Hi, and welcome to one more episode of the 8-Bit Guy.In past episodes we have examined floppy circles and tape games.Furthermore today, we will discuss cartridge games!The absolute first games were dispersed on cartridge design for the Fairchild Channel-F, and soon after on the Atari 2600.ROM cartridges were utilized in a wide range of frameworks, like the Speak and Spell, melodic consoles,and surprisingly game frameworks as new as the Nintendo 64.I have likewise welcomed the Obsolete Geek to come over and show you a portion of his assortment.[OG] So, I love cartridges and cartridge based frameworks.Two or three my top choices, clearly the Neo Geo, an arcade based stage, which has totally enormous cartridges.Which could be somewhat precarious to connect.Additionally, another of my top choices, the turboGrafx, otherwise called the PC Engine in Japan, which has these truly cool charge card formed cartridges.Likewise extremely novel.[8BG] As a child with my Commodore VIC-20, I was fixated on attempting to duplicate a game cartridge to tape.I accepted that the game was some way or another stacked into the PC's memory similar as a game would be from plate.Also I had seen that assuming I took out the cartridge game while the PC was on,more often than not it would secure.

I saw that every so often when I'd haul the cartridge out, the PC would get back to a READY brief.Thus then I would endeavor to save the game to a tape.Obviously, it won't ever work.Furthermore the fundamental explanation it didn't work is because of my total mis-comprehension of how these games worked.So the 6502 processor could get to 64k of memory.Thus, for these models I will speak generally about the Commodore VIC-20, in light of the fact that it has a straightforward memory map that is truly straightforward.So you may envision the memory map looking something like this.Remember there are two kinds of PC memory: RAM known as Random Access Memory,what's more obviously, ROM, known as Read Only Memory.Along these lines, the VIC-20 just had 5K of RAM, and consequently the memory map looked more like this.So the Kernel and BASIC ROM were at the highest point of the memory map and the 5K RAM was at the base.There was a ton of void space where assuming the processor attempted to peruse and keep in touch with that region, there was just nothing there.So when you embed a cartridge, it in a real sense adds this extra memory into the fundamental memory guide of the PC, adding to the aggregate sum of memory in the framework.For this situation a 8K game cartridge is adding read-just memory, however you can likewise add an 8K memory extension cartridge which will add RAM to the machine all things being equal.A few cartridges even had 16K of ROM or RAM.In any case, when the cartridge is taken out, the data is at this point not apparent to the CPU, consequently why I was always unable to save those troublesome game cartridges to a tape or circle as a child.Presently on a cutting edge PC, a large portion of us know about what it resembles to add some RAM extension.Be that as it may, beside the BIOS chip, current PCs truly don't have any ROM chips or ROM attachments,since they basically anticipate that all software should be stacked from one or the other plate or USB or something to that effect like that.So despite the fact that the VIC-20 has 5K of RAM, it truly can use around 3.5K on the grounds that the remainder of that memory is utilized for screen memory and some other portion capacities.So assuming you load a game from tape or circle, the greatest size of that game will be restricted to around 3.5K. What's more these kind of games stacked into the VIC were normally amazingly crude games.Be that as it may, a cartridge game can be just about as much as 16K.Thus the games can be extensively more intricate, with more designs, and so on So on account of the VIC-20, cartridge games were typically better.[Ms. Pacman music playing]So that is the Commodore VIC 20, yet a couple of years after the fact the Commodore 64 came out with 64K of RAM and this switched things around a little.A cartridge in the C64 is as yet restricted to 16K.Also the games that were on these cartridges weren't neccessarily awful, however they were restricted generally to the exemplary sort arcade games.Yet, when you load a game from circle, unexpectedly you can utilize practically all of the machine's 64K which implies the games become much more rich and complex.The first Atari PCs recount a comparative story.The 400 and 800 both delivered with 8K of RAM, so by far most of games were delivered on cartridge.These frameworks were planned with the opening on top similar as a game control center, which propose they expected most games would be on cartridge.So curiously, the Atari 800 really has two cartridge spaces, one of them is marked left cartridge and the other is marked right cartridge.Presently, each of the cartridges I have are really they say "left cartridge" right on the ROM cartridge.Presently, I don't believe that the right cartridge was at any point truly utilized for a lot, indeed they disposed of it on every one of the later models of Atari.Yet, I think the thought was, back right now the machines had 16K of RAM thus I think they were believing that you could stack like an essential cartridge in one attachment and the other attachment could be utilized as some sort of expansion.Suppose for instance you had some sort of music or craftsmanship program or something, you
