Spectrum Computing

Works for me now

I can confirm the issue. The cert seems valid for https://spectrumcomputing.co.uk only. Nothing to do with Google, happens when typing www... directly into the address bar. www.spectrumcomputing.co.uk uses an invalid security certificate. The certificate is only valid for spectrumcomputing.co.uk. Er...

Ha, that actually looks like you're past the "learning Assembly" stage, and are now headed for the "having fun with Assembly" stage

Hmm, "micro", that's something I could get behind, too.
Other than that, "lite" is still my one of my favourites (though it basically was rejected already), and of course [mention]Juan F. Ramirez[/mention]' glorious "16K".

We have a winner.

In other words, it's disabled by default in assembly

Media queries are so 2019 flex-grow/flex-shrink is all the hype now.

Another vote for the v3 banner, btw. In fact I'd like it to be even smaller.

Also +1 to @8BitAG's suggestion. I'm rather allergic to the word "retro". I don't get why you guys don't like word "retro". Personally I have no problem with calling myself and my interests retro, oldschool and vintage ;) And people seem generally to like this words too. Especia...

If anyone has need for music for a custom AY player for which no dedicated editor is available, I will be able to support those in Bintracker soon (in a couple of months). So just get in touch if need arises!

Here's an initial version: https://spectrumcomputing.co.uk/retro/4087 It should work for any game page URL from SC, just replace "entry" with "retro". I know some fields are still missing, don't worry about it, I will take care of these details later. Next step will be adding a ...

Difficult to say without seeing the code. Perhaps you could post it somewhere so people on here can take a look?

+1 to what [mention]akeley[/mention] said. As has been demonstrated countless times in the past, Lee and his clique aren't interested in a rational discussion, so arguing with them is a waste of time. Other than that there's no need to defend yourself [mention]Einar Saukas[/mention], you've done mor...

It's especially helpful in cases like the one you were struggeling with with "and 31" and "first 8K of ROM". The decimal numbers 31 and 8191 tell you nothing. 0x1f and 0x1fff on the other hand immediately let you see that you don't need to worry about the low byte. Or take PeterJ...

"8K" = 8192 bytes. So the first "8K of ROM" means an address between 0 and 8191. 8191 = %11111 11111111, or 0x1fff. We don't need to worry about the lower 8 bits, since they may take any value. The upper 8 bits on the other hand must have a value between 0 - %11111, or 0 - 0x1f, ...

a) does this have bias on larger numbers (ie. if a>=31; AND 31 would always equal 31 ???)? No. A logical AND operates on individual bits. The result of ANDing two bits is 1 if and only if both of the pair of bits are 1. %00110001 (= 49 decimal) AND %00000111 (= 7 decimal) ========================= ...

Thank you @utz. I will need to look at that one written down in binary so I understand! Hehe, I was thinking whether I should give an explanation, but I figured you could work it out on your own. And ideed you immediately had the right idea: Looking at the number in binary will give you the answer ...

Thanks @bob_fossil You made me have a thought. I foolishly forgot that the grey is paper white without the bright. Apologies. I will look at the option you suggest, which would certainly be an improvement. So if I create a random number between 0 and 7 with and 7, then do a bit rotate 3 times would...

A round of appreciation for Einar's z80table! Opening that up is pretty much always my first action when doing any serious Z80 coding.

Ha, you're a machine. Thanks a lot. I think with this setup, only minimal changes will be required on the Bintracker side, as I can send pretty much the same messages that I'm sending to MAME. Just need to write a Tcl script to decode them on ZXEmuT. That'll be fun.

On second thought, it actually doesn't need to work on Windows. MAME will stay the default for Spectrum emulation, with ZXEmuT being an additional option. Windows users will miss out on it then, but well, tough luck :D If you could implement calling Tcl code on hitting breakpoints, that would be awe...

A Tcl interpreter, you say? Excellent! That should be quite workable. I'm controlling MAME through a stdio pipe. I could in theory do sockets, but it needs to work on Windows as well, so pipe is easier to do for me, I believe. One feature that would be great to have is to be able to execute code on ...

Is it possible to control ZXEmuT through stdin? If so, I could actually use it as an alternative to MAME in my Bintracker music editor.

What a waste. That key should be remapped as a second Ctrl key, of course

So no-one indenting for loops, conditional code etc ??? it is not even always possible, considering that jumps can create a fine web. it is much easier (and cleaner, i believe) to split the code to "logical blocks" with empty lines. Exactly, it's not always possible/useful to apply best f...

Ah yes, I studied Zymosis quite extensively when I wrote my own z80 emulation library a few years ago. It's an excellent piece of code. Glad to see you're still working on it.
