I found a problem with the TI-84 conversion, however low and behold I have only needed to do some bug fixing. The new file should work just fine.
https://github.com/DaSovietPotato/Drugwars-TI-84

Is this version based on the IBM Basic source code from the original 1984 game or has the game functionality been determined by playing/testing? I'm trying to port the original DOS game to a different platform (Sega Master System) and want it to be authentic as possible but this will require disassembling the DOS executable which (I think) would have been generated using the IBM Basic compiler and so probably has a lot of IBM Basic environment code in there that I don't understand.

Do keep us informed @gammalogic. I think it is based on the original but thats just my guess as I could not find the original source aside from reverse engineering it.

Maybe it is out there somewhere in the wild though.

I found many sites with the code to older versions starting with the dope wars from 2000 or so. but they are different and improved

Good luck

Hey y'all. This gist shows how to program the game on a TI-82 graphing calculator. I believe the TI game is based on the IBM game, but you wouldn't be able to compile this for other platforms. You could use it to give you an idea of the game's rules and logic though. I found this somewhere on the Internet many years ago and cleaned up some of the character formatting to make it more readable, but that's about the extent of my knowledge.

Thanks for that Matt. I am pretty sure you are right about it being based on the original code as well just based off gameplay.

I still have this on my calculator and my phone and while I don't really play it I enjoy quite thoroughly having it, so again, ty.

@gammalogic I think your best bet is to just go line by line (having fun with the gotos/labels) and port the code to whatever language you want. You are going to want to know BASIC but its actually very easy and basic in many ways just look for a TI-83 manual and check what each line of code does and learn as you go and you will be done by the end of the day.

For example just using a search engine for

"ti-83 manual goto meaning"

I get

"The Goto command is used together with the Lbl command to jump (or branch) to another place in a program. When the calculator executes a Goto command, ."

Simple enough! Good luck!

Thank you @mattmanning and @ileathan for your comments. The TI-82 code is a great starting point even if it isn't 100% accurate to the original code (which it might be). I have done some C and SDL programming so I would like to re-implement the game in that first, then look at the Z80 version next. I had also considered running the original Drug Wars in a DOS emulator with debugging enabled, so that I could check to see what values are in the registers/memory when the game is running. This game seems perfect for a retro console (i.e. Master System, Game Gear or NES) hence my idea to try and port it to the Z80. I do have some ideas for extending the game but the original version is priority with a "2.0" version as a bonus i.e. let players choose which one they want. This isn't necessarily vaporware as I got as far as putting together a basic C/SDL tech demo about two years ago running at NES screen resolution with memory mapped video emulation to display the stash and trench coat totals in nice bordered windows and let you change amount of drugs and current location. There was also an option to change the location from New York to Los Angeles and have different types of drugs for sale e.g. crystal, all fairly obvious but with different colour schemes and graphics to keep things interesting.

Just as a point of interest, John Dell said that he was inspired to create Drug Wars after playing the TRS-80 game "Taipan". The author of that game also co-authored a book of the same name explaining how the game was designed, and the book includes code listings for the Apple II version. The Applesoft BASIC code can be found at taipangame.com/BASIC.txt.
