The C64 Mini Adding Flags to Image Files

The C64 Mini can set all kinds of settings through the use of .CJM files, however, what if you just have a single problematic game and don’t really want to configure a whole .CJM file? There is a older method that works with the mini called Flag Configuration.

How it works: At its most basic, it is simply renaming a file and adding an underscore (_) and a two capital letter tag to the end of the file name.

Example: Jupiter-lander.d64 —> Jupiter-lander_J1.d64

The above example tells the mini that this file is a joystick port 1 game.

SIDE NOTE: The ports on the Commodore had to be addressed directly from code so some games used joystick port 1 and most others used joystick port 2.

Commodore 64 joystick control ports.

You can add any number of flags in any order to the end of the file. It should be noted that if your game has underscores in the name, you may have to remove those as well for this to work.

Example: The Jupiter Lander file is a PAL joystick 1 image you want to run on an NTSC system. It doesn’t load properly so you want to turn the cycle accurate disk reader on (use Accurate Disk Drive Mode).

Jupiter-lander.d64 —> Jupiter-lander_TPJ1AD.d64

Flag Key

J1This sets the primary joystick port as port 1. With a second Joystick connected, it automatically uses port 2.Use this flag if you cannot use a joystick with a game you know should work with one.
J2This sets the primary joystick port as port 2. With a second Joystick connected, it automatically uses port 1.Port 2 is the default for the Mini so it does not need to be set.
ADStands for “Accurate Disk”. Turns on the cycle exact disk reader on the Mini.Use this if your game is unstable when you try to run it.
ROThis makes the disk image read-only. This is mainly for protection, however, some games did check this for copy protection.
NI“No Indicator” turns off the drive access indicator.Mainly a user preference thing.
TNTells a PAL (European) system that the disk image is NTSC (Japan and North America).Use if you are running a PAL system with an NTSC image or the game play seems too slow.
TPTells an NTSC (Japan and North America) system that the disk image is PAL (European).Use if you are running a NTSC system with an PAL image or the game play seems too fast.

This information is found in more detail here under Appendix A.

Technical Note: “Accurate Disk” does slow the loading of games down, however, it does not turn off the “fast loader” on the C64 Mini. Before loading your ROM or disk image, press the third button on the C64 Mini to turn off Fast Load.

C64 Mini CJM files Reference

The C64 Mini is a fun and useful machine for those wanting to relive the experience of the Commodore 64. However, the C64 Mini uses emulation to run games. This means it behaves differently than a full-fledged Commodore 64 and, as a result, games designed for the system do not always behave the same way they would when running on original equipment.

The way they found to get around a lot of these issues was the .CJM file. This is a simple text file that, when formatted properly, will tell the Mini how to operate with certain games. 

There is a tool to help you do this here that automates a lot of the process. This site also has pre-configured CJM files to download.

While it is not necessary to write the configuration file yourself, it should be well documented in the event that this tool no longer is available. Let’s start by taking a look at an existing .CJM file.


NOTE: You will need to name the file EXACTLY the same name as the image file. (Ex. Jupiter_Lander.d64 –> Jupiter_Lander.cjm)

X: System options
Each one of these is either on or off. Remove the option to disable. NOTE: These X: values are case sensitive and must be in all lower case.

ntsc: This is the video display type the game requires. Options are: ntsc or pal. Remove to use the default (native) display.
accuratedisk: This turns off the cycle exact floppy emulation in the mini. Use this option if the game hangs or crashes while loading.
Note: Accurate Disk does slow down loading but it does not control the Mini’s fast loader. To disable that, press the third button (C) on the Mini Joystick before loading your ROM or disk image. 
Marks the disk image read-only. Required for some disk images and copy protection.
driveicon: Displays a drive icon while the image is being accessed.

J: Joystick Mapping
Each one of these options is required – even if the joystick doesn’t have a button for the function.

V: Vertical Video Offset
This is simply a positive or negative integer to move the video up or down.

This should give you enough info to remap joystick and set system options. 

Example 1: You have a PAL game that is not designed for a joystick but instead uses WASD and the Right Shift for joystick control.


Example 2: You want to turn on the access indicator and map the second joystick button to Space on the second joystick and make it default.


Using The File

Place the file in the same folder as your game. The mini looks for the .CJM file automatically. 

Applying to Multiple Games

You can apply the file to multiple games in a folder by renaming the file to THEC64-default.cjm

This information is found in more detail here under Appendix A.

Reset Samsung DVR to Factory

micro server 2 RAID

I recently had a customer ask me to reset a Samsung DVR. Of course,  I first checked to see if there was a hardware switch to reset it. There wasn’t.

Googling the reset procedure, I discovered all of the resets for Samsung DVRs were pressing a combination of buttons on the front of the machine or remote. My machine had no buttons and none of the combination of buttons worked.

I did find a YouTube video that had a 7th combination of buttons that did work. This combination should work for SDR-3300N or the SDR-3040N and perhaps a few others.

On the remote, press:


in quick succession. I was able to get it on the first attempt. It will prompt you to reset to factory which you select OK.

Special thanks to 4k Vlogs for the info.

NVR Can Record Your Phone Camera

Gigabytes NVR can record IP and web cameras at megapixel resolutions. With the help of an app, you can now record your phone camera using the Gigabytes NVR.

How did we do it?

First, you have to install a program called IP Webcam from Google Play. There is a pro version that removes ads, etc. but, for testing, we went with the free version.

After that, we configured a few things, played with some settings, but we essentially just pressed start. The video url was http://IP.ADD.RE.SS:8080/video.

We will post this information on our NVR IP Camera Compatibility page.

Neat, huh? Why would anyone do that?

For several reasons.

  1. Automatic pictures. Let’s say you want pictures of a particular landmark. You can set the NVR on snapshot mode and take 1 picture every second from your phone and send it to your desktop.
  2. Personal security. With the help of a proxy like the DynDNS client, you can walk around and capture video of a place you are visiting. If you are the victim of a crime, your phone can be a silent witness.
  3. Phone security. If your phone gets stolen, you will have video of who stole it.
  4. Dashcam anyone? No need to buy a separate device. Capture your road trip or commute. If your phone is lost or damaged in an accident, you will still have documentation of the crash.
  5. No more missing out. No more “Man! I wish I had my camera!” moments.
  6. Baby monitor or home security. No need to buy a camera. Just use an old android device.

NVR: Drive Full, not recycling

Relates to: Gigastrand and Next Level NVR Software

We have seen where the drive appears to fill up but there is no apparent reason for the drive being full. Three of the reasons we have seen so far are caused by 4 different but related issues.

  1. Apache errors – for some unknown reason, the Apache log file (located in /var/log/apache2/) sometimes grows to an incredible size. Deleting the log file resolves this issue.
  2. Virtual Ramdisk error – The Gigastrand NVR has a virtual ramdisk where it caches images. Sometimes (especially if the motion daemon is fiddled with) the ramdisk will start writing to the user folder. Deleting the files and and NVR restart will resolve that issue as well.
  3. Storage Limit – If you have a full complement of cameras, the default storage size of 20Gb will fill up very fast (less than 12 hours in some cases). This is too fast for the machine to effectively clean up. This issue manifests itself in the same way as the other 2 issues, but the system is essentially working.

To fix this issue, edit the /etc/kmotion/kmotion_rc file and change the images_dbase_limit_gb to something higher than 20Gb but less than your total available storage. Do an NVR Restart to make the changes go into effect.

Give Gigastrand OS about 64Gb in your storage calculations. Subtract that from your total drive space so that it does not interfere with your video storage.

4. Firefox – If you use live view on the NVR regularly, Firefox will save all the images it downloads in /home/user/.cache/mozilla/firefox/[profile].default/cache2/entries/. Clear this out first. Then, open Frefox and go to menu>Preferences>Privacy. Under History click Never Remember History. Close Firefox and restart the computer.
