Some of the devices in the Mega AVR line support external memory. The ATmega640 is an example. Generally you'll only find it on higher pin-count devices which aren't available in DIP packages. If you need something that's a b

GDEMU is for the Dreamcast, but the same person/group also produced Phoebe and Rhea which are similar products for the Saturn. Those don't have a separate home page, but most of the menu entries at the top of the page have separat

Very unlikely that would happen. Sega generally takes a pretty relaxed view to the emulation community and to my knowledge has never pursued anyone for releasing firmware from their systems. He does claim legal and professional risks as his

Just the Costco Energy Shot was 2000% of the US RDA. His total consumption was 2600% if I'm reading his post right. Interestingly, 46mg per day is still well below the value that's generally considered the safe upper limit: 100mg

That demo is rather impressive, but the AVR in an Arduino is much faster than a Z80. This machine is running at ~7.37MHz (which is fast compared to old Z80 based personal computers) whereas the Arduino typically runs at 16Mhz. Further, an i

Both PAL and color NTSC are derived from greyscale television standards and represent luminance a similar way. PAL uses a slightly different encoding scheme for color information that improves on some of the deficiencies of NTSC and uses a

I think the intent is that building something with an FPGA is easier than trying to get the necessary performance out of an AVR with liquid nitrogen assisted overclocking. Obviously, if the Arduino is sufficient without modifications it wil

They've claimed day one Linux support[0], but I think waiting to see if they actually deliver on that is probably prudent. [0] https://www.gamingonlinux.com/articles/htc-vive-plans-linuxs...

MyDP/Slimport adapters typically have a Micro-USB port to allow you to connect a charger, so yes.

This article is not entirely accurate. VDP1 is perfectly capable of rendering half-transparent sprites on top of each other. It was somewhat problematic for 3D games as the drawing algorithm resulted in some overdraw depending on how the qu

That's on source devices, which in this case would be the Pi Zero. AFAIK, sink devices like a TV do not supply power.

That's not the format used by the x86 BCD instructions. x86 (and the 8080 before it) use 4-bit packed BCD so each byte contains two digits (x86 also has instructions for dealing with unpacked BCD, but the digits are still 4-bit). Addit

Two of the open source drivers (radeonsi and nvc0) support OpenGL 4.1 now (though only if you've got a bleeding edge build of Mesa, built against bleeding edge LLVM). This is obviously still pretty far behind, but at least it's ca

Something like the Cubox-i/Hummingboard should do the trick. It has a beefier CPU and a gigabit ethernet interface that isn't attached via USB like the one on the Pi/Pi2.

Nope. An opcode fetch cycle takes 4 clocks, but a normal read or write is only 3.That's why an instruction like LD a, (hl) takes 7 cycles. I believe the GBZ80 always takes 4, but it's more of a separate 8080 clone that borrows fro

It's a direct threaded intrepreter. That code is just looking up the label pointer and stuffing it in the instruction's struct ahead of time.

The G1 hardware supported it (though not very well), but Android had no support until 2.1 which was never officially available for the G1. It wasn't just turned off. Even if you enabled multi-touch in the kernel with a custom ROM, the rest

I bought a G1 back in February 2009 around when Android 1.1 was released and it didn't look "exactly like an iPhone". It didn't support multi-touch, it didn't have an on-screen keyboard and the launcher was quite different in operation from
