Re: ZX Spectrum Recreated Would Work as Bluetooth Keyboard With MiSTer?

I guess it's time for an update. First, I don't have my two ZX81s because I sent them to a friend for some upgrades. There were screw position and size problems with the ZX Spectrum boards, so I was waiting until I test the ZX81 boards before ordering new ones. The Spectrum ones are supposedly fixed, but the screw positions might still be a bit off...

Re: List of Cores with ADC (Tape Input) and RTC (Real Time Clock) Support

Thanks, I've also updated the status of molekula's other core, the MSX1, which I believe is official for quite some time now and was still listed as unofficial.

Re: PCXT config: mount files/folders

Hi hmc, The PCXT core expects a VHD file that works as a virtual hard drive (hence the name), and/or files that are images of floppy disks. When you have an empty VHD file and/or an empty floppy disk image, it's pretty much as if you have a PC with an unformatted floppy and an unformatted hard disk. Basically you need to start at the same point as ...

As a remainder, it's possible to have up to four different MiSTer.ini files: MiSTer.ini, MiSTer_alt_1.ini, MiSTer_alt_2.ini, MiSTer_alt_3.ini and switch between them using the same menu where you change volume.

Re: ZX Spectrum Recreated Would Work as Bluetooth Keyboard With MiSTer?

Progress report: The software is finished and it appears to be working; I've added a 6KRO standard mode together with my version of the NKRO Recreated mode (see previous post for the differences with the actual Recreated keyboard and the associated issues - but it should work fine with MiSTer). Of course there's the natural ghosting that the matrix...

Re: ZX Spectrum: Rebuilding boot.com

Amazing research work, JamesH! Thanks a lot for filling in all these blanks.

Nice find about Genie 128, I didn't know that one. I wonder if it's a leftover from a time where it was used to debug the core, and when it stopped being needed, only half of it was replaced with another ROM and the other half remained.

Re: PSX Core Stuck at Memory Card Screen

There are some tools to manipulate BIN+CUE files. There's certainly at least one tool (that I've used) to merge disks with multiple bin files into a single bin file, so it's likely that there's one to go in the opposite direction. I haven't looked for it, though, because a simpler option is to convert the dumps to CHD with MAME's chdman, with the a...

Re: ZX Spectrum Recreated Would Work as Bluetooth Keyboard With MiSTer?

I think certain cheats require that. I'd have to look up which ones.

And, well, if it can't pass a keyboard test, it feels less like the original machine. The creators of the Recreated ZX Keyboard considered it important enough as to drive the design of their protocol.

Re: Battletoads

I may be wrong, but I believe that originally, MiSTer had a directory in the root folder for every system where you would put the ROMs, but later, the games/ (or a configurable) directory was created to organize them, yet for compatibility it still searches in the root. In other words, I think that having it in /systemname is equivalent to having i...

Re: Galaxian Update

Thanks for the detailed explanation, macro! I love these kinds of details.

This looks like one of these cases where FPGAzumSpass' technique of making a software emulator with a view on the FPGA implementation before actually implementing it in Verilog could pay off. The compile/test cycle for trial-and-error would be much faster.

Re: Broken Cores

I don't think so, but you can try the following:

  • Upload an existing core with a different name.
  • Connect to your MiSTer via ssh.
  • Use diff -qas <path to 1st core> <path to 2nd core>

The last command will tell you whether they differ.

Re: ZX Spectrum Next's ZX81 Core

It looks like the keys are mapped Spectrum-style, probably by replacing the ROM. For example, shift+ASDFG yields the same STOP NOT STEP TO THEN sequence as in the Speccy, the semicolon is in shift+O instead of shift+X, and so on.

My guess is that they made this to make the keywords and symbols match those printed in the keys of the Next keyboard.
