Spectrum Computing

I was able to compile the 'simple' example by changing to that directory and running the 'build.bat' batch file that is provided which contains this... @echo off cls del simple.tap ..\..\mc simple.txt simple.dat ..\..\fonts\font_zx_spectrum-7.png ..\..\dividers\divider_sin.png ..\..\mackarel patched...

Yep, that looks like a good old-fashioned bug. As a workaround, can you try selecting the "Default" profile on the Keyboard options page and then select "Native Cursor Keys". That should keep you in business until I get chance to fix it. Great that workaround allows the menus to...

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 choose...

polomint If I understand correctly I believe that SpecEmu is coded directly in x86 assembler? which is an incredible feat in itself...in regards to any dodgy code, my virus checker goes crazy whenever I download a new version and I have to rescue the zip from quarantine and make the .exe an excepti...

Phew...glad it's not just me!

Has anybody run this latest version of SpecEmu today? In Spectrum 128K mode instead of the usual menu I got a list of well know virus names to select ILOVEYOU Melissa WannaCry ...and a couple of others and the copyright line began (c) 2022 Stuxnet..... Didn't manage to get a screen shot as for a mom...

Just to whet the appetite...a direct link to a video showing a little of the magic Bob is up to on the 128K machine...

Sleuthing is fun. I did some searching through the roms: Vortex AHMBPUERS LSATT C:CJHORHIN"C which is probably nothing, really. Apparently there are two developer credits, interleaved, in the main CPU at 0x47D8: JOHN LATHBURY CHRIS STAMPER You can probably see that if you rearrange those group...

but then I could use screen paging, not stack copying, to update the display. I've not used screen paging on the 128K before, and wonder if I've been missing a trick. How does it work in practice? Does it make it more tricky in terms of structuring the code? Do you lose the use of addresses from $C...

Hmmm, that would be clever, I'll possibly experiment to see what it would take to try to implement something like this. I guess it explains why so many commercial games opted for using the simpler multiple LDI copy method.

If you choose to keep interrupts enabled, you can sometimes work around the stack corruption by having the IM2 handler back up SP, set it to a safe area, and restore it before exiting. The interrupt routine does save the SP and point it elsewhere before saving registers prior to playing the music. ...

I'm developing a game which uses a scrolling screen area and a back buffer. I want to use an area of 24x24 chars and have been experimenting to see how quickly I can transfer the buffer to the screen. I have a fast method which uses the stack, popping data from the buffer and pushing it to the scree...

One thing that grabs me is that the inertia on this game feels really good for a game of this era. The speeding up and slowing down are well implemented and feel right for this type of game. The main vehicle and enemies continue to move smoothly even when you go near to the side of the screen and th...

Hurray! yes that's it!! thanks [mention]Alessandro[/mention], 'Mask' by Gremlin Graphics https://spectrumcomputing.co.uk/index.php?cat=96&id=3042 So it's not a new game after all, nor from our Eastern European buddies, but a quality looking one nevertheless that I somehow never played back in th...

Thanks for the ideas [mention]R-Tape[/mention] but it's very much a live action rather than strategy type game so not Stonkers or similar games. Just took a look at Komando II which I hadn't seen before and it's got a similar style of look except you drive a jeep or vehicle of some kind around. The ...

I'm desperately trying to identify a spectrum game I watched someone playing live online recently but after an exhaustive search on google and many other places I've not been able to track it down to find out what it is called. Visually it looks a bit like the spectrum versions of jackal/ikari warri...

Yep, thanks [mention]PROSM[/mention] that was indeed the problem. I was on version 9.0 upgraded now to version 19.0 and it handles these RAR file ok now.

I couldn't extract it either using 7Zip. Out of interest I also had the same problem with the CSpect Next emulator which is also packaged as a RAR file so some kind of setting may be being applied when these are compressed, as 7Zip normally has no problem opening such files. In the end I had to use ...
