That's not the case even less on the MiSTer were a Linux is running in parallel to the FPGA core handling all the USB input/video and audio output stuff. That is precisely why I said the OS is less in the way in Mister, which surely is, compared to a normal software emulation where the OS is more in the way. On a modern OS the emulator can put tas...

Audio stutter in emulation is in almost all cases a problem with to weak hardware running the emulator. If you want to tell me you don't think that a software emulator can reach the accuracy of an FPGA implementation we can stop the discussion here, because this is simply false. "Weak hardware" is a poor excuse for not understanding how ...

I would like to have some improvements to AO486 core, if this is even possible. I understand it's a very complex issue, but it would be nice to get improvements, since it's clearly the largest software library of all.

But this even more proofs the point. In general these games are running in one version or the other on Ares (and at least Tetris (JP) is working fine on Mupen64Plus no idead about Hybid Heaven (JP) ). It's more proof to my point: if Ares really was "accurate" than Mister, there shouldn't be those differences on games not working "ju...

Strange, I didn't tweak any settings. I am using Winn11 but this shouldn't make the difference: I said Tetris JP doesn't work on Ares, you are showing me "The New Tetris (USA)", which is a completely different game made by a different developer (Blue Planet), the JP version is made by Seta and it's really a different (way worse...) game....

Tetris worked fine for me, played for 10 minutes of so. Hybrid Heaven worked for me played for a couple of minutes. Gauntlet Legends finished the first level. As I''ve said, they all crashed in the way I said they did. I was running Ares with all default settings, maybe it might be possible to make them run with some tweaks, who knows. Have you tr...

From the games on your list only Daikatana (JP) and Rugrats in Paris don't work in the latest nightly build of Ares, the other bugs are already fixed. Tested Ares nightly build right now: Tetris N64 still crashes on start, works on Mister Hybrid Heaven JP still crashes on start, works on Mister Gauntlet Legends still crashes when entering a level,...

Is it me, or Cruisin' USA runs too smooth on the N64 core? I played the game on a real console a few years ago and I remember framerate being a bit lower. Tried it right now, side by side Mister and real N64, they are identical. There are other games in which timings are off on Mister, like Knife Edge and WCW Nitro, and they show exactly the same ...

virtuali

The compability list on the Ares website is outdated. I tried some of the games you listed on the latest nightly build. I didn't try WCW and Knife Edge as I don't know if I can tell the correct speed, I never played these 2 games. From the games on your list only Daikatana (JP) and Rugrats in Paris don't work in the latest nightly build of Ares, t...

Note that Donkey Kong grabs 3 vines swinging through the stage. It also looks like this on the Ares emulator. Now compare this to how the attract mode looks on the MiSTer core. On the other hand, using the lates Ares 1.37: Tetris N64, crashes at start on Ares, works on Mister N64 core Hybrid Heaven (JP), crashes at start on Ares, works on Mister N...

As far as I know, the issues with some games are because of Mister's hardware limitations, so I doubt a patch can fix them. One of the key titles and best games on the system, Conker’s Bad Fur Day, isn’t working properly. That alone is a deal-breaker for me when comparing FPGA to software emulation. I don’t see the point in using FPGA if it’s not ...

Any idea about a special .vhd to store saves? We already discussed earlier. It can be done, sure, but it would require custom scripting for each game, since most of them won't allow you to officially select a different drive for saves, so you would need to backup/restore all files involved in saving in the game .BAT launcher. Doable, it's just a l...

A clarification from somebody who used to work for Roland in the early 90's: MT32-pi as a software basically emulates two very different kind of hardware: The original MT32, which is a MIDI synthesizer based on LA synthesis (very short PCM samples combined with digital emulation of analog filters with 4 "oscillators" per voice which Rolan...

Getting a new Raspberry has become more of a tradition for me: I got all models since it first came out, from 1 to 5 not counting the one I use as an mt32-pi. So, when my new RPi5 8GB arrived (lots of power, according to all reviews), I downloaded a 500GB Retropie image full of stuff with a super cool interface with covers, animations, everything. ...

When I launch Super Mario 64, it is using the save games from the MiSTer, not from the memory card Even on a real N64, Super Mario 64 doesn't use memory cards from the controller pack, it saves directly on the cartridge. N64 saves were fairly complex with different methods to save on cartridge and then the controller pack, see here for a list of g...

The main problem is Dos is quite limited and there were no standards: almost every game saved its data in its own way. Sure, something can be done, it's a lot of work, because each game must dealt with some custom treatment but, for example, it might be possible to do something like this, see two possible approaches: 1) A separate .VHD used for sav...

virtuali

This should work on Mister instead:

virtuali

In addition to that, since the N64 Core is released under the GPL license, even assuming Analog will use it (which doesn't seem the case, and that's another good reason why it's best to get facts first before assuming anything), they would be completely in the clear using it, as long they'll comply with the GPL license, which means open sourcing an...

virtuali

The project is using a straight foward basic DOS setup that is applied to all games, with some smaller changes for some particular titles. Sorry, but isn't this kind of contradicting the main point of this collection that each game can have a completely different Dos configuration without affecting the other games? That's the main attraction of pa...

virtuali

Nice so, you are creating .VHDs programmatically, right?

Have you considered some kind of variable parameter to tell, game by game, how much extra free space each game might need when running? I found a couple of cases where the .VHD was made so tight, so the game started, but didn't have enough space for the Saved games.

DR-DOS is better at freeing conventional memory than MS ever was. That may help.

I tried the method of starting MISTERFS, copying the relevant files from the Shared folder then MISTERFS /u to unload it, and it seems to work fine.

virtuali

Maybe using the support for the /shared drive in the core would be the better/easier way? That’s what we do for AmigaVision, it could just be a single file in that directory on the MiSTer SD card that lets the system know whether to configure for MT-32 or not. I'll try that, the main issue is the MISTERFS.EXE takes a bit of conventional memory, wh...

And it works! Here's an example with Ultima 6: ultima 6.zip I made two 160K floppy images, the one named MT32MARKER.VFD contains only one empty file named "mt32" at 0 bytes in length. The two Ultima VI MGL files mount either the MT32MARKER.VFD or the SB16MARKER.VFD (we must mount something otherwise the .bat file will error out), as flopp...

I would have to identify what the sound config file is for every game that supports MT-32. Either make a separate VHD, or have some batch file logic that looks to see if an MT-32 "marker" disk or file exists in DRIVE A and copy the correct sound config file at run time to select MT-32 sound. That's an interesting idea: using the "fi...

virtuali

But it's not configured to use the MT32. Any idea how to set this up? We discussed this earlier here: https://misterfpga.org/viewtopic.php?p=84516#p84516 I think all games in this collection assume Soundblaster for music, and they usually don't have a config utility from the original game so, as it is now, it would require a separate .VHD JUST to ...

0MHz DOS collection is for people like myself, who only played a few DOS games back in the day Agreed. For me it's the same, in reverse, with AmigaVision. While I used to have an A500 back in the day, I used it like a game console, didn't knew much about the OS, so thanks to AmigaVision, I can now play those games easily, because I wouldn't want t...

If you want to integrate this fork with the downloader script, just update the following entry with the db.json.zip from my repository:

[distribution_mister]db_url = https://raw.githubusercontent.com/spark ... b.json.zip

Which file, exactly? One of the .PY files in the Scripts\.config\downloader_latest.zip ?

virtuali

I don't know exactly how this might work, if we really need to inject a whole file, or if could at least send some kind of signal from the outside, which the Ms-Dos that runs in the core might use.

Is there anything in the AO486.CFG that might affect something in the core that might be read from Ms-Dos?

virtuali

The following PR I have just created may be of interest Yes, it's a useful solution, which seems easier to use than the core configuration bits. This might replace having to use SYSCTL.EXE from the Ms-Dos, to do things like setting the clock speed, and will make it easier to tweak compared to having to mount the .VHD and edit the autoexec.bat. The...

I just got an email saying the Ultimate Spinner PRO was back in stock. Clicked the link and already out of stock?

Same here, I wonder how many they had, and how many emails were subscribed to.
