About Memory

Memory is a huge part of how a computer or a gaming console operates. This blog post is my attempt to introduce to you how memory works and what kinds of memory is involved in different gaming devices. So there is basically some temporary memory that doesn’t store so much information. There is also larger memory that stores a lot of information but it isn’t used as frequently. There is also memory that has to be stored for a long time and memory that is used only for a short period of time.

This is basically how computer like systems work. They save data to memory, take user or some other input and make calculations depending on the data that they work with. They present something depending on what the user is doing. This creates the interactive part in video games.

Hard drives are the part of a gaming device that store everything that the game needs. A big part of this is saved games data. Some retro gaming consoles don’t have a hard drive. Hard drives were introduced to game consoles as Xbox was released. With for example the first PlayStation you had to get yourself an external memory card to save your game. Hard disks also store the data even if you turn off your game console.

Today it is common to have hard disks as large as 2 TB. The amount of space on hard disks has been increasing all the time. I remember a time when I bought a hard drive for my PC that had 15 GB. That PC had a 400 MHz processor. As you can figure the technology and performance of computers is advancing all the time. The data that is moving inside devices and also in different kinds of networks is getting larger. Also the size is getting smaller and you definitely can play games with handheld devices and also with your smart phone.

If you would like to get to know more about how computers operate I suggest you pick up a book about how micro processors work. I have some knowledge but I understand that my information isn’t so precise. So if you really want to dive in this topic just make a search in your favorite search engine and type in something like “micro processors free e-book pdf” or something like that. I know that there are many free resources for you to read.

 

Redream – A Dreamcast Emulator

Segas last gaming console, Dreamcast, was released in 1999, at least in Europe. It was actually released in November 1998 in Japan. It wasn’t a bad console. Many say it was the best gaming console that was ever released. To some it was even better than the first PlayStation. It sure was more powerful. It had many great games but it only stayed available for consumers to buy for a short period of time. Dreamcast was drawn from manufacture at the end of 2001. So there might have been more games released for this system if it would have been longer in the markets.

Some good Dreamcast games that I’ve played are Skies of Arcadia, NBA 2K2 and Crazy Taxi. I have heard that games like Sonic Adventure, Legacy of Kain: Soul Reaver, Quake III Arena and Jet Set Radio are good games also. If you have a game for Dreamcast I haven’t mentioned here feel free to comment this post. Skies of Arcadia is a nice role playing game. It reminds a lot of Final Fantasy games. Crazy Taxi is a kind of a driving game where you pick up customers and drive them where they want to go. NBA2K2 is pretty much what the title says – a basketball game.

Let’s talk about Redream. It is a Dreamcast emulator. It is available for Linux, Windows and Mac. There is also an option for a download for Raspberry Pi. The setup is made easy for a user of a computer. You select the download that corresponds to your operating system. Then you unpack and just run the application. You might want to add shortcut to desktop also. The user interface is also easy to learn. You can see all the games you have currently. You can select the location of your rom files inside your computer. You can also adjust some settings concerning your saved games, input devices, video (for example the resolution of the screen you are using) and some other options related to localization.

Redream is a good looking Dreamcast emulator. It’s clearly the easiest one to use when I think about its competitors such as DEmul and NullDC. They required more fiddling with the settings. Dreamcast emulators, all in all, are far more easier to setup than a well known PS2 emulator PCSX2 is. Don’t get me wrong. PCSX2 is a great emulator. It just is a bit hard for a non technical user to setup. Redream also works very nicely. I haven’t had any problems. It hasn’t crashed at all as I have used it for some time now. You can download stable release or development release. This means that the stable version has been tested and development version is the most recent versio´n that has the most recent new features.
