Sonic Primo (SHC 2023 Demo)

By RobiWanKenobi

This is a hack of Sonic 2. It features Sonic & Tails stopping Eggman from his mayhem, in this two zone demo, you'll find something okay in it.


Smooth Rings

2 shields, Blue, Regular; Grey, Ring Attraction

Character Select Menu

Sliding In HUD

PCM Drum Sample Driver written by me that doesn't use DPCM, and supports wav files

*Custom Bosses*


Crimson City Zone and Trap Temples Zone.

Yes, the level names have alliteration.



Jump: A, B, C

Double Jump: C when jumping, you aren't in a ball

Stomp, B when jumping, you are not in a ball

Air Curl: A when in the air not in a ball, you can not trigger jump moves

Spindash: Down plus A, B, or C

Peelout: Up plus A, B, or C


Jump: A, B, C

Flight: Jump and then A, B, or C

Air Curl: A when in the air not in a ball, you can not trigger jump moves

Why it is called Sonic Primo:

Because of a Linkin Park demo

Primo (I'll Be Gone 2010 Longform Demo)

Anyways, untill I see you next time;

Just carry on, and miss me when I'm gone. Oh don't let anyone take my place. Take my place.

By the way, no one has permission to make a recolor hack of this hack.

I spent waaaaaay too much time on the technical side of things on this hack, the likelihood of this hack continuing is low.

Just give this hack the Polygon Jim award or something?

im sorry, but this hack is just... what? the first boss is just easy because the ai is presumably fucked same with the 2nd boss cuz it has nothing to hit hammers with. the music is sooooo offtune and just sounds bad! level design is ok i guess (first zone, at least) 2nd zone makes 0 sense. were you even trying or did you just rush yourself to get SOMETHING out?

The second level's boss arena was made with a different version in mind, IF I continue this, it'll be fixed so the hammers hit the ground.

Nice hack bro, I didnt liked too much the second zone but the Breaking the Habit smps was pretty good

Also, the gameplay was pretty good

Barebones, although sometimes you want to laze around - if that was the intention, this hack fits the bill.

Veeeeeery rough around the edges, although I didn't managed to glitch or crash anything. Not sure what are your plans with this hack, but get back to work~!

Time to ruin your day. This hack is actually canceled, i was planning on more, but i have some other hack that i want to work on instead. I'll keep Primo's source around in case i do pick up again, but that won't be for a long time probably.

In short, i am not getting back to work on this hack.

I like the character redesigns, but the boss fights were way too easy, since they didn't have attack patterns of thier own. I also found the second zone's art static non-animating art to be odd.

Aparently, the story is really.

Eggman stole sonic's pasta, and so sonic has to get it back.
