. . . Backround of Act 0 is awesome!

Oh my, that was splendid.

I never noticed, but if you run straight, then roll, and immediately jump after, you go significantly faster. Wonder if that could make for an interesting tool assisted speedrun.

That's the same technique that can be used in the 8 bit version of Sonic 2. If you roll onto springs or roll jump onto springs. You can travel faster than a normal jump would do on springs. I found out about this speed roll when I kept on dying on Green Hills Zone act 3 with those bloody death spikes. Also. If you roll in water in Aqua Lake Zone, then jump to the surface, you will bounce across it without the need to roll from the ground outside the water.

This roll is also amazing for cutting corners in normal zones where normal jumps just wouldn't have the reach to do some jumps. Give it a shot with the 8 bit rom. It changes the game entirely.

Great start with the hack so far. The Sonic sprites look great.

Glad this is still WIP. I thought it was on the same place of the Hybridization Project =P.

Skeledroid · Apr 5, 2010

this is going to be the best hack. :}

I know that the party is over and everything, but, could I ask you to finish this level? Just to see how it will play out. I really liked it, and I find it a really interesting concept for upcoming projects, if you know what I mean...

Also, congrats for the brilliant idea!

Fred Wood · Apr 5, 2010

I gotta second endri here on this one. It'd be fun to have a complete world 1-1 in the Sonic 2 GG engine.

Albeit completely stupid.

And awesome.

I'm still working on the physics. I haven't had the time to really dig into it yet. Unfortunately, other things must take priority . I know this is a bit of a "nothing" post, but I thought I'd let you guys know that I'm still around.

Any info on this, is it on hiatus, or dead?

tokumaru · Jul 22, 2010

I miss this... I really enjoyed making some sprites for this project!

Glitch · Jul 22, 2010

It's most definitely not dead (as far as coding is concerned). I started work on rewriting Aspect Edit in C but I haven't had time to finish anything yet. You guys have put some top quality work into those sprites and I don't want that to go to waste.

NAME OF HACK: Sonic 2 LD

GAME OF ORIGIN: Sonic the Hedgehog 2, Master System

EMULATOR COMPATIBILITY: Shouldn't have any problems in Fusion or Meka

----------------------------------------------------------------------------
DESCRIPTION OF HACK

Attempting to recreate the experience of the Mega Drive version of Sonic the Hedgehog 2 using the engine of the Master System version.

Hack is in very early stages, only features Act 1 of Emerald Hill Zone and is devoid of enemies.

Loops are broken until code has been located and modified.

There is a known minor collision bug with the quarter circle ramps, please do not use at high speed =P

Although the game isn't particularly polished, I decided to enter in the contest as a proof of concept, with possible chance of some kind of technical achievement award

----------------------------------------------------------------------------
TOOLS USED: XVI32, TLP

DISASSEMBLY USED (if any) none, yet

----------------------------------------------------------------------------
WHAT DID YOU CHANGE?

Intro, Title screen, Act Title Cards, New test level, Layout, art, sprites, object placement of EHZ1

----------------------------------------------------------------------------
SPECIAL THANKS TO

Programming: Glitch

Background Art: BlackHole, Orcrilio

Sprites: Tokumaru, MoDule, Polygon Jim

Hack Name: Blanche Hodapp

and the Sonic Retro Community for their invaluable feedback

I've entered the first beta into the contest at the last minute. It really needed some more work but I didn't have time.

I suppose I should give a little update. I haven't done much in a long time, but after meeting with Shadow Fire at the Retro Oz meet, my interest in this project has been rekindled. I investigated the quarter circle ramp glitch and have come to the conclusion that no matter how much I play with the collision, having the ramp split across two metatiles is always going to cause the glitch. I tried creating the ramp within one metatile, but it just doesn't work within the current engine. I'm going to replace them with 45 degree angle slopes, and it doesn't look too bad and it avoids the glitch.

Next I need to get the loops working, and Glitch has pointed me in the right direction, but it's going to take me some experimentation to get them to work. Once I do that, I'm going to move on to Act 2. I'm really itching to move on the CPZ, but I can't leave EHZ in such an unfinished state.

Somehow, Glitch and I need to work out how to get our two sides of the project to work together. I'm not very keen on moving to assembly, even though I can see the benefits of moving out of my comfort zone, and Glitch isn't too keen on disassembling my ad-hoc hack and slash methods of hex editing. I guess I should stop being lazy, but I just haven't had time to get my arse into gear.

I used to be able to work on this project in my spare time at my old job, but my new job doesn't allow external drives or software being used on their secure systems, and my access to the home laptop is somewhat limited, so it's going to be painfully slow going. Sorry to anyone dying to get their hands on it - it might be a while.

Is this project still going?

dsrb · Aug 19, 2010

Did you even read the latest post?

Agobue · Aug 20, 2010

Yes, he said it would be a while, but I just wanted to make sure that it hadn't died completely.

doc eggfan · Aug 23, 2010

Yep, still working on it.

Jimmy Hedgehog · Aug 23, 2010

Oh wow, this looks like it'll be one heck of a game to play once it's done

doc eggfan · Aug 29, 2010

A request

An 8-bit version of this

to replace this

tokumaru · Aug 30, 2010

I gave it a try too:

This one is tough, the target size is too small!

Retro_Stew · Aug 30, 2010

Made a few changes :p
