  • Page 14: On-Boarding

    MEGA65 Welcome Guide 3.2 On-boarding When you turn your MEGA65 on for the first time, it prompts you for some initial settings. The most important setting is the video mode. Use the Tab key to cycle between digital video without sound over HDMI vs. with sound over HDMI (“enhanced”), and PAL 50Hz vs.

  • Page 16 MEGA65 Welcome Guide ment is similar to the Commodore 64 and 128, where you can give the computer commands, write programs in the BASIC programming language, and load and save programs. Tip: The User’s Guide does an excellent job describing the BASIC environment. See chapter 3, starting page 9. The demonstration menu is itself a BASIC program! When you exit from the menu to BASIC, this program will still be in memory.
  • Page 17: The Freeze Menu

    3.5 The Freeze menu The MEGA65 spends most of its time behaving as a Commodore 65 computer would, either running a program or awaiting instructions in the BASIC environment. Your MEGA65 has additional features that were not part of the original C65 design.
  • Page 18: Disk Images

    MEGA65 Welcome Guide There are many useful features in the Freeze menu. Try them out! One feature to remember when playing games is the “(J)OY SWAP.” This causes the two joystick ports to trade numbers. If you have a joystick in port 2 and you start a game that expects a joystick in port 1, instead of disconnecting and reconnecting the joystick, open the Freeze menu, press J to swap the port numbers, then resume your game.
  • Page 19 MEGA65 Welcome Guide 3. Use the cursor keys to navigate to DEMOCOMP.D81. Press Return to select it. 4. Notice that the disk image name appears under the “Internal drive” in the Freeze menu. 5. Press F5 to reset with this disk image in the virtual drive. Tip: If you are mounting a disk to start a new program, use the F5 key to exit the Freeze menu with a reset.
  • Page 20: Loading And Running A Program From Disk

    MEGA65 Welcome Guide 3.7 Loading and running a program from disk You now have the DEMOCOMP.D81 disk image mounted to device 8 (drive 0). Let’s see what’s on the disk! Enter the following command at the BASIC READY. prompt: This lists all of the files on the disk, also known as the disk directory. You can use the LOAD command to load a program off of the disk by name: LOAD "NOVDEMO"...
  • Page 21 MEGA65 Welcome Guide Tip: A common trick you may remember from your Commodore 64 is, instead of typing the full filename of something you wish to LOAD, you can list the directory of the disk, then move the cursor up to the line with the name of the program and type LOAD at the beginning of the line to form the command.

  • Page 23: Commodore 64 Mode

    When you’re done enjoying the demo, you can press the reset button, or use the Freeze menu and press F5 to reset. 3.8 Commodore 64 mode Like the Commodore 65 on which it is based, the MEGA65 can run in a Commodore 64 compatibility mode. From BASIC, enter this command, then type YES to confirm:...
  • Page 24 MEGA65 Welcome Guide The Freeze menu is accessible when in C64 mode, and can be used to mount D81 disk images (or the physical disk drive) with disks containing C64 software. MEGA65 includes a D81 disk image with C64 games and demos, named C64.D81. Use the Freeze menu to mount it to the first drive, then resume C64 mode.

  • Page 29: Important Concepts

    CHAPTER FOUR IMPORTANT CONCEPTS Now that you’ve had a taste of what the MEGA65 can do, it’s time to prepare your computer for long term use. But first, let’s discuss some important concepts of how the MEGA65 works. 4.1 SD memory cards The MEGA65 uses an SD memory card for its primary data storage.
  • Page 30: Cores

    MEGA65’s FPGA is programmed to behave like the complete collection of ICs you would find in a Commodore 65: the CPU, video and sound chips, and so on.
  • Page 31: Roms

    MEGA65 Welcome Guide 4.3 ROMs While the core recreates the hardware of the Commodore 65, the ROM recreates the built-in software of the Commodore 65. This software interfaces with the hardware and provides built-in functionality like BASIC programming. The original Commodore 65 kept its software on a physical Read-Only Memory (ROM) chip. With MEGA65, this software lives in a file on the SD card named MEGA65.ROM.
  • Page 32 MEGA65 Welcome Guide The chances are good (though not guaranteed!) that the monitor you are using with your MEGA65 can support the video signal it outputs in either mode, possibly with some manipulation of the image to account for the differing image heights.
  • Page 33: Determining The Versions Of Things

    CHAPTER FIVE DETERMINING THE VERSIONS OF THINGS The MEGA65 core (which includes the Hypervisor), ROM, and Freeze menu are all upgradable components. It is often useful to know which versions of these components are currently operating your machine. 5.1 The MEGA65 core version One way to determine which version of the MEGA65 core is installed is to turn off the computer, then hold the Ctrl key while turning on the computer to pause the Hypervisor screen.
  • Page 34: The Mega65 Rom Version

    Alternatively, you can see the version of the MEGA65 core while the computer is running without turning it off. At any time with the MEGA65 core running, hold the Mega key (the fancy M in the lower left of your keyboard) and press Tab.
  • Page 35: Opening The Mega65 Case

    CHAPTER OPENING THE MEGA65 CASE Your MEGA65 consists of an injection molded plastic case, built-in keyboard and disk drive, ports for peripherals, and internal components. The case is designed to be opened by its owner if needed. You may want to open the case for the following reasons: •...
  • Page 36 MEGA65 Welcome Guide The case separates into a top piece and a bottom piece. The keyboard is attached to the top, while the disk drive, ports, and main board are attached to the bottom. The keyboard is connected to the main board with a ribbon cable. Chapter 6.

  • Page 41: Accessing The Mega65 Filehost

    CHAPTER SEVEN ACCESSING THE MEGA65 FILEHOST The MEGA65 Filehost website is the official repository for MEGA65 firmware and ROM updates, tools, games, appli- cations, and documentation. Most files are publicly available, but a few important files require an account and verification of ownership to access. Specifically, the ROMs based on the original C65 contain material that is only licensed to owners of the MEGA65.
  • Page 42 MEGA65 Welcome Guide 4. In the dialog that opens, enter the nine-character registration code that was included with your MEGA65 on a piece of paper. It looks something like 123-ABC-456. 5. Open the menu again and “Logout,” then “Login” again. To verify that you can see the licensed files, click “Files,”...
  • Page 43: Setting Up The Microsd Card

    CHAPTER EIGHT SETTING UP THE MICROSD CARD Your microSD card will be your MEGA65’s primary storage, and the primary way to transfer files to and from your PC. You will use it to update the firmware and store updated system software and ROMs. You will also use it to manage D81 disk images and store applications you have downloaded.
  • Page 44: Updating The Sd Card Essentials

    MEGA65 Welcome Guide The SD card utility will look for cards in the available slots. Confirm that it has detected your microSD card correctly, then select option 1 for the external microSD slot (press 1). Follow the prompts. The MEGA65 formats the SD card, erasing all of its data. It also writes the factory-installed ROM files, the demo disk image, and a few other things.

  • Page 47: Updating The Core Firmware

    CHAPTER NINE UPDATING THE CORE FIRMWARE A new version of the MEGA65 core has been released since the batch #1 MEGA65 was produced, so you will want to update it. The newest ROM expects the new core. 9.1 Downloading the latest MEGA65 core You can download the latest MEGA65 core from Filehost.
  • Page 48 MEGA65 Welcome Guide Core 0 is always the factory-installed core and cannot be overwritten. This can help you restore your MEGA65 to a working state if something goes wrong with updating a core. If this is your first time seeing the core selection menu, slots 1 through 7 should be empty.
  • Page 49 MEGA65 Welcome Guide The flashing process takes a minute or so. When it is complete, you’ll see the message, “Flash slot successfully updated,” and the border will twinkle. Press any key to return to the core selection menu. Finally, press 1 (without Ctrl) to start the system with the new core.

  • Page 58: Using An External Disk Drive

    MEGA65 Welcome Guide Tip: Until this is fixed in a future software update, an HD disk with the hole exposed will not work with the MEGA65. If your disk isn’t working, double-check that the hole is covered. Using the physical floppy drive is similar to using a disk image. Open the Freeze menu (hold Restore, then release), then select drive number 0.
  • Page 59: Converting A D64 To A D81

    MEGA65 Welcome Guide 10.5 Converting a D64 to a D81 You can find almost every game and application written for the Commodore 64 online in the form of disk images. However, these disk images are typically in the D64 format, which represents a 5-1/4” floppy disk. If you want to try running a C64 application on your Mega65 in its C64 mode, you must first convert the D64 image to a D81 image.

  • Page 61: Using The Jtag Connector

    CHAPTER ELEVEN USING THE JTAG CONNECTOR The MEGA65 main board has a 12-pin JTAG connector, a standard for connecting test equipment to devices. It is not intended for regular users of a device—but we MEGA65 owners are not regular users, are we? With a JTAG USB adapter and software available on Filehost, you can connect your PC directly to the main board to: •...

  • Page 63: Installing The Jtag Adapter

    MEGA65 Welcome Guide 11.2 Installing the JTAG adapter You will have to open the MEGA65 case to connect the adapter to the 12-pin JTAG connector on the main board, in the back right corner. (See for an annotated photo of the main board.) The adapter connects Opening the MEGA65 case with the mini-USB connector facing to the right.
  • Page 64 MEGA65 Welcome Guide Use a pin or a small screwdriver to set the DIP switches on the connector to left, right, right, left, as shown. This configures the adapter to draw power from the USB connection. (Other documentation suggests left, right, left, right, which draws power from the MEGA65.
  • Page 65 MEGA65 Welcome Guide Connect a mini-USB cable to the JTAG connector, and run the cable out the back of the MEGA65 case. You can feed it out the cartridge port (potentially blocking access to the port), or punch out one of the unused port covers in the back case.

If you’re on a Mac, you will need to install a library called libusb. Install the Homebrew package manager if you don’t already have it installed, then run this command:...
  • Page 72 MEGA65 Welcome Guide 4. Follow the prompts. When prompted, turn your MEGA65 on. If everything is working, the Connection Wizard will detect the connection and close the window. If the window doesn’t close in a few seconds, click Abort and proceed with setting up the connection settings manually.
  • Page 73 MEGA65 Welcome Guide Tip: In my case, I discovered that the connection would not work if the USB cable was connected to my USB hub. Connecting directly to the USB port on my laptop resolved the issue. 11.3.2 Sending data to MEGA65 The M65Connect app can send data directly to the MEGA65’s memory.
  • Page 74 MEGA65 Welcome Guide • It’s ugly, but it works! BIT: • Sends a .BIT bitstream file, and resets using this file as the core. • Note that this takes the .BIT file, not the .COR file. Most cores provide files in both formats. •...
  • Page 75: The M65 Command Line Tool

    MEGA65 Welcome Guide Caution: Many of these upload actions reset the MEGA65 in the process, and will not warn you. Make sure you don’t have any unsaved data. 11.3.3 Transferring files to and from the SD card You can also upload files directly to the SD card. Click SD CARD to open the file transfer utility on both your PC and the MEGA65.

  • Page 81: Video Display Compatibility

    CHAPTER THIRTEEN VIDEO DISPLAY COMPATIBILITY The MEGA65 has two video outputs: one HDMI and one VGA. They mostly work as you would expect, though it may take some fiddling to display the MEGA65 image in a proper aspect ratio. Some vintage displays have caveats. 13.1 HDMI (DVI) If you connect the HDMI output to a modern HDMI-capable monitor, you will have a good time.
  • Page 82 MEGA65 Welcome Guide Chapter 13. Video display compatibility...
  • Page 83 MEGA65 Welcome Guide Without setting the aspect ratio, most widescreen monitors will stretch the image horizontally to fit. This is undesirable in most cases, but I actually quite like how 80-column BASIC looks when stretched. 13.1. HDMI (DVI)
  • Page 84 MEGA65 Welcome Guide Chapter 13. Video display compatibility...
  • Page 85 MEGA65 Welcome Guide Just for fun, here is what 80-column BASIC looks like stretched on a Dell 34” curved ultra-wide display: 13.1. HDMI (DVI)
  • Page 86 MEGA65 Welcome Guide If your HDMI display supports audio, enable “Enhanced (with audio)” mode in the MEGA65 configuration. Otherwise set it to “DVI only (no audio).” Note: As of this writing, the Hypervisor utility menu, Configuration, SD card utility, and core selection screens use “Enhanced (with audio)”...
  • Page 87: Vga

    MEGA65 Welcome Guide 13.2 VGA If you connect the VGA output to a vintage VGA CRT monitor, you will have a good time. The VGA signal and the expected aspect ratio go well together. The MEGA65 outputs a VGA image with a 31 kHz horizontal scan rate. Tip: Be sure to disable CRT emulation in the MEGA65 configuration when using an actual CRT.
  • Page 88: 4:3 Flat Panel Displays

    MEGA65 Welcome Guide 13.3 4:3 flat panel displays If you’re looking for the 4:3 aspect ratio of a vintage monitor that won’t distort the MEGA65 image but also want the convenience of a flat panel screen, there are options, with caveats that depend on the model of monitor you find. Flat panel displays of the early 2000’s ushered out bulky CRTs before widescreen aspect ratios came into fashion.
  • Page 89 MEGA65 Welcome Guide Why use both HDMI and VGA connections with the same display? In the case of the 2001FP, I need both to work 13.3. 4:3 flat panel displays...
  • Page 90 MEGA65 Welcome Guide around caveats with each mode: • HDMI provides the highest quality display for regular use. Some of the utility menus (configuration, core selec- tion) use the “Enhanced (with audio)” HDMI mode, which fails to display through the 2001FP DVI input. These menus work fine over VGA.
  • Page 91 MEGA65 Welcome Guide With both video outputs connected, I can switch the monitor input as needed without too much hassle. The HDMI-to-DVI cable does not carry the HDMI audio signal, and the Dell 2001FP doesn’t have built-in speakers anyway. I use a Dell soundbar and a separate speaker connection to the MEGA65 audio jack. Tip: Is your HDMI output not working with a vintage DVI display? Double-check that you have “DVI only (no audio)”...
  • Page 92: Video Capture Cards

    MEGA65 Welcome Guide 13.4 Video capture cards One advantage to having two simultaneous video outputs is you can send one to a monitor and another to a device such as a video capture card. I used VGA to the Dell and HDMI to an Elgato Camlink to take the screenshots in this Guide.

    CHAPTER FOURTEEN RECENTLY ADDED FEATURES The MEGA65 batch #1 shipped from the factory with ROM version 920287, and a User’s Guide printed in late 2021. The MEGA65 team has been enhancing the ROM with new features and improvements. As of 2022, the ROM is still considered a work in progress, and MEGA65 owners are encouraged to update to the latest ROM.
  • Page 94: New Basic Commands

    MEGA65 Welcome Guide 14.2 New BASIC commands Many new BASIC commands have been added to the factory-installed ROM, or have been added to the User’s Guide since it was printed. See the latest User’s Guide for specifics. New commands include: 14.2.1 Newer disk commands MOUNT controls the mounting of disk images and drives to the unit numbers from BASIC, without having to enter the Freezer.
  • Page 95 MEGA65 Welcome Guide 14.2.2 Newer graphics commands CUT, GCOPY, PASTE act on a rectangle of a graphics screen as a clipboard. GCOPY copies a rectangle of pixels to a buffer; CUT copies the rectangle then fills with the color of the pen. PASTE paints the previously copied rectangle onto the screen at a given location.
  • Page 96 MEGA65 Welcome Guide 14.2.4 Other newer BASIC features The FREEZER command opens the Freeze menu, as if you pressed Restore for a second. The INFO command prints useful information about the system and available BASIC memory. Tip: For bleeding edge information about new BASIC features as they stabilize and get added to the documentation, the mega65-user-guide Github repo commit list.

    CHAPTER FIFTEEN KNOWN HARDWARE ISSUES Batch #1 of the MEGA65 hardware shipped to owners in May of 2022. Thanks to the tireless efforts of the MEGA65 team over many years, the result was of satisfyingly high quality, a device that recalls the vintage 8-bit machines of the 1990’s while retaining modern advantages like quality key switches.
  • Page 98: Keyboard Slouching And Sticking Help Key

    MEGA65 Welcome Guide 15.3 Keyboard slouching and sticking Help key My MEGA65 arrived with its keyboard appearing to slouch below the top case a bit on the right-hand side, and others reported something similar. The spacebar appeared not vertically straight with the top case, and some people reported that the Help and F13 keys get stuck on the top case when pressed all the way down.
  • Page 99: Questions And Answers

    CHAPTER SIXTEEN QUESTIONS AND ANSWERS Here are a few additional common questions about the status of MEGA65 features. 16.1 Does the cartridge port work? Yes. If a Commodore 64 cartridge is in the MEGA65 cartridge port when the MEGA65 is turned on, it will attempt to start in C64 mode and execute the cartridge.
