<p>The Game Boy is a portable game console released by Nintendo in 1989. It was followed by the backwards compatible Game Boy Color in 1998. It is best known for making Tetris a pop culture phenomenon in the early Nineties.</p><p><a href="https://en.wikipedia.org/wiki/Game_Boy">https://en.wikipedia.org/wiki/Game_Boy</a></p><img loading="lazy" src="gbc07.jpg" data-is-external-image="true">
<p>This early Core for the MEGA65 has some minor shortcomings. As C64-Joysticks officially only have one button, you can map the Game Boy buttons <kbd>A</kbd> or <kbd>B</kbd> to <kbd>Joystick Up</kbd> so that you can play jump and run games as you would on a C64. All Game Boy buttons, including <kbd>Start</kbd> and <kbd>Select</kbd> can be pressed via the MEGA65 keyboard.</p><p>The Core can load ROM files for the Game Boy and Game Boy Color. It features an unlicensed BIOS that can be replaced by the user with official BIOS files.</p><p>For further instructions please read:</p><p><a href="https://github.com/sy2002/gbc4mega65/blob/master/README.md">https://github.com/sy2002/gbc4mega65/blob/master/README.md</a></p><p>The Core can be downloaded here:</p><p><a href="https://files.mega65.org/?id=03b68172-d6ff-49f0-971e-15bea2c6ad9a">https://files.mega65.org/?id=03b68172-d6ff-49f0-971e-15bea2c6ad9a</a></p>

<![CDATA[
<p>The MEGA65 can also be turned into an arcade game machine. As many early arcade games rely on fast reaction times, an FPGA-based recreation is much more faithful than software emulation. Unfortunately, arcade games usually require a complete FPGA slot for a single game.</p><h2 id="important-details-about-arcade-games">Important Details about Arcade Games</h2>
<p>To recreate the game two parts are needed: An FPGA Core and image files for the ROMs. The Core is like a Core for a home computer and only has the “hardware” part of the machine. It still requires the actual software, which is a seperate file, even if the Core can only play one specific game. Arcade Game ROMs are available in many flavours on internet, but the Core usually requires a very specific format. You need to read the instructions per Core very carefully and follow them to the letter to create the correct files. This in some cases requires <em>Python</em> on your computer. Due to copyright and licensing reasons, there is no official archive where Cores and ROMs sre bundled ready to use.</p><p>Some Arcade Machine Cores support “DIP Switches”. This refers to the switches on the arcade board itself and these are shown on screen. <strong>Do not open the MEGA65 to change the DIP switches inside.</strong></p><p>The Cores on this page are sorted in reverse chronological order of Core release. The newest releases are on top, the oldest on the bottom. By this you can see if there is something new.</p><h1 id="cores-available-for-all-mega65">Cores Available for all MEGA65</h1>

<p>The MEGA65 was produced in several revisions that have slight internal hardware changes. Unfortunately this results in Cores needing specific versions based on your MEGA65 model.</p><h2 id="if-you-are-a-new-mega65-user">If you are a new MEGA65 user</h2>
<p>All recent MEGA65 computers are <strong>R6</strong> models, meaning it is the sixth revision of the hardware. If your MEGA65 was shipped to you in 2024 or later and if it has a serial number higher than 1000, you are in the <strong>R6</strong> group.
The bad news: Some Cores might not be fully adapted to the R6 model yet and can’t be installed.</p><h2 id="if-you-already-had-a-mega65-before-2024">If you already had a MEGA65 before 2024</h2>
<p>Most likely you do have a <strong>R3</strong> model (there are others but if you have on of these you definitely know what kind of machine you have). Currently every released Core is available for R3 models and should also be in the future. So, if a core is available in two versions, use the R3 version. Cores for other models can’t be installed.</p><h2 id="how-to-be-really-sure-about-your-mega65">How to be really sure about your MEGA65</h2>
<p>When you turn on the MEGA65 in the native MEGA65 core, press the <kbd>RESTORE</kbd> key for two seconds and enter the “freezer”. Now press the <kbd>HELP</kbd> key to enter the “Megainfo”. Your board revision will be shown on the screen as “MEGA65 MODEL”.
<img loading="lazy" src="megainfo.jpg" data-is-external-image="true"></p><h2 id="how-to-find-the-correct-core-files">How to find the correct Core files</h2>
<p>Most alternative Cores come in a .ZIP file that contains specific files for the board revisions and have <strong>R3</strong> or <strong>R6</strong> in the filename. Just pick the right one. Some cores even have specific versions for other Rx models.</p><h2 id="can-i-damage-my-mega65-with-a-wrong-core">Can I damage my MEGA65 with a wrong core?</h2>
<p>With all known Cores it is not possible to install them when they are not the correct version. You will get a “Core hardware model mismatch!” error. Even if that mechanism fails, the Core should not damage the MEGA65. Make sure you do not install a Core into Slot 0, which has the fail-safe system to always install a correct Core into slots 1 to 7.

<p>The MEGA65 team welcomes any additional Cores. Fortunately for just about every retro home computer or video game console most of the work has already been done by the MiSTer community.</p><p>The <a href="https://github.com/MiSTer-devel/Wiki_MiSTer/wiki">MiSTer Project</a> currently is the world’s largest retro computing FPGA project. A full list of Cores already developed can be found here: <a href="https://github.com/MiSTer-devel/Wiki_MiSTer/wiki/Cores">MiSTer’s list of cores</a>.</p><p>So, there is a lot of interesting projects not only for MEGA65 enthusiasts but also for students and professional developers. Porting a MiSTer core is a great start to learn FPGA computing. Many of the Cores for the MEGA65 started out as MiSTer projects, like the C64 and Game Boy Cores.</p><p>To make your life easier, the <a href="https://github.com/sy2002/MiSTer2MEGA65">MiSTer2MEGA65 Framework</a> simplifies porting MiSTer cores to the MEGA65 by doing a lot of the hard work of adapting to a new hardware platform.
The <a href="https://github.com/sy2002/MiSTer2MEGA65/wiki">MiSTer2MEGA65 Wiki</a> offers a tutorial and all the information you need to successfully contribute to MEGA65’s growing library of cores. </p><p>Last but not least there is a friendly MEGA65 community on Discord. If you are new to porting Cores or to FPGA development in general, don’t hesitate to join our <a href="https://discord.com/channels/719326990221574164/1057791653517209601">#learn-fpga-dev channel on Discord</a>.</p>

<p>If you hate reading, watch this <a href="https://youtu.be/6ZcUFY77o3A">great video tutorial on YouTube</a> from Oliver Graf.</p><ul>
<li>Turn the MEGA65 off.</li>
<li>Copy the <code>.cor</code> file for your Model of the MEGA65 on a Micro-SD card and insert it into the MEGA65 (either internal or external slot).</li>
<li>Press and hold the <kbd>NO SCROLL</kbd> key in the top row at position 5.</li>
<li>Turn on your MEGA65.</li>
<li>You should now see a list of 8 slots, numbered 0 to 7. You can install a Core into any of these, but it is recommended to keep Slot 1 for the MEGA65 core. You can simply overwrite the contents of any slot with new versions or different Cores.</li>
<li>Press the <kbd>CTRL</kbd> key and the number of the slot you want to install to.</li>
<li>Select the <code>.cor</code> file for the Core on your Micro-SD-Card and confirm installation.</li>
<li>Do not reset or turn off the MEGA65 for the next minute or two until you see a confirmation message on screen.</li>
</ul>
<p>More info can be found in the MEGA65 welcome guide posted here:

<h2 id="what-are-alternative-mega65-cores">What are “alternative” MEGA65 cores?</h2>
<p>From day one, the <a href="https://mega65.org/">MEGA65</a> was designed to be the spiritual successor of the legendary Commodore 65. To realize that goal and stay future proof, the MEGA65 is based on something called a FPGA - “Field-programmable Gate Array”. Think of it as “programmable hardware”. Usually the CPU inside a computer is pure hardware: It is manufactured and can’t be changed by a user. An FPGA can be (within technical limits) any CPU you imagine and so can, like a chamelon, literally become a C64, Arcade Machine or Gameboy.</p><p>This is not what people usually refer to as <strong>emulation</strong>. An Emulator is a program that runs on a CPU and translates each command into instructions the CPU can understand. It’s like have a translator at your side when you do not speak the language. An FPGA runs the code as if it IS that CPU. The analogy is that you learn the language yourself and can speak it like your mothers tongue.</p><img loading="lazy" src="retrodesktop.png" data-is-external-image="true">
<p>Recreation of retro hardware via FPGA is not perfect. While most of the weirdest details can be identical to a real machine, there still are some obscure effects that might have fallen through the cracks. Still, because the timing of all the components in the FPGA is much closer to the real thing than in emulation, you usually get an extremly high fidelity.</p><p>So, an “Alternative” Core is basically a new language for the FPGA inside the MEGA65. It turns it into a different system. The MEGA65 has seven “slots” so you can immediately switch between them, and you can reprogram those slots with any of the Cores seen on these pages.</p><p>Oliver Graf aka <em>lydon</em> made a <a href="https://youtu.be/9Ib7z64z9N4">great YouTube explanation video</a> about recreating retro systems using FPGAs,
about the awesome MiSTer project and about the difference between MiSTer and the equally awesome MEGA65. Watch the video before reading on here, as it will provide you with valuable context.</p><h2 id="can-i-run-other-fpga-based-cores-on-mega65">Can I run other FPGA-based Cores on MEGA65?</h2>
<p>Unfortunately you can not take FPGA Cores written for MiSTer or the Analogue Pocket and run them straight on the MEGA65, but it is possible to convert Cores written for other systems. Please refer to the page <a href="creating-new-cores-for-mega65.html">Creating new Cores</a> for more details.</p><h2 id="i-have-additional-questions">I have additional questions!</h2>
<p>The best place to discuss is the MEGA65 Discord and the specific channel for Alternate Cores, which can be found here:</p><p><a href="https://discord.com/channels/719326990221574164/1177364456896999485">https://discord.com/channels/719326990221574164/1177364456896999485</a></p><p>Additionally you can try the MEGA65 discussion board here (mainly in German language):</p><p><a href="https://www.forum64.de/index.php?board/457-mega65/">https://www.forum64.de/index.php?board/457-mega65/</a></p><h2 id="can-i-add-a-core-to-this-list">Can I add a core to this list?</h2>
<p>I am checking the MEGA65 filehost regularly for Core updates and try to update this list within a matter of days, if not hours. If for any reason I have missed an update or you have a release that is not available on the file host, write me an E-Mail to <a href="mailto:boris@dreisechzig.net">boris@dreisechzig.net</a>. Updates on Work-in-Progress are also very welcome.</p><h2 id="where-are-the-cores">Where are the cores?</h2>
