+The directories contained in the same directory as this README have all the 
+materials you shall need to develop code for your OBD0 VTEC ECU.
+
+
+THE DIRECTORIES
+
+src/ - Contains actual ECU assembly code.
+
+src/stock - Contains disassemblies of stock PR3 and PW0 ROMS.
+
+src/features - Contains stock ROMS with some extra feature added to the code
+               such as datalogging, boost, etc. If you want to develop a new
+               feature, put your code here.
+
+
+doc/ - Contains files that will help you learn about how the processor works
+       and about the code in general. See the README in doc/ for more info.
+
+bin/ - Contains the assembler and disassembler.
+
+extra/ - Contains extra things you may want to use for ECU dev such as 
+         textpad syntax hilighting.
+
+STUFF YOU SHOULD KNOW ABOUT THE ECU
+
+OBD0 VTEC ECUs use the 66301 processor. This is a very obscure 66k variant
+and there is virtually no information about it. Fortunately, it is similar
+to OBD1's 66201 processor which does have a decent amount of info available
+

+ASM.EXE

+Asm will assemble your .asm code into a usable .bin file:

+Standards for all obd0 vtec roms Ben Ogle creates. 
+
+Not all of this will be present in all roms. This document
+helps me to not overwrite already used rom locations. It
+is here to hopefully make ALL new asm code compatible 
+with all other new asm code from the editor standpoint.
