Re: Steinberg Avalon cartridge

I'm Swedish. In Sweden it's legal to reverse engineer for the purpose of compatibility. My expressed purpose is to be able to run legal dumps of original disks in emulators.

Re: Steinberg Avalon cartridge

Red dongle (Cubase v3, Cubase Score, Cubase Audio) on the way thanks to Evil/DHS. Some reading about reverse engineering an LFSR here ('B' protection being one bit in, one bit out tends to support that alternative), in cases where the seed/key lengths are reasonably small: https://github.com/bertran...

Re: Steinberg Avalon cartridge

Routine "A" (black dongle) we are working on: Synthworks Wavestation 1.14 Avalon 2.1 Cubase 2.01 Routine "B" (red dongle): Cubase 3.10 Cubase Score 2.0r6 Judging from PCBs/ICs I think Twenty Four (http://www.computinghistory.org.uk/det/21930/Twenty-Four/) and Roland Tentrax (developed by Steinberg,...

Re: Steinberg Avalon cartridge

There might also be different hardware dongles, even though they're all Steinberg. From this thread we know that Synthworks and Avalon use the same method, only different variables and equations. From a thread on Atari-Forum (down, so reading cached) I saw Frank saying the Cubase Score one is differ...

Re: Steinberg Avalon cartridge

I have a question about the cartridge key. Does the software have a s/n or does it access hardware thru a midi port. There were not many ways to validate a dongle in the old days. Some of the old dongle looked for something unique like a code from a startup phrase in a booklet or stored the phrase ...

Re: Steinberg Avalon cartridge

Having already successfully reverse-engineered the equations of a PAL, I have quite detailed ideas how I would proceed. With enough effort it should be possible to reconstruct the equations. Too bad that these dongles are very expensive on eBay; too expensive to do this as a fun project. (I have no...

Re: Steinberg Avalon cartridge

Speaking of reversed... No offense but... IIRC one time my brother inserted the dongle upside down, it got hot but fortunately it recovered from this... So I need to ask...: is it possible that you put the dongle upside down? Tomorrow I will check the Gnd-Vcc resistance on mine Yeah I do think that...

Re: Steinberg Avalon cartridge

Now you have a fried dongle, so at least they were right about the fact that they are not eternal, but still... I'm really sorry for you :( Just a hickup, but irritating. It does give me some incentive to in addition to emulator support also try to produce either a working GAL16V8 replacement or, i...

Re: Steinberg Avalon cartridge

This is all sounding very positive! If it would help - I have Synthworks dongles for the Yamaha DX & Korg M1 (as well as Cubase 3 & Avalon) so I might be able to set them up with my synths & compare operation with & without a dongle? It may take a period of time to get the results but happy to help...

Re: Steinberg Avalon cartridge

Unfortunately this excercise has come to a screeching halt :( After seeing your program produce 64 0's (except after 4000 and 8000 which were 8) I suddenly realized I haven't actually tried starting Avalon on the real STE with the cartridge plugged in. "No key found" Turning the computer off and rem...
