atari falcon DSP programmer help?
 

Hello to all!

I happen to be looking for help from people that have been implied in atari falcon programming (particularly DSP code) in order to help us with our ordeal at atariage:

We would very much like assistance in bypassing the very nasty protection system of a game called "crown of creation" in order for it to be dumped and playable through disk files (before the originals fail) on emulators like hatari...

Might anyone be interested in helping to preserve the legacy of the falcon?

How does the copy protection work? is it disk based?

Sure...love to help. Please provide me with a nice Falcon - preferably upgraded t o 14mb and 060 cpu.

:lol

yes it is! seems copies of originals and previous imaging techniques didn't cut it! the program asks for the original disks to be inserted...

Are all the files on the disks visible, or is it a custom loading format?

I'm not sure, I'd have to take that up with macfalcon at the atari-forum boards.

It's a normal filesystem. The problem is it's a combined 030 + DSP56k protection, i.e if you remove the first one (manual word check), everything seems to be fine and then, out of nowhere, the game reboots for example because some checksum doesn't match in DSP.

Hatari (an emulator) can run this game, contains both 030 and DSP debuggers, but it's not an easy task.

Galahad? What's your point of view on this?

Send me the disk images and i'll take a look.

Sounds interesting enough to finally use the Falcon I bought years ago for the first time. :) I'd like to have a copy of the game too to have a look.

OK, I've got someone from the atari board who is willing to send images. I'll get those here asap.

thanks guys!

Well it seems that macfalcon has had a few problems with jaymsa in order to image the disks: seems disk 3 is turning up an error (may have to do with the protection system!
However, a preinstalled version along with manual and cover scans is coming!

Hi there!

Just asking: does anyone have news on this?
is the file I supplied enough (they aren't perfect disk images but I hope they are still workable)...

thank you for your imput.

I can supply you with a hdd version (installed game).

What *is* the legacy of the Falcon??

one from www.atari-forum.com made a copy of disk #2, still available, here.

galahad? stingray? have you had any news regarding this lately?
