a terminal/CMD window and type:

7800asm sourcefile.asm

This will also run the 7800sign utility to cryptographically sign the resulting binary for the 7800.

You are, of course, welcome to run dasm and 7800sign manually if you wish.

The samples/simple directory contains simple.asm 7800 source code that you may examine and test with.

To create an A78 file for emulators, simply type the following, substituting your own filename for BINFILENAME:

7800header BINFILENAME

To modify an existing A78 file, simply type the following, substituting your own filename for A78FILENAME:

7800header A78FILENAME
