Re: ao486 wish-list
Didn't had problems, video was slow, but my guess is that the CPU was to slow. Didn't had a problem getting the game run, but once I was ingame everything was so slow.

Re: ao486 wish-list
Yeah having support for 4 VHD's would probably make things easier to play with. And since IDE systems of that era generally had support for 4 drives (usually but not necessarily one or two optical drives and two hard disk drives) it would be most accurate to the aesthetic.

Re: ao486 wish-list
Even if it would only be able to use ISO images that would be pretty awesome to be able to hotswap ISO files and not have to use CD emulation.
I was looking at the AO486 code, since its all open source and wanted to see if I could make some sense of it, and right now the two drives uses one controller each and acts as the primary drive on each IDE controller. So if someone could figure out how to add support for a slave HDD for one of the controllers, it would probably be possible to also use it for the second controller.Reed_Solomon wrote: ↑Tue Aug 18, 2020 3:34 pmYeah having support for 4 VHD's would probably make things easier to play with.

If CD drive support is to be added, it would probably end up also using one of these controllers.
I guess it might also be possible that a SCSI controller could be added. Not sure if they had DOS support? But that might add support for even more drives. I am guessing it would be more complicated to add SCSI support since there already is some... I assume IDE support.
I have been told that there is some problems with the IDE controllers as it is now, which is the reason why reading and writing to HDDs on AO486 is so incredibly slow.

I would mostly just want the VGA scroll bug fixed where the screen is not drawn all the way and is missing a few pixels depending on the per pixel panning.

Re: ao486 wish-list
It used to be working just fine until Sorgelig forced the core through VGA scaler.
Re: ao486 wish-list
Well, I'm not very familiar with core programing, but I'm sure he has a good reason to force it off, maybe it was dangerous for the hardware or something? I don't know. Still, I hope we could get it back one day.HMPoweredMan wrote: ↑Wed Apr 07, 2021 10:15 pmIt used to be working just fine until Sorgelig forced the core through VGA scaler.

Re: ao486 wish-list
would 3dfx be a valid wish? I mean I know thats a little later than 486 I had it with my pentium 166 but this is pretty speedy core

I can't remember but it was maybe down to certain DOS games running at 70Hz, which is largely unsupported with more modern monitors...?Malan wrote: ↑Thu Apr 08, 2021 4:03 pmWell, I'm not very familiar with core programing, but I'm sure he has a good reason to force it off, maybe it was dangerous for the hardware or something?

I could easily be wrong here.

I'd love to see 3dfx, but not sure it'd be feasible. I'd prefer an FPU first...lordoftime79 wrote: ↑Thu Apr 08, 2021 4:09 pm would 3dfx be a valid wish? I mean I know thats a little later than 486 I had it with my pentium 166 but this is pretty speedy core
Re: ao486 wish-list
if you really want ISA slots this might be an option, http://arstech.com/install/ecom-prodshow/usb2isar.htmldeath5126 wrote: ↑Mon May 25, 2020 11:40 pm good afternoon, all
after running the ao486 MISTer core for some time. i have a few items wish-list items that seem to be missing.
-- a clone of the intel 486dx
-- on bored cash 128kb
-- ram size options 4mb / 8mb / 16mb -- its 64mb at current witch is over kill and lowers compatible titles
-- ibm os2 support
-- support for direct draw
-- an 16 bit ISA add-on would a nice inclusion for sound and video cards
the amount of work on this core to this point is amazing, and has been an amazing experience with on point compatibility, my thanks to every on who has worked on this core so far and all of the ongoing projects on the MISTer.
Re: ao486 wish-list
another thought I just had was having a ISA adapter card made so the DE-10 nano could be plugged into a passive backplane board. the spec sheet claims there are 145 user configurable GPIO pins available. perhaps this could be configured to work with the SDRAM by way of a CPLD chip.

Re: ao486 wish-list
For the Minimig core, it seems its possible to emulate the 68K CPU on an ARM CPU, making it work a bit like PiStorm for the Amiga.
PiStorm is a Raspberry Pi expansion for an Amiga that plugs into the CPU slot in the Amiga and then the Pi emulates the Amiga CPU. Usually the problem with emulation is that when emulating on a CPU, you cannot run every single chips instructions in parallel, which adds some possible flaws in the emulation because the timings will be off a bit. But when you only have to emulate the CPU that is much less of an issue since you wont have to deal with audio and graphics chip emulation all at once and it is much more likely to be cycle exact and have no added latency and other possible problems.
This same logic is being experimented with for the Minimig core and while its not fully working, it is working though. It boots and can run benchmarks and such... and even add MMU and FPU.
So I was thinking the same thing might be possible to do with the AO486 core and be a way for us to see a nice leap in performance, and get FPU as well. Possibly even more advanced features as well. On the Minimig core they are using QEMU, which already has x86 emulation as well.

Re: ao486 wish-list
Yeah this is the most exciting part of going hybrid. It will do wonders for the A0486. We can even imagine having a GPU running on the FPGA while the arm is running the CPU. It could probably go on to emulate a pentium 1 or 2 on the arm while you run advance features on the FPGA. And while I'm sure some people will scream "Blasphemy" most will be very happy,Caldor wrote: ↑Fri May 07, 2021 11:15 am For the Minimig core, it seems its possible to emulate the 68K CPU on an ARM CPU, making it work a bit like PiStorm for the Amiga.

Re: ao486 wish-list
Tempest 2000 please, and X-Quest if it's in the exodos. I tried to look at the catalogue pdf but the site was timing out - can't think why?
