Spectrum Computing

Thank you for this great work @Inky. Is it ok to add a bug report here or is there a more formal way? I have an issue with Kempston mouse support. My Basic program reads out the x/y port values with IN and places the pointer accordingly on the screen. This works well with display scale at 100%, the...

DEC SP/INC SP are silly instructions too. It would be loads better if it decremented/incremented by 2, changing by 1 has no use I can think of, since you always push a word to the stack. If it incremented by 2 it would just be like discarding the value on the top of the stack (I usually use POP AF ...

And looking at the video - yes it's bad. Very slow and jerky. Certainly could have been done better. I had to have a quick nosey :) It could have been sped up a little quite easily. Basically, it seems there's a general reluctance by the coders to unroll any loops. For example, the scroll screen ro...

@StanVanman Let's talk about it next year, once I've had chance to take some things OFF my todo list

Ta! Only the arcade section. Shaun Hollingworth and Pete Harrap did the front end / management section.

I doubt drawing a bigger centre circle would be that much of a drain. (And if it was I'm sure I could live with the smaller one.) It already manages fine with 10 or more players onscreen at once. StanVanman It probably wouldn't have been much of an extra drain. I can't remember why I went with a co...

Brilliant! No problem

It sounds more involved than it is :) Yes, the .gif files will be saved without a border. There's an optional 2nd parameter to inks.save_gif() that controls whether a border is included. By default it isn't, but if you later decide you do want a border, just change the save_gif line to inks.save_gif...

Hi. You can do that with Inkspector’s snippets, which are little Lua scripts. There are 10 of them and each can customised and run with keyboard shortcuts Alt-1 for snippet 1, through to Alt-0 for snippet 10. So to do what you want, fire up Inkspector, go to the Snippets → Edit Snippets menu to brin...

Nah, "docs" is a new innovation for delaying stuff

StanVanman wrote: ↑Thu Oct 26, 2023 11:13 pm Yeah, aren't you meant to be finishing Timeblasters before Christmas?

Oh *that*? Christmas which year? Yeah, I'll be back on it as soon as the next Inkspector release and docs are done.

If I ever complete my current "todo" list of emulator-related stuff, I'd love to do a .pok patch to add Fuller Orator speech to this fab conversion.

Awesome sleuthage! I'm guessing that's a non-trivial fix job :lol: StanVanman Actually, you could try poking 31072,201. This turns the execution of player 1’s score into a RETurn instruction and so prevents all the crazy shenanigans. The instructions that follow this call between $7963 and $796C we...

Curiosity got the better of me, and I fancied taking a couple of new Inkspector debugger features for a test run *ahem*, so I had a look into this. And what I found was not what I expected! When the score is increased to 100,000 points, the code updates the score correctly and no corruption occurs. ...

I was intrigued how the mini game was triggered, so I did a bit of digging and documented it in the Inkspector source code when I was adding the uSpeech emulation: Although all documentation I've seen only mentions the Currah uSpeech is paged in on a memory or port *read* of address 0x38, it seems t...

bugreport Tools > Assemble Clipboard Contents fills skipped space with zero values. In this example right picture shows a large black area of bytes that I was not going to change. Left picture is expected result - two separate areas of changed bytes. Everything is almost good if you do operation 2 ...

When entering a new value in the Poke function, the Poke button doesn't become active. When pressing Enter, the value also isn't changed in memory. https://i.postimg.cc/LJsqhkt3/image.png For now, I used the Write memory function instead. The Poke button is disabled while an RZX recording is being ...

For me it's not impressive. Ghosts'n'Goblins has actually a very ugly, messy code with different routines for everything. I made some research into it one day and my conclusions were the same as given at the link: It's not even an engine. An engine for me is something reusable that you can use with...

it would be great to add at least: "Scale Display 400%" Done. Or the best option would be "User Defined Scale" - by dragging the main emulator window over the edge .. Sort of done :D You can enter a custom scale value. I will look at being able to drag the window too before the ...

I have a problem with Full Screen Mode (GDI render). I can always see a flashing (trembling) vertical line in the middle of the screen (leading from the top to the bottom). My resolution is 2560 x 1440 px. Here you can see, what I am talking about. (if you select 1440p or 1080p). https://www.youtub...

For some future version would be also fine to add a keyboard helper / virtual keyboard, how we can find in Fuse, Spin, Spectaculator, etc. Hi pavero , I will certainly add it to the to-do list. But do you need this because Keyboard Assist (Alt-K) isn't working properly, or for some other reason? Th...

That particular one is called OUTI Time.

Thanks @edjones

https://pic.maxiol.com/images2/1681590751.1346378277.ink.jpg There is still room for improvement in emulation accuracy.. Thanks for marking my work :D I suspect this is the same issue that causes a single column in the Shock megademo on a 128k to show incorrectly (I deliberately broke it in 2.0.4 t...

Hi @Inky , in this new version (2.0.5), when I select one of the Spectrum 128K machines I don't seem to be able move the onscreen menu bar (for Tape Loader, 128 Basic, Calculator, etc) using the up and down arrows. Space works for making a selection, but being unable to move the bar I can only choo...

I'll take a look for 2.0.6.
