How Oldschool ROM Cartridge Games Worked

[@GodzillaGoesGaga]

I designed the development cartridge for Sega Genesis. It was called the RamCart and used static memory to hold the cartridge image. Data was written to it by access to a couple of phantom registers. Once the final image was confirmed, that image was used in the ROMs for production. I worked on a lot of the early 8 bit and 16 bit games platforms.

[@graxjpg]

Anything a gen z’er would recognize? Besides the genesis, which I own

Probably not. Tech goes obsolete so quickly. This stuff was purely for game developers and not the general public.

Licensed NES cartridges all looked the same because Nintendo wouldn't let other companies manufacture them - they made the carts themselves, and shipped them in limited quantity to companies that ordered them. This was done to keep them from flooding the market with crappy games, which is what killed Atari in 1983. This is why some bigger game companies made games under multiple brand names (i.e. Konami and Ultra) - to get around the order size limitation and make more money selling more games by pretending to be separate companies.

[@scottythegreat1]

The multiple brand names were created to get around one rule Nintendo had back then, a publishing company could only distribute 5 games a year. That rule changed when game companies cold make their games for more than one console that actually threatened Nintendos position as market leader (ie. the Sega Genesis/Mega Drive).

Fun fact: The expansion sound on NES cartridges is still there; it's just there's no pin on the cartridge that connects to the speakers. There are ten unused pins on the cartridge that go to a port on the bottom of the console, and the expansion audio in such games is usually connected to pin number 5. There's a gadget you can plug in underneath the console to bridge the expansion audio into the NES's sound output.

[@PScoopYT]

For anyone who wonder why the Famicom that showed up in this video is different from the usual one we've seen, It's because THAT wasn't the original Famicom. It was a Twin Famicom which only released in Japan and can play both Famicom and Famicom Disk System games in one system. Also another point out is that only the Famicom Disk System have an additional sound chip. Since Twin Famicom contain both system you can hear an additional sound. However, I don't think any cartridge games used an additional sound chip because if you don't own a Twin Famicom, You can't use a cartridge games while using Disk System anyway. Only the Disk System games used an additional sound chip. Update : There are some Famicom games that had an additional sound chip! like Castlevania III for example.

[@bagelmaster8]

It was also not made by Nintendo, but by Sharp. And it came in two color variations.

Some Famicom carts did have an extra sound chip in, like Castlevania III as they showed. But yeah the disk system did also have extra audio functionality of its own.

[@abrandoncadabrandon6326]

I did similar experiments as a kid with my Playstation, but I remember removing a disk would not cause the game to stop unless you navigated a new menu or performed an action that required new content to be read from the disk. Helps explain a lot about how data from physical storage "lives" in computer memory (volatile memory)

[@stephensnell1379]

Only data in RAM is volatile memory whereas hard drives are permanent storage for data as it can retain data even with the power switched off and RAM will lose data completely without power

[@SatoshiMatrix1]

Minor correction to "For example all Nintendo [NES] cartridges look more or less exactly the same no matter of what company actually made them". In direct response to the American crash of 1984, all licensed NES games were manufactured solely by Nintendo [and later Konami due to preferential treatment]. This involved a process in which developers would submit their finished game code to Nintendo and then be forced to wait for Nintendo to manufacture the games. This is why all licensed NES games use the exact same gray cartridge shell and mix of pcb designs. Regardless of the developer, all NES games were produced by Nintendo [although later Konami game pcbs were produced by Konami themselves]. THis was NOT the case with the Famicom, the Japanese NES. in Japan, Famicom games were produced by the publisher, of which there were dozens and dozens. This is why Famicom games very greatly in size, shape and color, and what makes Famicom collecting so interesting. Virtually no two Famicom games look alike.

[@KairuHakubi]

licensed being the key word. i remember 'king of kings the early years' (a really good game actually. well, the camel one was good) had a different cartridge.

[@makomk]

Not only that, to ensure compliance the NES has a special lockout chip which checks for the presence of a similar chip in the cartridge and resets the system if the check fails.

[@jjjacer]

same with Tengen Vindicators, while mostly the same it had an angled end, i remember it was sorta weird trying to remove it from my old NES

[@dareelcatskull]

Notably, the Tengen games which were actually made by Atari, and were unlicensed and manufactured by Atari rather than Nintendo. Sega did something similar with the Genesis, but EA wanted to be able to manufacture their own cartridges so that's why all EA games on the system are taller and have that yellow tab.

[@marscaleb]

Bank switching on the NES was ridiculously effective. Games that employed that could switch banks so rapidly without error that said games could bank-switch in the middle of drawing a frame to extend the game's graphics. A simple example is the status bar in Super Mario Bros 3, which runs on a completely different set of tiles than the rest of the level. The animated tiles in that game were also animated via bank switching. And the way the NES enabled extending its capability through hardware on the cartridge was much different from other gaming consoles. As I understand it, part of the system's PPU was directly connected to the cartridge, and so instead of simply plugging in an array of memory, the cartridge is actually part of the rendering hardware. This allowed the system to have games that expand the capabilities far beyond the original specs than any of the later and more advanced consoles could.

[@lightfeather9953]

Yeah I was scratching my head for a moment when I saw a video of doom being ran on an NES using a raspberry pi inside a cartridge.

Back in the days when I considered myself a hacker with my Atari 800XL I was able to actually save an image of a ROM cartridge to disk. I wrote a small machine language program in the boot sector of a floppy drive which would stand by for a specific key press. The Atari 800XL was built in such a way that you could insert and remove cartridges without crashing the computer (if the cartridge was not running of course). If you were careful you could insert the cartridge and its content would just show up in their corresponding location in memory (always the same 16K block). My program would wait for the key press and dump a copy of the contents of that memory lock onto disk. Then I booted normally and recovered the image from that disk using another machine language program that would save it to a regular disk file.

I learned the trick for doing the same thing with a VIC-20 cartridge. You would cut a trace on the cartridge board and add an on-off switch. You turn the switch off before inserting the cartridge. Then you boot the VIC-20. The computer does not sense a cartridge so it boots to BASIC. Then you flip the switch to on. Now the computer can read the game ROM code. Then you could just write a bit of code in BASIC to copy the game code to floppy.

I heard the only reason we didn't get the VRC6 sound chip in the American release was because Nintendo of America didn't want expansion hardware in NES carts. It seems like they changed their tune by the time of SNES

[@mresturk9336]

@@knightshousegames It was a bit more complicated. The VRC6's sound channels used the same connection pins as the Famicom Disk System's added sound channel did. Problem was the American NES moved those connection pins to the expansion slot on the console's bottom to make it more streamlined (the FDS attached to the Famicom in a rather clunky manner). Thus even if they got Nintendo's blessing in order to fully port the VRC6 chip they would have had to figure out some way to reroute the sound channel's connectors to the bottom of the console. Probably decided it wasn't worth it just for one game (There were other VRC6/VRC7 games, but they were never ported outside Japan).

[@MonkeyPunchZPoker]

Tengen, a division of Atari, made their own cartridges. They frivolously sued Nintendo (I don't remember what for, and was probably a subsidiary) and the way the legal system at the time worked at the time Nintendo had to produce the source code for their DRM chip. Years later when Nintendo started getting stingy with their licenses (or maybe a cartridge shortage) Tengen decided to roll their own.

[@knightshousegames]

Nintendo was stingy with their licencing because they were extremely concerned about quality control. Companies were churning out dozens of games per year that were crappy reskins of similar games (think the mobile game market today), so Nintendo had to get picky to keep up their reputation. This was just after the console crash of 1985, so the industry was on really shaky footing at this point, so a reputation for quality was important.

If you look at the MSX systems, which often had 2 cartridge slots, where both slots were actually used. As cartridges not only were used for games, but also for extension hardware such as soundchips (OPL, OPLL, OPL4, SCC, etc), extra RAM, and even graphics chips (for instance V9990), or in rare cases copy-protection dongles, it isn't uncommon for both slots to be used by these extension cards, to be used by for instance disk-based games. Or, in the case of several Konami games, combining certain game cartridges, would enable hidden cheat modes, replace certain graphics, or even be required for the good ending. It wasn't just limited to 2 carts though; using a slot-expander, even more than 2 carts can be used at the same time. For instance combining 2-3 different sound chips with extra RAM, DOS 2.x support and a better graphics chip. Or, in more recent years, for flash-memory based storage such as CompactFlash or SD cards. :)

If the bus is properly pulled up (or down) and the first byte of cartridge address space is never 0x00 or 0xFF based on which way the bus is pulled to, the BASIC ROM can start with something like this (described using x86 assembler but you get the idea) cmpb rombase, $0 ; if pulled down, $0xff if pulled up jnz rombase

There are versions cracked to disk, but they have taken away animations or all audio to fit more into RAM.

[@jackschidt8711]

Some computers, like the tandy CoCo, used one set of contacts to sense a program or disk controller and auto execute the cart. If you taped over the specific contacts with a little cello tape, it would disable the auto execute. Then you could indeed save the memory addresses for the cartridge slot to a tape.

Pro Tip: the best way to clean the contacts in your cartridges is to use a simple pencil eraser. Just rub it up and down until the contact is shiny again.

[@AshtonCoolman]

It's interesting that we use cartridge consoles today. They're the portable Nintendo 3DS and its predecessors. The rumors are the Nintendo NX will use a small cartridge as well since we can fit 64+GB on one of them with faster access speeds than Blu-ray and most mechanical hard drives. CARTRIDGES RULE!!!

[@BodethIII]

Or, pretty much like SSDs on a PC or installed in a console. Both have no moving parts and instant access like the cartridges of old. the Nintendo NX potential cartridges may be special cheap small SSDs in a specific format.... like a cartridge.

[@temujin1234]

I wonder why this would be better than putting solid state memory on the device itself. If it's actual ROM you could go back to no loading times, but that sounds expensive.

[@kgoblin5084]

Modern ROM is significantly cheaper & better than it was back in the 1980s. The real reason the games console industry went to CDs was the storage issues at the time... There were quite a few JRPGS that never came over to the USA (or came over butchered) because it was literally impossible to fit the translated text into the cart. Ditto higher quality art & music assets. Cost wise, cartridges were marketing for the same ~$60 you would pay for a modern game. The real driver was the data storage issues.

[@sergiofls7623]

JohnnyNismo the rumors are true. the nintendo switch has a some kind of a "game card" or a cartridge.

[@treysandbothe3748]

While not my favourite to play, I absolutley adore retro consoles as historical pieces for tech and games in general. This channel is super cool!

[@PrekiFromPoland]

An interesting feature of MSX computers should have been mentioned here. Namely one can combine two cartridges for some special stuff or even advantages, kind of hardware cheat codes. Konami was known for prominently using this technique in their games. For example: inserting a Metal Gear cartridge alongside one containing a game called Usas will reduce received damage by half. Another interesting example is the original 1988 release of Snatcher, which had floppy disks with actual game data on them, and a cartridge containing Konami SCC sound extension chip.

[@wayneljm]

I remember renting a Genesis game and it wasn't the one inside, someone swapped the internals and that gave me a bad idea as a pre teen

[@EthanDoezYT]

I rlly liked this video, gave me a better understanding of how these kinds of games I used to play (and still do) worked.

[@Audiomancer]

I really enjoyed listening to him talk about trying to save cartridge data to tape:) I tried doing weird stuff like that with my c64 as a kid....none of it ever worked:)

[@SpamMeNotEver]

Audiomancer I saved my Omega Race cartridge on my C64 to disk. It loaded into memory just below the lower ROM bank. Just had to load it back into RAM and execute a SYS command to start it - small basic program did the trick.

[@MichaelClark-uw7ex]

There were snapshot programs for the C-64 that copied the entire memory onto the 1541 floppy so you could play cart games without the cart. I had one plus I hacked my Fastload cartridge and installed a warm reboot button, saved a lot of wear and tear when changing games.

[@bjbell52]

My first Atari came with a cassette player that was used to load software. It took a long time to load games because it was so slow. Eventually, some software companies took advantage of a memory location that controlled the speed and were able to cut the loading time down to almost half.

[@bjbell52]

I had a hacked Atari 800 which gave me a built in debugger. Cartridges were easy to copy to disk at first. Later cartridges had software protection schemes that would stop the copy from working. Thanks to my hacked Atari, I could single step through the copied cartridge, find the write protection scheme and remove it. Then I would save it back to disk. And no, I wasn't a pirate. I bought most of my stuff from work, since at the time I worked at a video store that also sold computer software - I got them at cost. I just wanted a backup in case I lost the cartridge.

[@foufoufun]

I've never seen that model of the NES. Did come before or after the red and white model?

[@Horzuhammer]

If you're refering to the original Famicom as the "red and white model", then later. The original was released in 1983, the machine in the vid is the Sharp Twin Famicom, which had the regular Famicom, plus Famicom Disk System built in. It came out in '86.

[@foufoufun]

Horzuhammer Ah I see, it is a two in one.

[@jaffaman99]

yeah, his statement is a little confusing, that is not the 'Japanese version of the NES' it's a special version of the famicom, made by Sharp, that had the disk system built in. On top of that it's a second revision of that system.....

[@foufoufun]

jaffaman99 The disk system was only release in Japan though? right?

[@Horzuhammer]

foufoufun0 Yeah, as was the Sharp machine.

[@TheFr0z3nF0x]

Love the robotron noise at the start of the video. That takes me back.

[@oldgoodrandomroutine]

6:53 Those are RAM slots, you could add up to 48k RAM, but then THEY removed it as memory became cheap so they all were released with 48k

[@ljelman6321]

wow I am am shocked You didn't know the Atari 800 could copy game cartridges!!!! You'd run a program in basic .So put the basic cart in left slot, then run a piece of software in basic. I had 2 disk drives so no problem there. Run the program and it would then ask you to insert game cart in the right slot. Obviously you even showed that inserting carts with power on can crash the system, after a couple tries in would not lockup and gave you back to basic and the copy program.Which then allowed the game you placed in the right slot to be copied to floppy disk. Its a tiny file. Many game carts could fit on just one floppy awesome for my BBS. Eventually Atari got wise to this practice and put some kind of protection on the carts. I specifically remember Joust would copy and play with no sound then crash.

[@sl9sl9]

@@John-ik2eg This method is legit, there was 3 ways to do it depending on the game, the media it came on (cart/disk/tape/etc), and the hardware of the console/computer: 1. Copiers that hid in video/screen memory. This was a brute force method that did not always work and was not popular; the copier code would hide itself in video memory using black text/pixels on a black background so you wouldn't see garbled stuff on screen. It could not hide in any other memory because most games filled up all memory space and would overwrite the copier when they loaded. ''Lerm Tape Copier'' is an example of this method. 2. Simple BASIC ''loaders'' that could be typed in individually or loaded from a collection on tape/disk. This was the most common method as it always worked for supported games and cost nothing. Gaming and computer magazines often printed these ''loaders'' for you to type in, they would load and decrypt the game then you could make a copy of it on tape/disk or hack the game code etc. Each loader was targeted against a specific DRM copy protection scheme, and would only load the game(s) which used that version. Many of these loaders were designed to hack the game to give infinite lives etc, being able to copy the game was a side effect of the loader decrypting it. 3. Hardware plug-ins such as the Multiface One or much more well known Action Replay. Again these were designed for cheating in games, but they also allowed you to pause the game and copy a memory image to disk/tape, effectively creating a pir8ed copy. A little similar to method #2 but MUCH easier and cost money. Many magazines printed ''POKES'' or Action Replay codes for use with these devices, little mini hacks that gave infinite lives etc by changing a memory address or two. Using an EPROM burner was an extreme method that almost nobody did, because these burners were incredibly expensive and far too technically difficult for most people. It required de-soldering the ROM chip out of the game cart to copy it, further adding complexity and expense. Very smart people who had access to EPROM burners are the reason we have ROM images of old cart and arcade games today for use in emulators, but back then there were much easier and cheaper methods to copy a game.

[@trollobite1629]

@@sl9sl9 "...eprom burner that almost nobody did..." Err, actually, that's exactly what nerds did, back in the 80s everyone was hand coding in machine code, hacking the hardware and disassembling the ROM for the mighty Z80

[@blucy10]

I had a heavily modified Atari 800. Behind the slots there were 3 spaces for ram cartridges. You could have as much as 48K in 3 Atari cartridges, and some manufacturers provided 48K on 1 cart. This was in addition to the cart slots. Inserting a rom cart would map that memory to areas that would have been in ram. There were ways to switch the power to the ram while mapping the rom, so you could copy the rom to memory. Some copy protection soon prevented this method. The right slot mapped into a lower memory as I recall (the highest memory was the system rom, which Atari provided source code for!). In the end I had a Frankenstein monster, with a switch for ram and rom and a cart which had some sort of copy protection break. Those were the days you could have a debugger running to examine a 16K cart, and know exactly how it accomplished its tasks. It helped to know a few of the developers too.

[@TheMamaluigi300]

Hopefully next episode is about CD-ROMs.

[@DiEvOrHeR]

same as floppy only a laser reads them.

[@BGBTech]

yeah. a CD is more like an optical version of a vinyl record than it is like a floppy (it is a single long spiral that the read-head aligns with and follows). though, CD's do have something in common with floppies in that they both organize their data into blocks/sectors (2kB on a CD, vs typically 512 bytes on a floppy). then there was Laserdisc, which effectively was using the disk as an optical version of a record (no data blocks or compressed digital video, just an analog composite A/V signal recorded directly to the disc).

[@BGBTech]

***** well, those came after DVD. Laserdisc basically predated CD's, and were about the same size as vinyl records and likewise usually stored in sleeves. they were not popular though because they were expensive and not recordable (unlike VHS). when audio CD's came along, they switched over to recording the signal as data. later on, VCD and DVD stored the video as compressed MPEG bitstreams.

[@KrotowX]

I guess, it will be episode about hexagonal and octagonal CD's :)

In fact we created multi-sided CD's just for fun from single CD's which had one 12 minutes long song and rest of space wasn't used. Both 6-sided and 8-sided shapes played well after cutting.

The Sharp Twin Famicom AN-505-BK was made by a collaboration between them with a licence from Nintendo to Sharp to manufacture... I think it is cool though, because it also contains the Nintendo Disk System, that was an add-on to the Nintendo's "Famicom"

What's really funny, cartridges are starting to make a comeback. The 3DS and Switch are both cartridge based. Although it should be noted that these cartridges are nothing at all like the ones from the 8/16-bit days. The ones of today are basically modified SD cards, which are a storage medium rather than a ROM cartridge. Back when CD's/DVD's/Blu-ray first came out they stored far more than you could on any non-optical media. Nowadays it's gone back the other way, there are SD cards that store 2TB.

[@todesziege]

While maybe not reaching the same size as a CD you *could* make huge cartridges - they would just cost hundreds of dollars like the Neo Geo games. And probably be physically huge, again like the Neo Geo games.

[@straightpipediesel]

That's Nintendo being cheap and stubborn. Mobile gaming is the last place you want to carry and swap tiny cards. You can keep a stack of games next to your home console fine.

[@GreyWolfLeaderTW]

"Game Systems as new as the Nintendo 64" Have to back-edit that, because the Nintendo Switch still uses ROM cartridges when it was released in 2017.

[@ondrejsedlak4935]

Not really. The Game Card for the Switch as it's known, actually uses flash RAM which is set to read only. ROM storage is a completely different technology, which did stop around the time of the N64 in terms of gaming consoles.

[@aa-au]

My first computer was the Tandy Color Computer which also took cartridges. I think I tried the same trick as you did, but I learnt quickly that the program was stored on the cartridge and not the computer itself. Best computer ever - I learnt so much on it.

[@KneelB4Bacon]

12:11 Wow. The worlds first plug in graphics card.

[@qwertzy121212]

Not by far. As one example, the IBM PC had interchangeable graphics cards in 1982.

[@Whelkman]

Even older: the Altair 8800, basically the first personal computer, shipped with a handful of LEDs to function as a "display". Later on MITS, the company behind the Altair, manufactured video cards.

[@Optimus6128]

Unless he means it was the first GPU in the sense of modern 3d accelerators, where the programmer just sends polygon data and it does the rendering for you. Which might yet not be the case. I used to think it was (because it is presented as a chipset for 3d and all games had the same flat polygon rendering). But I read somewhere that even the SuperFX is not GPU like, the programmer is not sending polygons. It's still a quite more powerful general purpose CPU where the programmer has to write his own software renderer to render polygons or any other thing he desires.

[@GGigabiteM]

+Optimus6128 >SuperFX is not GPU like, the programmer is not sending polygons. Correct, the SuperFX is more of a DSP than a GPU. It uses a custom RISC architecture tailored to primitive 3D and advanced 2D workloads, but the programmer is still responsible for creating the rendering engine that runs on it. Back in the bad old days, there was no off the shelf code libraries or engines, everything had to be made from scratch. This is why there was such a disparity in quality between games on a console. You needed a really skilled programmer to squeeze every last ounce of performance out of such limited hardware in those times.

[@Zantar16]

Do the DS & 3DS still use ROM cartridges?

[@CJRussell]

They are more like SD Cards per se, but, yes, they could be considered cartridges.

[@Zantar16]

***** I think the rom is still used to contain all the game data while flash ram is used to store game save data.

[@TylerSteven9]

It's still ROM although the insides are much different compared to the 80's and 90's ROM technology.

[@EwanMarshall]

yes there is addition of flash memory for saving data, and the bus it's on is a little different, but fundamentally it's the same in how it works. The difference between disk and memory is actually quite small basically it's just how it is addressed and on what bus you ask for the information on. We also do a lot of multiplexing and serialization these days so it's < 10 contacts rather than 20+ contacts.

[@claudiolluberes111]

+Ewan Marshall Doesn't the DS have internal storage? I think the era of saves in cartridges ended with the N64.
