Spectrum Computing

In my journeys learning assembly for the Speccy, most times I've used "wait for any key" code I saw in examples. This one: waitKey: xor a in a,(254) cpl ; as bits are high by default, invert all bits and 31 ; 00011111 Mask off top 3 bits, as only interested in rest jr z,waitKey And I've se...

It says It includes PTx player ..

Thanks. That's the version 7 I already use.

Thanks for replying.

Where could these be found?

For my projects, I've been using pt3player.asm version 7 from Sergei Bulba's website. Is there perhaps a more recent version available somewhere? Perhaps faster? I saw that v7 anticipates also older pt3 files, which I don't really need. Are there versions of the player code that are specific for the...

As far as I know, it was being worked on but not merged into an actual release. You're much better off with one of the other emulators that support ULAplus. For more info on emulators with ULAplus and other info, you could join the official ULAplus Facebook group here: https://www.facebook.com/group...

class... any immunity or infinite lives pokes? I found Infinite lives: 37596,0. Poking 61077 with the number of lives you'd like to start with is also possible, but anything above 6 will display funky artefacts on the screen, as it tries to display the number of eggs accordingly. Didn't bother with...

Where did you get this info?

OK, there’s currently the following ways to attach and configure peripherals in Inkspector: Via Options→Peripherals (1) Specifies the peripherals to attach to the emulated machines. These changes are remembered between Inkspector sessions. Via Options→Peripherals (2) Specifies the peripherals to at...

You can hot-patch the Kempston from the Machine->Hot Peripheral Patching->Kempston Joystick Interface Thank you for replying. I see, it was this that I understood wrong. In other emulators, when changing it in the options, it's effective immediately. Is there a reason to have the Hot Peripheral Pat...

Yes, the ULAplus editor is fabulous. I suggested a few tweaks to Lanex that he implemented. The only thing needed to make it really useful for end-users is the ability to export a palette loader as shown on this page https://sinclair.wiki.zxnet.co.uk/wiki/ULAplus under Palette file format . Then the...

I'm currently helping develop a game in which I'd like to detect if a Kempston joystick (interface) is present or not. The code I'm using (which I've nicked from Starquake) is: isKempstonPresent: ld b,0 .kempstonPortTestLp: ld a,224 out (31),a in a,(31) and 224 ret nz djnz .kempstonPortTestLp ret Wh...

Could you please tell me where are you from? What city? Perhaps I could use your city name to distinguish you from the other Andy Green, instead of "Andy Green [2]". Might solve it now, but what if you do that for all Andy Greens and they live/move to the same city? With the current data ...

I contacted Andy and asked if he could have a look at the thread.

ZX-Spin has a quite good ULAplus palette editor.

I've made an overview of all Windows emulators that support ULAplus and how to turn the option on, if needed.
It's in the ULAplus facebook groups file section, but I also put it temporarily here:https://www.dropbox.com/s/00kv6xnrzk3ch ... 9.pdf?dl=0

You'll find the documentation on Github interesting

The loader is set up to activate ULAplus, load the palette and then initiate a LOAD "" for the actual program/game to load where you'd like the palette to be applied in. In emulators, in general, you need to disable options like "auto load tap files" because they clear memory bef...

A very impressive engine, Denis. Great work.


And thank you so much for sharing the source, very generous

Thank you for letting me know, @Luzie

Yay! Really happy with the conditional breakpoints and also the command parser doc

Already put copymem to use to fill the screen with pixels by copying from 0. And the asm command is also extremely handy.

Thank you Mark

I think there might be very useful commands for debugging in that function.

Hello,

Does someone know if a reference for the possible commands in the Command Parser exist?

TIA

Are you looking for this tool ?
I don't know how it works, haven't tested it.

Thanks, it seems so. I'll have a look at it.

Hi, A new game in development by Team Moritz just -needs- a guitar sample (or two). I read that Gasman created something called wav2ay by I seem to be unable to find info on it, and the util itself (for Windows). Would you happen to know about other methods to convert an existing sound and play it b...

I wonder if you could do with LD HL,16384 and LD DE,16384-32 ...
