 ## Coding Style
 
-Due to the nature of the project, you will find a variety of coding styles.  When making changes to existing code, please try to be consistent with the existing coding style.  You may not like the current style, but no one likes mixed styles
-in one file/module.

+styles.  When making changes to existing code, please try to be
+consistent with the existing coding style.  You may not like the current
+style, but no one likes mixed styles in one file/module.
 
-Be careful with white space.  RomWBW is primarily assembly langauge code.  The use of tab stops at every 8 characters is pretty standard for assembler.  If you use something else, then your code will look odd when viewed by others.

-In most cases, the use of `<cr><lf>` line endings is preferred.  This is standard for the operating systems of the era that RomWBW provides.  Also note that CP/M text files should end with a ctrl-Z (0x1A).  This is not magically added by the
-tools that generate the disk images.

+
+## Hints for Developers
+
+- The majority of RomWBW is assembled with TASM (and it's compatible
+  equivalent sz80as).  These tools have quirks that are very subtle.  For
+  example, TASM does not evaluate expressions in the standard way.  It
+  uses a left to right approach.  Check the TASM documentation carefully.
+
+- The following two Z80 instructions highlight a common issue with the
+  Z80 assembler syntax.  Parens in operands frequently indicate an
+  indirect reference.  To treat the operand as an expression, use the
+  second format.
+
+```
+	LD	A,(5+5)		; Load A with the value at address 10
+	LD	A,0+(5+5)	; Load A with the value 10
+```
+
+- The RomWBW documewntation in the Doc directory is generated with a
+  process outside of the normal build process.  To update documentation,
+  please update the .md files in Source/Doc.  Those are the Markdown
+  source files for the documentation.  The PDF files will be updated
+  offline from those.

+VGM File Info Scanner for CP/M
+===============================
+
+A utility that scans all .VGM files in the current directory and
+displays a table showing which audio chips each file uses.
+
+Version 1.1 uses a hybrid detection approach:
+- Checks VGM header clock values to detect chip types
+- Scans VGM command stream to detect multiple instances of same chip type
+
+Usage:
+------
+
+Simply run the program from a directory containing VGM files:
+
+    VGMINFO
+
+No command line arguments are needed. The program will automatically scan
+all .VGM files in the current directory.
+
+Output:
+-------
+
+The program displays a formatted table with two columns:
+  - Filename: The name of the VGM file
+  - Chips Used: A comma-separated list of audio chips used in that file
+
+Supported Chips:
+----------------
+
+The program can detect the following audio chips:
+  - SN76489 (PSG - Programmable Sound Generator)
+  - YM2612 (FM Synthesis chip used in Sega Genesis/Mega Drive)
+  - YM2151 (OPM - FM Operator Type-M)
+  - YM3812 (OPL2 - FM synthesis chip)
+  - YMF262 (OPL3 - Enhanced FM synthesis chip)
+  - AY-3-8910 (PSG used in many arcade and home computers)
+
+Example Output:
+---------------
+
+VGM Music Chip Scanner v1.1
+
+Filename  Chips Used
+========  =====================
+BGM       2xAY-3-8910
+ENDING    AY-3-8910
+INCHINA   YM2612
+SHIRAKAW  SN76489, YM2612
+STARTDEM  2xSN76489, AY-3-8910
+WONDER01  2xSN76489
+========  =====================
+
+Notes:
+------
+
+- The program reads the VGM file headers and scans up to 255 commands from
+  the VGM data stream for accurate chip detection.
+  
+- Files that don't have a valid VGM header are silently skipped.
+
+- Chip detection uses a hybrid approach:
+  * VGM header clock values (offsets 0x0C, 0x2C, 0x30, 0x74) determine
+    which chip types are present
+  * Command stream scanning detects multiple instances (e.g., "2xSN76489")
+
+- AY-3-8910 clock detection respects VGM version - only checked for v1.51+
+  to avoid false positives from invalid header data in older VGM versions.

-; REBOOT - Allows the user to Cold or Warm Boot the RomWBW System
-; Version 1.0 12-October-2024
-;==============================================================================
-;
-; Author: MartinR (October 2024)
-;    Based **very heavily** on code by Wayne Warthen (wwarthen@gmail.com)
-;______________________________________________________________________________
-;
-; Usage:
-;   REBOOT [/C] [/W] [/?]
-;     ex: REBOOT	Display version and usage
-;         REBOOT /?	Display version and usage
-;         REBOOT /C	Cold boot RomWBW system
-;	  REBOOT /W	Warm boot RomWBW system
-;
-; Operation:
-;   Cold or warm boots a RomWBW system depending on the user option selected.
-;
-; This code will only execute on a Z80 CPU (or derivitive)
-;
-; This source code assembles with TASM V3.2 under Windows-11 using the
-; following command line:
-;	tasm -80 -g3 -l REBOOT.ASM REBOOT.COM
-;	ie: Z80 CPU; output format 'binary' named .COM (rather than .OBJ)
-;	and includes a symbol table as part of the listing file.
-;______________________________________________________________________________

+
+The above games have been curated from here <https://eblong.com/infocom/>.
+Full game documentation can be found here <https://infodoc.plover.net/>
+
+The game files are a virtual machine code commonly known as Z-Machine, they
+are portable and will run on any machine that has a Z-Machine interpreter.
+
+* All the Z3 games come with the official CP/M interpreter (the `COM` file) 
+  version C last updated by Inforcom on 5th Feb 1985. You can simply run the
+  game by running it from the `COM` program  
+* All latter games Z4, Z5,.. and above, (Marked as * in the listing above)
+  are more sophisticated and require a better interpreter. i.e. VEZZA. 
+
+#### VEZZA (User Area 15)
+
+Vezza is a modern Infocom/Inform/Z-machine text adventure interpreter for 8 bit
+z80 based computers.  What makes it modern is that it is written in hand-crafted
+z80 assembler for maximum speed, and can load not only the classics such as
+Zork 1,2 and 3 but also the later games.
+
+It can run Z1 up to Z8 inform format interactive fiction game files. To run 
+a game with Vezza just type Vezza followed by the game you want to run. e.g.
+
+`VEZZA ZORK0.Z6`
+
+**Note:** One of the bigger constraints is available RAM. An OS such as ZPM
+since it uses banked RAM does have a good amount of available RAM and was 
+used to test these games work.
+
+This tool is free but the developer accepts your support by letting
+you pay what you think is fair for the tool. If you find this useful
+consider donating at:

+You should (test and) choose one that works on you configuration,
+and best to copy and rename it as vezza.com

+#### Compressed ROM Image File: RCZ80_ez512_std_64k.rom
+
+The RomWBW utility program 'compress' is designed to squeeze the 
+compiled RomWBW 128K file 'RCZ80_ez512_std.upd' into a 64K ROM. As there
+are many areas in RomWBW with repeating bytes of the same value, it is 
+possible to compress the 128K file to fit into a 64K ROM.
+
+The compression program looks for two or more consecutive bytes of the 
+same value (any values of $00 to $FF). If it finds duplicates, it leaves
+two of the duplicate bytes followed by a byte count, n-1 (n <= $FF), 
+where n is the total number of duplicates. If the program succeeds in 
+compressing the input file to fit into the available space, the file 
+'RCZ80_ez512_std_64k.rom' is constructed, along with a short Z80 
+decompression program that will be stored in the last 256 bytes of the 
+ROM. The constructed 64K file is saved and the unused storage space is 
+output in bytes. Should compression fail to fit the input file into 
+available space, only an error message and the overrun in bytes is 
+output.
+
+The decompression program, located at $FF00, is executed at startup via 
+the 3-byte jump at location $0000, decompressing the stored code in ROM 
+into the computer's RAM. When decompression finishes, control is passed 
+to RAM location $0000, which in turn starts execution of RomWBW.
+
+The 64K ROM Layout:
+
+* The first 3 bytes are always $C3 $00 $FF, a jump to the Z80 
+  decompression code located at $FF00 in the ROM.
+
+* Locations $0003 up to, and including, $FEFF are available to store 
+  the compressed 128K input file.
+
+* Location $FF00 up to, and including, $FFFF, is where the Z80 
+  decompression program is stored.

-## Disk Operations/Commands
-
-With some understanding of how RomWBW presents disk space to the
-operating systems, we need to go over the options for actually setting
-up your disk(s) with content.
-
-### Preparing Media for First Use
-
-You can initialize the media in-place using your RomWBW system.
-Essentially, this means you are creating a set of blank directories on
-your disk so that files can be saved there.
-This is somewhat analogous to partitioning of a hard disk
-or doing a low level format of a floppy disk.
-
-Initilizing a Floppy disk is covered in the section [Floppy Disk Formatting],
-or for a Hard disk the section [Hard Disk Preparation] covers the steps to 
-manually setup a hard disk for first use. 
-
-### Clearing (Formatting) Drives 
-
-This is somewhat analogous to doing a FORMAT operation on other systems.
-
-With RomWBW you use the `CLRDIR` command to do this.
-This command is merely "clearing out" the directory space of the drive
-referred to by a drive letter and setting up the new empty directory.
-
-Refer to $doc_apps$ for more information on use of the `CLRDIR` command.
-
-Since `CLRDIR` works on drive letters, make
-absolutely sure you know what media and slice are assigned to that
-drive letter before using `CLRDIR` because `CLRDIR` will wipe out any
-pre-existing contents of the slice.
-
-After `CLRDIR` completes, the slice should be ready to use by the operating
-system via the drive letter assigned.
-Start by using the `DIR` command on the drive.
-This should return without error, but list no files.
-
-Here is an example of using `CLRDIR`.  In this example, the `ASSIGN`
-command is used to show the current drive letter assignments.  Then
-the `CLRDIR` command is used to initialize the directory of drive 'G'
-which is slice 2 of hard disk device IDE0 ("IDE0:2").

-#### Adding Slices to Combo Image
+There are two approaches you can use to create custom hard disk
+images with multiple slices.
+
+- You can add/modify a configuration file and run the RomWBW
+  build process.  This requires running the RomWBW build process, but
+  will cause your custom hard disk images to be created with every
+  build.
+
+- You can manually combine the individual images using `COPY` (Windows)
+  or `cat` (Linux/MacOS).  This does not require running the RomWBW
+  build process, but will require manually recreating your custom
+  hard disk images when you upgrade to new releases of RomWBW.
+
+The following sections provide more detail on each approach.
+
+#### Building Custom Hard Disk Images
+
+The RomWBW build process builds the disk images defined in the
+`Source/Images` directory.  The resultant images are placed in the `Binary`
+directory and are ready to copy to your media.
+
+These aggregate disk images are defined using .def files.  You will see there
+is a combo.def file in the Images directory that defines the slices for the
+Combo disk image.  You can create your own .def files as desired to
+automatically create custom aggregate disk images.  When the RomWBW
+build process is run, it will automatically look for all .def files
+in the `Source/Images` directory and create aggregate disk images for
+each using the same base name as the .def file.
+
+There is an example of this in the `Images` directory called 
+`all.def.example`.  You can remove the ".example" suffix so that the 
+file is called `all.def`.  Now, if you run the RomWBW build process, it 
+will automatically generate `hd512_all.img` and `hd1k_all.img` files in 
+the `/Binary` directory. This example creates an aggregate disk image 
+with all of the possible slices.
+
+You could also modify the contents of the Combo disk image by simply
+modifying the `combo.def` configuration file.  However, it is recommended
+that you leave the Combo image alone and simply define your own.
+
+NOTE: All of the `hd1k_xxx.img` aggregate disk image files created in
+this way (including the Combo disk image) will already be prefixed with 
+`hd1k_prefix.dat`, so you do not need to add the prefix file.  They are 
+ready to write to your media.
