Re: Loading ZX Spectrum 48k BASIC program into NEXT BASIC
I assume so but maybe someone else can confirm that? Yes, you can use RUN AT 0 to 3 as many times as you like, at any points in your program. This goes for asm too, where you can do nextreg 7,0 to 3. The nextreg is also readable, and it is common for programs to read and save the current value, cha...

Re: Changing paper/border colours in LAYER 1,2.
The Next palette system has a pair of 256 entry palettes for every layer. Each entry in a palette can be defined as a RGB333 9bit colour or RGB332 8bit colour (which are actually expanded out to 9bit colours internally after you set them, with the 9th bit coming from oRing two other blue bits togeth...

Re: NEXT FAQ’s
There's an .http dot command written by Remy Sharp that will let you do an HTTP GET or POST on any http address (not https, as the ESP can't do SSL/TLS), and dump the returned results into any consecutive set of 8K RAM banks. It's a bit crude, and only supports a tiny subset of the HTTP protocol, bu...

Re: NEXT FAQ’s
There is no current SMB client, and scant possibility of somebody writing one in the future. The ESP wifi module doesn't expose any useful low level tcp/ip stuff, it's essentially a very flaky modem, running random versions of bad Chinese firmware, running over a slowish serial connection. And the N...

Re: NEXT FAQ’s
I'm pretty sure USB keyboards and mice have to support the PS/2 protocol in order to work with those adapters and I doubt a wireless dongle would bother implementing that (not even sure it'd supply sufficient power if one wanted to) Yep, there was a while back in the early 2000s where manufacturers...

Re: NEXT FAQ’s
If I could figure out a way to map one of the buttons to reset, I'd be laughing. Not possible in the hardware at present, but Allen was thinking of adding a special combination like START+A+B+C for reset. My interim suggestion was to get a smart plug and plug the Next PSU, and hook it up to a smart...

Re: NEXT FAQ’s
Heh yes, I understand. I was more thinking that you could license the code to the Next Team if you owned it, and it would be quite cool to put it to ongoing use. But it sounds like it that wouldn't really fly if your arrangement was informal. And realistically, Garry is capable of writing his own ta...

Re: NEXT FAQ’s
So does it still use the Multiface compression/decompression for Spectrum snapshots or has that been replaced by something smarter ? Snapshots are in .Z80 format to SD card. This is a better choice for the Next than the other popular .SNA format esxDOS uses, as the Z80 format spec allows model and ...

Yes. The June 10th commit at gitlab is ...

Re: NEXT FAQ’s
I did not know this! That's awesome. The yellow NMI button is a multiface "red button". The Next has a fully compatible multiface 1/128/3 built in, and can run with those original Romantic Robot ROMs in the non-Next machine personalities. In the Next, it has a custom Multiface ROM that ca...

Re: Questions about FZX
I think C.Born means that the name DesktopFontEditorFZX.tap implies there is an inbuilt editor, but it's just a set of fonts with a simple demo program. It's just a naming confusion. A lot of the other points are just observations like that, rather than questions or requests for help.

Re: NEXT FAQ’s
Is it possible to save a snapshot of a NEXT game? I know you can use the NMI button to save a snapshot of a running Speccy game but I wondered if it's possible for a NEXT game? No, it's not even technically possible in the hardware, as some of the state like sprites is write-only. Well, it's read/w...

Re: How much self modifying code was there and did it do anything?
Dunno what you mean by that even though I use sjasm lol, can you give an example? Like this. Test label is defined as the address of the 123 operand byte, not the ld a opcode. Test+*: ld a, 123 I don't think it's supported in sjasm, only in sjasmplus. It's in the docs. In zeus it would be this, and...

Re: How much self modifying code was there and did it do anything?
Now thats really hard stuff to stay on top of and I wouldn't know how to do it in a modern language. There's lots of things that are normal in asm (even more so in the older CPUs without memory execution prevention) but which high level languages can't adequately express in first-class language fea...

Re: Next (KS2) joysticks
Thanks Mark. I'll try to bring this back to how it relates to the Next. Normally you wouldn't call the physical wiring between the stick and the DE-9 socket a protocol, just a wiring. But in the case of Sega MegaDrive/Genesis, it kinda is. In the regular Atari type wiring we're all used to, there's ...

The boot options settings (which are indeed a UI for config.ini) are now split into two sections.
