You wanted Sonic 1 to be harder? HAW, now you may not even finish GHZ1!
I have made some wonderful Game Genie codes

The horrible truth. Sonic without rings is damn hard, and then the enemies attack, you must be in your spin attack, else your DEAD!

Hint: Don't jump over second bridge!

Okay, and no debug! See if you're the master of Sonic.

I think I'll do that, since I was wanting to play Sonic right now anyway. :P

I got to GHZ act 3.

I made it to Marble Zone Act 1. After that I used save states to keep myself alive. Spring Yard Act 3 and Act 3 are horrible hard

[Kurairyu]

I cabt play as well on the emulator. (because my joypad sucks.) I'd probully do better on a real Genesis.

ARGH! Motobug Madness!! X_X

L0s1, you've replaced all the power-ups and most of the rings in the game with Motobugs!


I have an even more wicked idea, though...replace all the powerups and most of the rings in the game with...Yadrin (the spiky Badnik from Spring Yard)! ;D

I made it to Marble Zone, though I intend to play more.

What about replacing all tha animals with Yadrin. Everytime you kill a Moto Bug or any other enemy, Yadrin will popup and kill you (This can be done with one more Game Genie code) :lol

The original Green Hill should have had that many Motobugs. =

Hmm.. How about making the enemies put one ring when you kill them, and then disabling that invincibility you're given each time you're hit? That would be interesting, as well. =)

I'm downloading a disassembler for M68000 right now. I'm going in for the collision detection routine in the Moto Bug object

This is going to be fun!

Finding the invincibility is kind of hard. The Sonic object is too big for me to understand.

The animal can be replaced with a ring, I think.

If I only could find Dr Ivo's disassembler

[LOst]

Ground detection routine found!

Put a "4E 75" instruction at offset [14E18] in Sonic 1, and no animals, enemies, or rings will find the ground.

Sonic uses another collision detection though.

Hey, I think JonnyUK's "Sonic 2 hard mode" hack gave you less invincibility time after Sonic was hit.
If you know that milliseconds value in Sonic 2 it might be very easy to find it inside the Sonic 1 code, I guess...

I was searching for the Sprite Status Table with Google, to find out how to manipulate the sprite, such as "number of hits to destroy" and "how to destroy".

I found this document:
http://swpat.ffii.or...xt/ep/1241/657/

This is fucking Yuji Naka's and Masanobu Yamamoto's patent document of the Sonic engine :shock:

WOW. That's an interesting thing to read... 0_o

So Naka even patented the kind of animations that happen when Sonic and Tails are running on those corkscrew roads..? Or could that mean something different?

Yuji's going to sue the creators of Halo. :P
