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.

The latest delays...

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...

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...

If you look at the bottom of page 9 in Issue#1 you'll see where the makers of the Human Centipede films got their inspiration from :o

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.
