This is one of those times where you actually have to play both to appreciate the differences. the genesis version seems convincing until you go back and play the arcade. And i'm getting the feeling this was intentional, to rudely surprise people intending to coast through the arcade on credit after mastering the home version.

I get why this went to vault, and why the nes version went to vault as well. And the genesis version. Everyone who's played the game seriously knows that nes and sega genesis versions of the game are totally inferior to the good versions. It's the "looks like good RTA" issue that's the real sticking point here. That and the fact that it seems to drag on a bit. but that's a minor secondary issue. While you feel like a superhuman when you get the games controls, that doesn't really translate well to viewers, so only ones who have played the game (admittedly a decent number) appreciate it properly. The Sega CD version is a highly accurate port, including all bugs from the original that might help that I know of. (overflow trick is a BIG time saver on level 12) TG-16 version is nice but not an accurate port. it does have silly bugs of it's own allowing some clearly not intended solutions, and the same speed control options. Incidentally 2 tile running jump is actually a bug. All puzzles are solvable without it, except for maybe SNES version. But it's a cool bug which was sadly fixed for prince of persia 2.

I got pretty fast at the genesis one, using combination of downstab abuse and knock off the edge abuse. I will accept that at really high level the genesis one is probably harder to squeeze time out of, but a decent run is much easier on genesis than on the arcade. and playing for survival the genesis one is a TON easier. enemies are a lot easier to charge attack (unless you are axe battler), a lot easier to special attack and a lot easier to down stab reliably. he knight can reliable be charhe attacked by the other two characters on the enesis. in arcade he will swing his sword earlier. Only death bringer is any challenge, and that mainly because of the invincible skeletons.

Wihile shorter this version is overall more difficult. the AI is smarter compared to the genesis version, and the monsters have moves they don't have on Genesis. Run RTA without amazing skill if you try the stunts that are so easy in the genesis version you will get murdered. On genesis all you have to be do is be JUST above bottom and down stab and enemies try to dodge low. they are smart enough to dodge hig hin arcade. the slow slice exploit also doesn't work in arcade which accurately tracks your swings at all times. This TAS make it look easy. it's NOT. In non TAS conditions, most players will abuse the ridable animals and magic, and this will easily get you to level 4. Then it starts getting tricky.

While this is entertaining, it's mainly entertaining to those who have played the game. It also doesn't look THAT superhuman, because of the slow game speed. every stunt is pretty much doable RTA,or looks like it. My proposed SegaCD tas would solve that in a hurry, by using high speed mode for move and fight it runs at 60FPS (pretty sure). maybe 30. Will look much more superhuman. :)

I have the version of the Sega CD. I had also thought about it, but I do not know to adjust the speed of the game pausing during the game can be allowed. Maybe this function going to break a rule of the site or not.
it is done during ingame pause menu. therefore it's allowed. press start during gameplay, go down to speed (move) press a, press left a few times. do same with speed(fight)

This is a very nice and extended version of Prince of Persia. Also despite the engine extensions, the perfect play control form the original is kept here. A very nice run. The original version pf PoP is still great though. I recommend TASing the Sega CD version next, with use of the speed adjustment feature to speed up the action. :) should be quite entertaining seeign th egame blazed through at speed 1

There are a few circumstances. 1) power is removed from the system for an extended period of time. this should be the state the emulator presents. what initial states can happen after an extended absence of power? The game that doesn't boot in FCEUX and does on real hardware seems to prove that FCEUX initial state is NOT a valid one by those standards. it's initial state should be one that is likely to happen on a real console. 2) power is left off for a very small amount of time. this causes a minor change in state from what it was when it was powered off. on my c-64, for example this tends to cause one bit in each ram cell to flip on. the same one. this cannot be accurately emulated, so it seems this is NOT valid. 3) power is never actually dropped because person holds reset button while removing cart 1 and inserting cart two. this is possible on real hardware. so it's a valid TASing trick, in my opinion. you dn't even ave to press reset until after swapping the game. a real life example here https://www.youtube.com/watch?v=wyiBuX9y16k the movie attempted a variation of number 3. according to nesdev people, uninitialized ram after long term poweroff is mostly FF, with some memory locations having a single bit at 0. this confirms my experience with c-64 that a quick power off and on flips one of the bits to 1. So seems FCEUX is wrong, and that Nestopia is more correct. However, someone changing games reasonably quickly can produce a very different result (not an uncommon event in real life). So seems "random" initial state should randomly select values from the following pool FF FE FD FB F7 EF DF BF 7F with an extra high priority given to FF if it's to reproduce real world conditions from long term poweroff.

I have an idea for a time improvement. it may be faster to collect one coin then to collect zero coins if you area already going into subspace. if you collect a coin, the slots spin immediately and accept input, allowing you to stop in a loser well before starting fanfare ends. i tested this part with arpid fire an drel time play. the question is which is longer. the detour to collect one coin from subspace or the wait at slots?

It just feels wrong not playing theough the bonus levels. This is one game wher the fastest completion is not the most skilful.

Well if i had the same ideas as he had, i'd not only have a force close (with a clear message that it's intentional) but a forced delay after the close, if the close was triggered by going too fast. Anyway here are the current issues as I'm awate of it. 1) you can't get the golden ending without getting a neutral ending first. SO any attempt at the pacifist ending needs to start from a save. 2) the game's content changes with each reset. Yes, the game is aware that you are starting over. 3) only the genocide ending can be reached th first time through without the game closing on you. 4) the genocide ending actually taints the golden ending, if you do it first, you monster... The closing down invalidates anypercent, which is the fastest. Genocide will be slower, but can be done the first time through. The only way to make a TAS entertaining that I can think of is to use tas only glitches. And i could easily wrote a program that interferes with real time speedrunning of itself without crashing. Two ways. 1) unfriendly RNG/dynamic difficulty, that gets more unfriendly as you progress, and gets friendlier with time passed. 2) put in enforced delays that anyone who is even trying to speedrun will run into.

Kinda silly for them to do the save in triplicate and not bother with comparison. For reference, the save corruption check for triplicate saves is ridiculously simple. Load save 1. compare each byte with save 2. if no difference is found, start game, if a difference is found, then copy the bytes from save 2 in starting at where the difference was. compare each byte in save 3 with save 2. if they are the same, start game. otherwise load first save and start game. Such a save system is foolproof, assuming that save corruption is a partial save.

I remember back in the day there was a 13 note fast tune that was easily half the length of the others, and there not being a huge pause after it, though that may have been the original jumpman.

The main potential imporovement i can see would be manipulating shorter end of level tunes. they arent' all the same length.

I admit i was laying it on a bit thick, but my point was that for a 100%, there was sure a lot of stuff skipped. :)

Too late to vote no because 1) Doesn't complete a treasure ship 2) doesn't collect all white mushroom houses (you can't call it 100% if it doesn't get those...) 3) doesn't flip the mushroom house panels (yes I know it requires no skill, eats time and is not entertaining, but if they can be flipped, they must in my opinion. and you can manipulate items from them to help you) 4) doesn't collect the spade panels (each one is 5 lives, so should be able to get to 99 that way. Again, those are panels not flipped...) 5) doesn't complete an n-spade panel (really only need to insist on one of those) 6) doesn't beat an airship with any of the special suits, much less all three. (these give you unique messages from the king, and are thus skipped content.) 7) doesn't collect all the big ? blocks. 8) doesn't show off the 3 of a kind animations. 9) doesn't use kuriboh's shoe. :) This only qualifies as "all levels" in my opinion. :) I'm well aware that many of these cost time, and many don't really show that much skill, but many of them can in theory save time elsewhere by making more map powerups available, which would be more entertaining.

Not only does this show the credits, it also kills Bowser. So it seems clear that this is a playaround that completes the game. :) (Now if someone will just make a run that programs SMB1 in SMW, then TASes it..)

Seems the author attempted to design the game such that it's impossible to speedrun and get a good ending. He might have even succeeded. He's saying not to post speedruns because if you are even trying to speedrun the game, you are playing it wrong, you horrible monster. :) If i were the author i'd combat this by forcing the game to close if you manage to be too perfect, placing an upper bound on the time possible for a pacifist TAS, to make that endeavor pointless.

I believe this may still be improvable. both players must have bonus scores as close together as possible and number of nibbly pibblys eaten as close to the same as possible. There's a noticeable difference in level 5, for example.

There are significant version differences with arcade versions that affect TASing. There are two main arcade variations. one with DOUBLE giants on level 7, and one with single giant. There are other enemy placement differences, as well as differences in the behavior of the giant devil boss of 5 and 6. In the US version, not only are there TWO giants instead of one on level 6, but the giant devil boses have double hitpoints, as well as a very brutal attack pattern where it actively homes in on you for the kill, making it insanely diffiuclt to beat with the shield. The version tased here appears to be the double giants version, which later has 1 instead two golems, and double health on the level 5 and 6 bosses. HOwever i think the US version (only) has much nastier AI for this boss. There is a wrong warp that exists in the arcade https://www.youtube.com/watch?v=NQPqFu1JA60 usually it sends you to 4b, but it's rumored to be able to sometimes send you clear to level 5. if this can be reproduced under TAS conditions, it would save time, if you can manipulate a shield later. Btw, for those who think this TAS is not entertaining, try to beat the game unassisted. :) You will appreciate the game getting demolished. PS: the reason super mario all stars doesn't obsolete smb is because smb was the original game. in this case, the arcade version is the original. THe NES is pretty good, but not quite the same port. And its kerky with bad sound, and uneeded delays. There ARE significant mechanical differences though, so i can use the argument that both runs should exist.

Vault is appropriate for this style of game. there's no superhuman skill shown, just good route planning. There' no luck or reflexes involved at all, and no glitches used. if a different mode is played, then luck manipulation could be shown off, which should make it more interesting from a TAS perspective.

ACtually that jingle was here first. (actually it was in ZANAC first, i think) Tyrian ripped it off from there. :) Other categories that i think would be good. 100% (all corridors, all subweapons maxe,d all bosses killed, all defense/shot/onsecutive fires collected. no damage. TGL password mode (corridors only, hard!)
