Problem fixed!

Changed power supply and all the weird glitches and problems with the core have disappeared.

Worth noting if suddenly things go weird

You were not using the default power supply that ships with the DE10 Nano? 3rd party power supplies should be avoided, unless they've been tested and approved by the community here or some of the good MiSTer board sellers.

No. Just get a good brand PSU with the correct voltage and enough amps, like the Meanwell GST60A05-P1J https://www.meanwell-web.com/en-gb/ac-d ... 60a05--p1j and you are set.

I was wondering, would it be possible for the core to reproduce a multi-slot MVS? Obviously the even higher memory footprint of loading multiple games would make it unpractical, but it would be an interesting novelty nonetheless?

Congrats to anyone involved in this core btw, real impressive work! I can definitely see this replacing my real hardware eventually.

I'd love this I've done that in MAME before, kind of pointless but still interesting and makes for a more varied attract mode. We could fit a few of the smaller games into the 128MB. There are more important things that should come first though.

Just got the neogeo core set up on my mister with universe bios 3.3 and its all working great except it keeps resetting the region and aes and mvs selection every time i reboot or change to a new game. is there any way to save it so the mister boots up the neogeo core with the selected settings on the universe bios I've set every time?

Cheers for any replies

You can save the region and MVS/AES by saving to the memory card. It's probably best practice to leave auto-save enabled. You will need to do this with each game, but once it's set you're good to go

You can set auto-save like djsquare suggested, though you will still need to change the region and other settings when booting any game for the first time. I found it easier instead to just grab an official bios for the region I use most and renamed it as the European official bios (since that's what this core looks for). You can easily access dip switch settings from official bios anyway, so the benefits of unibios are not exclusive.

[MrMiSTer]

Thanks for the info guys will try it later

core works really good for me.
next step would be Neo Geo CD.... but i don't know if we will ever see it on Mister..

most likely, no.
And generally there is no point to have it as it has only ONE exclusive CD game. CD versions of games are crippled comparing to cart versions.

[kazki]

Hi Sorgelig, as a Neogeo enthousiast, I beg to differ, while it is true there is only 1 exclusive game (Samurai Rpg) and some larger games were somehow crippled due to the video Ram limitation of the neocd

Cd games also have additional content such as arranged music tracks, more ways to play a game (the combat school in the 2 Metal Slug), Windjammers has a unique gameplay you have to score 24 points in 95 sec which is a game changer, you can unlock galleries, openings and so on
Real bout Special also has a special Mary Blue ending

To get it simple let’s say that everygame that is less than 200Megabits is on par with the carts, larger games tend to have limited animations (kof limited animation in background), smaller sprites (art of fighting 3) or abusive loadings (last blade series)

Not relevant to the fpga, furrtek has released his ODE for the NeogeoCD, loading times are excellent compared to the original hardware. They are a tad slower than the NeoSD pro when loading a CD game

[Sorgelig]

Ask furrtek to finish the CD version

[Mlaurito]

I love you Sorgelig, getting to the point with no words wasted in between

[kazki]

@Mlaurito you should search who made the Neogeo core possible first

I'm not asking anyone to make a Neogeo cd core, I'm just giving my personal insight to the fact that Neogeo CD could be a challenging project and that there's more that meets the eye when you try the games and compare to the cart versions

I gave the pros and cons, yeah Sorgelig might be right taking the shortcut and saying NeoGeoCD games are "crippled" versions of the original, I just offered an alternative from my perspective as a NeoGeo enthousiast

as I said the fact that furrtek released an ODE is NOT relevant to the fpga scene

I love you Sorgelig, getting to the point with no words wasted in between

Sorgelig, just for my personal knowledge..
When furrtek released the neo geo core there was a cd implementation that was not enabled... but i should like to know what it was missing to finish, i mean if it was at a good point or only at the beginning.
Do you have this info?

It's better to ask furrtek. According to what i remember CD code wasn't finished and had a problems with DMA. That's why CD option wasn't available from the first versions.

Yesterday i tried for the first time the Neo Geo core (20200123): MVS mode with Unibios 3.3, 32MB SDRAM and HDMI out. First I tried Metal Slug, and everything seems fine at the beginning, but going ahead in the first level the sound effects disappear; the music goes on but I can’t hear the gun shooting or any other sound. Then I tried Puzzle Bobble and got no sound, but music, since the beginning. I tried to power off and on MiSTer a few times with the same results.
Any idea?

Thank you in advance.
Regards.

Try older releases to see if it's new problem and if there are version without this problem.

I tried back and forth NeoGeo_20200123.rbf and NeoGeo_20191205.rbf: NeoGeo_20191205.rbf seems to be ok.
I tested a dozen of runs of the first level of Metal Slug. Sometimes NeoGeo_20200123.rbf is ok, but most of the times it cuts audio effects. NeoGeo_20191205.rbf was always ok.

Thank you in advance.

I've never noticed anything amiss. I tried to check if I could reproduce the sound issues you described, using MVS mode, Unibios 3.3, core is NeoGeo_20200123, but I just played Metal Slug up to the 3rd mission and everything's fine. Music and sound effects are all there.

Only difference to your setup is that I'm on 128MB SDRAM and using direct video via HDMI.

Probably it's general core instability. Core uses many async clocks which is unstable. Basically code needs big refactoring to be more compatible with FPGA nature.

[kazki]

Have you tried another psu ? andrewwong2000 reported above having issues and then having them resolved with a PSU change

[daty2k1]

I keep having sync issue with my monitor when switching the system to NTSC. I think it could be related to the fact that the core is running at MVS speed. Could someone point me in the direction to compile my own core with a different clock to get the AES rate (59.6hz)? Thanks

[daty2k1]

OK I finally figured it out. I'm not sure I did it right but it works! The fork is available on github if anyone is interested.
