Features

Gemini 2.02 is a soft for cards with two PIC chips (two 16c84 or 16f84 PIC), with :

• all the usual nordic d2mac channels, including C+ (look at the answer #1 in the FAQ for the exact list of channels),
• auto-update of the TV1000 and TV3 keys,
• user remote updatable keys by entering multimac code, including C+ keys (look at the answer #1 in the FAQ for the exact remote updatable list of keys),
• several switching eurocrypt-m / eurocrypt-s2 modes to try to cope with not auto-switching decoders,
• "on screen-display" of channel ident / key index / switching mode / key(s) bytes in hexa and multimac format,
• hash calculus for ec-m, ec-s2 and triple DES decryption algorithms,
• hash calculus for the ec-m key update algorithm to avoid wrong updates,
• protection against bad code entry : only a wrong key can be updated.

Triple DES

Gemini 2 does triple DES and associated hash calculus to descramble C+. It still works when C+ comes back to the classical ec-s2 algorithm.

Auto-update of TV1000 & TV3 keys

Gemini 2 can automatically catch new tv1000 & tv3 keys. It can even do "cross-update" of keys, i.e update TV1000 keys when you're watching a TV3 channel if Viasat send such updates.

But Gemini 2.02 doesn't contain valid SA and m-keys for the TV1000 and TV3 channels. So, to activate the auto-update, you need to put valid SA/m-keys in it, with the soft newsa.exe (please, don't ask me how to get new SA/m-keys ! I will not answer to such mails).

Remote update

You can manually enter new keys with your remote control.

Gemini accepts new keys in the multimac 3 format. The multimac 3 format is an evolution of the multimac 2 format to allow to enter the 2 keys needed by C+ in 3-DES : when C+ is scrambled in 3-DES, it's using 2 keys A and B. To enter the A key, enter it as if. To enter the B key, add 40 to each number (i.e: if the C+ key index 3 is 4830 2621 4212 3823 2514 7235 2436, and C+ is using key 02 and 03, you must enter it as 4870 2661 4252 3863 2554 7275 2476).

Note :

• for decoders that don't auto-switch ec-m / ec-s2, be sure to be in ec-s2 mode before entering a new C+ key,
• only wrong keys (display with a 'X' in the menu) can be updated.

Eurocrypt-S2 / Eurocrypt-M switching mode

Follow these steps to find the best switching mode for your decoder :

1. If your decoder can auto-switch, you can zap from ec-s channels to ec-m channels without any problem.
   
   
2. If not, test the manual "7777" switch : change from a ec-m channel (ex. TV1000) to a ec-s channel (ex. Canal+). The decoder must display a message like "NO ACCESS" and a scrambled picture. Enter "7777". I hope you can see a clear picture after some seconds.
   
   If the "7777" code works on your decoder, you can prefer the switch "on-channel" mode : enter the "2227" code. Now, the switch occurs automatically, each time you go through a CTV channel (wait until you see a clear CTV picture before changing the channel).
   For example : TV1000 (ec-m) -> MTV (ec-m) - automatic reset - MTV (ec-s) -> C+ (ec-s)
   No more need to enter any "xxx7" codes :-)
   
   
3. If not, go to a ec-s channel (ex. Canal+), enter the "8887" code then remove and re-insert the card. I hope you can see a clear picture now.
   
   
4. If not, then, sorry, I've got no solution :-(
   

Then  :

• If 1 : be happy, you win !
• If 2 : to switch between ec-s/ec-m, simply enter the "7777" code each time or go through a CTV channel if you have activated the switch "on-channel" by entering only once "2227"
• If 3 : the worst case. To switch between ec-s / ec-m, you must enter the "8887" then remove and re-insert the card or switch on / switch off your decoder (perhaps with the remote control) each time

To sum-up :

• 8887 : switch on the following manual reset
• 7777 : switch and reset automatically
• 2227 : set the switch "on-channel" mode (you can still use "8887" and "7777")
• 1117 : set the manual switching mode (need to use "8887" or "7777")

Display

With your remote control, consult the list of available channels (menu "consultation", "control card" or "information") You will see a menu like this :

Instructions

1. Read the info files ! (readme.htm, readme.txt and faq.htm)
   
2. If you've got valid SA/m-keys for tv3 & tv1000, use newsa.exe to put them into the slave file
   
3. Program the master PIC with the file masterb6.h8m (for card with I/O on rb6 pin) or masterb7.h8m (for card with I/O on rb7 pin)
   
4. Program the slave PIC with the file slave.h8m (or slave-2.h8m if you have generate it with newsa.exe)
   
5. To autoupdate the keys for the TV1000 & TV3 channels, stay on these channels and wait (sometime a whole night)
   
6. If you've got a problem, try to send me a log of it (I hope you've got an interface that can log the dialog between the card and the decoder)
   

Changes

Version 2.02 - 990620

• some improvements to work with old nokia/salora/luxor,
• C+ keys update bug fix : with some decoders (for ex: nokia 8003) the two C+ keys were overwriting each other,
• autoupdate fix : for some SA, the autoupdate commands were not catch,
• serial I/O timings changed,
• now, in 3-DES, the two keys are displayed (i.e: "2-3" instead of "e").

Version 2.01a - 990215

• 2 problems with the 2.01 archive fixed : the PIC 16c84 fuses were not correctly set and the 02b50 key was corrupted

Version 2.01 - 990214

• New keys organisation. Now Gemini contains all the updatable TV3 and TV1000 keys in eeprom

Version 2.00 - 990131

• Initial release
