Re: Cant find the program with digitized music?

Btw, that "Bicie" demo has also one 1-bit beeper tune, but for some reason I can't get sound at all, just border effects. On a real Spectrum (all models), toggling either the MIC or the EAR bit of Port #FE will energize/de-energize the beeper. On 16K/48K Spectrums, it is physically the same pin of ...

Re: Cant find the program with digitized music?

There’s Instrument , a sampler (in TR-DOS format) which has similar sounds. It comes with quite a few demo songs (and clunky navigation, which requires that you swap disks to load the necessary instruments for each song). I don’t think it’s been used extensively outside of demos, though. It’s neat, ...

Re: Creating a compilation game?

Then I guess it would be even simpler to use the original TAP files and Tapir to generate a new WAV file from scratch.

Re: Easiest way to change AY I/O ports in a game?

If I wanted to search for those LD and OUT commands just by PEEKing the RAM, what decimal values would I be looking for? And once I had the decimal address, how would I modify the ports if I just wanted to use POKEs? Because of duality between code and data, you can’t simply use PEEK to find a part...

Re: Game of the day...

Just fired it up. The dogs were there. Never was a big fan of the game, to put it mildly. The intro is very nice, and the graphics are sort of okay-ish (aside from the main character). I like the moving spotlights on the top of the screen to remind you this is a game show . Other than that, I can’t ...

Re: Help repairing my ZX Spectrum+

I think I will have to cut the Z80 legs first, otherwise it will be very tricky. Do you have suggestions or advices ? That seems a bit drastic given that we don’t know if the CPU is dead for sure, but I can understand your apprehension. With care, it is possible to desolder it without cutting the l...

Re: Help repairing my ZX Spectrum+

After a few minutes (at first Reset does nothing), pressing the reset button change the border color !! Yes, but not to white. Does that help to narrow the problem ? I’m kind of suspecting the CPU/ROM now. At this point, I’d replace them with known good parts beginning with the CPU. If you have an ...

Re: Help repairing my ZX Spectrum+

Thanks for making the video. I noticed that if I let the computer powered on for a few minutes, borders start to change colour from white to blue or red, then black... This is curious. Wait until the border changes to something other than white, then press the reset button momentarily. Does the bord...

Well, the reset wires are desoldered and I don't know where exactly to resolder them.
On a Spectrum+, they are typically soldered directly to the leads of C27, which sits across the RESET and GND pins of the CPU.
