Hi, your BASIC automatically runs the RUN command "AUTO RUN" when it starts. Depending on how BASIC was loaded onto the computer (CMT, QD, FD), BASIC will try to find and run a program named "AUTO RUN" on the same medium. In your case, it would probably try to find and run it from CMT. You can stop this process with SHIFT + ESC. Best regards - Michal

I'm using mz800emu-win64-stable-1.0.8-rev_237 and when I load UNI=BASIC800.mzf (https://old.sharpmz.org/download/universal%20basic.zip), the interpreter loads and then it says: Ready RUN "AUTO RUN" But then, nothing happens and there is no cursor so I can't do anything. The 2.7 version of Universal Basic does work but my source requires v4.

Hi Alex, I'm sorry, but I don't have time to look for ready-made samples or write new demo code for HW scroll right now. But I found an older project at SDCC where I have a simple text terminal in MZ-800 mode — it uses "full screen scroll up" when the cursor is on the last line (cursor coordinates are not part of the code; they are just 2 bytes X/Y). I'm attaching the files scroll.s and scroll.h. Hardware scroll on MZ-800 only works in MZ-800 modes (bitmap 320×200 or 640×200). It is controlled by...

Hi,I am writing now some programs for MZ-800, which use the graphic screen. In the course of this, I decided I want to use the hardware scroll features. Unfortunately the description in Technical Reference manual is quite confusing, so I need some additional info. Do you happen to have something like an assembly listing of a program that uses hardware scroll? Many thanks in advance.Alex.

Hi, From what you describe, I believe you are trying to save your code with the “S” command in the MONITOR 9Z-504M — using this method the program is saved to the virtual CMT in WAV format. The following procedure will work exactly the same from the MONITOR, BASIC, CP/M, or any other MZ-700/800 system that uses CMT: Disable the CMT hack: Menu → CMT → Use CMT Hack Open the virtuál cassette-player window with Alt + C Click the “recording” button, and a prompt will open asking you to create a new PC...

Hello, I tried to update code and carefully abide the difference between virtual CMT mode and CMT hack mode. Now is in virtual CMT implemented CMT engine control via i8255. Improvements are currently only available in SVN (since revision 222). You can try to download the compiled snapshot of revision 222 - https://www.ordoz.com/mz800emu/snapshot/2022-02-09_rev222/ Michal

Can somebody advise where is the BREAK key? And how is SHIFT+BREAK executed?

Hi Alex, I think that mentioned programs using own CMT load/save routines. This means that the CMT hack cannot be used - it is tied to routines from ROM. You must disabe option "Use CMT hack" in CMT menu. After enter LOAD command from BASIC you can open virtual CMT (ALT+c) and insert MZF or WAV and press play. Michal

I cannot make the programs, which start with code 05 to load. Both BASIC interpreters for MZ-700 and MZ-800 work and I can write and run the programs. However directive L from BASIC monitor (Bye command) or LOAD command from BASIC ITSELF does not open any programs - emulator hangs. Is there a solution for this issue?

Guntram Wicke posted a comment on discussion General Discussion
Dear Michal, I am playing with your new release (revision 218), and enjoy again the world of MZ800. Meanwhile I have found the bug in pio8255.c, that troubled me (see my post from February 2021). The problem is, that for CMT, there is neither a "PLAY" nor a "RECORD PLAY" displayed on sreen upon file load or record. Now, a closer look into pio8255.c, line 228, reveals the reason. Line 228 is: g_pio8255.signal_pc03 = value & 0x01; but should be: g_pio8255.signal_pc03 = ( value >> 3 ) & 0x01; If one...

Hi Marek, thank you for the praise, I'm glad you like my emulator. True, the fullscreen mode is not now implemented. Probably just add an event that caught CTRL + ALT + ENTER and called the SDL_SetWindowFullscreen() function - that is easy. However, it would certainly be good to add some sophisticated overlay menu, which would be quite difficult to add to the program. I'm afraid that if the control remained only through hotkeys and existing window menus (not available in the fullscreen mode), users...

Marek Brunda posted a comment on discussion General Discussion
It's a great emulator, for the Sharp MZ800 certainly the best in the world. Thank you for the excellent work. However, wouldn't it be possible to add the fullscreen display option ideally to some keyboard shortcut to make the experience more realistic? I've been using this emulator for a long time and I remember that I once made a quick and dirty change to the source code to run in fullscreen. Unfortunately I already lost it :-)

Terry Johnson posted a comment on discussion General Discussion
Hi Michal, Thank you for alerting me to the Alder emulator, which has the facility to alter the CPU emulation clock speed. My original request was based upon poor memory on my part. It turns out that I own two version of ‘Space Invaders’ on cassette. The version actually called ‘Space Invaders’ works well on your emulator. The version called ‘Alien Invaders’ doesn’t work well on your emulator, but I have since found out that it doesn’t work well on my Sharp Mz80k either. The program is virtually...

Hi Terry, some programs designed for older HW can run on the MZ-800 a little faster... This is due to the different timing between HW MZ-700 and HW MZ-800 (running in MZ-700 mode). Unfortunately, I do not plan to add any slow down features to the current version of the emulator at this moment. I recommend to use the Zdenek Adler's emulator of MZ-800, which already has these functions implemented http://mz-800.xf.cz/download.htm Another option: send me the MZF of this game - may be easier to implement...
-
Great facility, but if I run say 'Space Invaders' then it runs far too fast. Is there any chance that you can offer an option to slow things down? In so far as you already have a 'hook' to implement 'alt/M' this shouldn't, in principle, be too difficult. Preferably this could be achieved by reading in a 'divide' factor from the configuration file. Irrespective thanks for the great software.
-
Hi Guntram, this behavior that you describe is a special (hack) feature that may that might deserve a little better solution. Signal state of CMT motor is in MZ-800 presented in PC4 gate of 8255. Hardware MZ-821 has intergrated controllable casette tape recorder. Motor state is presented as 0 or 1 on PC4 of 8255. Hardware MZ-811 using only external CMT and PC4 is permanently bypassed in "motor running state". Both behavior can be easily emulated, but first versions of mz800emu emulator had integrated...

Dear Michal, I'm back again and tried things with your MZ800 emulator. Now the SDL oddity is solved (thanks), I investigated the behaviour of the CMT and the monitor program, when it enters the file loading routines. I am in MZ800 mode. First thing I recognized is that there is no screen output of PLAY (or RECORD.PLAY) after the monitor loading command L is hit. (Likewise, in BASIC, there is also no output of PLAY.) I think this should happen, as is with the original device. The loading with and...
-
Hi, I think so I know this bug - it is caused inside by SDL in Linux (or somewhere deeper). In this case, there already is no need to modify the source code of the emulator - we have solution in the main menu in the section "Display". Display -> Forced full screen redraving enabled [checkbox] Let me know if it helped you...

Hi chakry, all, I very much enjoy your projectand the vintage world of MZ-800. It was my very first computer. Now the problem and its possible solution. I run both the precompiled 64-bit linux version and my own compiled linux version 1.0.5. In all cases, The SDL windows soon gets bricked. Output is not shown or only partly shown. One can temporarily solve this by resize the window with the mouse. However, repeating this for every output is very annoying. Furthermore,I had to start with locked_window_aspect_ratio...

I added a few options to easy the setting up of those things you mentioned, also I made cmake require you setup a build type, if you want anything else than release. Hope that helps.

Is posible set any own compiler and linker options? For example '-pedantic -Wall'. Sometime I need switch between production '-O2' and development version '-O0 -g', add ElectricFences, etc. What I normally do is change CMAKE_BUILD_TYPE to Debug or Release. You really want to look at cmake-gui to tell you all the options if you are a "graphical" person. QtCreator also gives you all the options in a nice menu and proposes multi config too at first load of a cmake project (release / debug / various...

Hi, latest version is now OK! Is posible set any own compiler and linker options? For example '-pedantic -Wall'. Sometime I need switch between production '-O2' and development version '-O0 -g', add ElectricFences, etc. ad Netbeans: I tryed to create Netbeans project with existing sources managed by cmake. It is posible, but on this new project is not available organisation source files into Netbeans logical folders, or switching betwen project profiles and I dont know if is available full refractorization....
-
I think I found what the issue is with the link failure. because for me everything is in the same location I didn't notice I forgot to add the library location(s) to the imported SDL2::SDL2 target. This should be fixed now. Also I tried netbeans 8.1 and I noticed it understands cmake so that was nice to see and try.

Hi, I found a trap on SDL2 cross compilation. I have compiled my own SDL2 and SDL2 for Mingw. After run 'make install' in native SDL2 is copied sdl2.pc file into /usr/local/lib/pkgconfig/ directory. This path mus be set in environment variable PKG_CONFIG_PATH. After run 'make cross' in Mingw SDL2 is created sdl2-config file - localised into /usr/local/cross-tools/ directory structure. I have now linked this file into /usr/local/bin/i686-w64-mingw32-sdl2-config. Complications lie in i686-w64-mingw32-pkg-config,...

Ok my and my big mouth. Not so easy because of SDL2. On my system SDL2 from mingw did have the .pc file so that was easy enough. I have written a lot of code to make it work if that file is missing. OK, what we are need for compilations: if is target system like Unix, so must be defined -DLINUX for Windows target must be defined -DWINDOWS -DWINDOWS_X86 In the past I've experimented a bit with Win64 (-DWINDOWS_X64), but this is stil for testing only.

Okay, I found that EPEL has cmake3 in it's repositories! I have changed some files to make them compile on centos 7.8 now. Using some docker image I created it now compiles on "centos 7.8" for me. Let me know what you think.

Thanks for looking! My testing: on my PC as first I must change required cmake version to 2.8.12.2 2.8.12 is already 7 years old at this point. And I try to write cmake in the "new" modern cmake style. (>3.0) . Perhaps you could try to use one of the installers from cmake.org if there's no newer version via EPEL (or what is it called these days). All packages reported as unavailable I have available in the pkg-config tool: This is probably due too old cmake, I would need to investigate. Another specialty...

Hi, I got to emulator today... I'm using now Centos 7.8 as development desktop. This system is already a little bit older, but I mean so this is still usable.

Hello, I have organize project on Linux in Netbeans ver. 8.1 because newest versions of Netbeans unfortunately doesn't suit me. Makefile structure is based on Netbeans, but is manually tuned by me. I need this way for cross-compilling, debugging in IDE, for experiments with another libraries, etc. I often switch Netbeans IDE between different platforms whose code is different and often need make tests on Linux and on Windows at the same time. I believe, that other project managers like cmake, etc....
