I can't figure out how to put in one of your game genie codes in Retroarch, you go to cheats and then select NES, select the game, and then it's just a huge list of game genie codes (but yours isn't in the list for Retroarch) and there's no way to add a code manually. I messaged Jane's Rolfe and Mike Matei about making a video trying out your fixes, I'm sure they would love it. Fingers crossed that they find out about this stuff. That would be cool to watch.

I posted this on the last vid but nobody replied. =< Like, is there a way to get it back to 60 fps and make the code optimal enough to run efficiently? Do the enemies HAVE to respawn immediately? (Probably would fix the above issue if they didn't) Do the turtles' velocity HAVE to stop when they hit a ceiling like that? Make the turtles' weapons MAKE SENSE in their damage and other attributes. Such as: (the higher the number, the better. These are just rating numbers, not frames or anything. Range: the larger the num, the longer reach) Attack: higher num, stronger attack Speed: higher num, faster attack Stun: higher num, longer stun Knockback: higher number, more knockback Leo - range 3, atk 3, speed 3, stun 3; knockback 2 (balanced) Don - range 5, atk 2, speed 2, stun 3; knockback 3 (ranged/keep away) Mike - range 2, attack 2, speed 4, stun 4, knockback 2 (stunner) Raph - range 1, attack 1, speed 5, stun 1, knockback 1 (quick damage, basically multi-hit like bombs or the screw attack from Metroid) With this you could switch turtles for the situation you are in, though it would be slightly cumbersome to pause and do so. But you'd get more mileage with each turtle this way, and overall more fun! I have forgotten, does Select do anything? If not, and if possible, the game could pause and you could quickly select the turtle. Ah, I think it allows you to switch sub weapons..so it could still work that way, with the pause function still. Up/down to select the turtle, left/right to select the sub weapon. What do you think?

REALLY liked this one! As a game designer, rather than a programmer, this is the kind of thing that really gets my motor running lol And with that said, I don't really love the "just double the attack speed" solution, both from a balance perspective and from a "feel" perspective. Just being able to mash at infinite speed is fun for a bit, but doesn't generally tend to make games better, most of the time. I understand that a lot of what you did was in service of "quick and dirty" solutions to make them easier to implement for the sake of the video and allowing for applicable GG codes. So this isn't a criticism of the video at all. But assuming that we just had free reign to do whatever we want (while still trying to maintain the spirit of the game as originally presented) let's think about how we can do that! For Leo, I agree with getting rid of the two frame windup. Gone. Between that and fixing the audio bug, I think most of the "input lag" issues would be resolved, and the big problems with the animation revolve around slow feeling response time due to the distribution of active frames. Which is to say it's not input lag or animation length that's the problem, rather that 33% of your attack time is spent in the largely useless overhead position. To preserve overall feel and balance, instead of simply cutting the entire animation in half I would prefer more of a "redistribution" of frames over merely deleting them. Cutting JUST the overhead from 4 frames to 2, and adding them to the lower position will give the swing a bit of weight while increasing responsiveness and extending "useful" active frames. I would also experiment with things like 2-2-6, 2-2-4, and 2-4-4, as well as MAYBE shortening the cooldown. Leo always felt pretty good to use cause of good range and power, so I think he just needs a tweak to help timing attacks and "feeling right". Donnie I think just needs a similar, though simpler, tweak. He's already the most powerful turtle by A LOT, so anything that's just a straight buff would be game breaking. For him, I think cutting his wind-up in half (by four), and his starting "rear" attack animation by two, but adding another 6 or 8 frames of rear attack animation after the main hit would feel really good. The active forward frames would come out six frames faster, but with the same number of total frames (or +2 to to compensate for the faster activation). I might even do something like cut the cooldown by two and add another two to the forward strike, though again you want to be careful of making him too strong, and also holding a position for too long can start to feel really weird. Great video once again! The deep dive code walks are great, but this one was right in my strike zone for fun and interesting content 😂
@angeldude101 Жыл бұрын
It's perfectly reasonable to have long animations and cooldowns for balancing. What I'd consider most important is that the animation starts as soon as possible after the input. The hitbox doesn't even need to start immediately, but at least start the animation to give that feedback.
@VinsCool Жыл бұрын
Man that is so much to unpack here. A lot of optimisations in the code really hasn't been done before release, and it shows. I'm willing to bet if someone went the hard way to disassemble the game, and rewrite it entirely from the ground up, it could totally run at 60fps without that nasty input lag, or full lag frames implemented by design to compensate the whole thing for that matter. The controllers input lag is especially disgusting. I knew the game really felt delayed, but I never expected this huge amount of lag between a button press and the action being processed, even less expected the chance of an input being missed entirely, even from being aware of the DMC corruption, I legitimately have expected it would at least have done this part properly, but nope, not close to it! Fantastic video like always, I love this stuff a ton, especially these days where I have gone deeper and deeper into 6502 Assembly programming, and realise how clever you really have to be when you make your code do things efficiently.
@VinsCool Жыл бұрын
And I mean, seriously, it's so much harder than one would think it is at first, especially when you try to do things you just have no idea how to process the most efficiently. And I say that as I legitimately felt bad for having 1 single frame of lag with the input handler logic from the first and only game I've ever coded all by myself so far, a Pong clone which uses the Atari paddles as the source for sprites positioning on the screen, haha! Maybe 1 frame between the input and the display on screen is perfectly reasonable after all!

I always thought of Donatellos attack lagging more was out of compensation for the distance covered by his attack. Which always came in handy when dogging Rocksteady on the crates. So I can't say if it was by design, and if so, whether it was good design or not that each turtle has its own balance of speed, distance, and direction of attack. Either way this was a really good video and I absolutely loved the music playing through out it.
@DoomRater Жыл бұрын
Yeah I'd give Raph Donatello's damage to make him useful, and Don could take Mikey's damage and Mikey uninjured could use Raph's. Mikey does enough damage below half health to one shot some things, but the killer is that Raph's 9 damage is the lowest when turtles are wounded. This means his unique advantage of killing flying enemies in one hit is negated once everyone is injured enough, since every other turtle's damage is 10 or greater at that point.

Rebalancing TMNT could be a lot of fun. For example, Raph is the second strongest turtle at full health but the weakest at half health. I would give him Donatello's damage values to make up for the fact he has such a terrible hitbox, making him a viable character right away. Don could benefit from a faster attack and then get Mikey's old damage values. Mikey having Raph's damage values makes sense to me as well, leaving Leo mostly unchanged.

@@autobotstarscream765 While I do think these rebalances make sense, the manual writes that Leo is good for energy conservation, Mikey is courageous, Raph is good against flying enemies, and Donatello is powerful. Leo being balanced in my book was leaving him in third place and fourth place for damage since he has the best weapon coverage and second best reach. Actually, wrote up a table really quick: Leo's wounded value nerfed to 8, Raph's healthy and wounded buffed to 15 and 17, mikey's healthy and wounded buffed to 9 and 15, and Don's healthy and wounded nerfed to 7 and 12. Mikey still gains more damage from being wounded than any other turtle and it's actually buffed from 5 to 6, and with this change Leo never makes the new anti-air turtle Mikey worthless, because it takes 9 damage to kill the flying enemies.

That would require *way* more than a game genie code. Those enemies respawn because the game doesn't store the fact that the enemy spawned by a particular spawner was killed. It only stores whether that enemy exists or not. If it doesn't exist, and the spawner is reached, it will be spawned. You would need to turn a two-state system into a 3-state system (unspawned, spawned, killed). That's outside of the bounds of a couple of Game Genie codes.

Fascinating video! Keep up the good work!
@user-a5Bw9de11 ай бұрын
While this is not a definitive answer, comparing Castlevania with Contra, I would assume Castlevania's design is intended. When Simon jumps, there is no way to fix the trajectory, just like IRL jump. (Both Contra and TMNT have a jump physics with leeway to aerial horizontal movement) Also in IRL, using a whip requires some wind up time or it just falls flat to the ground. The jump feature and the attack feature in the game suggests its players with methodical approach to beat the game than "just rush-in, dodge and kill everything" approach that Contra suggests. (It is hard to say what the devs intended for TMNT because it falls somewhere in-between and then steps sideways.) If input lag was normal for Konami games, I don't think Gradius or Rush 'n Attack ever became popular.

Also turn on GPU Hard Sync with 0 hard sync frames (if using the gl video driver) or set Max Swapchain Images to 2 (if using the vulkan driver) to force the graphics card to output new frames immediately like a console would. Finally, set Frame Delay to 13 and turn on Automatic Frame Delay to compensate for USB controller lag.

It’s actually interesting that 1 pin in the nes is used for both control reading input and pcm reading playback,it’s a flaw of ntsc nes systems wich was fixed in the pal nes, But games had to be designed around this in case it uses the pcm channel,by reading things twice and let go if it find a match and ignoire it if it finds no match in those control inputs, Now it’s interesting that SMB3 does immediately enother check if it failed to find a match while TMNT1 does not a second check untill the next frame,BUT still in both games i actually noticed no dramatic input lag(probably because it all happens in nano seconds) BUT i do wonder why nes games with pcm playback not just give button presses a higher priority over pcm playback because is gameplay not more important then pcm playback? Am also curious how and if pal versions of games were redesigned to take advantage of that fixed flaw of pcm playback & control reads from ntsc nes systems,or if those game deves didn’t bother and just leave the source code of those games as what they were, BUT that brings me to me next question,how about pal games with pcm playback wich does take advantage of the pcm & control reads bug fix,how will those games gonna behave on a ntsc nes,will they behave strange or just crash altogether or will control reads or pcm playback be not registered??? BTW,It’s also incredible that the nes controller uses a shift register rather then multiple wires for button control reads,considering that shift refister chip can only process 1 button press at a given time,BUT since it can process 1 million instructions per second,it can virtually process all button presses atonce,even turbo button presses,all without crashing the game or getting overloaded,and all without any notice, Altrough i found supermariobros 1 just feel slightly smoother to play then supermariobros 2 & 3 wich is not surprising since that game didn’t use any pcm channel at all.

Good video, i have to mention thou that emulator lag is a solved issue, there was a period of time while ago where gpu drivers were way too optimized for thrughput , input lag be dammed and no way to deal with that from software side. Thank god we past that and now any emulator or program can have input lag down to raster lines if they care to.

This has been super interesting, if you want an interesting yet really flawed FDS game to dig into I'd recommend Relics: Ankoku Yousai it's an interesting example of a first-time nes dev getting really ambitious and not writing the best code as a result. Underneath the rough design feels like a really fun game though. I'm planning on taking a whack at fixing it someday and am definitely gonna reference your commentary on design fixes in these.

I typically use Raphael or Michaelangelo in the BOMB DEFUSAL LEVEL (sacrificial lambs) but I also tend to use them - especially Raphael in the later level with the flying enemies. Raphael and Michaelangelo kill most fliers in one hit while Leo takes more and Donatello's attack is too awkward to use while jumping. Raphael is better at attacking enemies diving towards him from above than Michaelangelo. Donatello and Leo's strength are being able to attack through ceilings and floors. Each stage lends itself better to a specific turtle and like MEGA MAN games, you just have to figure out who to use and when to use them. I will usually equip Michaelangelo with BOOMERANGS and always switch to him when I find them so I can add to his ammo. I will usually give Leo and Raphael throwing stars - especially the triple-star ammo. Donatello gets the KIAI SCROLLS since he's so powerful in the Technodrome level's final hallways. I can kill shredder from a distance with whatever weapons are leftover.

It's interesting that despite Don's excessive lag he is still the most popular and considered the strongest by most players due to the higher damage per hit mixed with the longer range. Certainly any fix would need to make some attempt not to just expand this imbalance even further.

I have been playing the Cowabunga Collection's TMNT NES version but I still have the original NES version for NES. It really feels to me like the newer games are more difficult. IT feels like enemies had their health buffed - or conversely the turtles had their attacks weakened.

Goes to show how powerful hitbox detection is when even with all that lag on Leo and Donny's attacks, they are still the better of the 4 characters (although part of the reason Donny's is so much better is because he outputs way more damage than his brothers).

Watching these just makes me think about how much of a gift it would've been to the original devs to have the emulators and debugging tools we have now. It's easy to criticize the flaws in games like this, but man, they were really working with stone tablets and chisels back then. Haha

Now I want a GG code for giving all turtles the attack power of Donatello and combine it with faster times for Leo and Don, that playthrough will be awesome!
@GeneralBolas Жыл бұрын
Why would you ever use Donatello in that case? Leo has almost as much range (especially up and down), and his sweeping attack hits a lot of stuff. The only think that keeps Leo from being OP is that he only does half-damage. Rebalancing this game would be a good idea, but I don't think you can get good gameplay just from timings and damage changes. You'd really need to redesign the attacks themselves.
@Dark.Shingo Жыл бұрын
@@GeneralBolas I do agree, but at least I would switch between turtles more often instead of just using Don and falling back on Leo when afraid of losing him and use Mike and Ralf as sacrifices. Also, obviously just doing this for fun and mess around.

DMC fix seems great. Not sure about frame adjustment on start, if only because Leo/Don are already the more useful turtles. I can't recall progressing anywhere in the game without Don usually being the main turtle, especially on bosses. That said, I'd be interested in a build with tweaks across your various videos about this game.
