Zelda 2 - Behind the Code

the lag in the music is somehow very nostalgic

[@ilikemyrealname]

The lag in dungeons in Zelda 1 gets me right in the feels, too

It oddly gives the world that much more of a bigger, epic feel. Like the NES is struggling to handle just how vast it is.

I agree.

[@masonwheeler6536]

That "level up softlock" is a _hardlock:_ a state at which the game has crashed or locked up and normal gameplay is unable to continue. A softlock is a state at which gameplay continues normally but the player is "stuck" and unable to progress due to an error in level design or data. For example, being stuck inside a solid object after warping from the fairy glitch would be a softlock.

You just count like normaly but until 16 for every tenth. So, for example if you try convert 2C: 1) separate is first - 20 and 0C 2) then convert - hex 20 = hex 10 and hex 10 = 16+16 = 32 ; hex 0C = 13 3) in summary 32+13 = 45 in dec Or you can just use calculator on PC and convert it easly.

I second this, best Zelda 2 video on youtube by far.

[@DoomRater]

Berserk Studio makes games with many nods to Zelda 2's mechanics, especially one of their earliest pieces Hero's Arms which feels like a "what if Zelda 3 had Zelda 2's mechanics on top of that?" experiment, and their latest game Infernax which feels like a Zelda 2 style game packaged into a horror game, also nodding at Dark Souls (because who doesn't at this point). You pretty much can't unsee the influence Zelda 2 had on either game once you play them for any length of time.

[@PlasticCogLiquid]

@@DoomRater Gunmetal Arcadia Zero is also a game that gets all its influence from Zelda II, it's good.

[@psmstr]

Zelda 2 is a brilliant game that was sadly marred by some really bad decisions. Things like how you lose all your EXP on game over, you can’t save whenever you want, no healing outside of towns and the Life spell, and to even get Life, you need to do a pixel hunt with no indication that you’re supposed to press A at a particular table in a particular house. But a lot of those problems are palatable now with save states and internet guides. Yeah, I’d be totally down for more Zelda 2 videos. Fantastic game.

[@MarkAltosaar]

I had a strange bugged cartridge of this. The game was unwinnable because the hammer would not spawn. My brother and I had no idea why we couldn't beat the game. We didn't even know what was missing. After bashing our heads against it for years, we'd experimented by creating our saves with various Zelda character names to see if there was something like a second quest, like the infamous skip in Zelda 1. My brother for some reason played through a game titled "IMPA" and ... lo & behold, the hammer spawned in Death Mountain! Further experimenting showed that just starting a character with the first letter in the name being "I" was enough to make the game work. Bizarre.

[@null_state]

I love stories like this. Alongside the mystery presented in this video as the "F Attack". I've found myself run into similar situations, notably weird warping in Zelda 3.

The counselor said “Did you call earlier today because you are the second person to call about this.” Thought it was a code my sister stumbled upon. She had it happen very early in the game. My mom and I were much farther along in our game, but had so much trouble with the Thunderbird boss we ended up using her file to beat the Thunderbird.

[@clonusmaximus4600]

I don’t think ppl understand the genius of Zelda II. Utilizing a TWO action button controller Nintendo was able to to devise a brilliant combat system. The high low attacks can be blocked by a shield with just the up and down buttons because Link’s shield is always on guard. Link can also attack with the same scheme. Other attack types are a combination of the two action buttons, jump and stab: down thrust, up thrust, etc. Theres also a surprising amount of subtlety to the optimal type of attacks per enemy. I could on. Fact that this game is so often scorned, even sometimes by the designers boggles my mind. Yes, it’s tough. But it’s also engaging and addictive because of its combat depth 30+ years later.

[@dudeinjapan]

Holy cow, wow, I got the attack value bug too as a kid, except "A" instead of "F". In the same save, the raft was missing from the normal place you get it (but also not in my inventory) so I couldn't progress the game. It's odd that there are many reports of attack value and missing items. Never experienced it in any other battery-backed NES game. Feel like there must be some additional factor here to explain why it happens.

@@EnchantedSmellyWolf As somebody that grew up during the release of this I can assure you that difficulty wasn't the biggest concern with the game. The major issues people had were that the series went from pretty much defining "free roam" to making your progression more linear. The grand feel of exploration that made Zelda so amazing, was greatly reduced. It was a big shock to those of us that were eagerly awaiting the sequel to a game that had broken so many barriers only to find that they dialed back most of what made it special in the first place. This second installment sold 2m less units compared to the first, and 3m less than the game that followed. A game that restored the large, accessible overworld that everybody loved.

Nice video - the level of detail you go into on memory locations is just the right amount to be interesting but not overkill. I recently built a NES FPGA (called Whirlwind), and though I knew 6502 beforehand, I learned a ton (obviously by necessity) about the NES PPU/APU/mappers/etc. And while I dove deep into debugging SMB while testing things out to troubleshoot hardware issues, I didn't jump into the source of many others games, so it's really cool to get a nice walkthrough of the mechanics behind many areas in CPU RAM in Zelda 2. Ironically enough, one of the few MMC1 games that didn't work correctly on my FPGA was Zelda 2, so this makes me want to dive back into debugging it to see why. Off to watch your other videos!

@@josephbrandenburg4373 Well, of course, this is an acheivement. But not as big as you might think. The real acheivement is managing that level of complexity on a system that has 2k of RAM, whatever the language that is used. Getting used to code in assembly takes some time, but, it's rather more accessible than you think. :P Suggestion, try the game "Shenzen I/O". Nowaday we compare the productivity of having things done to language like Python and C#. Yes, indeed, thinking about assembly seems like, daunting. Slicing a String in Python takes one line, in 6502 asm it would take at least 15 lines of code and of course wouldn't be as natural to use... However, you have to take in consideration that, in 1985, coding in ASM was pretty common, everybody developpers did it. Nobody would regard you as a weird freak, like today. It seems like an acheivement because we no longer know how to do it, but, any above average modern developper could get the perk in less than one month. Have a good day!

Some more questions about the Fairy Warp glitch: Why does doing it in a town cause you to be stuck in the ocean when you leave that town? As a more general question, if the special exit value of 3F returns you to the overworld from where you entered the scene, then how do scenes with 2 different overworld tile destinations (one if you leave on the left, one if you leave on the right) work?

Genuinely some amazing content. I expect your channel to grow heaps in the coming months.

Things that fascinate me about this game (and there are many...some that were in this video that I never knew I needed to know about) The XP penalty in the game for dying and getting a game over was that it set the players XP back to zero and forced the player to play from the start of the game and then walk all the way back to whereever they were where they died (which nowadays is akin to say a "Souls" game). I have wondered many times if they programmed the XP in this game to act more like a "score" vs. experience points but that might not be something that could be looked at In relation to the XP gain....what is the point in the code that: A: Gives the player a magic jar B: Gives the player a treasure bag C: Just the XP for the kill Moreover would there be a way to go into the editor to force the game to give the player the XP for killing an enemy that gives you just the magic jar (because if my memory serves it does not do that in the game as is) Also if I remember correctly in the early game if you kill a Goblin (but not in the forest) you were not awarded the XP for it...I know these things are about the XP in the game but its fascinated me what caused the code to not give XP at certain points in the game and also the idea that it actually resets back to zero...these things fascinate me for sure I know I said this on twitter but I just discovered your channel recently and its actually blown my mind with how games work...and maybe DON'T at times and while I myself am not a game programmer or designer seeing the insides of a game in some way fascinates me and I hope you continue with content like this in the future Take care

I don't know how many people remember but when Zelda 2 was first released in the US, it was recalled and then re-released a short time later. There was apparently some game crashing bug that made it all the way to production.

I know it’s primitive, but assembly language is just so great to look at, and to understand. It’s just so interesting to see machine code in human readable form, instead of a low-level language masking it up another layer.

You deserve way more subscribers man. Your content is amazing! Absolutely love the specifics on the source code even though I understand very little of programming, keep it up!

Unbelieveable, I never realized originally learning programming and assembly on a C64 that it would have directly translated to so many other applications at the time. I later learned 8086 assembly but hearing LDA, A, X and Y registers brought back so many memories! And to think today I write code in C# that's probably thousands of lines of assembly, executing perfectly in a multi-tasking, multi-threaded environment. UN real where we came from back then!
