Wow, I did not expect an answer so soon! Do you know how long ago that was? Not much. https://github.com/MiSTer-devel/Arcade-DonkeyKong_MiSTer/pull/39 I took the existing core, which had a single sample for the walk, and added two more and made them play cyclically, per requests in this thread. I'm not very interested in the original DK sound beca...

Also, I am not sure what happened between 2004 and the time it arrived in the MiST repository, and where the mra files come from. I have not tried very hard to ask around, but if anyone who knows reads this... I took these samples from an old MAME sample set, from the time when MAME used samples instead of simulating the analogue sounds. I think I...

The filesystem is already mounted with the sync flag; isn't that script redundant?

There's a version for the Speccy as well.

I think cathrynmataga was talking about this unofficial one: viewtopic.php?p=39223#p39223

To add another piece on the "input lag vs display lag" puzzle, or why monitor lag can feel like input lag: note that you're reacting to the screen you see, that actually happened in past, because what you're seeing is delayed. So you're reacting to an old frame, not to the current frame. Even if the input is immediate, you won't see the e...

Would it work to have an SMS core in _Console and a GG MGL file in _Handheld?

If you have files in both the SD card and the external drive, you can always add a symbolic link to access the latter, like this: ln -s /media/usb0/games/Archie /media/fat/games/Archie/external where 'external' is the name of the folder that will appear in the SD card list of files, that will let you access the external drive folder; of course you ...

Thanks so much Flandango. I've checked it and indeed the French BASIC ROM recognizes an AZERTY keyboard which is what Malaespera asked.

Congratulations, the tap loader works great. As an additional feature you would consider adding switching between qwerty and azerty keyboards. Unfortunately the ROMs are built-in. Given that there's a good bunch of them in different languages, making them loadable via the menu would be a plus. It would also avoid potential copyright issues with th...

Is cycle accuracy beyond 4.77 MHz really important? I mean, 4.77 MHz was the frequency of the original PC. Many authors adapted the speed of their programs to the speed they experienced in that computer, like they did in many other computers until that time, where basically all PCs, like all Spectrums, all C64s, all MSXs, etc. ran at the same speed...

Unfortunately no, I can't. I've left GitHub.

Correction in the next version. Thanks!

There was no info in the readme. Do I just rename the bios to boot.rom and put it in games/coleco ? That's how it works for me. It's pretty usual to work that way, because that's how Mister Main provides BIOS files to cores, so I suggest to try before asking next time. There are some exceptions: cores that allow you to choose the BIOS from the men...

Two keys to the right of L, there's the apostrophe '; to get the double quote you need to press LEFT shift and apostrophe.

Don't ask me why it works with left shift only.

On the other hand, I attach the VHD specification document, in case you find it useful: https://go.microsoft.com/fwlink/p/?linkid=137171 I'm pretty sure that the VHD format that MiSTer uses is a raw disk image and not in VirtualPC VHD image format. As such, there's no data about number of sectors per track, number of heads or number of cylinders; ...

Thanks a lot LamerDeluxe! It's a relief that this was merged. And again I have a hard time understanding Sorgelig's position. He seemed very adamant to insist that people with a non-US keyboard should use the US layout despite the keys not matching how they are labelled - why then should it be a problem for him to understand that people can use a k...

I've now read Sorg's other reply. I keep both a PC keyboard and a Recreated keyboard connected through USB; the hub has room for both and it's not a problem, I keep the Recreated behind the normal one while not in use (there's room between the PC keyboard and the monitor) and I switch them depending on the core. Similarly I have three controllers c...

Clutters the code? The Recreated code is clearly delimited, it doesn't cause any confusion with non-Recreated code. Part of what was done is a cleanup of the somewhat fishy pre-existing keyboard code. It actually reduces clutter. The ghosting commit was not kept separate in the PR from the Recreated support commit. That may have caused some confusi...

Here it is (the regular core, not the composite one) with the latest framework changes and the rebased patch. Not sure what's new, but apparently the VGA_DISABLE thing was part of that update.

AmintaMister wrote: ↑Tue Nov 01, 2022 12:27 pm If you want, I can propose the patch via GitHub pull request with my Gituhb account, let me know!

If you have git skills, sure. I've uploaded the patch to https://codeberg.org/pgimeno/ZX-Spectru ... created-zx to make it simpler.

It seems I missed another sys update. I'll recompile with it ASAP.

Same thing but with the VGA_DISABLE line set to 0. Please give it a try as well. If this doesn't work then I'll give up for now because I have no idea how to compile the files. You may be luckier by submitting my patch to that repo and asking the author if it can be included as part of the Spectrum build.

- The per-frame cycle count is 71136 instead of the expected 71364 in most PAL machines. That corresponds to 312x228 (lines x cycles per line) instead of the 313x228 it should be. Hopefully this will be an easy fix. I looked at VDP interupt. The number of cycles can probably be adjusted relatively well. Looks like there's a missing one line in the...

Hi @pgimeno, I've found a ZX Spectrum Recreated Keyboard at last and it work beautifully with your patch. One question: can you also update the latest versione of the MikeS1 core (https://github.com/MikeS11/MiSTerFPGA_YC_Encoder)? Because to use the Zx Spectrum both in composite and with the rubber keyboard would be a dream! Glad you're enjoying i...

Given that Minimig comes from a different FPGA, I'd say that studying that implementation is a better idea than focusing on ao486's. My understanding is that in MiSTer, you have to communicate with the Linux side via the HPS_IO to read or write data from VHD image files. I still don't know how that works, but there are plenty of cores that do this ...

Since the .vhd cannot be written, does that mean there is no way to, for instance, save BASIC programs, or save games that have save game features, unless I use a secondary SD? As for saving BASIC programs, check this thread: https://misterfpga.org/viewtopic.php?t=2645 I think the issue reported there persists. There's a fixed core for download in...

I suspect that the reason why the 601 error occurs at 14mhz is the timeout (CX=0) caused by the Loop instruction. That makes full sense. I expected issues of that kind with the frequency switch. It's the same reason some Turbo Pascal programs stopped working on faster machines: they had a loop that they didn't expect to ever finish but it overflow...

Comparing two compilations will give different results for sure; the compilation involves random numbers for some tasks. Only if the random seed is the same, can you obtain two identical compilations. I don't even know how to get or set the seed, though. Spanish company Dinamic made a clone of this arcade for the ZX Spectrum (edit: and also for Com...

Update: I misremembered, it wasn't the dummy ROM, it was the Dr. Mario + Puzzle League ROM the one I had as boot1.rom.

Also, in the GBA core boot1.rom is no longer loading at start for some reason. Was support dropped?

Directory names starting with an underscore are visible in the menu; the rest don't show up. For example, _Arcade/cores and _Arcade/mame are not visible in the menu, but _Arcade/_alternatives is.
