About the Game
Jurassic Park: Rampage Edition is a side-scrolling platformer developed by BlueSky Software and published by Sega for the Sega Genesis 1994. It is the sequel to Sega's previous Jurassic Park video game, based on the film of the same name.
In this game, you also can choose between Dr. Grant and the Raptor. Dr. Grant is able to complete game much faster than Raptor due many heavy glitches.
Paleontology
Before we start, world-famous paleontologist Dr. Alan Grant would like say a few words about dinosaurs represented in this game.
Pteranodon (meaning "toothless wing" in Greek) is a genus of pterosaur that included some of the largest known flying reptiles, with wingspans over 6 metres. They lived during the late Cretaceous geological period. More fossil specimens of Pteranodon have been found than any other pterosaur, with about 1,200 specimens known to science, many of them well preserved with nearly complete skulls and articulated skeletons. By the way pteranodon were pterosaurs, not dinosaurs.
Gallimimus is a genus of theropod dinosaur that lived during the Late Cretaceous period, about 70 million years ago. Gallimimus is the largest known ornithomimid; adults were about 6 metres long, 1.9 metres tall at the hip and weighed about 440 kilograms. As evidenced by its relative Ornithomimus, it would have had feathers. Many of the vertebrae had openings that indicate they were pneumatic (air-filled). The neck was proportionally long in relation to the trunk. The hands were proportionally the shortest of any ornithomimosaur and each had three digits with curved claws. The forelimbs were weak while the hindlimbs were proportionally long. The head was small and light with large eyes that faced to the sides. The snout was long compared to other ornithomimids, although it was broader and more rounded at the tip than in other species. Gallimimus was toothless with a keratinous (horny) beak, and had a delicate lower jaw.
Dilophosaurusis a genus of theropod dinosaur that lived during the Early Jurassic, about 193 million years ago. The genus name means "two-crested lizard". At about 7 meters in length, with a weight of about 400 kilograms. Dilophosaurus was one of the earliest large predatory dinosaurs, though it was smaller than some later theropods. It was slender and lightly built, and the skull was proportionally large, but delicate. The snout was narrow, and the upper jaw had a gap or kink below the nostril. It had a pair of longitudinal, plate-shaped crests on its skull, similar to a cassowary with two crests. The mandible was slender and delicate at the front, but deep at the back. The teeth were long, curved, thin, and compressed sideways. Those in the lower jaw were much smaller than those of the upper jaw. Most of the teeth had serrations at their front and back edges. The neck was long, and its vertebrae were hollow, and very light. The arms were powerful, with a long and slender upper arm bone. The hands had four fingers: the first was short but strong and bore a large claw, the two following fingers were longer and slenderer with smaller claws, and the fourth was vestigial. The thigh bone was massive, the feet were stout, and the toes bore large claws.
Compsognathus is a genus of small, bipedal, carnivorous theropod dinosaur. Members of its single species Compsognathus longipes could grow to around the size of a turkey. They lived about 150 million years ago, during the Tithonian age of the late Jurassic period. Compsognathus had highly developed senses and quick legs; had 68 sharp, slightly curved teeths.
Velociraptor (meaning "swift seizer" in Latin) is a genus of dromaeosaurid theropod dinosaur that lived approximately 75 to 71 million years ago during the latter part of the Cretaceous Period. It was a bipedal, feathered carnivore with a long tail and an enlarged sickle-shaped claw on each hindfoot, which is thought to have been used to tackle and disembowel prey. Velociraptor can be distinguished from other dromaeosaurids by its long and low skull, with an upturned snout. Velociraptor (commonly shortened to "Raptor") is one of the dinosaur genera most familiar to the general public due to its prominent role in the Jurassic Park motion picture series. In real life, however, Velociraptor was roughly the size of a turkey.
Triceratops is a genus of herbivorous ceratopsid dinosaur that first appeared during the late Maastrichtian stage of the late Cretaceous period, about 68 million years ago. It is one of the last known non-avian dinosaur genera, and became extinct in the Cretaceous–Paleogene extinction event 66 million years ago. The name Triceratops literally means "three-horned face". Bearing a large bony frill and three horns on its large four-legged body, and possessing similarities with the modern rhinoceros, Triceratops is one of the most recognizable of all dinosaurs and the best known ceratopsid. The functions of the frills and three distinctive facial horns on its head have long inspired debate. Traditionally, these have been viewed as defensive weapons against predators. More recent theories, noting the presence of blood vessels in the skull bones of ceratopsids, find it more probable that these features were primarily used in identification, courtship and dominance displays, much like the antlers and horns of modern reindeer, mountain goats, or rhinoceros beetles.
Tyrannosaurus is a genus of coelurosaurian theropod dinosaur. It is one of the most well-represented of the large theropods. Tyrannosaurus had a much wider range than other tyrannosaurids. Fossils are found in a variety of rock formations dating to the Maastrichtian age of the upper Cretaceous Period, 68 to 66 million years ago. It was the last known member of the tyrannosaurids, and among the last non-avian dinosaurs to exist before the Cretaceous–Paleogene extinction event.
Level by Level walkthrough
Aviary
To fly with pteranodon? No thanks.
Savannah
Not so easy to ride on unbroken gallimimus. It suddenly turn to be real rodeo show from Jurassic Park. At first Dr. Grant almost fell and hung on the tail at very last moment. And then he ride i wrong direction. This way is possible to overflow X-position address and exit from level much earlier than intended.
Cargo Ship
Used zip under the ladder to skip major part of level. During zip glitch is important to interrupt zip at very last frame to be able make a jump from intermodal containers without delay. This level is short, but tricky to optimize because it very laggy.
Hidden Ruins
The only one normal level where Dr. Grant is able to demonstrate his jumping skills.
Optimal movement system is constant jumping and shooting. Shooting is necessary to maintain max speed in air. Jumping cause a lot of problems. All jumps at full speed have same size, so optimal path is very limited, and you can't simply to run a little bit between jumps to adjust position (or will lost many frames). If Dr. Grant will get a hit in the air it will stop him, so such jumping movement require careful enemy behaviour manipulation to avoid all hits. Also if shoot too many times game can lag, so needs to doing it a right frames to avoid lags. In the middle of level used help of Raptor to get a zip to skip part of route. Ride triceratops at the end.
River Run
Dr. Grant is not big expert at boating in strong currents. He fall down on the first waterfall...
Dr. Grant miraculously survived after such dangerous falling and finally reach calm water. What can go wrong now?
Oh no... it is tyrannosaurus!
END
Regarding entertainment tradeoffs
This is superhuman playing session, it mean having fun in progress. So movie includes a few small speed/entertainment tradeoffs (about 1 second in total): One non necessary jump to hung on the tail of Gallimimus in Savannah. 1 frame to take additional chocolate item in Hidden Ruins. Also at very last frame of River Run if make turn boat in normal direction is possible to stopped input 6 frames earlier, however this possibility was ignored becouse of Dr. Grant consider that moving backward is looking cooler.
Possible improvements
I suspect that in Hidden Ruins can be somehow to manipulate Raptor to get a zip earlier. Advanced strategy is to shot him in air to make him fall down on correct platform with no extra jump required, i managed to do it many times, however after it i was not able to activate zip, if this is possible - up to 100 frames can be saved.
Difficulty can be changed to hard 1 frame earlier, even if we don't see it on screen.
ThunderAxe31: Replacing movie file with a version converted for BizHawk 2.3. All inputs are unchanged.
This movie uses the known RTA zips for beating each level astonishingly fast. The techniques are correctly applied and optimized, which puts this run out of the league of RTA attempts, as of the current knowlege for this game.
While this game is presented as an enhanced version of Jurassic Park for Genesis, it does feature such difference in both aesthetics and gameplay that it should be considered as a different game under any circumstance.
The audience reception was very welcoming, so this submission is accepted for Moons.
Amazing run, yes vote !
If needed, the movie syncs on BizHawk 2.3 without changing inputs and I can upload it.
Some inputs by BizHawk seems to do not be used by the game (during loading times) so maybe it can be improved on BizHawk.
Shorter loading times due emulator difference alone is not true improvement but i guess Spikestuff will be happy to have BizHawk version, since he requested converted my previous submission .bk2 just a week ago.
P.S. Try to use advanced strategy for zip in Hidden Ruins which i mentioned in "Possible improvements" in case of successes i will be glad to add you as coauthor.
I show you how deep the rabbit hole goes.
Current projects: NES: Tetris "fastest 999999" (improvement, with r57shell)
Genesis: Adventures of Batman & Robin (with Truncated); Pocahontas; Comix Zone (improvement); Mickey Mania (improvement); RoboCop versus The Terminator (improvement); Gargoyles (with feos)
Ok, you can save 1 frame by pressing Right and Start on the same frame to change the difficulty but at the 3rd level, the movie desyncs... Since I'm not on the good emulator and I don't want to be added as co-author just for that, I let Archanfel tries it out.
As far as i remember when i tried it, difficulty stay normal.
Next submission i will give you better justification why i chose Gens again.

I loved that part in the movie where characters would just shoot straight down through the ground. Yes vote.
Also I agree with Spike here, I would still like to know why gens is still being used. An no “gens is love, gens is life” excuse please.

Seeing how you next project isn’t until 2019 (judging from your signature), this just seems like an excuse to keep delaying your explanation. It’s kinda unfair to people here that you keep doing this. Do you even have a valid reason? If so, what’s the point of delaying it?

LOL why don't you just give him the justification right now? is it related to the next game you're going to submit a TAS?
btw, yes vote, game's short and crazy
I want all good TAS inside TASvideos, it's my motto.
TAS i'm interested:
Megaman series, specially the RPGs! Where is the mmbn1 all chips TAS we deserve? Where is the Command Mission TAS?
i'm slowly moving away from TASing fighting games for speed, maybe it's time to start finding some entertainment value in TASing.

One of main reasons is that my computer works very slowly with BizHawk, especially when i use lua. There are a few other reasons why i still prefer Gens, but i not really want to start emulators discussion.

Yes, related. Hopefully next year i finally will finish Adventures of Batman & Robin, it uses Gens. So to troll Spikestuff in next time i wanted to answered him that it was started by Truncated and i already had no choice when i joined!
Also there are about 5-6 movies i started with Gens some time ago, i not sure will i ever complete them or not (so they absents in my signature), but if i will finish them it will be Gens movies once again.

Gens is hate, Gens is death... just kidding.
On my personal experience using both emulator I can say:
Gens
1. It's faster and don't have performance issues in old machines, even using .luas or another emulator windows.
2. It's easy to use and understand, is useful for newbies who want start TASing Genesis, Cd, x32 games.
3. Linux support I guess, for that marginal group of people.
4. It don't have TAS Studio, so editing inputs with TAS editor can be a little frustating. ( check desync, close emulator, open tas editor - .gmv, save, open emulator, movie and checking for desyncs again )
Bizhawk
1. Using it these days I noticed that have big perfomance issues on my PC, when I open ramsearch, ramwatch or running .luas, the emulator start running very slow. ( I have 4gb ram, athlon II x2 215 ).
2. It can be very confused to use the first times, specially if you come from another emulator and wonted to your personal set of hotkeys.
3. Has very useful tools like TAS Studio and edit the movie in real time.
4. With a good PC is more recommended, not only for sega games, it supports more console emulators.
5. Linux people can't use it, I guess.
Personally I think that they should let people enjoy what they do here and not force them to always use Bizhawk if there is a more comfortable option for them, a movie made in gens has the same effort as one made in Bizhawk and should be valued equally, even if they have "1/2 frames of loading times differences".
Now I would like to ask you, for what reasons do you hate gens? In the site as I remember there are some consoled verified movies of gens. (Idk if hate is the correct word, I'm not native english though)
Now I would like to ask you, for what reasons do you hate gens?
Gens is a highly inaccurate emulator (the re-recording versions are based on a version that was released in 2002). BizHawk uses the Genesis Plus GX core, which is pretty accurate to the original console. Here's the Sprite Masking Test ROM results, for instance:
BizHawk (Genplus-GX):
Gens 11c:
As you can see, Gens actually fails some of these tests. But that's not all. From the VDP FIFO testing suite ROM (titled VDP Port Access Test ROM when actually running it), BizHawk (Genplus-GX) passes almost all 122 of them (only failing #16), while Gens only passes 19 of the 122.
Gens's audio emulation is also garbage (it can't play the audio in Taz-Mania correctly, for one).
And then we have Gens's AVI dumping... it doesn't split at all on resolution change (REALLY annoying when a game changes resolutions partway through), while BizHawk does. Gens also somehow manages to lose one video frame at the 2 GB split.

Its inaccuracy doesn't affect most of the games.
In few games you may have wrong sound (bad sound emulation) like comix zone for example.
In few games you may have wrong visuals - I don't have example on top of my head.
But what I really don't know is: is there any game where game mechanics affected by its inaccuracy?
If no, then I don't care about VDP FIFO tests. It's not so important for superplay showcase.

By most games you just meant Sonic right?
Where were you when Comix Zone was submitted and you could've criticized the TAS' audio? Oh right, you were praising the broken sound.
> The Test Proves This... So-- No shit Sherlock... Let's all go back to snes9x with it's horrible graphical bugs and say screw higan/bsnes.
Comix Zone. Have fun attempting to Console Verify that.
And I don't care about tinfoil hats much like you don't care about accuracy.

Then you, sir, have missed THE ENTIRE POINT of why this website exists. Console verification has always been the ultimate objective for tool-assisted speedruns and this website:

Since they started, tool assisted speedruns were designed to make it theoretically possible, given super-human abilities, to recreate them on an actual console.
I would argue for deprecating Gens altogether, but I'm pretty sure that would kill off any chance of TASes for a Genesis Sonic game in the near future...

It’s very disappointing that TASing emulation hasn’t kept pace with the incredible progress of emulation as a whole. I guess it’s to be expected since just making an emulator itself must be much more rewarding then all the laborious work of adding robust TAS tools.
I certainly wish there was an lsnes equivalent for genesis, but who would do it? If it hasn’t been done by now I think it’s unlikely in the future. Heck, I was hoping for a TAS capable CEN64 by now, but no such luck.
I know BizHawk isn’t a workable solution for everyone , but out of curiousuty what is keeping cam hacks from working ?
