Spectrum Computing

EdToo , pavero Thank you very much! I want to share something that was explained in the presentation of the game only in Spanish but I forgot to mention in English, so I apologize: There are two Morse code hidden words in two of the songs/loops that are played along the game . One of them is quite ...

Thanks Andre Leao for showing a preview!! Dear all, Happy New Year 2023! hope you all the best this new year. We manage to publish our third ZX Spectrum game in 2022. The name is "The Void Bringer. The Backrooms: Level 711". A ZX Spectrum 128k game. As usual all for free: https://furillopr...

No-one had any thoughts on this one? I loved the aesthetic, and the gameplay was unique, if simple. As someone who can't do combos in fighting games at all, it was nice to have the arrows printed out for me to follow. I achieved Nirvana without too much difficulty. ( And also in the game. ) This is...

Dear all, thanks for the good words. If you find something strange, like an unexpected bug or something that does not work well please let me know. Be well and best regards!

To make the barrier to entry even lower, you may wish to consider a javascript based emulator on a web page. Good point! but that requires more than one file, downloading a zip containing the navigator, etc. It is not embedded into a single .exe file (which is for instance more useful for people wi...

[mention]Andre Leao[/mention] , thank you for your follow-up, my friend! :) Dear all, the application above is a Windows .exe file for Windows 10 or a recent Windows version (it will not work with Windows XP, Vista or 7). A single file including an emulator and our complete collection of 48k games i...

Dear all, just a quick message to confirm that we finally had time to publish the tool and files required to use the Japanese feature with the MK1 engine :D . Files and a guide are at this link: https://github.com/Iadvd/RetrocomputingZXSpectrum/tree/master/GameExamples/MisakiDemo/MK1_Tool To the for...

[mention]akeley[/mention] thank you, glad you like it!! yes, one week, except the new tool to convert to hiragana: that one was made in 2020 and took me around 1 week to think about it and make it. Cheers! :) This game was made in one week? Seriously? Wow. I think it's quite wonderful, especially lo...

[mention]Lethargeek[/mention] hey thanks for your support, it is really important the feedback. Regarding MK1, MK2 and MK3, this game "Yopparai Sarariiman" is quite special, we just had one week to prepare it and we wanted to show the hiragana features, so it was not our best moment / oppo...

[mention]TMD2003[/mention] yes, as you see it is possible, but tricky. The Hiragana set of characters requires more characters of 8 bytes each to be stored than our A-Z letters, for that reason if you want to store that set you need to use not only the a-z characters set storing place but the A-Z pl...

Dear all, we hope you like this game! We made a new tool for the MK1 engine in order to be able to write games with in-game texts in Japanese language (Hiragana, using a self made conversion of the classic Famicom 8-bit Misaki font), so this is game is intended as an example of use. It is also a &qu...

Thanks [mention]Andre Leao[/mention] , waiting anxiously for your in deep review. P.S. there is also a Jukebox .tap file including all the music tracks of the game all for free, give it a chance:

Cheers and have fun!

[mention]1024MAK[/mention] Thank you I will try next weekend. By the way, I forgot to mention that I bought another issue 2, and this one has the speaker working, so I will measure both and compare them. I'll be back.

[mention]1024MAK[/mention] Thank you, :) regarding D13, if faulty it should affect to the mic output... And I can hear clearly all sounds through the mic output with my headsets (keyboard clicks, loading sounds, music...)... so whatever is wrong it seems to be another component or the pcb circuitry ...

[mention]1024MAK[/mention] Hi! I am back with the results. It worked! I changed the two faulty chips ic15 and ic21 and the 48k memory is back!! The image is stable, memory ok... But still the speaker does not work :( This is the current picture: https://raw.githubusercontent.com/Iadvd/Retrocomputing...

The diodes in the issue two are D9, D10 and D13. D9 and D10 are near to the loud speaker (do please check the wire connections to the speaker). D13 is near the ear socket. Does this board / machine still LOAD from tape okay? Does it SAVE to tape okay? Note to the admin/moderators, if you want to mo...

[mention]1024MAK[/mention] hi again! This is very curious because right now I have the same problem with my issue 2 (you kindly helped me a week ago, remember?) So far I have changed first the 9v>5v converter and still the speaker worked (i.e. press a command and the click sound happens) then I chan...

[mention]1024MAK[/mention] Hello! I have purchased the memories... TMS4164-15NL. They will be here in one month or so. Meanwhile I will change de dc converter/regulator and the capacitors along this week. I will be back with the results as soon as I finish. Cheers! :) So, any TMS4164 chip rated at 2...

[mention]1024MAK[/mention] Hello, today I had time to take the pics! :) First, the "jail bars" ... they appear when I set the vr's in the best possible white color position: https://raw.githubusercontent.com/Iadvd/RetrocomputingZXSpectrum/master/etc/speccyrepair6.JPG When I take the pics i...

[mention]1024MAK[/mention] I am connecting to an Android tablet via a USB image capturer, my other Spectrums have a clear image using this device, so the problem really seems to be the quality of this specific machine. And yes I have the "jail bars" always! indeed, the best clear whitish i...

[mention]MrClump[/mention] Thanks yes, indeed Retro Revival was my first option, but right now Retro Revival main page says "Non-UK customers: Apologies, but I am currently not shipping outside of the UK". I also checked their eBay site and same message... (you have probably guesses, my li...

[mention]1024MAK[/mention] Hi again, first of all thank you very much for all the time you take for helping! ok, the results: I have checked all the positions you asked and all seems pretty well, of course still the image is very unstable, not accurate, blurry and with background noise, would a reca...

[mention]1024MAK[/mention] Thanks for the explanation regarding the voltages... I am going to try today to check those and will be back here with the results :) During fault finding and servicing, I recommend the following tests. Test the voltages on the 7805 voltage regulator and report the results...

[mention]1024MAK[/mention] Hi, thank you very much for the explanation of the design, uncle Clive is amazing. :lol: Yeah it is my case that the colors are unstable so I touched also the adjustable/variable capacitors. Touching a little bit made the image closer to something acceptable. But anyway, i...

Ok here are the results... by touching the trimmers / potentiometers, the colors get more as expected but just when it is going to get the best white color (for instance testing with the Sinclair copyright welcome image white background) then the image turns unstable. Curiously, then touching a litt...
