Converting an OPOS 1.04 card to Titancard - or OPOS SDK?

[zerofox]

I have a box of OPOS 1.04 cards I'd like to use for projects.

Is it possible to convert these to Titancard2 or another 6464C card type with an SDK available?

Alternatively can someone share the OPOS SDK and loader?

Thanks

Yes, you can convert OPOS 1.04 in Titancard. You need "Toolkit V6 for A90sc Smartcards".

[007.4]

Are people really still using these cards?

I have tried Toolkit V6, but the "OPOS 104 virginiser" doesn't work on these cards. I think the cards may have either been programmed with the old 103 -> 104 upgrader, or started out as 104 cards. Either way, they don't have the erasable 104 OS installed.

I did notice Colibri's TitaniumHack tool could convert from Titanium2 to Opos104 - so an SDK for Titanium2 may work too. From what TitaniumHack does, I get the impression the only differences are encryption keys and header formats.

And yes, people are still using these cards, just for different things. I had some Titan2s in a drawer and these Opos cards came with some Funcards I was using for Hacktv (https://github.com/captainjack64/hacktv).


I have the Opos 104 OS BIN thanks to that kit, if I can figure out the memory map of the 6464 card and where the OS loads, then I may reverse-engineer the Titan2 and OPOS operating systems and build my own AVRGCC-based SDK.
