+# Steps to compile with "Microsoft C Compiler 4.00"
+
+1. Download dosbox https://www.dosbox.com
+1. Launch dosbox
+1. Use Ctrl+F12 to speed up to ~15k cycles. It speeds up builds.
+1. >MOUNT c "[Local-Directory]/SRC"
+	e.g. MOUNT c "E:\projects\u4-decompiled\SRC"
+1. Download tools
+	1. Go to https://www.pcjs.org/software/pcx86/util/other/unp/4.11/
+	1. In the dropdown under the command prompt select "UNP (Executable Unpacker) Source"
+	1. Click "Load" and then "Save"
+	1. In the dropdown select "MS C 4.00 (Disk 1)"
+	1. Rename downloaded file to MSC1.img
+	1. In the dropdown select "MS C 4.00 (Disk 2)"
+	1. Rename downloaded file to MSC2.img
+	1. In the dropdown select "MS C 4.00 (Disk 3)"
+	1. Rename downloaded file to MSC3.img
+	1. In the dropdown select "MS Macro Assembler 3.00"
+	1. Rename downloaded file to MASM300.img
+	1. Go to https://winworldpc.com/product/borland-turbo-c/2x
+	1. Download "Borland Turbo C 2.0 (3.5)"
+	1. Extract disk2.img from download and place with other img files
