Talking about EHZ boss, Sonic 2 Final:

$2F290
Change 06 to 08, Robotnik main ship will went straight up instead of diagonal right.
$2F28A
Change 04 to 02, same thing as previous, but more faster.

$2F286
X position to end the Robotnik main ship movement at start.
$2F2BC
Y position to end the Robotnik main ship movement at start.
$2F608
X position where the car stop, waiting Robotnik at start.
Change it to an upper value, this will delete the car during battle, keeping wheels and the screw!
$2F698
X position where the first wheel stop, waiting Robotnik at start.
$2F6A8
Same thing for the second wheel.
$2F6BA
Same thing for the third wheel.
$2F808
X position where the screw stop, waiting Robotnik at start.

Hehehe...

Hey Sonic Hachelle-Bee! It's me, from the SSRG! You'll be pleased to know I'm actually using those offsets in my hack!

BTW, have you ever thought of making a hacking guide? You are pretty talented. Have you got any info on the other bosses?

Thanks.
Actually, almost nobody knows it but I'm really starting to write one hacking guide for advanced hackers under Sonic 2, to make special features under this game. This HTML guide, with links, a table of contents, index... is very long to write, and it's difficult for me to write all the informations (in English!) my scrapbook contains! :lol:

EDIT: My hack takes me a lot of time too...

Look out, Nemesis...

[Hayate]

LOL. Well, I find Nemesis' guide rather confusing.

[Mustapha]

SHB - Are you willing to include some of my boss information?

I have found the locations for Sonic 2 and Knuckles (a SMD converted to binary using Esrael's Sonic Editor II)

$328A46 - Replace the "7000" with "4E75"
$3288ED - Replace "0002 001C" with "0000 000C"

There may be some bugs associated with this method, try to find them :P

In spite of the fact that S2&K is just a quick 'n' dirty combination of S2 and S&K, it's cool to see that someone cares enough about it to open it in a hex editor and do some poking around, even if they're just looking for something from S2 in there. Nice work.

Actually. Quick and dirty is not the real truth though. It's a whole new Sonic 2 version. Actually the last version I have seen being developed. With no scroll bug in EHZ and with that cool title screen, I must say I have been inspired of it a lot.
If there is a Sonic game I would dream about having the whole source code for, it would be that game.
With all the data, and with Sonic and Tails enabled, it would be the most complete Sonic 2 out there.

It isn't a hack like all those ROMs you'll get with SMC and SMC+. It's actually built from the source. It got a soul!

That's right.

The UPMEM of S2&K contains all the game, and it's a bit different compared to the original S2.
There is this EHZ scroll bug, but also the level select code "01 09 09 04 01 00 01 08":
Under S2 final, 00 is used to end a code.
Under S2&K, it's FF, because 00 is used for the debug code.
Under my hack, the debug mode of S2&K Long Version won't work properly because of this.

Talking about bosses, all sprites are under the UPMEM, as well as raster effects, start positions, level order, pallets, rotating pallets, pattern load cue's, some sprites placement, and others... There is almost everything, except the art data and almost every sprite placements (under S2) and Knuckles sprite with some data about the end of game sprite (under S&K).
So yes, this is like another S2 version.

And it is the last version of the Sonic 1 engine ever compiled for the Motorola 68000. The Sonic 1 engine was used in Sonic 1, 2, and Sonic CD... Even though Sonic CD was way different in data handling.
