Once I had the Neo6502 emulator up and running on macOS. I wanted to try my hand at Mad Pascal.

I started by downloading and installing Free Pascal.

I then created a project directory called Neo6502 in my user directory. I compiled the Neo6502 emulator there using this guide that I wrote.

Finally, I followed the excellent guide from Wojciech Bociański from the Neo6502 Firmware Wiki.

I made a few changes to have everything work properly on macOS. They can be found below.

1. Clone and compile MADS

   git clone <https://github.com/tebe6502/Mad-Assembler.git>
   cd Mad-Assembler
   fpc -Mdelphi -vh -O3 mads.pas
   cd ..
   

2. Clone and compile Mad Pascal

   git clone <https://github.com/tebe6502/Mad-Pascal.git>
   cd Mad-Pascal/src
   fpc -Mdelphi -vh -O3 mp.pas
   copy mp ..
   

3. Write Hello World! program.

   cd ../../
   nano hello.pas
   

   Paste the following code into nano, then save by typing ctrl-x followed by y .

   program hello;
   begin
     Writeln('Hello neo6502!');
   end.
   

4. Use Mad Pascal to compile an intermediate assembler file

   ./Mad-Pascal/mp hello.pas -target:neo -code:5000
   

5. Use Mads to compile a binary file.

   ./Mad-Assembler/mads hello.a65 -x -i:./Mad-Pascal/base -o:hello.bin
   

6. Run the program with the emulator.

   ./neo6502-firmware/emulator/neo hello.bin@5000 run@5000
