  • Ever wonder how the Game Genie was able to perform its magic? It's all explained right here.
    Correction: At 7:40 the 68000 is referred to as a Reduced Instruction Set Computing (RISC) architecture, but it really should still be considered Complex (CISC). Its architecture is very similar to MIPS which /is/ a RISC system, but the 68000's instructions are still more specialized and can be a variable length. The idea of substituting in 16 bits at a time is still valid though since the instructions tend to be much longer than that of the other systems'. You can take a look at the 68000's instruction set here if you are curious: www.nxp.com/docs/en/reference-...

    What I always wanted to know is:
    How did it work on an NES without physically being able to push the cartridge down in? If you just have an NES game, and you push it in but not down, it absolutely won't play. The game genie made that connection not only possible, but sometimes IMPROVED as a connection. Many were the times I would not even put in a code, but just connect the Game Genie in order to get a stubborn game to work. It was very stable.

      Still, you'd need quite the programing knowledge to be able to read the memory on any of those consoles, read the assembly code and and make any sense out of it.
      I dont think "making it magical" would stop anyone with that knowledge as they could just as will read how the game genie decoded the codes and then make their own encoder and beyond that point its as if there was no magical code at all.
      It was either marketing retardedness, or someone was actually retarded.
      I can think of quite an easy way to make the required equipment for that with a few chips, and a 486 PC with DOS, and it should be able to dump the ram, the rom do single instructions and all, and all with things available in the early 90s and your could probably hook it into any console

      Start with the language C and the reverse engineer little programs you make in assembly (it'll probably be x86_64) the cpu's
      instruction set and stack protection will be different (they didn't have stack protection then or not in the same sense as today) but the concept will be the same. As it is for all devices from cell phones, routers, smart tvs, the apple 1, every video game console ever invented and 99.9% of all devices with a processor period. If you would like to know more on the subject just Google information on x86_64 assembly. It will be pretty hard to understand at first which is why I recommend starting with C and then going down to asm. If you already have a grasp on programming especially complied and not interpreted programming then you may be able to switch to just learning asm without a ton of difficulty but it's so close to the actual hardware it's not very easy for a human to read it. At all. But it is possible and many of us do. I develop buffer overflows and rce's which requires me to know assembly (for the modern desktop computer aka mainly x86_64). The entire reason I watched this video was because it was in my recommendations and I wanted to see if my hypothesis on it was correct. It was close, not entirely I didn't know they had any sort of changing of addresses back then. Hopefully this helps.

      @@n111254789 The code that is stored on the cartridge chips in Nintendo games is read-only to prevent corruption, so I don't know how even the game genie is able to skirt around this. If this were possible by any means, then a person could easily make unlimited changes to the game using a computer if they can transfer ROM files onto a computer from a game cartridge because this allows you to make changes to the code. I don't know how anyone could get the cartridge contents onto a computer though without using an illegal emulator, especially back in the days before computers were mainstream. But if you can then you could change what happens in the game without the limits imposed by game genie. I assume that you could even possibly run the game on a computer too using C or C++ platform which is probably how people on youtube create TAS content.

      @spritemeister 5 ปีที่แล้ว +29

      @@wrestlerx8494 The Game Genie skirts around the "read-only" limitation because it does not attempt to write to the cartridge. It intercepts the data signals between the cart and console and sends its own signals based on the codes that the player put in.
      As an aside, there is no such thing as "illegal emulation"; it's the ROMs that are protected under copyright, not the console BIOS, and even then you are allowed to make a backup copy of the ROM as long as you don't distribute it to others. (There may be other caveats, though. I'm no legal expert.)

    • @wrestlerx8494
      @wrestlerx8494 5 ปีที่แล้ว +1

      @@spritemeister SpriteMeister OK I did not know that it was legal to use an emulator even if you were just copying the game for yourself. There is an article on Wikipedia that talks about emulators that were used to write the ROM source code for cartridge-based games such as SNES games onto a computer, then the code could be used to reproduce the game and make copies. But these emulators were said to be illegal to own or use, and in fact with the game cube the game disks were purposely made in such a way that a computer disk drive could not read them to prevent piracy. This seems to suggest that they didn't want anyone to copy games even just to use without the intent to distribute them.
      Another thing is that most early games (NES, SNES) did not have stack protection in the source code at the time they were made since it was not used then. I don't know if this would affect the ability to "rewrite" the game using a modern version of C/C++, but chances are that any ROM code that you get from an original cartridge using an emulator might not run in a modern version of C. I know that there is a website with open source code for the NES version of SMB and you can run the code in C, but I have not tried doing this and I don't know if it works. I do know that the code can be used for TAS speed runs, as this was explained in another video.

    RISC vs CISC doesn't refer to the format of the machine code, but the way in which the instruction set is designed to access and work with data. A RISC architecture is almost synonymous with the load-store paradigm, where memory must be accessed as either reads or writes with a register, whereas CISC is known for having an abundance of addressing modes, many times applying to the same fundamental operation. Furthermore, RISC machine code can have variable-length instructions, such as the V810 used in the Virtual Boy.

    • @wrestlerx8494
      @wrestlerx8494 5 ปีที่แล้ว

      The funny thing is that you can do everything that game genie can do and more by using an emulator to write the game onto a CPU, or get the game's source code and run it with the program that was used to write the original game. You can then make changes to the code so that different things happen in the game just like game genie and run it on a computer. But that is basically all game genie is. It is just tweaking the game's source code so that something different will happen, albeit without your typical CPU. But you may as well say that the system itself is the CPU.

    Even as a kid I had a fairly decent idea of how this thing worked. I knew it couldn’t have just been pre-programmed with codes since the code book actually *encouraged* experimentation and a lot of those experiments did horrible, eldritch things to the game. I even picked up patterns in, e.g. infinite lives codes after a while w.r.t. which letters give you how many lives. So that just made it more fascinating to me as I was amazed the thing could somehow hit the same data with the same exact code every time.

      Yeah, the difference is not really about RISC or CISC at all. It's just that the Z80 and 6502 used by most early consoles were very simple 8-bit microprocessors (and thus cheap enough to go in those early consoles and home computers), and had very short, often 8-bit instructions. The 68000, on the other hand, was a more complex 32-bit architecture that typically had much larger instructions as a result.

    • @IsoFrieze
      @IsoFrieze 6 ปีที่แล้ว +9

      Ah, I made a mistake. From the few examples I looked at the architecture looked similar to MIPS, which I am familiar with being RISC. I see now that there are many instructions that can be several 16-bit words long.

    • @donpalmera
      @donpalmera 6 ปีที่แล้ว +2

      I think it was just a brain fart to be honest. :)
      The 68000 can do more than an 8 bit, has longer operands etc so you need to mess with more data. I think a RISC machine would be a different problem though. You would need to mess with more instructions because the amount of work per instruction is less.

      The 68000 may be considered CISC, but in truth it's more in the middle between the extremes that genuinely belong under the CISC and RISC labels. Although the 8086 itself wasn't quite as much of a CISC CPU as its current descendants are, the 68000 has a far simpler and more straightforward ISA. 68000 was chosen for Genesis and Apple's Macintosh and Lisa because of its simplicity and power, while Nintendo chose the 65816 for the SNES mostly because it is backward compatible with the 6502 (and, in terms of code execution, was very fast in its day).

      The original 68000 at least has many instructions that do multiple memory accesses and take multiple cycles to execute and other than the weird pre-fetch thing they aren't pipelined. I'd say that puts it right in the CISC camp.

And you never show us how to do a Game Boy/Gear code without a conditional check, though it would be pretty easy to remove the bits for that from the code, and presumably the rest would map the same way.
    Also, a lot of people seem to complain that you get technical too fast, and skip over explaining the basis of ROM and RAM to make everything else make sense. I don’t have a problem with it, but that’s because I already have a good grasp of it, so I can’t be the judge of that.

    Great video! The only thing I would add, for those too young to remember or who have never encountered a Game Genie, you didn't have to know any of this to just sit down and type in random codes to see what they did! I'm sure most people watching an explanation video already knew this, but mentioning it just in case.

If you want different things to happen in the game, then all you have to do is change the code. For example you can change the code for goombas to a different set so that they don't appear in the game. This is mostly a trial and error process, as you have to determine what set of code controls the goombas and how to change it to eliminate them, but once you make the distinction it should be relatively easy.

    What's interesting, is that you can probably make a modern version of this, which doesn't sound very interesting at first, seeing as we have modern day mods, except that the game genie is essentially just a piece of hardware, and can make huge changes to the entire system, they're of course less useful back then when everything was stored on ROM, but now that lots of things are stored on RAM, you could probably do some really interesting things, as it would essentially be getting around some of the safety measures put in place by Windows. The way you'd make it is through the fact that you can plug in RAM extensions. If you had something to plug in that would do what the Game genie did, it could be very interesting. Of course, it'd also be less of a fun thing you can mess around with, since it could likely break the entire system due to everything being stored on RAM.

    would be intresting to see a video (eventually) on the Gameshark/Action Replay. but given how long console generations it pasted barring into the Wii(then PS3/Xbox era) it still leave s a broad range of platforms and versions overall to cover. would be intresting to dig thru if theres any unintended side effects of using Say the gameshark/Action replay for PS2 *on a Backwards Compatible* PS3 (its possible but you haveto modify the system that gives you access to the Disc Drive and Swap, since theres only simple disc ID checks that prevent them from launching on said models at insertion time. incidently, the PS3 doesnt verify on *disc boot* what's in the drive be for all 3 platform disc types, again only at insertion time. a flaw that persisted since the PS1, and fixed with the 4 and presumably the 5 as theres no way at the time to dump a 1:1 copy of PS5 discs and burn them to check.)

  • @MrTableDesk
    @MrTableDesk 3 ปีที่แล้ว

    Not that it really matters but the 68000 Processor family aren't RISC processors, they're CISC processors. I understand why, given your reasoning you believe it is though. The main giveaway is that instructions for the 68k have multiple addressing modes, and can work with differing word sizes.
    So for example if you want to add two numbers, your source can be either a data register, or it could be a memory address, or it could be a direct number, or even an address in the address register ; it's been a while, but I think the destination has to be either a memory address, a data register, or a memory register. Anyways, depending on which modes and the word sizes used you use your resulting instruction could be 1-3 words long (resulting in 1-3 cycles).
    One of the main factors or RISC is that every instruction must execute in a single cycle, so for example add instructions would have to be register to register, since you only need a couple bits to address them. Also the whole multiple modes for an instruction type goes against the whole reducing instructions philosophy.
    The reason the 6502 op codes are the way they are is because they've got an 8 bit data width, but a 16 bit address width. I don't know if that'd make it RISC or CISC; I dont know if that was really a consideration at that point.
    Anyways, none of this really detracts from your great video, it's just not often I get to talk about assembly and machine code. The 68k family just happens to be the one processor I've written a lot of code for in school.
