How were operating systems of old phones written? Pure asm? C with asm? Is source code available anywhere?
hardware specific assembly code
Something like pic related, pretty sure C (with some ASM of course for kernel etc)
Always C or some higher level languages. No one writes anything remotely big in pure assembly. That's what compilers are for.

Not that I don't agree with you, but this fucker was written in ASM
>Old phones operating systems
How new are you? Old phones were only used for phone calls and messages
>>51829284
But they still had an operating system.
>>51829222
It's common in embedded systems to figure out where your code spends most of its time and then write those portions in assembly. For a lot of architectures the standard tools still emit assembly language that is worse than what you can do by hand.
>>51829284
and in what way is that related to the questing in what language their operating systems were programmed ?
>>51829280
No. There are C functions in rct to interact with directx and windows drivers.

>Being this fucking retarded
Tell me anon, what is an OS
>>51829222
a nokia like the pic in OP would be written in just assembly, it's not a large enough program to need to use C

>he doesn't know about libraries for S60!
>>51829280
Wasn't Z written in ASM aswell?
Iirc games magazines used that as an argument why it ran so great on old hardware.
>>51829284
what about snake? that's a game right there.
>>51829858
i'd love to see its source code
So would there be any way to possibly get into one of these phones and maybe get some code or files off it or anything?
>>51830131
I would. Like many programmers, I made a snake clone many, many years ago and I would love to see how mine compares to theirs.
Flip phones ran on Java for some reason. You could actually get, like, Sonic the Hedgehog and stuff if you knew where to look.
>>51829280
I would seriously consider doing small games as assembly exercises because of RCT.

Correction: I'm seriously considering
>>51829858
Oh man, when I got a color screen Nokia I was pretty devastated that they didn't have Snake on it.
