FPGA is for sub-millisecond devices, not for something hanging off a 31.5KHz serial bus. Technically that's sub-millisecond :cool: MIDI is a 10-bit transmission protocol (8 bit + start + stop, no parity). Each note involves three bytes - event+channel, note, velocity. So, the total time to send a note is 3*10/31250 which is 0.96 ms - very slightly...

CRC media/fat/games/mame/temp/pacman# cksum pacman.5e|awk -F’ ' ‘{print $1}’ | xargs echo “obase=16; $1”|bc 7359FAA1 That's not the CRC32 that it expects. Try to zip it and then use unzip -v to view the CRC. There's also rhash and possibly others. This Python program also calculates it: import sys, zlib def crc32(b): crc = zlib.crc32(b) return crc...

Interesting, you might well be onto something here (thought it's well over my head). But the confusing thing is why do these games work in ao486 and 486 PCem? (from the same hdd image).

With BASIC or BASICA? I don't think either of these works on ao486, because they depend on the BASIC ROM, which is only present in older IBM computers.

pgimeno

-BASIC games remain a big mystery. Despite the problems with keyboard I did manage to test some, and the GW basic games seem to work, but BASICA all end with the "Direct statement..." error. Some more examples (aside from B1 Nuclear Bomber, Baseball) are Big 8 Football, Black1, 15 Puzzle, Acey Deucey. "Direct statement in file"...

Would a 80386 that only operates in real mode be interesting? Implementing protected mode is a heavy lift and DOS doesnt even use it... DOS programs routinely used it. Version 2 of my Spectrum emulator was written to work in protected mode, initially with PMODE/W (a DOS4GW restricted clone) and later with a DPMI host like CWSDPMI, to enter and han...

Have you updated the firmware on the controller?

No, I don't meet the requisites to run the updater. But that line comes from the core anyway. I wonder what makes it trigger. Light gun on/off isn't even an available binding.

pgimeno

I've reverted that commit and update sys to latest. Please test against possible regressions. I don't remember what that change was for. Thanks a lot! When I investigated it, judging by the dates I concluded that this commit was introduced in an attempt to fix issue #4, which didn't fix it but it also caused this new problem. Probably introduced w...

pgimeno

I also use the button as "start" and it works fine. Make sure to map the buttons both on menu core as well as the psx core. Yes, I did that. In fact, at first I thought that I could get rid of the light gun toggle by going to main and remapping the controller, and that it got broken when I went to the core and remapped it there. Later I ...

pgimeno

I have a PS5 controller, which has an extra Mute button. In Main, I have defined the Mute button as the menu button. It works fine in every other core I've tried. However, in the PSX core, sometimes the menu isn't activated when I press it, and instead I get a line that says "Light gun mode is ON" (or OFF). Other times it seems to work fi...

Someone just made the problem worse by pointing to issue #6 instead of issue #4. https://github.com/MiSTer-devel/ZXNext_MISTer/issues/11

Issue #6 is NOT about a problem saving configuration. It's about a problem saving BASIC programs. That mistake will just add to the confusion and reinforce the idea that issue 6 is the same as 4, when it's not.

pgimeno

I don't understand why this fix isn't in the official core. :? Because I left MS Github to not return, and no other person who reads this thread seems to be willing to reopen issue 6 and tell Sorg that he was wrong because it isn't a duplicate of issue 4 , and tell him that the fix is to revert commit e7e7fd56 . So, a question of lack of communica...

Bash is great for these kind of things, and MiSTer has it of course. Here's a short script that does this: mkdir {A..Z} for i in {A..Z} ; do mv "$i"?* "${i,}"?* "$i/" done mkdir -p 1 for i in ??* ; do mv "$i" 1/ done rmdir 1 {A..Z} # remove empty folders It may spit a few errors that can be ignored. This one ...

Aberu, you have a few good points but you even contradict yourself in some others. Sorry for the point-by-point reply but I think it's worth dissecting it. First of all, everyone should have listened to rampa's wishes in the other topic and been respectful. I'm glad some of you decided to take the license debatelord stuff here, thank you for that. ...

pgimeno

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...

pgimeno

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...

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.
