Re: ZXBrowser

This may occur if emulators are not configured. Check the paths in JSON files and add/remove emulators as you want. Emulators are configured and working, but maybe I'm doing something else wrong (seems so since no one else has complained about this :D). Now I noticed that it works fine when I right...

Very nice work! One issue I found (on Windows 10) was that the download progress bar got stuck even though the download was completed, so I had to force close the window.

Re: Spectrum 2.0 database

Despite that review, in some ways I admired the uniqueness of the game to the extent I submitted a ”sequel” of sorts to the CSSCGC:- https://spectrumcomputing.co.uk/index.php?cat=96&id=31151 Can't believe that was 10 years ago now! Great stuff! There is a potential for a long series here :lol:

I have one and I'm quite happy with it. It works well with my 48K and +2 machines. I've never had any similar device so I can't compare it with anything else though.

Help with diagnosing damage on a +2 PCB

I've just bought a +2 grey from eBay. It has a Z70700 issue 1 board with no modifications that I can see. I will recap it, but I have already tested it connected via RGB. The picture looks quite good, but it sometimes flickers in short bursts, especially when it runs CPU intense stuff it seems. I kn...

Re: I built a game in BASIC

Had a go at it, it's a nice game and very responsive considering it's written in BASIC. I didnt managed to see all the levels but broke into the game so I could see them, along with the victory screen.. :oops: So was it completely written on a Speccy? If so, the discussions about getting it to work...

Re: I built a game in BASIC

Sorry if this was a bit cryptic, but if you add the line I suggested, the program would print 255 in the upper left corner of the screen if my theory is correct and bit 6 is set. It doesn't solve anything though, the emulator should be modified in that case. Still not entirely sure what this is mea...

Re: I built a game in BASIC

I don't know, but it could be the same issue that I had in my emulator, namely that when the keys are polled (beginning at line 170), the value that is matched includes the ear bit (bit 6). If, after loading a tape, bit 6 is set, the keys won't be identified correctly. You could add a line 171 PRIN...

Re: The Definitive Programmer’s Guide to Using the Floating Bus Trick on the ZX Spectrum

Thank you for an excellent guide (and the effort to investigate this issue)!

My emulator now handles the +2A/+3 floating bus correctly I think. Here it is running "Woody’s Special" test (epileptics look away ;)):

Re: Show previous instruction for breakpoint in debugger

And it's a first instruction of some block of code. So I may suspect some JP or CALL was before it. But how can I find it without crazy guessing? Does any emulators stores adresses of executed commands in some log so I could check the log and find a few instructions before my breakpoint? Thanks for...

The next is far from finished, even when the cased units ship work will continue on it. Comparing it to something that's been out for near a couple of years now is a bit silly. I find the comparison interesting, at least while I'm waiting for my Next ;). Anyway, you have a good point concerning the...

Re: ZX Spectrum Next

Thanks for the link. I browsed that thread, but missed that particular discussion. Anyway, I suppose I was a bit naive, but the Next kickstarter could have been more clear on the subject of compatibility. I realise that it probably is no big deal for the vast majority of users.

Cons: Somewhat bad compatibility, and gets worse using HDMI due to timings. A lot ot things don't work or have some glitches (Nirvana engine games, demos with strict timings).

Breakpoints are now created automatically from labels named 'BR1', 'BR2' or 'BR3' (there are only three breakpoints in the debugger). After loading a source file with breakpoint labels, the user has to activate them in the debug window - (I may add an activation button in the assembler window later)...

Re: Emulator integrated with Pasmo assembler

Very nice! Thank you :) Even better would be if you could set execution breakpoints in the emulator using comments in the asm source. I think it would be difficult to set breakpoints using comments in the source as long as I let Pasmo handle the assembly; the emulator never sees the source, and the...
