Let's not lose sight of what the real issue here is. Some people offered their code under the condition that if it is used, the GPL freedoms must be granted. That code is incorporated into every core for MiSTer, and in most cases it just can't work without it (or without a non-GPL replacement that is not yet written). Neglecting to comply with thei...

You can use incompatible software licenses together as long as you have the author's permission. Yes, but all of the authors. In the PDP-11 core case, Rampa only got permission from the PDP module's author, not from the framework's authors. The issue applying a software license to files that describe hardware is another issue altogether and I do...

Could you tell us where the reference to Amstrad is in your repositories or emulators? I'm complying with Amstrad's requisites for permission by not altering any copyrights in the ROM that I'm distributing. "[W]e appreciate it if..." does not state a requisite, so I don't have an obligation to reference Amstrad. Anyway, please keep looki...

I want to think that omitting me from the template contributors was a mistake..... I don't have to ask. I didn't omit anyone; I listed the ones I saw in the first page of commits and added "and others", as that was enough to make my point. I didn't know you're a contributor; if you're a copyright holder, that's great, as that's one less ...

Again I don't understand what the framework is in this context, The framework is the sys/ subdirectory from this repository: https://github.com/MiSTer-devel/Template_MiSTer It's the code that provides cores with a uniform menu with options, with the possibility to communicate with the main executable for receiving ROMs, disks, inputs and whatnot, ...

This is not about receiving permission to use the PDP code, it's about receiving permission to use the framework. The framework is licensed under the GPL and contains code from Sorgelig, wickerwaka, Robert Peip, zakk4223, matijaerceg, skooterblog, paulb-nl, Jotego, Grabulosaure and others (see https://github.com/MiSTer-devel/Template_MiSTer/commits...

Don't take me wrong, I've been wishing for a PDP-11 core for a long time - even tried to make this Russian clone work but I had serious stability problems for me that I couldn't solve. I'd be really happy to use it. But if betraying the spirit of free software is the means to have it, then thanks, but no, thanks. And this thread is the correct plac...

License:

The copyrights to the VHDL described on this core are held by Sytse Van Slooten. In short, you are allowed to run the core for personal use, but you can not use it commercially.

Isn't it using the GPL'd framework? If so, the whole work falls under the GPL, which explicitly prohibits imposing further restrictions.

Thanks. WinWorldPC is an excellent site for abandonware and I use it for OSes and programs. I completely forgot it had a game section. :lol: I was just there a few minutes ago for Turbo Pascal. V3 is tiny (1x360K floppy) and fast but lacks in libraries. V6 is the last version supporting PC/XT and can also run/generate code for 286 (5x360K floppies...

I use the PS2 with uLaunchELF's embedded file browser to copy saves from the memory card to a USB stick. It's more involved because they are individual saves, not full memory card dumps, so you have to find a way to update the block with the directory as well, but that works for me.

Hangul is spc800han.rom which I have no idea where to find. Mame expects it but it's not online anywhere.

It's included in spc800.zip in the MAME merged romset.

Quite often, the undocumented flags are used by mistake. For example, Ghosts'n'Goblins for the Speccy won't work if an undocumented flag is not properly emulated, due to a program bug. And some protection schemes depend on the behaviour of undocumented flags as well, in an attempt to fool those who attempt to debug them (and won't work if they aren...

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.

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...

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...
