Two pages ago, someone asked for a CPU with a math-like syntax (or C-style syntax), instead of a "COBOL" like syntax (oops, mixing things up with the other thread). Here it is, my friends: CSR's Kalimba processor . Just look at the assembly code, it really looks like C at times. Not too surprisingly...

That's a bummer. I hope you get better.

You have some fine stuff, but I'm in Canada.

What's up, dude? Your health problems aren't too serious, are they?

I've been having problems with clang builds being crashy. Extra crashy if compiled with -O3, or pgo, but still crashy (and slower than real-time) even at -O0. Mostly in the debugger. A gcc build seems ok. Since this sounds like "compiler bug" I don't even think you're the right person to mention th...

Wait, two C compilers released less than a week apart? What's this, the year of the C compilers? That being said, that's awesome.

I know some members here would like to see some code examples, like what the equivalent of a hand coded memcpy in C looks like in assembly once compiled.

I can't agree more with this. Programming is something you learn by doing it. It really helps when you have some environnement where you can freely experiment and do things that works or that crashes and burns — both are valuable experience. Back in college, I learned assembly (self-taught) on PIC m...

Rounding? What the values look like?

Vim. The first thing I do when using a new IDE is to find a vim plugin. The one in CLion is decent, though I still edit files with vim when using this IDE because there are things it does way better that anything.

Simple question: why is SDL not used on Windows? Is it because it's harder to integrate into window controls? I ask because SDL should be usable on Windows and there would be no need to maintain 2 different rendering codes.

Let's not forget that bit reversing the frame counter can be useful to allow subpixel velocities without having to store the subpixel position, as explained here.

Thus I won't go into detail about it. So much for completeness... I honestly have no idea what you're referring to, so I can't even research on my own. Don't worry, he's just talking about the SO (set overflow) pin that exists on the stock 6502. It's most known as one obscure feature the C64 CBM dr...

What does the 26,06 mhz crystal on the nes motherboard do?

"Everything".

Recently, Chuck Ingerham Peddle, one of the main designer of the 6502, passed away. While he isn't with us anymore, the 6502 and all it enabled at the time (the NES, the Commodore 64, the Atari 2600, the Apple II and a myriad of other computers and video game consoles) will remain forever as a impor...

Different object types, such as moving platforms, like you mentioned, may need different properties, and I handle that by giving each object in the object definition table a "parameter" byte. If 8 bits are enough to represent an object's type's attributes, great, if not, those 8 bits are used to in...

Some Sunsoft games used short triangle bursts like za909 posted. The croaking frogs in Gimmick!, or some sound effects in Fester's Quest, etc. I think Metroid also used it for the "bubble" sound in the Tourian area music. It's not very common, though. Famitracker never supported it (though I dunno ...
