Kolibri 32x debugger?

T

Tony Hedstrom

I found what appears to be an undocumented (and apparently disabled) debugger in the Kolibri 32x ROM. I was hoping someone with more 68k knowledge than myself might be able to shed some more light on this.

Here is what I've found so far...

Kolibri 32x

Button sequence: Starts at $B5320 (9 bytes long)

Debugger text: Starts at $957D4

Pointers for debugger text: Starts at $95A1D

Here is the debugger text:

WEAPON SELECT: %d...FIELD: %d %s....SOUND NUMBER: %d...-PARAM(C-RESET)-....lower speed: %d....higher speed: %d....startspeed : %d....vjmp accel. : %d....Camera Xpos : %d....Camera Ypos : %d....Slowgame tim: %d....Shield reptim:%d....trn wh. shot: %d....unlimited l.: %d....easy game : %d....Stage reset C+St

Since Kolibri is based on the Ecco the Dolphin engine, I'm guessing that you need to pause the game while the bird is turning (so that he's facing you) to enter the button sequence (just like in Ecco 2).

I've noticed that there are lots of talented people in this forum, so I was hoping someone might be able to look at the ROM and figure out if it's possible to get the debugger up and running, or supply any info that might help me figure it out.

Thanks.

Tony Hedstrom.

Hey, that's very interesting! It reminds me of the hidden menu in Garfield, which I also have no idea on how to access...

Do you know which values are assigned to each button in that sequence? I was just trying to find the codes inside some other ROMs, but I didn't know the button values needed to find them (assuming they're the same in these games).

ICEKnight, here's the info you wanted...

Up = 01

Down = 02

Left = 04

Right = 08

A = 40

B = 10

C = 20

START = 80

That should apply to most Genesis/32x games.

With some games, you can shorten the button sequence by adding a 00FF or FFFF wherever you want it to end. You can do this with a Game Genie code, or by hacking the ROM.

Hmmm... Those are the same codes I was using, but sadly they don't work for Vectorman. Oh well, thanks anyway!

What hidden menu in garfield?

The menu I've never been able to find:

Code: 
Unknown   

3 Button  

6 Button  

Activator  

Mouse    

Team Player 

Level View 

Cinematic 

Music 

SFX 

GFX 

EXIT 

Joy 1 

Play Demo 

Buffer Size

There's also every level/scene name stored in ASCII inside the ROM, I guess those were used in this menu as well.

I haven't been able to find any PAR/GG codes for this game...

I think this might be because it stores the variables in some wierd way, or at least that's what it looked like when I tried to hack the bgm menu. =\

Here's some new stuff I found in the Garfield ROM...

Passwords start at $1462E.

3 bytes for each password, followed by a hex number that

the game uses for that level (different than the numbers

used in the password screen).

3 of these passwords are undocumented (I could only find 4

of the 7 passwords on the internet).

The 3 bytes determine which game character to use for

each slot in the password screen (use the chart below).

The number in parentheses is the level number.

05 04 07 (0A)

07 01 03 (0C)

04 02 05 (0D)

02 04 00 (0F)

03 00 02 (10)

07 04 01 (12)

03 03 00 (14)

Here's the chart that determines which game character

to use for each number:

00 = Cat (Arlene)

01 = Garfield

02 = Boy (Jon)

03 = Dog (Odie)

04 = Bear

05 = Chicken

06 = Mouse

07 = Old Lady (Erma?)

08 = Insect (Termite?)

As you can tell, I don't know the names of all the

characters in the game, but you should be able to

figure out which is which.

Tony.

EDIT: BTW, the RAM address (PAR code) for level select

is FFEE22. Example: FFEE22:000A lets you start on a

different level (not sure which one). PAR codes work on Gens.

Heh, I wish I could have found these before trying every single combination in the password screen. Still, this is some nice info to have, thanks!

Neat! I've tried many different level values and none of them seemed to bring any special menu, sadly. However, there's some "This level under construction" messages I had never been able to find. Here's the list of all the values I've tried at the moment:

An interesting thing to note is that there's a garbled title screen that lets the music end before returning to the SEGA logo, as opposed to the normal title screen that doesn't last for too long and exits to the demo mode. This could be a leftover from the prototype title, although for some reason it uses the same moving objects as the final.

So it looks like the level values were rearranged after the lost levels were removed, as they seem to be in the right order without any gaps between them (there should be at least a gap for Catsablanca's train level).

Now if only it was possible to alter the music value each level uses, perhaps we could at least check if they left some of the lost tunes in there.

For anyone who's interested... someone found out how to activate the Kolibri debugger. I tried it, and it does work. You can get the details from the forums at Eidolon's Inn.
