How can I edit the text ZONE in Sonic 2?

You can edit the word "ZONE" for both Sonic 1 and 2 using E.S.E.

http://projectnemesis.ibforums.com/esrael

 

The word "ZONE" is located at $CB0F-$CB24 in Sonic 1. The format works like this:

0004F805<font color=#008800>004E</font>E0

Header - tells you how many letters there are in this grouping.
Vertical positional byte - don't change this.
Letter reference in mapping format - the first byte is usually 05, although for the letter I it's 01, and 00 for a blank space.
Horizontal positioning byte - this may need fiddling for aesthetics.

The letter shown above is the Z in ZONE.

Now you need a letter guide for the second section of the green area. The good news is that the first byte is always 00. The second byte changes thusly...

00 = A
04 = B
09 = C
0C = D
10 = E
14 = F
18 = G
1C = H
20 = I
22 = K
26 = L
2A = M
2E = N
32 = O
36 = P
3A = R
3E = S
42 = T
46 = U
4A = Y
4E = Z
56 = ( blank )

(All information from Esrael's guides.)

 

I noticed that after I posted and fell asleep before I could edit. Sonic 2 is easier.

All data is correct and verified, I checked myself in my own hex editor.

Are you talking about this?

 

:lol:

At $147BA, there is an offset index for all level names in the game (2 bytes for a level).
The text ZONE come after the last level name.

$14BC8-14BEA
ZONE string.
The first 00 04 is a 2 byte header, that's the number of characters the string has.

 

Butbutbutbutbutbutbutbutbut... I got the above info from Saxman's guides! D:

 

Hum... <_<
Saxman guide of June 11 2004:

Level Splash Startup

(...)(To make the post smaller)

FORMAT:
#1 #2 #3 #4 #5 #6 #7 #8

1 - Y position of the character every pixel
2 - Length (going by the character size bytes gives a corrected length)
3 - Graphics every 256 8x8 sprites
4 - Graphics every 8x8 sprite
5 - ???
6 - ???
7 - ???
8 - X position of the character every pixel
(...)

0147BA - 2 bytes for location after this location for each level

Here is how each string is listed.

Level 00

Level 10
"Zone"

Now, you need to know what value to give each character. Here are the values.

80 - E
84 - N
88 - O
8C - Z
DE - Character list (see "Level Splash Startup" above)

For quick referencing, here are some of the string locations.
