Random hack/Mini project thread

9 years ago, I attempted to port music from the Master System version of Sonic 2 to Sonic 3 & Knuckles.



It was only partially successful, lacking PSG drums and being in the wrong pitch. It also conflicted with the PSG SFX, breaking their volume envelopes.

Yesterday, I figured that I would have another go at this, this time porting the music to my Sonic 2 Clone Driver v2, which had recently been rewritten in C++. Being written in C++ meant that it would be easier than ever before to add support for the PSG drums. This time, I was able to port all songs, with drums and the correct pitch!



The SMPS2ASM files can be found here.

The ROM can be found here.

 

It would be really cool to hear the original tracks almost unmodified on the Genesis. Just wait and see-

Leaving aside optimism, trying to translate C++ code to assembly language (for current public versions) will be a pain for me and others.

 

They are the original tracks, with the only modification being the removal of an ADSR command at the start of Gimmick Mountain's theme.

I'm not stopping you from porting the original Z80 assembly code instead.

 

Its interesting how did you do that.
Good job! : )

 

Thanks! I wrote a blog post explaining how I did this here.

 

Geez, I remember seeing the original attempt years ago when I came across it (this was before I signed up here on the forums btw), and I’m astounded by this second attempt of yours using the new C++ port of the Clone Driver v2 sound engine to get it sounding as it should. Great stuff!

Here's a tiny thing I did. Seeing how small I can get Sonic 1's file size whilst keeping the core platformer gameplay, badniks, sound, among others. I got it down to 440 kilobytes before stopping there. My goal was to get it down to at least less than 400 kilobytes. Here's what I did:

• Removed Unused Objects, Sprites, Mappings, and Animations
• Removed Unused Code & Subroutines
• Removed HUD, Life Counter
• Removed Title Screen Demo Sequences, Special Stages, Pausing, the Level Select, Debug Mode, the Cheat Codes, and the Continue Screen
• Removed Unused Sounds, Palette Files, and More .bin Files
• Combined "z80_1.bin" and "z80_2.bin" into one file
• Removed the Sega PCM, you'll now only see the Sega logo for two seconds, no jingle
• Removed the Checksum and TMSS routines
• Rewrote and shrunk down the Error Handler
• Removed the ROM Padding & Padding Files
• Applied S3K Monitor Physics (hitting it from below makes it break instead of fall)

Bugs & Side Effects:

• Drums are Lower Pitched (side effect of removing Sega PCM)
• This ROM cannot boot on real hardware due to invalid TMSS (unless you have a cartridge / console mod which removes the check)
• Japanese Credits are Unavailable (side effect of cheat code removals)
• Playing on a Japanese console will make the game unplayable (side effect of cheat code removals)
• Sega Logo is faintly displayed on the "Sonic Team Presents" screen
• Sonic Got Through Title Card is Very Glitched but it works

Go wild with this :b

 

Since you didn't say you had to preserve all of the levels, why not remove everything except GHZ3?

 

You are right now that I think about it. I'll start working on a mini update that strips away every level except GHZ 3, as well as some more tweaks.

 

Hello to all involved. Thank you for playing this rom hack that I am quite frankly not proud of by today's standards.
Unfortunately, I had only made this as a test, out of curiosity of what these programs could do, and I've come to the realization that ROM hacking simply is not for me. If anything, I'd rather pursuit other, better interests that better suit me.
However, I thank you all for finding interest and playing this little test project I did. I will not be continuing work on this project, sadly, but I appreciate your criticisms (even for as harsh as they may have seemed, which I understand why it was done).
That goes out for you too, Giovanni. Thank you for allowing me to reach out and assist me in this project, even if it ultimately lead to nowhere.
Below is a drawing of my gratitude and appreciation for seeing people playing this.

Have a nice day to all of you.

Hi! It looks interesting, but there's a lot of errors.
But appart of that, The game looks nice, that's what i need to say for now.

 

I made a small hack that only edits the msuic by MID2SMPS

Oh and also some music from MDT's TTS Remake is here as well

Rummaging through my old hacks, I found the hack from 2017 that I never published for a few reasons.

I present to you... Broken Sonic 1.

Spoiler: Description

The idea isn't mine, it originates from Razor and Zenon's Broken Knuckles. I just thought it would be fun to do something similar in S1. Also I tried to learn ASM this way (didn't work out).
Concept: you almost can't use the D-pad for character's movement, but you have a few techniques up your sleeve.

Controls:
A and C is a jump. Simple and nice.
B + Down - Spindash.
B - One-time Super Spindash. It's not chargeable, but can be helpful at times.
Sonic almost always has some sort of momentum, so you can stop only by wall or spindash charge. Or you can be lucky
You can change your direction only by charging the Spindash into the wall and pressing left/right or when you do the same in the rolling state (sometimes it works, sometimes it doesn't).

Reasons why it originally never got published?
Never got further than GHZ, so it's poorly tested and a lot of levels don't work with the concept. Level select code is the same as original.
A lot and I mean A LOT of bugs and collision breaks. Guess I messed up some physics (or "S1 moment"), so Super Spindash can break collisions.
And, of course... I thought everybody would call me a copycat for taking idea (haha, CATswell and copyCAT).

So, if you like unhinged challenges, would you dare to try and get through the whole game like this?

Also if you want to take this idea on another level, do it. Just credit me and/or "Razor and Zenon", pretty please.

That's all, I guess? I can't remember people that could help me here, because I almost never even told about this thing. Probably worked on it alone. I'm really sorry if I forgot someone :_C

Spoiler: Side note (it's about SAI)

I'M NOT DEAD AND SAI ISN'T, I PROMISE!!!!
It was a long time ago, I know, but SAI is on hold now due to me working on a smaller project. There won't be any actual news until I get something presentable to show you.
You should know that that hack is getting an overhaul in every aspect though and I hope that you'll be hyped to see the new demo when it comes out

 

Let's enjoy a classic! Sonic the Hedgehog.

Spoiler: Click this spoiler AFTER you've played the game.

This was originally supposed to be released for April Fools, but I have something else planned for that day, and since I had finished this early, I decided to release it now as a mini hack. If you couldn't tell already, this had huge inspiration from the Mario 64 hack "sm64.z64". I tried to pull of the SRAM and the game crashing with the "Something Changed." message but it just wouldn't work, so I scrapped it and opted for something else.

The only credit needed is "The Caretaker" for the music at the end.
If you're gonna make a gameplay video, just call the game "SONIC" as stated in the header.

 

This would have probably won a trophy or 2 if you submitted this to the SHC 2024 or 2025

 

(sorry for double post)
I want to mention I'm going to have a new mini romhack release in a few days similar to the Romhack called "SONIC" called ...

 

Thought I Should post this old Romhack I made a few months ago called Hyper Sonic in Sonic 3 Alone.
The goal was to port Hyper sonic into Sonic 3 Alone.
