Sonic 1 and 2 Jammed Into One ROM

You don’t need no stinkin’ Sonic Compilation here!

Sonic Retro Tech Member ColinC10 has consolidated both Sonic 1 and Sonic 2 into the Sonic 2 ROM to create one epic, seventeen-zone adventure.  While adding spindash to Sonic 1 has been done a bajillion times, this hack brings the entire Sonic 2 presentation over, including sprites, HUD and title cards.  What caught my interest the most (and why I’m even blogging about it) is the emerald count.

The 6 emeralds from Sonic 1 and the 7 from Sonic 2 all have to be collected to complete the game and obtain Super Sonic.  The way you access the different emeralds works the same way and you can collect an emerald from each set in a given act.  What this setup creates is an emphasis in exploration and ring collecting to maximize the amount of emeralds that you can collect in a given zone.  I enjoy this challenge.  Of course, you can ignore the emeralds altogether.

It’s great to tackle all of the levels of these two games in succession while carrying over your score and lives, too.  An “Arena Mode” is also available that gradually ups the difficulty of the levels, making their layouts harder and enforcing a stricter time limit.

If you feel like marathoning some Sonic this weekend, download this hack.  Be sure to watch Tails get annihilated three ways to Sunday in Marble Zone.

This is a fantastic hack. Well played. It always amazes me how these guts create these hacks.

sonicwalter

it should include sonic 3, sonic and knuckles and the start dash. but on the bright side, it’s good

Jakeiiii

WOAH!!!

Sonic&Tails

Great, may be someday we will be able to play Sonic 1, 2, 3 and K in one hack.

Jix Hedgehog

WHAT? No Shadow?

Just kidding. Brilliant idea combining the 2

Tails in Sonic 1

CooooooooooooLll…………;)

How did they manage to fit Tails within the MegaDrive’s 64-colour limitations?

kaoz

looks great =) might check it out.
Better go and find an emulator…

Just had a blast of it on my psp, awesome Rom, i’m so gonna attempt to go through it all on my next train journey 😛

Starlight

This looks very interesting, might check it out if I have the chance.

@Extaticus: There’s a lot of trickery that goes on to get around palette limitations.If you look super hard, you can see a few colors that are slightly off in the Sonic 1 levels.

The problem that having Tails along for the ride is that the ROM gets super laggy in certain sections of Sonic 1 levels.Luckily, you can switch characters out mid-game by returning to the title screen.

Now how ’bout Sonic & Knux with Sonic CD 😀
Still cool tho

Ah, we have some talented hackers in our fanbase. Makes me proud.

I just downloaded this, but how do I play it?

Brad Flick

With a Genesis emulator.I recommend Gens or KEGA Fusion.

LolWutermelon

Just finished this, took endurance to reach the end… However it was great to play both games seamlessly (and I also liked the fact that I had all my lives to replenish after sonic 1; I finished with 1 life).

Only problem I had was some lag during labyrinth zone and scrap brain zone…generally just underwater. I blamed my pc at first but it could be a problem with the rom…eh.

Tiny

thank goodness for psp firmware. im adding this to the library!

personguy

So wait, all 13 emeralds…

Where’s my hyper sonic mang?

Syaming Li

@personguy …All these years and you still dunno Hyper Sonic was 14 Emeralds? =P

Looks pretty darn awesome. Think I’ll give this a whack on my HTC Gensoid during my train journey today!

YoshiAngemon

I downloaded this game, plus the Kega Fusion. Feels more smoother in the Sonic 1 Zones. Almost, Sonic 2 Smooth.

YoshiAngemon

Okay! The Special Stages are harder than the original, WHAT’S THE CODE to unlock Super Sonic?

Reevys

Gonna give this a download and play it when I’m next on the train. 😀

WITCHCRAFT! PURE UNBRIDLED WITCHCRAFT!

Well so far I’ve played the Green Hill Zone and I must say I’m impressed. It is a challenge to find 50 rings then either find a star post or carry to the end of the act. It would be cool to play s1-s&k in one straight forward game. I myself always wanted to have a hack of Sonic 3 & Knuckles Chaotix in one game, meaning have the Chaotix levels incorporated into Sonic 3 & Knuckles.
