A quick look at the datasheet for the tiny13A tells me that having CKSEL0 and CKSEL1 both set to 0 (as in ticked, according to your screenshot) switches the chip's clock source to external. Without a clock source input on SCK (pin 7), the chip will appear to be bricked. This can be fixed without usi...

When I tried out Waifu2x, it took 3 minutes to finish on a CPU, and 6 seconds to finish on a GPU. I'm curious as to what CPU you're running. Depending on the image and magnification factor my 8c/16t Ryzen 1700x can be anywhere from a few seconds up-to a minute, but my use case for Waifu2x is nearly...

"Shadowing" and "mirroring" are terms used by different subcultures of retrocomputing for the same phenomenon: two different sets of addresses to which a circuit that responds identically. While true for 'mirroring', I've always known 'shadowing' to be the act of copying a set of data and then usin...

All this talk of lag with emulators vs FPGA vs original HW fail to take into account one thing (unless I've missed it): Not all inputs on (most) display devices are treated equally... Unless you game exclusively on monitors. Ignoring emulators for a moment, lets just compare PLD based re-implementat...

If the game actually uses NES game logic, that would be interesting, but I'm not sure how one could sensibly make the game play precisely like the NES version unless one were to have objects either become active only after they've fully scrolled onto the screen, or cease to be active before they re...

I actually learned a new fact about the C64 from this: Apparently the Super Mario port uses "VSP", a hardware quirk that allows you to scroll the entire screen, just like on the NES, by incrementing / decrementing the 3-bit scroll on an exactly timed cycle outside the visible screen. I can imagine ...

Just to be the second person to mention ReactOS :wink: , the latest alpha version that was released late last month is now capable of hosting it's own build environment. ReactOS can now build ReactOS... Apparently it could in the past, but that was when the kernel was full of hacks to make things wo...

I like the idea of the RetroTINK-2X, but seeing that the device handles composite and S-Video then the lack of any means of adjusting colour (and tint for you NTSC folks) kind of dulls the appeal of it to me... that and the creator's attitude towards some things. As in, during a YT interview he was ...

Why destroy a YI cart when the sd2snes now has full SFX compatibility? :wink: Seriously though, I wouldn't destroy another cart to do this. Just Google for a 128K sram sop 32, just make sure you get a 5V part. They can still be had relatively cheap and you'd be using a brand new part rather than ris...

so Mayhem being in front on pink and blue, but behind green, brown and yellow My understanding of C64 sprite / background priorities is that for multicolour characters sprites will always have priority over colour 01 while the background priority bit affects colours 10 and 11. Carefully drawn GFX w...

@Hojo_norem: It's true that you can't have more than 8 sprites per scanline, but you can make them appear as having a wider coverage circumstantially with strategic placement. fighter_spriteboxes1.png I agree that you can make larger meta-sprites by spreading out the hard-sprites, but that still do...

Could you cite video timestamps of parts of that C64 game that can't be done practically in, say, a Tiny Toon Adventures game on an NES or Master System? The technique of layering a hires outline sprite over a multicolor sprite is clever, but it's aesthetically roughly the same as the face layering...

That makes more sense... it's also not what the c64 wiki says here The C64 wiki is wrong. Here's a quote from the C64 Programmer's Reference Guide: MULTI-COLOR BIT MAP MODE Like multi-color mode characters, multi-color bit map mode allows you to display up to four different colors in each 8 by 8 se...

The thing to note is with architectures like the C64 and chipmem only Amiga, video bandwidth is ultimately constrained by how much CPU bandwidth you are willing to steal. Of course, the large advantage of such a design is the ability to randomly access the memory the video hardware is currently addr...

p is the musical symbol for piano or soft. f is the musical symbol for forte or loud. The software-defined volume envelope of NES pulse and noise channels is versatile enough to allow sound drivers on NES to play soft, loud, or anywhere in between. Ah, right. Makes sense. I suppose you just have to...
