I started to test the latest version. First impression: with the new sound chip the sound volume is way down, at the limit of audibility. I have only very few roms which limit the testing possible. You mentioned converting cas to wav, but how do you load them? The addition of a floppy would also allow running CP/M. But only the loading of cas woul...

You can follow that core from here: http://www.retrowiki.es/viewtopic.php?f=109&t=200036887

That's a testing release. New version with corrected timmings and fixes will be posted soon.
Also a testing release for SiDi.

You are right. It does work when selecting Issue3

Hi There.
Latest today's release : https://github.com/MiSTer-devel/ZX-Spectrum_MISTer
ZX-Spectrum_20210403.rbf Release 20210403.

TAP loading from OSD seems to be broken.

Is there anyone else observing the same problem?

Edit: More options stopped working, unusable at all.

I got the wrong thread when answering, but it's the same. I reply here because basically it's talking about the same thing. I don't wish what I'm going to say sounds like sarcasm, but ... when there isn't even an open core of 68030, don't you think the expectations are too high? Forget about the Apollo Team's Vampire, it's a proprietary core and wi...

I don't wish what I'm going to say sounds like sarcasm, but ... when there isn't even an open core of 68030, don't you think the expectations are too high? Forget about the Apollo Team's Vampire, it's a proprietary core and will not be used outside its projects. According to a Finnish colleague, they say the Vampire's core reeks of Coldfire. There ...

After last update ( today ) the C64 core goes black. OSD Works but no C64 Screen nor prompt on screen.
Edit: I realised that now rom is located in /C64/bootrom/c64.rom

Now works fine !

someone remembers the SUSKA board ?

With the 32MB SDRAM + 2MB SRAM module there is no problem with anything.
You mean the 128MB module and SRAM issues ?

Am I going mad?

No, You're not mad.

Very nice, Dragon was my 1st machine but always a cbm guy :) What's compatibility like ?? A FPGA core is not like an emulator, emulation it's a sequence in which some things can run well and others simply do not work. In a FPGA everything runs on same time. If the implementation is good and meets the right timmings, video and audio then what you w...

Bang ! Bingo !

ExCyber , you got the key. Thanks.

After several I / O errors, I realized that from the OSD (which already works) you can configure the options of the machine.
So once I checked it was working and with a DOS 6.2 disk for PC98, this is the result.
I'll take a look, there's a lot to test.

At this moment I am not at my computer, but I remember that it had to do with a video clock.
Something like: CRTC98 : VID | VTIMING : TIM | clk3sft was determined to be a clock but was found without an associated clock assignment.

Sorry, puu san ! Same behaviour and nothing new. I think you've got a problem with video timmings.

I updated MiSTer to the latest version with update.sh earlier, and it became v210103, but it starts normally with the original binary. Just in case, I uploaded a replacement of sys with the latest template core. https://fpga8801.up.seesaa.net/rtl/release-Zet98MiSTer.rbf Thanks puu ! we're close but still not working. Have you updated the MiSTer fr...

It doesn't matter if you have the right BIOS if the core doesn't work. I think that first the core should work without leaving the MiSTer hanging.I know that I am using the correct BIOS but as I have already mentioned, it does not work for anyone and the effects are the same. Until puu can verify that the core works and video is painted on MiSTer a...

Hi Puu Unfortunately the core shows a black screen. In fact I have left it running for a while and it does not load anything. The BIOS is correct and definitely not working. I'm not going to do any more tests because it's a waste of time. The only thing the core shows is the ROM loading progress bar. There is no way to assign disks to the core, so ...

I will test.

Same for me. Exactly the same. But it doesn't start/work.

Ok, I am resynthesizing and I have realized that you have to choose the Zet98MiSTer project. In a while when I finish synthesizing I will tell you if it is specifically this. I was generating a release-Zet98MiSTer.rbf when it is the Zet98MiSTer.rbf to generate. Edit: Unfortunately I have obtained the same result, the behavior is the same. It does n...

I have resynthesized the core and we are the same. No success and too many warnings. It still does not work and the MiSTer hangs completely.

It seems to be a problem with clocks and their allocations/associations.

I have tried the core and only got a beautiful black screen. The MiSTer hangs up and a total reset must be done. I don't know if it's a problem with the ROM or if the core itself has a fault. No OSD present and can't do anything else. Does the video work over HDMI or VGA?, I am not very clear about it, because the MiSTer hangs, maybe it could be a ...

OK. Thank You very much puu.
Let's take a look ! Thanks for your work.

Hi Dave !

What's wrong with the core ?, it does WORK very well !

just need to create a FAT 12/16 image, put inside the Atom stuff and rename to VHD, that's all you have to do.
Thank You for this great port.

Have you tried this core ?
https://github.com/RW-FPGA-devel-Team/Mister_mc-2g-1024

This package is an extension on the FPGA multicomputer, as introduced by Grant Searle. It focuses on the Z80 CP/M computer.

Does work with secondary SD or VHD file as described at git.

This is the latest version I know.
This one works fine.

It's simply wonderful. Thanks a lot.

Regarding joysticks, when I had my Dragon I built a digital to analogue converter to use Atari standard joysticks. I am sure there are Dragon games that play better with analogue but many are Spectrum ports, that I found worked better with normal digital controls, plus my Dragon joystick was like a stick in a bucket! Modern thumbsticks are a dream...

HI !
If you turn OFF turbo, next reboot wil be disabled ( I think so, xD ). To reactivate just turn in on.

CALL SYSTEM
TURBO ON/OFF
CALL BASIC

Just check if your TURBO option in MSXDOS is enabled. With turbo on will load at high speed, then turn TURBO OFF and will load at 1200 bps Remember some games uses: bload"cas:",r load"cas:",r If the program is in binary format, use: BLOAD"CAS:",R If the program is in tokenized BASIC format, use: CLOAD If the program is...
