Nice player. I also made a vgm player (it plays a lot of adlib formats) but it is not 100% working with VGMS, and it is a lot simpler than this. Just in case people wants to try: https://github.com/mills32/Adplug-for-8088-86 I think you misunderstand my intended purpose for MyMenu... It's not really a music player. It is launcher/menu (that suppor...

Ok, so today I've created a 512MB hard disk with 1024 cylinders in 86Box, I've made Fdisk on it with Compaq Dos 3.31 - the only 3.3x Dos that supports partitions of 521MB. I've formatted, made "sys c:", then copied the content of the 3 floppy disks Compaq 3.31 Dos to C:\, then copied the new mymenu.exe for PCXT in mymenu folder together ...

So going through the INI file, it seems like we need to remove the TURBO options so only the "slow" one remains? # TURBO=Full - 486; $A100 # TURBO=Med - 286/386; $A1A0 TURBO=Slow - XT 8088; $A1A1 Or would it be enough to just have this? You can still # out those "TURBO" options to disable the feature entirely, however, After do...

But that requires Long file name Fat32, isn't it? It needs a LFN driver otherwise it is limited to 11 chars for directory names when LFN is disabled. DOSLFN is not compatible with XT computers, however, LFNDOS can be used. I have corrected some keyboard issues when running on the PCXT core and translated the UI drawing privatives into assembly (fa...

This has important implications, especially in relation to serdrive , if we ever use it with this BIOS , as the use of floppy and PC booters could be sufficient in principle, and for the rest, use Tandy 1000 : I was also considering that, however, I'd also guess that the XTIDE BIOS probably is aware of the FIFO in a 16550 UART so was not quite sur...

In PCXT, keyboard input was buffered in the shift register. However, in PCJr, the data signal is input directly to 8255. If we want to implement it in MisterPCXT... we will need to create a converter. It seems like it would take a lot of work, maybe in the future it could be assessed. We would only gain another small catalogue of PCjr exclusive Ta...

Keyboard - The IBM PCjr.'s keyboard is basically compatible with the PCs, although not as easy to use due to the fewer keys and the chiclet arrangement. However, with Fn key combinations it is possible to generate all the keystrokes of the PC keyboard. The Tandy 1000's keyboard interface came from the less-than-PC compatible Tandy 2000, and while ...

Greetings, I decided to assemble a floppy disk image with some benchmarks on it... It comes with my "UISYSCTL.EXE" which allows the various performance options to be quickly set using mouse/keyboard/joystick: uisysctl.png The benchmark menu uses "JCHOICE.EXE" (which is simply a replacement for DOS CHOICE) that allows using mouse...

@flynnsbit - Is it possible to add additional games to an already created TDL collection? I have a TDL setup with a bunch of games, but want to add some other games that aren't part of that original collection. You can easily add you games under LaunchBox (which is a secondary launcher)... It is not straight forward to add games manually to the TD...

Does the ScummVM installer add anything to user-startup.sh? (MiSTer) ScummVM does not install anything outside the ScummVM directory with the exception being launch Scripts. To remove ScummVM completely from MiSTer (assuming you installed it to the default location) issue the command: rm -rf /media/fat/ScummVM /media/fat/Scripts/ScummVM_* What doe...

What about the midi? Could a midi synthesizer be implemented in FPGA, so an external device is not required? I am not aware of any midi synthesizer implemented in FPGA... Do you know of one? (Also, since we now have an actual OPL3 in PCXT, would ao486 benefit from replacing the Z80 by it? Is Z80 still needed for other things?) https://misterfpga.o...

Curious how you did this. If I edit the sh file I can only change SCUMMVM_HOME_DIR, which would impact where the ScummVM files are located, right? How would I just point the games folder to my NAS? SCUMMVM_HOME_DIR specifies where the scummvm bin and libs are installed. You don't need to change it. ScummVM games can be located anywhere you want. W...

How does the midi hookup to the Mac plus? Is it through the serial port? It might just work if I add the midi settings. I haven’t tried it. The serial compatibility is much better now. This would seem to suggest serial(from the Roland Sound Canvas SC-88pro manual): The PC-1 settings are 31.25K (bit/sec) and the PC-2 settings are 38.4K (bit/sec). S...

- On one game title screen, hit Return, then enter aattddtt119922..116688..00..111166 (replace numbers with IP address of second MiSTer). Note you have to enter every letter twice, I don't know why. Make sure you see the full aattddtt... string on the bottom row of the title screen. For me, there was often a little rocket symbol first before the l...

I got a qn though, I can't seem to get general midi to sound right on my mt32pi when i select the appropriate sc55 soundfont (on the mt32pi itself). it always sounds off, unlike when I use the ao486 core. Is there something I'm missing? I tried the various options in ScummVM but it still plays weird instruments. Just a guess, Its possible its send...

Will the installer grab the latest 2.6 version of ScummVM or does it need to be modified? As always, Install_ScummVM.ini will grab the latest ScummVM_Installer.sh and run it. Would it be possible to use the FPGA for the OPL3 sound chip and the MIDI synthesizer, so SCUMMVM wouldn't need such addons? You don't need any additions for OPL3. ScummVM al...

IIRC, SLIP was supplanted fairly quickly by PPP. Are there OSes that have SLIP clients but can't talk PPP at all? Pretty much anything that runs SLIP should be physically capable of PPP, if a software client was written. I know of at least OS/2 2.0 which is the only version that runs (on ao486) with both caches enabled. And what else would it take...

If you disable Nagle's algorithm, I presume you're doing it at the OS level, which would disable it for everything, AFAIK. Mister should be disabling it for this type of TCP connection on its own, so you don't have to mess up every other TCP client. I'm not disabling it at the OS level. I'm disabling it at the socket level for just the outbound/in...

You're right, Nagle's might be a problem. It tries not to send small packets, which is exactly what a serial->TCP link should be doing. It needs precisely timed data, so it should be sending numerous, regular small packets, instead of irregular large ones. That probably should be the default in the Mister transport layer. You might want to raise i...

Games that are meant to run on modems will be entirely insensitive to Internet lag, because modems often had about 300ms ping times. 2400 BPS and slower modems have very little latency. The lag came in with faster modems that introduced data-compression (ie v.42 bis) and error-correcting protocols. Battle Chess is a good example of a game that run...

Wikipedia is not the best source for interrupt information.

@kitune-san

Do you (or anyone) know why the following code does not work on the current PCXT core?
Is this a BIOS issue?

Thanks!

I got it to work with Per.Oxyd!!!! - Set the game to COM 1 and 19200 baud in the game options on both MiSTers. - Set the UART in AO486 OSD Menu to Modem, TCP, 19200 baud on both MiSTers. You can also use UDP mode to eliminate the need for dialing (like a true null-modem link). Simply set the "UDP_SERVER=" option in /media/fat/MidiLink.IN...

Thanks for the tip! I was able to get the Amiga online using Miami (so wild to see live websites in all their "glory" on such an old machine), and I have VirtualLink installed and configured (I think), but can't get MacTCP to work. The Vlink.guide mentions that MacTCP in OS 7.5 is buggy, and I don't see any of the expected networking uti...

Hi all, was just wondering if anyone is doing Mac II core... I know there is Basilisk II configuration which basically makes Mister run Basilisk via it's Linux ARM cpu, but having an FPGA implementation of actual core would be nice. Something that would run System 7.5 or even System 8.1 You can run ShapeShifter under the Amiga/Minimig core. Works ...

King's Quest VII working for anyone? Tried it with both MT32-Pi and SoundBlaster and it has music for the Sierra screen then gets to the title screen and hangs. Mouse pointer keeps moving. Tried with extended and EMM386. I just tested it and I'm seeing the same result as you. I'm sure this worked at some point before because I remember playing it ...
