Demo editing
This is a piece of cake. Change the values to the level you want the demo of. The format is the level number first, then the act number.
| Demo Number | Location |
|---|---|
| Demo 1 | 3C16 to 3C17 |
| Demo 2 | 3C18 to 3C19 |
| Demo 3 | 3C1A to 3C1B |
| Demo 4 | 3C1C to 3C1D |
Codes and keypad editing
The HEX location of debug code is as follows:
- 3B5A-3B5F
For this to be useful you'll need the Mega Drive keypad commands =):
- Up-01
- Down-02
- Left-04
- Right-08
These are two bytes long, so don't ignore the zeros.
- Button A - 00 01
- Button B - 00 02
- Button C - 00 04
- Start Button - 00 08
Now you can have fun changing this strange code around.
Level Select Menu hacking
The hacking here is downright simple. Go to the strings which are presented right below, and then put in the new letters using the letter reference below the string locations:
| Level | Location |
|---|---|
| Green Hill | 3D7C-3D8A |
| Wood Zone | 3DB2-3DBA |
| Metropolis Zone | 3DE8-3DF6 |
| Hill Top Zone | 3E39-3E45 |
| Hidden Palace Zone | 3E6F-3E81 |
| Oil Ocean Zone | 3EA5-3EB2 |
| Dust Hill Zone | 3EDB-3EE8 |
| Casino Night Zone | 3F11-3F21 |
| Chemical Plant Zone | 3F47-3F59 |
| Genocide City Zone | 3F7D-3F8E |
| Neo Green Hill Zone | 3FB3-3FC5 |
| Death Egg Zone | 3FE8-3FF6 |
Now you need to know what the letters are:
| Value | Letter |
|---|---|
| 00 | 0 |
| 01 | 1 |
| 02 | 2 |
| 03 | 3 |
| 04 | 4 |
| 05 | 5 |
| 06 | 6 |
| 07 | 7 |
| 08 | 8 |
| 09 | 9 |
| 0A | $ |
| 0B | - |
| 0C | = |
| 0D | <- |
| 0E | <- |
| 0F | Y |
| 10 | Z |
| 11 | A |
| 12 | B |
| 13 | C |
| 14 | D |
| 15 | E |
