@JimmyFromTheBay said in Can the Konami Arcade Advanced ROMs run on an NES emulator?:

running them on an VTxx emulator

Fixing your typo.

I'm not saying there are no VTxx emulators, you know at the very least about one (MAME/MESS). There might be others.
You seem to think that it's normal for an emulator to support every kind of similar hardware, but it's not (e.g. most console emulators are unable to emulate their arcade counterpart).

Edit : i found this old topic : https://forums.libretro.com/t/which-core-would-you-best-recommend-to-play-old-nes-bootleg-games/36763

Whats strange is if I play Castlevania on my desktop in Mesen at 1x scale this same phenomena occurs (its not an aspect ratio or integer scaling issue either, those settings dont alter this in anyway) At 2x you can still see it happen but not as apparent. 3x and up it doesnt happen. But if I record gameplay at 4x then open the video in VLC and set zoom to 1/4 bringing the image back down to 1x, there it is again!

What the heck is going on here? Is this some sort of lcd pixel refresh rate thing? It happens in games like Castlevania, 8 Eyes, and Ninja Gaiden, but not Super Mario Brothers. It also happens in other system games like Rastan for Sega Master System. And changing the emulator/core doesnt affect the outcome.

I would love to know exactly what causes this.

@mitu Thanks a lot!!! I changed the hostname and all cores are installed correctly

I know I’m really late to this party but had to say I too love maddog mccree.

I’m about to build a gun4ir in the next weeks in hopes to have a satisfactory gun for it.

Just my findings:

Add missing variable to save state

This is the commit that breaks the loading of existing state files from old pi's.

And for anyone's future reference: here is the github issue regarding it: https://github.com/libretro/libretro-fceumm/issues/215

@montecore >Sounds like there's nothing that can be done

Well, you could manually recompile it from an earlier version to get back to where it was but as far as converting the savestates I'm not aware of any method

A single dance pad can't be used even to get half of the Power Pad because the center square on dance pads is not active. Assuming the Power Pad works inside like a Konami dance pad, the sensors are analog (pressure sensitive resistance), so you can't just hook up the guts to a PI, and you need a microcontroller with 12 analog pins. I don't know if the Power Pad's digital electronics can work with the PI's 3.3v GPIOs. A full solution for the Power Pad 12 button side is to overlap TWO dance pads and use bleeding edge fceumm libretro core: https://www.instructables.com/Playing-NES-Power-Pad-Games-in-Emulation/

@TPR I change my settings inside the retroarch gui in-game. Should be under Quick Menu\ Options

Yeah I confessed.

Thanks, I've learned about getting in the RGUI with a hotkey, which I didn't know about before.

Thanks again

The reigning theory is that the issue comes from missing HEADERS. The NES requires Headers in the ROM or it won't boot. However, just recently posted information suggests that unzipping the ROM may solve the problem. I've not been able to test this myself since I'm troubleshooting controller issues right now. Please let everybody here know if unzipping works for you!

I tried them both now, and nestopia definitely has the better audio emulation. Mario 1 dying sounds so inaccurate in fceumm. In the past, nestopia had this strange sound bug every now and then but I no longer hear it. Though, maybe the fceumm audio accuracy might be improved in the future?

And can I recommend having the Unsaturated or Nes-Classic Palette as default? They look much better on both emulators.

@laephis I had a issue were my tv would only use pal 50hz even when I ran a usa nes rom .... Hence I had stuttering and slowdown try a pal game see if that runs fine if so that's your issue. I had to change the .config to force my tv to find 60hz maybe this is the same issue.

^^^^^ issue solved I speak through my hoop

@BuZz
Thanks!
So the (re)installing process remains necessary, but now we can do it from binaries, right?
And on RetroPie 3.8+ it won't be necessary, right?
