Neo-Geo Graphic Issues
« on: March 01, 2010, 04:02:07 pm »
Hey Everybody,

First time posting in this forum. Just purchased my Dingoo not too long ago. Hope someone can help me out here. Is anybody else experiencing graphical glitches in their Neo-Geo games? I downloaded a pre-converted Romset and got everything loaded into my Dingoo with no issues, but once I fired up the games I've been getting some weird results. Keep in mind that these games are supposed to be compatible with the emulator.

For example:

    * 2020 Super Baseball & Baseball Stars 2 has issues where some fielders are just a jumbled mess of pixels, plus you can't see the baseball when it's pitched.
    * In Crossed Swords, enemies in the background are a jumbled mess until they are right in front of the your character. The enemy suddenly just comes into focus.
    * You can't see any of the pins in League Bowling. Again, some jumbled pins come into view once the ball is in play and it gets close to hitting them.

Similar issues are happening in other games as well. The neogeo.zip folder is in the same directory as the MVS folder, which I read might have been a problem. If this issue sounds familiar to any of you, I would appreciate any help you can provide.

Thanks!

It sounds like you more than likely have corrupted or otherwise buggered rom files. I noticed the same sort of thing you describe in many of the same titles, also in Samurai Shodown and Neo Turf Masters.

Try downloading some games again and see if there is any change. I can confirm that Baseball Stars, Baseball Stars II, League Bowling and Crossed Swords all work fine on my system after downloading new copies.

Thank you jeremymtc for your reply. I downloaded an "arcade perfect" set and converted the files with the MVS converter. Unfortunately, I'm getting the same results as I did last time. I don't know if it's the actual ROM's or if there is something fishy going on with the emulator itself.

I understand it's not supposed to be brought up, but I'm curious as to where you got your ROMS compared to mine. Perhaps you can send me a quick PM?

Anyways, thanks again for your help.

Hi Mike. Your problem is almost certainly the rom files themselves.

Over the years several different emulators have been authored for the Neo Geo MVS arcade system, with quality ranging from MAME's technically very accurate emulation to some fairly loose high-level-emulators like NeoRageX. High-Level-Emulators mimic the output of the original game and usually run the games fairly fast, but typically don't actually emulate the actual hardware of the original game very well or very closely. Many of the HLE emu authors used to hack or otherwise make changes to the MVS rom files in order for their emulators to be able to run the games.

The net result is that many years on (in the present), you have sets floating around which are "acrade accurate" as used in MAME, and you also have sets which have been hacked or modified to run with specific emulators. To be perfectly honest, I don't know what the Dingoo MVS emulation is based on in terms of the original emulator software, but it's fairly likely that Dingoo Digital used one of the earlier HLE MVS emulators. The upshot is that you need to run a romset which is type-compatible with the included emu, which you may not actually have with an "arcade-accurate" set.

It would be easy to tell what we're actually dealing with by running the working set through something like Roman Scherzer's clrMAMEpro rom-auditing software, but to be honest I can't be bothered to do it right now  ;)

I sent you a PM mate.

if you want to play neogeo games with dingoo's native MVS emulator, you must get the NEORAGE compatible roms, and not the MAME compatible ones. Using MAME roms will result in messed graphics.

Thanks to everyone so far who has tried to help me with this situation, but unfortunately I am still experiencing the same graphical issues with the ROMs. I've tried pre-converted sets, arcade-perfect sets, and NEORAGEx compatible sets. It seems like nothing wants to work. As far as I can tell I've been using the correct conversion software (MVSv1.3mod).

Could it have anything to do with my neogeo.zip BIOS file? Maybe there is something in there that shouldn't be...I don't know. I've run out of ideas. There are plenty of emulators left that seem to work fine on my Dingoo, but I would really like to figure out the reason why this is happening. I'll keep trying with different ROMs to see if something might work.

Thanks again for the support.

i had the same problems with some of my emulators mvs and cps1 and 2 for me tho it didn't have anything to do with the rom set i was using preconverted ones i found on dealextreme forums. I had glitchy graphics and it worked when i downgraded my emulators .sim file. and yes i have encountered the no pins in league bowling and no ball in super baseball. just change you emulator file and it should work itself out no idea why it does it tho.

wiredredneck have you tried the games that use zooming with your downgraded .sim file. games like samurai showdown, art of fighting, lastblade and other examples already mentioned. i got the roms from the same place you did so if they work fine can you post where you got the .sim from? thanks a lot this is good news for me!

wiredredneck i've tried the mvs.sim file from a couple of places including the one you mentioned and they don't fix anything so if you could upload your file that would be great!

Thanks for sharing those files Wiredredneck, but just like shinobi my dingoo is still experiencing the same problem.

I checked out the YouTube video that was posted, and I can confirm that this is the same exact issue I have.

My Dingoo is also an HK model.

it doesn't work for me either. at least we found the root of the problem, the dingoo hardware itself and not the roms or .sim. and recently dingo digital usa was able to work out a fix for the hk dingoo's i'll forward this thread to them and hopefully they can figure something out.

Hi,
I just received my dingoo 2 days ago and i'm facing the same problem with neo-geo games.
Everytime it uses zoom graphics, everything is all giant pixel !
it seems that a number of players are having the same issue with neo geo emulator.
My dingoo is not a hk model, i've tried 3 different perfect romset for neo geo and changing the mvs.sim, deleting all ini files and nothing changes.

apparently in french forums, people are having the same problem, all i think of is maybe changing firmware from 1.2 to 1.22 but i had a reply this morning saying it changes nothing.

I'm not really sure if i installed the right way the famous HK fix, but it changes nothing.

hope we get an answer soon.

I'm having these issues too. The horrible zoom pixelation problem, anyway. I haven't tried anything to fix it yet. I have an HK Dingoo with patched GAME folder, firmware 1.2, with roms that were converted specifically for the Dingoo (that torrent, you know the one).

Sooooo... anyone figured out why this happening yet? I suppose I could use fba on dingux or whatever, but isn't the native suppose to be better at the moment? Why is this happening?  :'(
