As retro gamers, we all know the yearning to be able to play through a grand history of games from a variety of systems, but having to deal with the struggle of not only owning and maintaining an array of vintage hardware, but also having them constantly hooked up to our displays and audio systems.
As more systems and the games themselves! Many of us have been playing around with classic game emulators and ROMs for quite a while and a few years back, the Raspberry Pi scene did quite a lot to re-ignite strong interest the emulation environment. However, the most discerning retro gamers are increasingly looking at the world of FPGA for opportunities to bring the conveniences of emulation to a hardware that is closer to original console hardware.
For those that are relatively content with their emulation setups and the flexibility it gives them, it may be easy to question what the big deal is with FPGA setups. The short answer is that FPGA is programmable hardware that, when utilized well, typically provides a more accurate and efficient replication of the original hardware compared to software emulation.
I talked to him about his perspective on FPGAs and how he would explain their powers. He shared a more involved, but eloquent explanation:. Electronic PCBs [from original gaming hardware] are chock full of different chips and circuits operating in tandem at extremely precise timings. You can even feed controller and serial inputs directly to the FPGA for lag-free controls, or you can connect via USB which has an extremely fast polling rate and is always dropping.
So, little by little, MiSTer is evolving into the ultimate emulation platform, side-stepping the unknowns of a computer setup where controller polling rates vary, and where different processors and video cards yield vastly different results. That said, put a good FPGA implementation up against a traditional software emulator and you probably will feel a big difference between them when a core is done right.
So for those of us that are going to greater lengths and investments to enjoy a more idealized retro gaming experience, FPGA-based setups are very appealing.
There are currently still many limitations due to it being early in its development phase, but the possibilities are exciting. SmokeMonster explains this so well:.
Verilog and VHDL are hardware description languages that were originally designed to document chips both for manufacture and research. They could describe a single chip or an entire system. For example, if you have a Neo Geo custom IC documented perfectly in Verilog, you can send that off to factory and produce the actual chip.
But that is the ultimate goal of any core, even though it could take a decade or more of open-source contributions and research to get there. When all of the original hardware and custom chips have died, FPGA recreations can be used to emulate or even produce physical replacements…. Breakthroughs like a cycle-accurate Motorola X give any system based on that CPU a huge head start, and as more and more chips and circuits become available, more complex systems will become easier to port.
The talented team at Analogue helped shine the spotlight on the concept of FPGA for many retro gamers. The company started by creating modern consoles that used the guts of classic Nintendo and SNK machines. However, since it was announced in the era of Analogue, Polymega let down many enthusiasts when it was revealed that the console was going to run pure software emulation instead of utilizing FPGA.
Many retro fans were considering it a worthwhile investment to buy different game modules to support cartridge and controller formats for different consoles which is still pretty cool! While FPGAs are just the building blocks of a full console system, the MiSTer project is an organized project to allow people to build their own hardware emulation consoles or other customized gaming hardware setups while supporting many different vintage gaming and personal computer platforms.
Colin from MiSTerAddons. The soft cores are sometimes common between multiple cores, so their FPGA representation can be easily ported between cores. This helps speed up development of systems with similar architecture. The menu and main MiSTer code is overseen by Sorgelig , who has also designed most of the current add-on boards. And while software emulators have been fairly solid for these two platforms for a while, there is still a reason why many gamers still want to play their interesting game libraries on original hardware.
However, with these two hardware platforms not being in abundant supply and not even especially inexpensive in their original retail presence , they are prime candidates to have solid FPGA-based alternatives. While the Neo-Geo will take a bit longer to get to the same support level, it is currently under development and is showing promising signs. It's ultra-sharp. The MSX core is a great example.
It supports two virtual hard drives up to 2GB each, where the original hardware was limited to a few megabytes or something. SmokeMonster, has put together some PC core packs to help make the setup and experience more enjoyable for us mere mortals. Rather, an Everdrive -style menu allows the user to select and load the game.
In my conversations with him, SmokeMonster shared,. I am at heart an arcade and console gamer, but MiSTer has drawn me back in to the computer gaming world of my childhood. Although I am just now discovering the wonders of Amiga, and that has been astonishing. Much like the Raspberry Pi before it, the MiSTer is well-suited to be embedded in a handful of form factors — either custom-made or fit into other existing cases. Witchmaster from Atari Forum shared his stunning PC keyboard case hand made from solid teak.
See more photos and details. It will be interesting to see what other fascinating creations enthusiasts will come up with over the next few years. Sprites are also handled differently. Reset both for example and see how MAME shows junk sprites.
The Palette is also handled differently. If you play on an [CRT], you get the same delay as with the real arcade board. I look forward to the day where the machine is a dedicated appliance, not a Windows computer in need of a full desktop GUI and maintenance. Personally, as cool as arcade cabinets are, I would really like to see a console-like experience come to an Arcade MiSTer setup. Not all of us have the space or the cash to invest in a full blown cabinet.
And sometimes, even if you have a cabinet, its still nice to be able to lounge on the couch and play some arcade classics on a TV — with either a gamepad maybe even wireless or a full-blown Joystick. Those are all fine solutions — especially during this early, evolutionary phase of the project.
However, eventually, I think most of us would like to be able to either have some ways of having a MiSTer FPGA setup that feels more like a real game console.
This board will be the footprint of the DENano but will have controllers plugged in. When sitting on a sofa, with a long cord plugged in, the DENano will be sliding all over the shelf. One of my favorite features of the SuperNT, is the grippy, solid, case that stays put and feels premium.
One of the things that could really make a future MiSTer setup apart is the ability to add cartridge slots so we could play all our original games cartridge media on the machines. And Polymega has plans to have an elegant but somewhat pricey way of having interchangeable cartridge slot and controller port units for its software-based emulation console.
Perhaps we will see some large 3D printed cases to incorporate cartridge slot modules or we will have to see with little cartridge slot add-ons that are just plugged in via USB.
When asked if he foresees selling completed ready-to-go systems, he replied,. The reaction has been thus far positive, as customers receive an essentially plug-and-play device. The main software, and cores are pre-installed on the micro SD card. Of course, when you have a gaming machine that supports a handful of different platforms, you want a controller setup that balances universal support and flexibility. There are so many USB controller options out there, so we will share a few recommendations to help you out.
There are actually two projects can help MiSTer fans utilize the classic controllers they love. However, the Bliss-Box 4 Play is solid solution for using original controllers. Revisiting the topic above of Console-Like Presentation , both the LL Cool Joy and the BlissBox Bridge will get us closer to having that streamlined presentation while also giving gamers total flexibility and increased authenticity of using original console controllers.
This interview format should be interesting for those that are intrigued by the topic and would like to learn more of the technical background of the project.
So essentially you get any controller on any console. Though the magic in communication is where things get interesting. Bliss-Box had to come up with a way to communicate from the 4-Play to the Bridge in a fast and reliable means without adding to the existing hardware.
The solution was simple. We designed a protocol that can be invoked by holding both USB pins high. Once the 4-play sees this signature it goes in to bridge mode and disables all USB communications. The bridge can now begin listing for commands. If you plug in a normal USB to a device holding the pins high, it does not communicate and an error shows on the bus. So, it is a perfect solution that can be turn on and off or switch from USB to Bridge mode via software.
The link between a 4-play in single mode or Gamer-Pro has a latency around. Shown in the image you can see the communication from the 4-play to the Bridge. So, when this concept was mentioned, kitrinx immediately had a thought. The idea was a low latency controller poll mechanism directly between the MiSTer and the Bliss-box. We will be able to align the poll rate to the core and be sure the data are ready.
This does not mean we will not still pursue the board but it does attract the Bliss-Box to the MiSTer quite nicely. Kitrinx had this to say in regards to that. These devices are nearly impossible to replace with modern alternatives, necessitating an adapter to use the original controllers with MiSTer. Purchasing individual classic controller to USB adapters for all of these controllers could become quite expensive. As such, it is an outstanding value even used via USB if one wants to use a lot of these unusual original controllers with the system, or even just more standard SNES and Genesis type controllers.
With all the power that passing the IO through the linux side of MiSTer brings to the platform, it does have one drawback: It introduces an average about 9 to 18ms of latency, according to my oscilloscope. The majority of controllers fell in the 8ms range, with a cheap Chinese one having over a frame of lag. The core can then sync its controller polling directly, and clock in at under a millisecond of latency with most controllers, leading to a snappy, consistent input experience.
In addition, the API can report what type of controller is connected, allowing special peripherals such as Paddles and Light Guns to work more reliably. What do you think of the current MiSTer controller configurations and what would you improve if you could?
You can only use the first axes, so it is no good for many adapters out there in the way of paddles and other special configs. Again, the idea is not to use a driver and allow this to take place with the tools already available. To make a control transfer you just need to code it and talk via USB.
It also allows any code to talk directly to the controller and receive data back, essentially, tunneling via USB. Will the MiSTer take advantage of these things?
