Sonic and Sega Retro Message Board: Overbound - Viewing Profile - Sonic and Sega Retro Message Board

Just copy pasted my SFGHQ topic. Maybe these should go on the wiki eventually.
Since it seems near impossible to find the good Game Maker Sonic engines I've made this post and hosted many of the engines on my own site to provide easy access to anyone looking for engines.

Sonic Dash/Xmas Engine

The best engine for GM period. Very smooth and lots of features.

Dash/Xmas was created by Damizean & RougeYoshi and are provided free for use.

Sonic Dash Current(Recommended)

This is the most current form of the Dash includes monitors, shields, parallax, dipping bridges, rings, springs, Sonic, Knuckles, and Tails with S3&K moves and following partner.


Xmas Gift Engine

Similar to the the above engine only less advanced. This engine includes: rings, monitors, parallax, shields, Sonic, Knuckles, and Tails with S3&K moves and following partner.

Sonic Dash Old Engine

This is a very old version of Sonic Dash which has some bugs. I recommend not using this version. That said there are many gimmicks included in this version which can be ported to a newer version without to much trouble. I won't mention them all because there are a lot but its enough to say that it consists of a whole zone which can be played through so everything one would need to do so can be found here even a boss.

Sonic Revival Engine

Sonic Revival Engine Thread

The Sonic Revival Engine 2.0 (Mirror)

This engine was made on top of one of Dami's older engines and is created by Chaos Rush. It has shields, Sonic, Knuckles and Tails and a few other things. Its less advanced then Dash but some may say its easier to use if you don't understand states machines.

Kain's Sonic Engines

S3&K GM Engine (Mirror)


This is Kain's attempt at a Sonic 3 engine there's a lot of stuff here including spikes, monitors, shields, rings, badniks, and more defiantly worth a look.

cGM Engine (Mirror)

Kain's newest attempt at a Sonic engine has spikes, monitors, rings, Sonic, Knuckles, and Tails, and more. However it is missing a few things such as jump through platforms.


I made mirrors to a few things without permission and if anyone get's mad I'll take them down. I have done this because engines have been known to go MIA and I do not want that to happen anymore. Thanks to everyone that made these great engines. Thanks to DMAshura and RougeYoshi for helping me get all these engines.

Sonic REX Engine

Sonic REX Engine Thread

The Sonic Revival Engine 2.0 (Mirror)

This engine was made on top of one of Dami's older engines similar to the Sonic Revival Engine and is created by Sponick. It probably has more features than any of the other engines including, zoom tubes, swings, moving platforms, Sonic and Tails with Sonic 3 moves, spikes, shields (sonic 3), springs, star posts, 8 way and rotating direction both, and some stuff I'm probably missing. Its really quite a complete engine.


Grid Spatia Indexing (GSI)

GSI is a system made by Damizean that allows you to take objects delete them when they off screen and not in use. GSI is similar to the built in GameMaker deactivation but is much more efficient and can increase performance of your game much more than using GameMaker's deactivation alone. You will find that using GSI is a necessity as levels get bigger and full of more objects that they slow down your game on even some reasonably powered machines. I've included the latest version of GSI along with a example on how to use it below. If you have any questions feel free to ask me (Overbound) as using GSI can be a bit tricky. Keep in mind are if you are using GSI on an object be sure you are not also deactivating it with GameMaker's built in deactivation feature. Second only use GSI on objects that do not move as it detects objects by their coordinates and moving an object makes GSI think it needs to create a new one. Third as GSI deletes objects and then creates them as the come on screen release that the creation code will run again and any variables set before the deactivation will not be saved.

Grid Spatial Indexing 0.15

At the very least you should consider using GSI I know from personal experience that it can increase game speeds by more than 20 FPS.

Damizeans Hydrocity Style 3D Water Example

Just what the title says its a really neat effect. Thanks Dami!

Damizean 3D Water Example

Is there an SNES emulator with sprite layer options? I'd like to rip some backgrounds from The Adventures of Batman and Robin.

Edit: It appears ZSNES does sorry for waisting your time. =P

I'm trying to rip tiles from Ristar and I have very little technical know how when it comes to hacking. I'm using Drx's Feel and ripping tiles using it. It works well with the exception of the background layers which don't seem to be accessible using Feel. Emulators don't seem to be an option either because 1. Only megasis supports turning off layers (I think) and it crashes on my machine, and 2. there are some sort of distortion effects used on most Ristar backgrounds and I don't want the effect to distort the images I would rip. So is there a good method for ripping the backgrounds?

I need maybe 2 or 3 trustworthy people who think they have a good feel for Sonic physics and would be able to spend a little time testing in game physics for me. This means maybe testing out two or more engines until it feels right. Please understand I'm not really looking for someone to go through the actual numerical Sonic physics with me I can do that myself with the physics guide. Anyways Sonic Dash the engine I'm using already uses most of the correct values, yet it still feels off in some ways. Which is why I want testers who have played the Genesis games and really know what they should feel like.

Aim or MSN is a requirement I wish to be able to talk back and forth for a bit, and you will need to be able to play the Sonic Time Twisted demo from last year which you can find in my signature at full speed 60 FPS. If interested you can reply in this thread, pm me, or contact me any of the ways provided on my profile page. Please be an expert I don't want a bunch of noobs trying get a look at time twisted. I can't offer much for the work but you will receive a credit inside the game.

Remember that fan? Remember the sound it makes? I want that sound and I'm having some trouble getting it. It should be simple enough just go to the sound test screen and grab it right? Not really, the trouble is the sound loops in game and I need the sound to loop for it to be useful. I tried opening my favorite audio editing software audition and figuring out how it loops but I just can't get it to loop right I think the sound isn't complete or something. So basically I need this sound and the looped part too. Which means I can only get it in game in Hydrocity itself. The trouble is the music plays interfering with in game recording and I having absolutely no hacking experience have no idea how to turn off the music within the level. So I was hopping someone here would be so kind as to either send me the sound effect with a few loops or send me a rom with Hydrocity Act 1's music turned off. Thanks in advance.
