This is one of those "shut up and take my money" moments. About the extras that could be incorporated into this device. I think the DTV screen modes would be a nice addition. The DTV has a chunky 256 color mode and a blitter. There are some demo's out there that use them already. Oh and yes! the colours in PAL land are a bit lackluster :-( I would love more vibrant colours.

What the PAL palette has going for it is that the colours blend well. This has been used to great effect to produce natural looking images in a lot of demoscene productions, and it was taken advantage of by some games too. With the NTSC palette things look more garish, and that's not necessarily a good thing.

@peshozmiata 3 года назад

This is the perfect project to experiment with as "GPU Upgrade"... Just think of what the C64 could do with features like more hardware sprites and a bigger working palette... The Amiga scene already has modern crazy upgrades like the Vampire accelerators so why not the 64

@squirlmy 3 года назад

@@peshozmiata What struck me is that one of the Commodore's appeals was it's cheapness, and as they become collector's items, upgrading them with expensive parts is less appealing. You could get a C64 Maxi. Or, as far as GPU experiments go, you could use a $5-10 Raspberry Pi Zero to interface with HDMI, maybe using it as a remote terminal, but even that is kind of silly, when you could easily emulate the entire Commodore with VICE with speeds several times faster, on that same Pi Zero, and tweak the emulator software. Also, the later Amigas are 32-bit:.that's a big advance over 8-bit C64s. The Vampire 4 isn't even an accelerator, it's basically a replacement for an Amiga.To me, this has too narrow applications to ever be viable as a mass produced product. It may appeal to you and Adrian, but don't count your chickens...

@peshozmiata 3 года назад

@@squirlmy The retro-computing hobby isn't a practical one, you can easily just emulate any system you like even on a potato rPi and get roughly the same experience. To me the appeal has always been in messing around with old junk more than actually using it to play games and such. The problem with addons like the vampire accelerators is the price, it makes no sense to spend that much money on something that's neither period-authentic, nor comparable to modern all-in-ones in the same price range. If a VIC-II upgrade board would cost around 30-50$ and was designed in a way you could build it yourself, it would be fairly popular.

@mikipank 3 года назад

I'm from Europe, more specifically from Serbia, and I had a C64 in the '80s. At the time, I thought something was wrong with my computer because the colors were “washed out,” and I was jealous of a friend who had an amstrad 464 and who had bright and beautiful colors. Later, dealing with computers, I learned that NTSC C64 also had beautiful and bright colors. Definitely PAL C64 users were in some way "damaged" compared to NTSC users. Great greetings from a regular viewer from Serbia!

@colindragan9352 Год назад

It's great to see new replacements being made for these old chips. As more time passes, the number of still-working originals will only decrease, so it's good to have options for anything not being manufactured today

@fluffycritter 3 года назад

Now that there’s now good FPGA clones of both the VIC-II and the SID, I’d love to see their respective cores get integrated into a single FPGA-based C64-on-a-chip which lets you choose all the different hardware revisions to get the perfect C64 for every game.

@Stoney3K 3 года назад

The PAL colour palette isn't "muted", NTSC colours are comparatively oversaturated. Which was done because of the way PAL and NTSC colours are encoded, with PAL having better colour stability (the same chroma signal gives the same colour every time). That's why NTSC has a tint control which allows you to shift the chroma, and PAL does not. Which means that on European screens, the PAL palette you are showing would be much more vibrant since the CRT's would be adjusted differently.

@sikkepossu 3 года назад

Indeed. I was about to comment that there was something wrong with Adrian's PAL palette because my PAL C64 and multinorm Sony Trinitron video monitor does show PAL palette almost as vibrant as Adrian's NTSC palette.

@CoverMechanic 3 года назад

While you’re correct about PAL being more stable, you’re wrong about the C64 output. The PAL machines do produce more muted colours. Tint has nothing to do with saturation.

@Stoney3K 3 года назад

@@CoverMechanic The point is that because the PAL colour rendition is more stable, the output can be less saturated to reproduce the same colours (by adjusting the CRT to higher color gain). On a multisystem monitor you would notice the difference, but on a PAL only television the colour palette is almost as vibrant as the NTSC one. It's because PAL specifies the colour standard as less saturated compared to NTSC, so "full blue" in PAL standard would be more like 70% blue in NTSC standards. And that is something you would notice particularly in red.

@feicodeboer 3 года назад

If I'm not mistaken PAL and NTSC Tv's use different color gamma curves. I kind of assume this is related to the color differences as well if not the actual reason.

@AmigaOmega 3 года назад

Creatures by Thalamus might be a good game to test. The first level can trigger the VSP bug some later VIC IIs suffer from. On PAL tv's we have a Saturation control to make the colours pop. The challenge was finding the right balance between normal tv and the c64 so you didn't have to adjust it all the time ;)

@Antireality 3 года назад

I never had an issue with Creatures - my C64C is pretty much VSP-safe, but Mayhem in Monsterland could sometimes have scrolling glitches and character corruption if I ran it with an action replay connected so for me that is a worst-case scenario for testing. (Another bonus is the game is fun so it shouldn't be a chore to test:)

Ok so context question: what is Xilinx, and why is it a tear your hair out experience?

@adamsfusion 3 года назад

@@artstrutzenberg7197 The board he used here is a Mojo V3 which uses an FPGA by a company called Xilinx. The FPGA itself is known as the Spartan-6. Unlike most microcontrollers today where you can program them any way you want, FPGAs must ultimately use hyper specific tools from the vendors at the end of the process, and they're... weird. WebPACK ISE is the previous generation of Xilinx's development tools that support chips up to the Spartan-6 and it's just an old environment to work in. It doesn't support SystemVerilog or any of the few niceities added by their latest Vivada tool (the direct successor to WebPACK ISE). EDIT: And the reason they're hair-pulling-out is that they have lots of oddness. You'll get "critical warnings" when working in it that half the time are meaningless, or you'll get a really obscure error that means you should really buffer a clock signal and everything's OK, or something like that. It's just really not friendly sometimes to the point of feeling like it's trying to stop you intentionally :P

But then the chip designer came back to him, and told him that it would leave a huge ugly hole in the middle of the chip, requiring an entire re-layout of the chip to get rid of it. So they decided to leave it in, as the less of worse option. Needless to say, the HAM became one of the killer features of the Amiga... So, as a hardware designer, never assume what software guys will come up with with your hardware features. :)

Very cool, and I appreciate that you actually understand how it works so you review it with sense and thoroughness lacking in all the shill review channels.

Honestly the NTSC version of the 8-bit dance party just sounds better. It is faster and feels look like something you would actually dance to at a party.

The clock in the 6526 CIA chips was sometimes used to seed a pseudo random number generator. Not good enough for crypto work, but good enough for C-64 games. If the 8520 returns something on those registers, that functionality would still work. If it always returns the same thing, the numbers won't be random, as I'm sure you know. Another trick was to set a SID voice to noise and read it, but if the SID was occupied, the software may have needed the CIA and a software PRNG.

I got a similar thing for my 48K Spectrum that enables HDMI, it's the ZX-HD that plugs right in at the back of the machine and it's absolutely fantastic. I also have the DIvMMC that makes it possible to load games from a SD card, no more waiting for the tape to load.
