Savegame File Structure

[hotdog003]

I've taken the liberty of getting out my hex editor, Hexplorer, and hacking the save game files for SRB2. This is how far I've gotten.
NOTE: All numbers are in HEXADECIMAL.

_/_/_/ SRB2 SAVE GAME FILE STRUCTURE _/_/_/

Bytes 0-17:	Player Name

Byte 2a: 	Map Number

Byte 34:	Chaos Emeralds (This works by the bit.
00000001 would be 1 emerald,
00000011 (03) would be 2,
00000111 (07) would be 3, and so on. The table continues like this:
00001111 (0F) 4
00011111 (1F) 5
00111111 (3F) 6
01111111 (7F) all 7
11111111 (FF) 8, if you want them.

Bytes 45e-45f:	Number Of Lives

Byte 456:	Color

Byte 457:	Character (0=Sonic, 1=Tails, 2=Knuckles)

Bytes 458-45b:	Score (In Hex, ex 98 53=21400)

Byte 462:	Number Of Continues

EDIT: Oops! 34, not 32.

Awesome. 8)

Heh heh. Since FISHBAKE is taken out of 1.09, you can cheat this way!

Okay, I'll just cipher the savegames a bit, too.

 

[Zash]

why is everyone trying to cheat? :|

 

[ST218]

We're really just trying to sqeak every last ounce of replay value out of 1.08, because 1.09 is looking to be quite far off.

Heh... SSNTails' Emerald trick worked, then? Cool. I didn't think it would, being that the first savegame hack I made had all 8 emeralds and a yellow Sonic. I wonder how long it'll be until you guys figure out how to get the PSO items from an SPMoves save.

 

[hotdog003]

How did the emerald thing work, anyway? From what I can tell, it goes like a curve something like this, but I'm not sure:

.....................| - 7 emeralds
.....................| - 6 emeralds
....................|. - 5 emeralds
................../... - 4 emeralds
.............../...... - 3 emeralds
.........../.......... - 2 emrealds
....../............... - 1 emeralds
/..................... - Nothing

01 - - - - - - - 7F

 

[JTE]

It works by the bit, not the byte like you are looking at. Sneaky.

!
THanks!!!!!!!
GRRRRRR!!!!!
HOW COME I DIDN"T SEE THAT?????
I'll fix it rightaway.
I suppose 8 would be FF, right?

 

[JTE]

Yep. That's also how they do the badges in Pokemon games. Why do you think there's always 8?

 

[hotdog003]

I don't play pokemon games, so I wouldn't know...

 

[JTE]

Well, there's a lot of other non-related games that use the number "8" for non-sequencial collectables. I just don't play video games much unless I need inspiration.
