About the hack

Sonic the Hedgehog Megamix (commonly shortened to Sonic Megamix) is a work-in-progress multiperson disassembly modification of the original Sonic the Hedgehog videogame for the Sega Mega Drive / Genesis, developed by Team Megamix and ported to the Sega Mega-CD in the last version. The game features the ability to play as one of five different characters: Sonic the Hedgehog, Mighty the Armadillo, Shadow the Hedgehog, Miles "Tails" Prower, and Knuckles the Echidna. It is an extensive reworking of the original game, featuring new art, music, abilities, layouts, and other things.

Sonic abilities

Sonic's gameplay is based on pure speed.

  • <A>: Light Dash, dash towards a path of rings at 3072 sp/f
  • Double jump: Homing Attack, like in modern sonic games, sonic can do homming attacks when he is nearby a Badnik, Eggpot and monitors at 2560 sp/f.
  • Double jump when not near a target: Jump Dash, a very useful ability to gain instantly speed of 2560 sp/f.
  • Up+jump: Super Peel-Out, It's his exclusive ability in Sonic CD, when release the buttons Sonic starts running at 3072 sp/f, the speed shoes can buff the Super Peel-Out scaling the speed up to 4096 sp/f.

Comments about the movie

Glitches

Interestingly, this hack fixes the glitch called "horizontal underflow" or better known as "level warp" - the glitch that teleports the character instantly at the end of the level, keep in mind that it's not banned by us in the movie, the hack developers fixed it. But others like the "zip" are still present, since it's a routine incorporated into the game engine.

History

The history of this hack in the TAS world is interesting, there were many attempts to make TASes of this hack from the hand of DDRKhat, fano, emu2000, Comicalflop, Crramalama, but for some reason they were not submitted here (I guess because at that time of 2007 the hack was not as developed as now, seeing that team megamix paused his development in 2008, returned again in 2012, but according to the main developer is "paused" actually).

nitsuja started his wip in 2008, but he has discontinued it, and since he left the community in 2012 it was obvious that he would not be able to finish it.

There was an attempt by feeuzz to continue it but he lost his wip and is currently inactive, and recently there was a sub-optimal submission of PLAYERONE that we asked with WST: why not? So we grabbed nitsuja's wip and finished it, we decided to keep his input in order to maintain his legacy since his wip is up to our current standards.

B-B-Boss time! text removed

In this movie the "Boss time" text was removed, the reason is because it only prolongs the boss spawn time, which results in an unnecessary loss of In-game time.

Stages

There really is not much to say about the levels, very high speed here, some zips there, some levels are more destroyed than others, the camhack encode speaks for itself, all the tricks and glitches are the same as you would find in any other Sonic any% TAS, but if you really want specific comments if you don't understand what happens, I can do it, just let me know.

The hack itself

For me, it's a good hack, TASing it was fun and a good experience with my other teammates, the levels are really good and full of atmosphere, the only bad thing for me was the repeatable music of the speed shoes, but beyond that It was nice, it only remains for you to judge and decide if the hack deserve a place in TASVideos along with other hacks published in the past.

Greetings


GoddessMaria: Judging.

Evil_3D: I put it back of respect for the judge, my friends and know the fate of the movie, maybe I'm exalted for the different final boss hits between versions, I'm sorry.

GoddessMaria: Re-claiming...

GoddessMaria: Before anything, I must address the version choice. There are 2 official releases and one that 1 that was an unofficial, incomplete leak. The first being of "Sonic 1 Megamix" v3.0, which is considered the most stable release and is on Genesis/Mega Drive. The most notable thing here is the number of hits the final boss takes before defeated. In the v3.0 release, Robotnik takes the same number of hits as the original Sonic the Hedgehog (16-bit). The next release and considered the most current (and probably final release) is v4.0b, which is what this submission uses. This version made some additions and changes that were omitted from v3.0 such as changing from Genesis/Mega Drive to SegaCD, updating a few zones, adding 2 more characters, and more. The other thing about this version is that, unlike v3.0, the final boss hit count was changed to 1. Nevertheless, both would be eligible for acceptance into Moons. Just not the same category side by side.

That being said, the hack in question is one of the most well known Sonic the Hedgehog ROM hacks to exist and is of really high quality. As for the submission... Does it do enough to justify acceptance onto the site? Yes! The optimization is solid and clear, the entertainment value holds well without dragging on too long, and the audience response has been mostly positive. With that out of the way...

I'm accepting this submission into Moons. Good work to the authors!
