What are trying it with?

If you're trying any of the SDK images, you'll have to replace everything in the system folder (except for the scripts folder), with the files from the homebrew CD or Game Guru. My guess is the SDK doesn't include software that will run on a production 3DO.

I was able to get orbatak working by decompiling it, replacing the system files, rebuilding, and signing.

So, it's either the system files or there are multiple copies of the data that need to be signed. Using OperaFS[DE]Compiler strips away the multiple copies of the data. And, if you just replace boot_code, it will hang on the banner screen.

I've been trying the Orbit SDK, (I now see why that didn't work), Orbatak (ditto), and the unencrypted Decathlon.

Maybe Deca has a similar issue. I'll have to test it out again sometime later.

EDIT: I was tired while doing this...

Ok I've tried as many ways as I can. Even took the Game Guru, decompiled & recompiled then tried to sign and it didn't work. Obviously the thing works because you gave am image that did but it's either me or this crappy old laptop I'm forced to work on right now. I'll wait for the finished version.

Are you using:
'3DOEncrypt genromtags isoname.iso'?

OperaFS[DE]Compiler creates a partial rom tags file; 'generomtags' will create one that matches the system files from Game Guru/homebrew release.

Another this is to ensure there is a BannerScreen file in the PARCE_ folder.

Ok I went step by step with the instructions you sent me. Still nothing. Maybe it's this laptop. I'll try again when I get my PC up again.

Anyone else try it out???

I'll see if I can find some time tommorow to give it a try.

Here's a full list of steps:

Here's the english version of OperaFS[DE]Compler:
http://www.mediafire.com/?tm1vjze2mif

Here's the homebrew release:
http://narod.ru/disk/1528979000/3DO_Hom ... 1.rar.html

For orbatak:

Used the decompiler on the homebrew release (or Game Guru) to create PARCE_3DO* (or PARCE_GameGuru*)

Used the decompiler on Orbatak.

To use the decompiler, press the De-compile button (or the left button on the Russian version), and select the ISO. On larger isos, it can take a few minutes. On Vista the X will glow red, when a mouse pointer is over it.

In the PARCE_Orbatak directory, ensure there is a 'BannerScreen' file. If not, you can use the one from the homebrew signing kit or Game Guru/homebrew release.

Go into the System directory is both PARCE_* directories.

Copy every folder from the PARCE_3DO* (or PARCE_GameGuru), except Scripts, to the PARCE_Orbatak* folder.

Compile the ISO using OperaFS[DE]Compiler, this is the Compile button or the button on the right in the Russian version.
When doing this make sure that the PARCE_Orbatak folder is selected, and appears as an open folder. You have to double click on the folder. This was one of my first mistakes when I started messing with OperaFS[DE]Compiler.

If you end up with a large iso, or the program hangs, you haven't double clicked on the PARCE_* folder.

Using the iso from OperaFS[DE]Compiler type:
3DOEncrypt generomtags isoname.iso

The iso is now ready to be tested in FreeDo or burned to a CD.

I didn't even think to ask before...

Is it not running in FreeDo or on a real 3DO?

If it's failing on a 3DO, what speed are you burning the CD at, and with what software?

All my tests have been done with Nero 9 at 8x (which is the slowest I can burn), and I'm using Memorex CDs that I got at Walmart.

No luck here either *sniff*.

I found a bunch of character images inside the disc, check them out here: http://emuconsoleexploitnews.blogspot.c ... -game.html

Btw Cdoty check private messages for a curious question:)

I've seen that before, can't remember what caused it. If you can send me the first 8k of the file, I can see what it's having a problem reading. The genromtags should have fixed any problem with that though.

Let me make sure I have the latest version up. There was a problem where it wasn't writing the new rom tags. I checked the archive, and the source still has the bug in it, I'm not sure about the tool though. I will post an updated version when I get home.

Nice site, by the way.

Post by **3DO Experience** » Tue Jun 29, 2010 11:07 pm

I was using FreeDo, I did get the message from above when doing it step by step. Many other times it didn't stall and went all the way through but the image didn't run.

cdoty · Post by **cdoty** » Wed Jun 30, 2010 1:37 am

I uploaded the latest version. This will definitely write the rom tags.

BryWI · Post by **BryWI** » Wed Jun 30, 2010 5:00 am

looks like the latest version works. I got it too boot up to the banner (nice banner! lol) in freedo but the arcade proto i tried just hung in limbo from there. I'm going to try something else this time.

EDIT: I was able to get orbattak signed and booted. Latest toolkit worked for me. biggest problem is that double click in the compiler. wow, what an easy mistake to make.

Out of interest what software would be needed to write a new game for the 3DO. Do you have to use the mac toolkit software or can software be written in C++ on a PC and compiled to run on the 3DO some how. Excuse my question but I'm not a programmer just asking for a friend who is

Ideally you need the mac software. But mnemonic's homebrew CD allowed you to run his Sonic demo, which was developed without the toolkit. There is source code to the toolkit routines, with a little work a PC toolkit could be created.

You would have to develop your own graphics format, or use some tool to convert into the 3DO formats.

Then again, Basilisk (http://basilisk.cebix.net/) runs well on a modern PC.

What magic did you use to make it work?

I get the same error with 3DOEncrypt.exe no matter what I do.

BryWI · Post by **BryWI** » Wed Jun 30, 2010 3:02 pm

Did you re-download the homebrew toolkit?
http://www.rastersoft.net/3DO/3DOHomebrewSigning.rar
a new one was posted last night. Also I just followed the instructions a couple posts back and it worked.

Thanks for your work on this Charles. This is big step taken for a 3do homebrew scene. I just wish I knew anything about programing. Id like to see a NES emulator on 3do.

Thanks I'll have a rummage through the mac toolkit on my quadra and see what's what.

Couldn't get it running on my 3DO but heres a clip I made using freedo with very crappy sound emulation.

What game is the picture of the mans face from? and I thought Decathlon was released decrypted by oldergames or did they sell it encrypted?.

I stumbled over this linux port of OperaFS that might be of some use to somebody http://www.stack.nl/~svdb/operafs/

Post by **3DO Experience** » Thu Jul 01, 2010 2:46 am

The image with the man's face is a beta version of Killing Time. Decathlon was released, I just did this one from the original unsigned version so it doesn't have that bitch of a flash from the Game Guru on it.

Sweet, I disappear for a long time and come back to see this! Great news! I still have my Basilisk development environment set up, so I will look at cleaning that up and sharing it as a pre-built development environment.

It can nearly be done on a PC. I'm using Arm Developer Suite 1.2, and with a few #pragmas removed, and a new makefile, I can get very close to the program file created by the developer toolkit. The issues I'm having is getting it to create relocatable sections. I get the same result as creating an image with the developer toolkit without the -r armlink option.

The nice thing about ADS 1.2 is that it can use the lib files directly, and only has to have some old #pragma's removed, and the '#ifdef CC_NORCROFT' overridden to always be true.

I tried Arm Developer Toolkit 2.11a and 2.5, which are fairly close to the 3do tools and use the same command line parameters. They have major problems with the headers though. If somehow the headers could work with 2.5, it may be able to build the executable without any problems.

Does the 3DO devkit contain any converter for 3DO fmvs?

There doesn't appear to have been any standard for fmvs on the 3DO back in the day and no converter for any of the formats has been made.

There's a movie convert and a movie edit app. It's not clear what format they take though.
