The hardware hacker in me approves of this message.

That's why I came here - to have my mind blown

Nice thing running on a sim card

Probably the funniest platform choice of the year so far.

i... sorry what?

(also, how do you even get code loaded and signed on such a card? without lawyers from 3GPP hunting you down, that is)

You need the KIc and KID keys. The easiest way is just to buy a card that is bundled with the key material. I bought mine from Sysmocom (sysmoISIM-SJA2). The actual flashing is a true pain if you need to do it on a real SIM card. It's much more tricky than just installing something on a plain smart card.

Otherwise, you can use an emulator (like the one I made: https://github.com/tomasz-lisowski/swsim) and forward messages to and from the phone using something like SIMtrace2.
Using the emulator would get you a decent framerate, unlike what I had to deal with on real hardware.

P.S. I hoped this would be surprising, so I'm really enjoying all the mild confusion/shock here haha.

AWESOME!

Hum. This was indeed surprising.

I kinda wish the demo itself was more entertaining, but I guess technical limits got in the way.

But whatever, the first release (?) on a platform is always awesome by definition!

yes this is quite cool especially after reading the nfo

Interesting tech hack but as a demo, it's not very interesting. I understand that's because of the platform, but still.

Madness

Yeah, the demo itself is lame, and I wasn't sure if I should release until the end. Eventually I decided that it's hard to do anything reasonable with 15x11 characters in a non-monospaced font (didn't want to make people root to see the demo), in a strange character encoding (not ASCII) from 3GPP TS 23.038. So I just submitted.

It took 90% of the time to figure out how to do this in the first place, so I left too little time to actually think of effects and had to do some all-nighters before the party started xD.

I think the worst part was the frame rate, it basically looked like a slide show in most parts, which made any longer effect look bad. I knew what had to be done to fix this, but the card just didn't let me do that...

It's a platform that can fit on your thumb!

The IC hidden under those 'big' contacts is like a grain of sand haha.

Not that I'm aware of (same goes for any other type of smart card tbh).
This is just unexplored territory.
