Congrats on the commit to the master branch! What's next for AO486? :D The DOS Protected Mode Interface (DPMI) bug in the core is a pretty big one that no one has been able to figure out. It affects many many games that only bomb on the core and not in emulators or real machines. For some reason, DOS32a works around it most of the time. https://gi...

What about SSD/USB boot, so you don't need the SD?.

Hi friends, Sorry if this has been answered. Is MiSTer - or could be - capable to boot from USB, so we could get rid of the SD and have a more stable drive for all the system (including roms, cores, OS/linux, etc.). Just as a reference, I think that using the last Pi4 firmware is possible, but no from the previous Pis. So must be some hard limitati...

Hi friends, Sorry if this is not the right place, I'm trying to find the right core (if exists) for the previous generation of the 286 computers. Looking for some information about my neighbor's computer, where we played Digger, Golf, Livingstone on a monochrome monitor. I found this "Mitac PC portable". aqjYbpN.png Is there any core to r...

Soo removing dino rom, cadillacs MRA and going through Update_all worked!.

Thanks guys.

Sorry if this has been answered, I didn't see this on the CPS15 thread. Someone have had the same problem?, it seems to happen just with the background. Sprites, animation, etc. works fine (and any other CPS1.5 rom works ok on my MiSTer). https://imgur.com/a/tTsZWYW MiSTer v210109 dino v210101 jotego Roms downloaded and updated via update_all (retr...

Hi all, Sorry if this has been solved and updated somewhere. I've seen some threads with different memory configurations in old posts like https://misterfpga.org/viewtopic.php?t=955 , but I would like to lknow if there is some official recomendations for max stability/compatibility on DOS 6.22 and DOS 7.1. My current EMM386 line: EMM386.EXE AUTO RA...

Would the ppp connection work when in Windows 98?.

Or you would need to replace the PPP client (Trumpet Winsock 3.0). It looks that this is mandatory for W95. https://github.com/MiSTer-devel/Main_Mi ... rted-cores


What should be the easiest way to get internetin Win98?.

Best,

So one solution might be the 16MB RAM option Just want to add that the memory cap is not a solution. You can try to limit memory to 16mb through OSD and Warcraft II over its default DOS/4GW won't pass. Btw Warcraft II specs: Computer: Warcraft II requires a 100% IBM PC compatible computer, with a 486/33 MHz or better processor and at least 8 megab...

Hi all, AO486 and MiSTer are awesome, and we are amost there to get the perfect replacement for an entire era machines. As most of you already know, there are some memory bug causing a significant difference between MiSTer and a real DOS machine. We are trying to document this in several ways to get some clues [ https://github.com/MiSTer-devel/ao48...

If nobody else has an issue with this, it might be my DE10, or my DOS installation (which is just a barebones DOS 6.22, Spanish version with vide-cdd, cutemouse and unisound). Hi Vorvek, I agree, something is happening with this core regarding compatibility. Perhaps is my impression. But computers from this era (having quite different configuratio...

What about PsychoPinball?. Someone has been able to pass the menu?.

Everything seems to work OK until you load a table.

The DOS compatibility issues are weird, perhaps is related to the memory configuration from our side or something not standard in this core for a common 386/486 machine. Games that would not give any problem in almost any real DOS HW, or even DOSBox, are not working or present glitches (we should make a list, but usually games after the dos4gw or w...

Cebion,

I'm using this little capture card, you need a host computer to record the video:

ao486 Cache 34 Windows 98 SE (no drivers or extra configuracion required) As you already know this is completely out of the a486 core scope - all these games and software are designed for Pentium processors - but is a good example of the stability and the great work done by the team developing the ao486.

Sure, ScummVM and emulators are great for certain games, but here we are looking for the full experience of having a working DOS computer and all its content running on it.

Right bigern77,

I think it's solved: https://github.com/MiSTer-devel/ao486_MiSTer/issues/20

But I'm not sure if you will find the fix on the regular scripts (if you would get the last bios/code through update_all, etc.).

There is something weird with the SoundBlaster or sound implementation on the core.

For example, once you set the right SB parameters, you can enable the music for Supaplex, but at the moment you try to enable the sound effects, it halts the machine.

Hi all, The last contact I had with Super Hang-on was 25 years ago on MD, so I'm not sure about the actual performance of this game. A few things regarding the "feeling" of this game on MISTer. - Was this slow when you press any direction?. I feel like a high latency but could be something related with the animation of the motorbike (just...

Awesome, tRAcE. Thanks Goingdown.

The EMM386 setting works perfectly.

It looks like quite common hardware, but Toaplan had their unique arcade system so I don't know if this rom could work (with some minor modifications) on any of the current -or under development - cores. CPU 68000 (@ 8 MHz ) Sound: Z80 (@ 6 MHz), YM3812 (@ 3 MHz) https://en.wikipedia.org/wiki/Snow_Bros. It was a popular arcade in Spain, would be re...

I agree Cebion, Sorgelig mentioned the ao486 implmentation is mostly based on scripts, so the performance is quite limited without a refactoring. From the Jotego patreon, this kind of complex processor would need some "hardcore" work and probably a team: Jotego -"En algún momento quisiera mirar las CPU de Intel, pero seguramente es u...

Thanks KnC,

Sure, I will share a comprehensive list of working games on the ao486 MiSTer here. Perhaps we could move it to the ao486 wiki to help following future core improvements.

Best,

Hi all, This week I got my MiSTer and I plan to test my 180 DOS game collection to help with the development of any DOS related project. I will focus on potential problems and offer some information about the current state and actual performance of this awesome core. This is a first impression video that includes an initial benchmark of the CPU and...

I see that the Jotego scripts download and config some of hist Arcade cores, but for example "Double Dragon" is not included on them.

It's because they are not final and we should wait?. Is there any updated script for new cores?. What would be the standard way to install them, manually copy each file?.


Best,

After the first reboot on DOS 6.22 (128 SDRAM), memmaker find some error so it cannot continue (and discard changes).

Is something we can solve vía software/configuration or it's because of the hw/memory implementation of the DE10?.


Best,

I'm not sure if the nano FPGA board is equipped with a temperature sensor (like the TMP441AIDCNT, which provides temperature sensing on http://www.terasic.com.tw/wiki/DE10-Advance_Hardware_Manual_revC_Chapter4_Temperature_Sensor,Fan_Control_and_Power_Monitor) If this is the case, is there any easy way to read this sensor?.
