Re: ZX Spectrum Next Discussion
@Bizzley so are you a backer of either the ZX Spectrum Next or of the Vega+? Mark I'm a Spectrum Next backer, backer No. 3034, standard £175+£10 boxed version. I wasn't originally going to back it since I have no real need for a Spectrum with all the versions I have in the attic but got involved in...

Re: ZX Spectrum Next Discussion
As others have said crowdfunding is a risk and you do have to accept that you are not guaranteed anything. It's just the way it works. 99% of the time it works fine. Just sad that the 1% happened to us. According to Kickstarter themselves 9% of projects that are funded and have succesfully created ...

Re: ZX Spectrum Next Discussion
The only thing that disappointed me is the lack of ULAplus, and only from "political" issues. Also, it's supposedly fully open source, but when the sources were released a couple of months ago... the VHDL code of the FPGA core is mysteriously missing. And the lack of additional cores, tha...

Re: ZX Spectrum Next Discussion
I think crowd-funding started out with noble intentions but as soon as people realised the lack of accountability involved they saw how they could take advantage of it. I don't mean they planned to take the money and run right from the start (but apparently some did!) but that the whole "you're...

Re: ZX Spectrum Next Discussion

Re: ZX Spectrum Next Discussion
[Is this asking questions about when it's out? Maybe they're not quite sure and don't want to keep promising dates and never delivering. They have had some setbacks. I'm not sure when asking for something as basic as a rough give-or-take-a-few-months date for delivery of an almost completed item be...

Re: ZX Spectrum Next Discussion
If you want to point out a certain subset of problems that the Vega+ had that the Spectrum Next hasn't then I can't stop you. I agree with you, the two points about stock footage and trolls fortunately have not afflicted the Spectrum Next but I think you have to agree that there are other similariti...

Re: ZX Spectrum Next Discussion
I expect they will start to ship end of Jan or so I'm guessing based on progress so far. I genuinely wish I had your optimism and all I ask is that the backers be told what is going on. If they want to say the thing won't ship until July 2018 then OK, I may not like it but I'll accept it and bide m...

ZX Spectrum Next Discussion
I started this Thread because of a meme I posted recently about the ZX Spectrum Next computer and the comments that followed. I don't think it's fair to people who only want a laugh and don't care too much about the Next to fill up that Thread hence this one. If anyone has anything good or bad to sa...

Re: Spectrum memes
Hehe. Looks like the Next's honeymoon period is over :mrgreen: There is a slow, growing, disquiet about this project which is not being helped by the ethos currently held by the people developing it that their end goal seems to be absolute perfection rather than actual useability. The latest delays...

Re: Mario Kart
And of course there's the controller: Turn Left, Turn Right, Brake, Accelerate, Use Item and Drift/Hop - those are the most important ones which you'd need if you wanted the proper feel of the game even though the original maps a few more functions on to other buttons. That would be fun to implement...

Re: Mario Kart
Hi. I've been thinking (not for the first time) how realistic is the idea of a Mario Kart style game on the Speccy? If you're talking fast, true 3D then not realistic at all. You could compromise by making it a 2D top-down view a-la super Sprint or one of the similar Codemaster titles, you might ev...

Andrew and Philip tell the story behind Super Robin Hood themselves at www.youtube.com/watch?v=UTwQ-qmJ07c . The Spectrum conversion was carried out by Mark Baldock as stated in the video and in other sources. Fun Fact. The twins needed a retail copy of Spectrum Super Robin Hood when they were putti...

Re: unsigned to ascii
Here's a very simple and small z80 routine to add two five digit numbers held as ASCII strings together using string addition rather than 16bit conversion. It's generalised in that it will add any five digit "number" to another with a resultant less than 99999 but can be optimized by reduc...

Re: Game art copied from elsewhere
By the way, does anyone know how the artists copied the art in a predigital age? Did they use a pantograph to produce a sketch, then paint over it? In my experience they just started drawing on the Spectrum screen, usually with Melbourne Draw, without any aids. Seeing Mark Jones accurately draw out...

You can take anything out of context if you try hard enough.

Re: Speccy help needed!
Have a look on eBay, RCA phono to HDMI cables go for around £3.50, converter boxes for around £7. Whether they work or not I can't say but for £3.50 it's got to be worth a punt.

Re: Creating an eBook. I know it's not retro, but, can't think of anywhere else to ask the question!!
MOBI files can be viewed on what is basically a Kindle emulator for all supported models to make sure everything displays properly without having to spend a penny on hardware. It's the official Amazon Kindle Previewer and can be downloaded for free at : https://www.amazon.com/gp/feature.html?ie=UTF8...
