RetroPie Install Guide

Posted on June 19, 2019 by Managed WordPress Migration User

Hardware Used (Total Cost $178)

You can easily go cheaper on the hardware by getting USB controllers, getting a smaller MicroSD card, using an existing USB keyboard, not using the optional fan, etc. However, at minimum I would recommend the RaspberryPi v3 Model B+ (Latest as of this writing) and the Retroflag case!

CanaKit RaspberryPi Version 3 Model B+, heatsink kit, and 2.5A Power Supply
- $49 on Amazon
SanDisk Ultra 128GB microSDXC UHS-I Card with Adapter, Black, Standard Packaging (SDSQUNC-128G-GN6MA)
- $20 on Amazon
Retroflag NESPI Case Plus
- $24 on Amazon
- This is an exact mini replica of the original NES with function power & reset buttons. They also make other replica game system cases, visit http://www.retroflag.com for the full list
Optional: Pi-Fan
- $5 on Amazon
2 x 8Bitdo Sn30 Bluetooth Gamepad

Clean No-Intro 2018 ROM Set

Posted on June 19, 2019 by Managed WordPress Migration User

Overview

I did not want my RetroPie to be cluttered with ROMs I did not want. I only wanted the original games, I did not want duplicates or revisions, and I only wanted games in English so I could read the on screen text. For example, the NES has about 716 officially licensed games and the No-Intro 2018 ROM set has about 2,748 games in it. I wanted to reduce that number down closer to the officially licensed games count to save space on my MicroSD card and reduce the amount of ROMs I would have to scroll through each time. I decided to create the below powershell scripts based on the No-Intro 2018 ROM set to accomplish my goal, which I’ll explain each step in detail.

Download all of the scripts below in a zip file:

http://sigkillit.com/wp-content/uploads/2019/06/Clean-NoIntro2018.zip

Phase 1: Determine What ROMs to Keep

The No-Intro 2018 ROM set includes the following game systems that are compatible with RetroPie/Emulationstation:

Atari: 2600
Atari: 5200
Atari: 7800
Atari: Lynx
Bandai: WonderSwan
Bandai: WonderSwan Color
Coleco: ColecoVision
GCE: Vectrex
Microsoft: MSX
NEC: PC Engine / TurboGrafx 16
Nintendo: Family Computer Disk System
Nintendo: Game Boy
Nintendo: Game Boy Advance
Nintendo: Game Boy Color
Nintendo: Nintendo 64
Nintendo: Nintendo Entertainment System
Nintendo: Super Nintendo Entertainment System
Nintendo: Virtual Boy
SNK: Neo Geo Pocket
SNK: Neo Geo Pocket Color
Sega: 32X
Sega: Game Gear
Sega: Master System / Mark III
Sega: Mega Drive / Genesis
Sega: SG-1000

The No-Intro ROMs follow a pretty standardized naming scheme such as:

Battletoads (Europe).zip
Battletoads (Japan).zip
Battletoads (USA).zip
Captain Skyhawk (Europe).zip
Captain Skyhawk (USA) (Rev A).zip
Captain Skyhawk (USA).zip

As you can see, the base name of the ROM is followed by detailed descriptions such as the region released, revision, language, etc which is contained in parentheses. The first step is to get a unique list of all of the information contained in the parentheses for each game system so we can determine what we want to keep. In the below script, modify $global:romNoIntroDirectory to point to the root directory of your No-Introl ROMs. The script will then output the unique results by game system as well as a combined list.

As you can see from the output, there are some inconsistencies in the naming conventions such as (Rev 1) vs (Rev A) OR (Rev 1.2). However, we now have all of the necessary information to choose the ROMs we want to keep.

Phase 2: Create the No-Intro 2018 ROM Set Clean Up Scripts

The cleanup script is broken down into 4 main parts:

Get List of ROMs and Unique ROMs in the original No-Intro 2018 ROM set. We can use this list to determine which ROMs to keep and to keep count
Remove Exceptions from the list based on the results from the Get-NoIntroExceptions.ps1 script. This will help speed up things up by reducing the # of ROMs we need to process
Identify a Primary ROM to Keep and Remove Duplicates from the list based on the results from the Get-NoIntroExceptions.ps1 script
Copy the No-Intro ROMs to keep from our list to a new directory

Since each game system varies on what I wanted to keep, I decided it would be best to create a separate script for each system based on the same template. This way, I could easily customize what I wanted per system. For example, Japan games on NES tend to be in Japanese but on the FDS they are in English. Below is the template used as well as an explanation on how to configure it followed by my customization for each system.

Clean-NoIntroRomsTemplate.ps1

For each system, you will want to customize the following:

$global:scriptDescription = What the script does
- Ex: Cleanup Nintendo Entertainment System No-Intro 2018 ROMs
$global:romNoIntroDirectory = No-Intro 2018 Game System ROM Directory
- Ex: C:\Games\No-Intro 2018\nes\
$global:romCleanDirectory = Directory to copy No-Intro ROMs to
- Ex: C:\Games\RetroPie\nes\
$global:romsDoNotDelete = Add full name of any ROM to want to keep, even if it matches an exception or is not the primary ROM
- Ex: Castlevania (USA) (Rev A).zip
$global:romsExceptions = Any ROM containing any of these will not be copied unless specified in “$global:romsDoNotDelete”
$global:romsSortOrder = When there is more than 1 version of a ROM, it uses this preferred matching order to determine the Primary ROM to keep. If it does not match anything, it will determine the Primary ROM as the first alphabetical result

#Global Variables
#- Modify: scriptVersion, scriptDescription, romNoIntroDirectory, romCleanDirectory
#- Add/Modify: romsDoNotDelete, romsExceptions, romSortOrder
$global:scriptVersion = "v4.0"
$global:scriptDescription = ""
$global:romNoIntroDirectory = ""

$global:countTotal  = 0
$global:countUnique = 0
$global:countExceptionsDeleted = 0
$global:countDuplicatesDeleted = 0
$global:countNonDuplicatesDeleted = 0

#Any Exact ROM Name (Including Extension) In This List Will Not Be Deleted
#-ROMs listed here will NOT be deleted even if they match a value in romsExceptions

#-ROMs in romsExceptions will not be deleted even if it is not determined as the primary

#-ROMs in romsExceptions will not be deleted even if it is not determined as the primary
#-Ex: "Joust (USA).zip" would be primary over "Joust (Japan).zip"

Remove RDS CALs from RDS Server

Posted on August 31, 2017 by Managed WordPress Migration User

Background

There are many circumstances where you will need to remove a RDS CALs from an RDS Server, or in some cases you want to rebuild the entire RD licensing database. Microsoft allows you to remove an individual CAL license pack using powershell, or rebuild the entire database. However, if neither of those work, it’s quite easy to manually rebuild the RD licensing database. I’ve included directions for all 3 methods below, and have tested this on Windows Server 2008, 2008R2, 2012, 2012R2, and 2016.

Remove An Individual RDS CAL License Pack Using Powershell (User or Device CAL)

Open powershell elevated as an administrator
Type the following command to list the RDS Licenses and note the KeyPackID
- Alternatively, open RD Licensing Manager and note the Keypack ID

Get-WmiObject Win32_TSLicenseKeyPack

1	Get-WmiObject Win32_TSLicenseKeyPack

Run the below command to remove the licenses pack from your RD Server
- Replace KEYPACKID with the number you obtained above

wmic /namespace:\\root\CIMV2 PATH Win32_TSLicenseKeyPack CALL UninstallLicenseKeyPackWithId KEYPACKID

1	wmic /namespace:\\root\CIMV2 PATH Win32_TSLicenseKeyPack CALL UninstallLicenseKeyPackWithId KEYPACKID

Rebuild the RD Licensing Database

Microsoft provides directions on how to do this automatically, via a web browser, or via the phone:

https://technet.microsoft.com/en-us/library/dd851428.aspx

Manually Rebuild the Licensing Database (Guaranteed to Work if the Previous 2 methods Fail)

Make sure you have documentation of your MS License agreement that includes Authorization number, License number, License type (User/Device CAL), and Quantity before proceeding
Stop the Remote Desktop Licensing service

Rename C:\Windows\System32\lserver\TLSLic.edb to C:\Windows\System32\lserver\TLSLic.old
Start the Remote Desktop Licensing service
All licenses will now be cleared out of RD Licensing Manager, and you’ll need to re-install the licenses you want to add back in

Missing Power and Search Button On Start Screen

Posted on October 28, 2016 by Managed WordPress Migration User

Missing Power and Search Button On Start Screen on Server 2012 R2 and Windows 8.1

Recently, after installing a Windows 2012 R2 Server VM, I noticed the Start screen was missing the Power and Search buttons. All of my older Server 2012 R2 Server VM’s had the Power and Search button on the start screen, I used the same ISO to install, and Windows was 100% up to date. After researching, this issue can affect Windows Server 2012 R2 as well as Windows 8.1. Here is a screenshot of my Start screen missing both the Power and Search buttons:

The Solution

The short answer is KB2919355 needs installed. HOWEVER, you need to make sure you install the following updates in this order:

Prerequisite: KB2919442
Install KB2919355 that has multiple downloads in it, which can be directly downloaded from the Microsoft Download Center
1. Windows 8.1 x86
2. Windows 8.1 x64
3. Server 2012 R2 x64
4. NOTE: Once downloaded, these updates need installed in the following order
  1. clearcompressionflag.exe
  2. KB2919355 (Reboot after installation, if fixed you can skip the rest)
  3. KB2932046
  4. KB2959977
  5. KB2937592
  6. KB2938439
  7. KB2934018

Once KB2919355 is installed and you reboot, you should now see the Power and Search buttons on the start screen as displayed below:

Final Notes

Once KB2919355 is installed, run Windows Updates and you’ll probably need to install a few hundred updates again

Move Off-Screen Window in Windows

Posted on September 22, 2016 by Managed WordPress Migration User

Have you ever had a window that ended up off of your screen and were unable to move it back into view? I’ve personally had this occur after disconnecting a monitor from my laptop which I had my desktop extended on. However, there’s a simple trick to move the Window back into view of your desktop.

Make the Off-Screen Window Active

Hold the Alt key down and then press Tab key until you’ve selected the Window that is off-screen

Select Move for the Active Window

Hold the Alt key down, press the Space-bar key, then press the M key

Move Your Window Back Into View

You can now move the window in the desired direction with the arrow keys

365 Password Generator

Posted on July 14, 2016 by Managed WordPress Migration User

This powershell script bulk generates passwords in a similar style as the password generator in Office 365. The passwords begin with a capital letter, followed by 5 lower case letters, and 2 digits at the end. You can modify the pattern to suite your needs (Note: It’s using the ASCII table ranges as the set it randomly chooses from).

Function Generate365PW
{
	Param($max = 1)
	For ($i = 0; $i -lt $max; $i++){
		$pw = Get-Random -Count 1 -InputObject ((65..72)+(74..75)+(77..78)+(80..90)) | % -begin {$UC=$null} -process {$UC += [char]$_} -end {$UC}
		$pw += Get-Random -Count 5 -InputObject (97..122) | % -begin {$LC=$null} -process {$LC += [char]$_} -end {$LC}
		$pw += Get-Random -Count 2 -InputObject (48..57) | % -begin {$NB=$null} -process {$NB += [char]$_} -end {$NB}

Determine If Distribution Group is Being Used in 365 Exchange

Posted on March 3, 2016 by Managed WordPress Migration User

“What distribution groups are in use?” and “How many emails are sent to a specific distribution group per month?” are common questions I receive with 365 Exchange or Exchange. Unfortunately, there is nothing built in that tracks how many emails on sent to a distribution group. However we can use Get-MessageTrace to count the number of messages sent to a distribution group for a time range with the max being 30 days. Also note, the by default PageSize returns 1000 items but you can increase the PageSize to 5000 items. For example, to get the number of emails sent to the distribution group everyone@domain.com for a single day we can use:

$DGCount = Get-MessageTrace -PageSize 5000 -RecipientAddress "everyone@domain.com" -StartDate ([DateTime]::Today.AddDays(-1)) -EndDate ([DateTime]::Today) | ForEach-Object {$count++}
$DGCount

1 2	$DGCount = Get-MessageTrace -PageSize 5000 -RecipientAddress "everyone@domain.com" -StartDate ([DateTime]::Today.AddDays(-1)) -EndDate ([DateTime]::Today) \| ForEach-Object {$count++} $DGCount

Using this method, we can count the number of emails sent to each distribution group each day and store the results in an output file. We can then query those output files and create a report. In my example, the report will show the total emails sent to each distribution group by month and go back 12 months. Now without further ado, let’s get to the two scripts needed.
