NeoGeo topic

On a 4K tv try setting a higher resolution using custom resolutions for neogeo in your mister.ini file

Here’s the topic
http://www.atari-forum.com/viewtopic.php?f=117&t=35169

It was my specific HDMI port. I was able to get it running on my TV in 1080p but not in my one and only 4K port - which happens to be my lowest latency port. I'm just going to have to live with it in 720p. Thank you for your suggestion!

hey there,

i recently put together a mister with 128 SDRAM and am having so much fun playing a FPGA NeoGeo system. this is truly a great time for retro gaming to have something this close to original hardware, with a proper 1080p scaler, and the lowest input lag available
the NeoGeo has so many great fighting games, and the benefit of the low input lag of a FPGA is very impressive.

99% of the games have run exactly as expected and dont exhibit any errors, which is just stunning that NeoGeo is already at this point of stability and performance.

there is only 1 game that i have noticed odd behavior with, and that is samurai shodown 5 x (special).
the NeoGeo logo and bios load just fine, no graphical errors, but when the actual game boots up, there are 2 horizontal flickering pixelated lines that run across the screen. one on the top 3rd and one on the bottom 3rd of the screen. there are some other graphical character sprite errors here and there, but those flickering horizontal pixelated lines are the most distracting.

my question is, has anyone else noticed these pixelated lines running across the screen in samurai shodown 5 x (special)
has this been discussed before and furrtek is working on this game to iron out the last bit of graphical glitches/sprite errors

(im using darksoft's neogeo set, playing with the latest update.sh, vscale_mode=2, in 1080p over HDMI)

I saw that vpelletier added a romsets.xml that loads the split up roms from the 25th Anniversary Collection and the not ported NeoGeo games from GoG.com (Metal Slug 2 on GoG is ported and does not contain any ROMs).

The romset list is not complete yet (e.g. Blazing Star is missing). How do the loading and index-entries work exactly so we can help complete that list? I tried to make a romset-entry for Blazing Star, but get corrupted sound and graphics, I assume that is, because the c-files are 4MB and not 2MB?

From when I converted the Anniversary Collection ROMs I still know that:

• Encrypted: garou, kof2000, kof2002, samsh5sp, sengoku3

• prom needs splitting and reversing: mslug, twinspri, ironclad, samsho2, turfmast

Some games contain enough files to build two different sets as per neogeo.dat:

• lastblad,lstbladh:
  Concatenate 234-p1.p1 and 234-p2.sp2 to prom for set "lastblad". Concatenate 234-pg1.p1 and 234-p2.sp2 to prom for set "lastbladh".
• rbff2,rbff2h:
  Concatenate 240-p1.p1 and 240-p2.sp2 to prom for set "rbff2". Concatenate 240-pg1.p1 and 240-p2.sp2 to prom for set "rbff2h".
• shocktro,shcktroa:
  Concatenate 238-p1.p1 and 238-p2.sp2 to prom for set "shocktro". Concatenate 238-pg1.p1 and 240-p2.sp2 to prom for set "shcktroa"

Metal Slug 2, which has 8MB C-Files works out of the box:

Code: Select all

	<romset name="mslug2" pcm="1" altname="Metal Slug 2 - Super Vehicle-001-II" publisher="SNK" year="1998">

		<file name="241-v2.v2" index="24"/>

I tried simply modifying the entry for Samurai Shodown II, which has 2MB C-Files:

Code: Select all

	<romset name="samsho2" pcm="1" altname="Samurai Shodown II" publisher="SNK" year="1994">

for Blazing Star, that has 4MB C-Files to:

Code: Select all

	</romset>

The game starts, but sound is only a beep and after the first screen the graphics are garbled.

Anyways, I would like to help, but need a shove in the right direction.

[PikWik]

also, are there any plans to add a CPU overclocking option to the neogeo core?
something that could help/fix the slowdown in games like metal slug, twinkle star sprites, & blazing star?
i know this is just how the games were made and the slowdown is also on original hardware, but something similar to what the genesis and SNES core have for CPU overclocking would be very nice.

There are lots of small graphical issues in many games, some are listed here https://github.com/MiSTer-devel/NeoGeo_MiSTer/issues
Hopefully they're all down to the same 1 or 2 bugs and a fix will help out all the games at once.
Furrtek is busy making his NeoCD SD Loader at the moment https://twitter.com/furrtek

[PikWik]

ahh, apologies, i didnt know thats where people were posting issues with the cores/games

im sure these graphical issues will be ironed out, this core is so new (but very impressive so far)

[Threepwood]

Hm, nobody can explain how to determine the right index values to use with the gog and classic complete collection NeoGeo ROMs?

Hello

I am getting "backup ram error msgs" among other errors while trying to launch any type of neo geo game. I am using the darksoft rom pack with the file structure set up properly. I did run memtest for 10 mins with no errors, and I have tried multiple clean installs with just the NeoGeo core only with no luck. Could it be a defective ram module? I am able to run SNES, Sega CD, NEs with no problems. I have also tried setting different Bios in the core option and each bios gives a random error, Ram errors, or bad contact errors.

[Dubon]

Do you have all the apropriate files specified in the readme in place?

[kazki]

You usually get backup ram error when there’s no bios available for the requested mode

Make sure you rename your mvs bios sp-s2.sp1
And your AES bios into neo-epo.sp1

Or just select unibios in the neogeo core and make sure the unibios is present and renamed correctly

Do I need to add the mvs bios sp-s2.sp1 and AES bios neo-epo.sp1 into the folder if I am running the uni-bios? I am having a hard time finding the neo-epo.sp1, what I did do was take one of the .sp1 in the neogeo.zip bios folder and rename to neo-epo.sp1 with still no luck.

[kazki]

If you use unibios and have a uni-bios.rom in your neogeo folder you don’t need neither the sp-s2.sp1 rom (euro mvs bios) nor the neo-epo.sp1 (export aes bios)

In addition, several bios files must be placed in the NEOGEO folder for the core to function properly:

000-lo.lo
sfix.sfix
sp-s2.sp1 (MVS)
neo-epo.sp1 (AES)
uni-bios.rom

The mvs and aes bioses are optionnal as long as you set your neogeo core with unibios, but sfix.sfix and 000-lo.lo are mandatory files, I had issues at first with 000-lo.lo

I finally figured out what was wrong, I was FTPing the files over to my MiSTer. Once I actually copied the files to my sd card from my PC the games booted fine.

I can't speak for everyone, but in my experience tested with 2 different sd cards, the files cannot be FTPed to the MiSTer.

They can. Make sure you transfer them in binary mode.

[Chris23235]

I am using Filezilla to transfer files via FTP all the time, it works flawless.

Thank you for the tip, I will defiantly try this next time.

I was playing through Sonic Wings 2 using Unibios 3.3 and all sound stopped after a brief fade out mid play (on stage 9 )

Hadn't had such an issue on a full run using original bios earlier, nor after doing another one switching back to original bios. Could just be a rare incident, but when issues are found in games it may be better to give the original bios a try, especially since the unibios is currently set as the default/recommended setting.

I also had the total sound dropout problem with Aero Fighters 2 after entering the New York stage.

I also had the total sound dropout problem with Aero Fighters 2 after entering the New York stage.

I ended up having the same issue in AF 3 even using original bios, so it's not a bios issue but rather a core issue with both AF games.

It doesn't happen every time it seems. The first time I played it a few days ago it was fine, so there must be some specific condition that causes it.

[Peredonov]

Seems kinda random to me. Just have to play the games long enough for it to eventually happen. Usually I only saw it on a late stage or on round 2 after the ending.

So it may not be easy to debug this issue, but hopefully as the core becomes even more accurate it can be resolved naturally.

I noticed the same thing twice in the last week too. I am not sure if it was connected to the New York stage, however. Twice while playing the music totally dropped replaced with a sound. Once the game ended and I naturally returned to the main screen (no resetting or anything) the sound returned to normal.

Just wondering if anyone has updated lately and had constant issues with the NeoGeo core ?

On power up of the core, I get constant Hardware Failure messages from BIOS.. if I force AES to continue the games start but not soon after I get an Illegal Message Error and the game crashes.

Tried rebooting etc.

Memory passes Memtest @ 140Mhz with 0 errors for hours.

[kazki]

when you update, make sure you also update the MiSTer, the menu core

I've read some similar issues from old MiSTer firmware and so on

as long as you get the right roms with the right gamelist.xml file and the right bios you shouldn't have any issues at all.

if so, try to delete the config folder (it has your pref for each core), just keep the input subfolder inside your config folder

Did it run fine before the update?

[andrewwong2000]

Did it run fine before the update?

Yeah it was working great. The only ROM that didn't run at all was Crouching Tiger Hidden Dragon.. everything else ran perfectly.

Will try kazki's recommendation
