OpenEmu Core plugin with Mednafen

OpenEmu

OpenEmu is an open-source project whose purpose is to bring macOS game emulation into the realm of first-class citizenship. The project leverages modern macOS technologies, such as Cocoa, Metal, Core Animation, and other third-party libraries. One third-party library example is Sparkle, which is used for auto-updating. OpenEmu uses a modular architecture, allowing for game-engine plugins, allowing OpenEmu to support a host of different emulation engines and back ends while retaining the familiar macOS native front end.

Currently, OpenEmu can load the following game engines as plugins:

• Atari 2600 (Stella)
• Atari 5200 (Atari800)
• Atari 7800 (ProSystem)
• Atari Lynx (Mednafen)
• ColecoVision (CrabEmu)
• Famicom Disk System (Nestopia)
• Game Boy / Game Boy Color (Gambatte)
• Game Boy Advance (mGBA)
• GameCube (Dolphin)
• Game Gear (Genesis Plus)
• Intellivision (Bliss)
• NeoGeo Pocket (Mednafen)
• Nintendo (NES) / Famicom (FCEUX, Nestopia)
• Nintendo 64 (Mupen64Plus)
• Nintendo DS (DeSmuME)
• Odyssey² / Videopac+ (O2EM)
• PC-FX (Mednafen)
• SG-1000 (Genesis Plus)
• Sega 32X (picodrive)
• Sega CD / Mega CD (Genesis Plus)
• Sega Genesis / Mega Drive (Genesis Plus)
• Sega Master System (Genesis Plus)
• Sega Saturn (Mednafen)
• Sony PSP (PPSSPP)
• Sony PlayStation (Mednafen)
• Super Nintendo (SNES) (BSNES, Snes9x)
• TurboGrafx-16 / PC Engine (Mednafen)
• TurboGrafx-CD / PCE-CD (Mednafen)
• Vectrex (VecXGL)
• Virtual Boy (Mednafen)
• WonderSwan (Mednafen)

Minimum Requirements

macOS Mojave 10.14.4

Building the default branch requires Xcode 14.3 and macOS Ventura.

mednafen-core's Issues

Is there any way to add filters?

I need that upscaling filter that upscales the resolution a couple of times,does it look much better?
No,but my PC can easily handle 2D Emulation,so I want the "best looking" graphics,other filters like xbrz would be cool too,I don't use it,but I want to have it.

Completely broken after recent OpenEmuKit changes.

I had to rollback a recent OpenEmuKit change for the Mednafen core to launch.

Just a FYI, thanks.

[PSX] Support for non-retail BIOS

It seems mednafen is already able to handle this (related discussion https://forum.fobby.net/index.php?t=tree&th=1939)

UX Proposal 1:

• Let users load the additional files (i.e. PSX-XBOO.ROM and PSXONPSP660.BIN), the same way it does with retail BIOS, and have it check against specific MD5s.
• Let users decide (via e.g. radio buttons) to use retail (will pick based on region) or any of the other ones (picked specificially i.e. I want to load with the PSP dumped BIOS).

UX Proposal 2:

• Let users load one additional custom BIOS file, no checksum validation.
• Let users specify if they want to use the custom BIOS over the retail ones (or simply, if there's a custom BIOS specified, just go for it).

IMO the second proposal would be the least convoluted, and can be easily delivered as an advanced-only feature (Secrets?).

Computer crashes during in-game save/loading world map

-New to OpenEmu. Playing Lunar Silver Star Story (first/only game so far) on PSX.
-Twice now my Mac has frozen while playing necessitating a hard reboot; occurred once when leaving a town/entering the world map, and another while saving the game (in game, not save state).
-Seems unpredictable/difficult to reproduce because this does not occur every time entering the world map/saving. My Mac is generally a happy computer and freezing behavior is unusual, so I don't think it's my machine.
-This occurs while AirPlaying to my Apple TV. However this is the only way I've been playing, so cannot rule out if AirPlay is related or not.

Steps to reproduce

1. Exit a town to enter world map, or use the in-game save function to save game.

Expected Behavior

1. Exit a town to enter world map, or use the in-game save function to save game.
2. Load the world map or save the game without issue, every time.

Observed Behavior

1. Exit a town to enter world map, or use the in-game save function to save game.
2. It either works normally or freezes on the screen, eventually crashing the computer.

Debugging Information

• OpenEmu Version: 2.0.8
• macOS Version: 10.14.3
• file name is: Lunar - Silver Star Story Complete (USA) (Disc 1).cue
• I followed the instructions for setting up a multi-disc .m3u file.
• I also verified the hash for the PSX BIOS files are correct.
• I attempted to locate console/crash reports using these instructions (https://github.com/OpenEmu/OpenEmu/wiki/Troubleshooting:-Console-and-crash-reports), but was unable to find what the instructions were describing - are the instructions up to date? I see the picture links are broken.

Interlacing

Apologies if I shouldn't comment here, but it seems suitable.

There are a few games (Tobal No. 1 & No. 2 sprint to ming immediately) that use an interlaced mode.

Mednafen has video.deinterlacer that could be used to remedy this, though there are a few options (http://mednafen.fobby.net/documentation/#Core+Features%01Using+Mednafen%01Global+Settings+Reference) so perhaps not a single choice that'll fit all.

CloneCD CD image support

Mednafen 0.9.31 has CloneCD CD image support, but I can't open ccd/sub/img files in OpenEmu

Multiple memory cards issue

Hello, I would like to know how to have a second memory card available

I'm trying to play Yu-Gi-Oh Forbidden Memories (PS1, mednafen core) and the game has a multiplayer option, but whenever I try to play, it only recognizes a Memory card in the slot 1, but for de slot 2 it has no data, I have tried to make a copy of the respective .mcr file and also saving with the Save option in the game, but as it only recognizes one Memory card, it will not allow me to save different games, only overwrite the one that I already have.
Is there any way to have multiple saved games (using the Save option in the game or saving in any other way so the game allows me to play multiplayer mode)
Thanks in advance.

• OpenEmu Version: v2.0.7

how to run a hack Saturn game which requires 4M cartridge(original version doesn't require)?

I found the code in the db.cpp, listing the games require different cartridges, but I don't know how to change it, because the file is not there in the package, seems it is sealed in the exec file already, I don't have any skill to change it......

Multitap not working for multi cd psx games

I see the game I'm trying to play here in the multitap supported games (8a5229f)

The game is: @"SLUS-00697" : @4, // Circuit Breakers (USA)

And it works fine alone. But when I create a .m3u file that contains its expansion pack (aka Bonus CD), the game itself and the expansion pack only see 2 controllers.

Is there a way to make multitap work with games that have more than 1 cd?

Analog Stuck Left

Analog always moving left will not respond to right movement. Holding a direct right only negates the left moment keeping me at a standstill. Can still move with and up and right or down and right.

Update Core to address Tombraider

Tomb Raider has some known issues I am encountering in Mednafen. Version 1.27.1 will address these issues.

From Meednafen site:
PS1: Fixed hangs at different points in some versions of "Tomb Raider", a problem initially fixed in 0.9.38.3, but regressed in 1.22.0-UNSTABLE.

EUR games PS1, can't change default localisation from any menu

Hi,

Is it possible to change the emulator language manually on PS1 ?

For example, I have the european version of Metal Gear Solid 1. But when i launch the game, only english language is available.

Is it possible to change core files (like DesmuMe) to do it ?

Regards,
Sillv

SNES support

Hi!
Just wondering what it'd take to get SNES support added to the mednafen core, since the emulator itself can run SNES games?

Thanks,
Chris

Sticky analog stick.

Hiya,

I have noticed in PS1 racing games (Example: NFS IV: High Stakes or Gran Turismo 2) that when driving with an analog stick, there is a tendency for the car to periodically veer hard left or right sometimes. You can compensate for this by moving the stick, eg. if the car veers left, you can compensate for it by steering right, but if you release the stick it will veer back left. This problem is not easily reproducible, it seems to be random and goes away after a bit. You can sometimes correct it by quickly moving the stick in the direction of veering followed by the opposite direction, but not always.

I am using an Xbox 360 wireless controller with the Tattie Bogle driver on OS X Yosemite. I have tried various settings on the dead zone in the driver control panel but it does not seem to impact the problem even if you set a huge dead zone or none at all. If I switch to d pad the problem disappears. So I don't think it is to do with the driver, but I am not completely sure.

I found a fix which might be related from Feb 9 (8f29dfb) but I'm not terribly familiar with Github, so I'm not sure if this fix has already made it into the version of Mednafen I am using or not. The problem occurs both on the current version downloaded by the in-app installer (v0.9.34) and on v0.9.36.4 if I manually try that one.

Is there a way to overscan?

Some Games have black borders or something and I don't like that.

Couldn't communicate with helper application

I compiled this core with success, but this message pops up : Couldn't communicate with helper application...

All the other cores I compiled or downloaded from here/inside the app are working fine, except from the 3 latest mednafen core updates, which give the same message...

Here are the commits that give this message :
04831b3 - Update Mednafen to 0.9.41
c34ac33 - Update Mednafen to 0.9.42
3247fcf - Add analog axis scale support

Same thing with the official experimental release and the compiled source code...

Feature Request:HD Mode 7 and Widescreen support for Snes Like Bsnes

I love HD Mode 7 and WIdescreen,but I don't like Bsnes because it doesn't have Netplay, (to my knowledge) and isn't Eyecandy,so it would be awesome to be able to use HD Mode 7 and Widescreen in Mednafen.

Virtual Boy Side-by-Side 3D Mode

From OpenEmu/OpenEmu#991

I see the Mednafen Virtual Boy core supports side-by-side 3D mode. This would allow playing Virtual Boy games in actual 3D on a 3D TV, as most 3D TVs can convert a side-by-side picture to a 3D signal.

Is this something you all would consider adding to the settings? Or is it there somewhere and I am not looking in the right place?

Thanks! -Ben

Is there a way to change the size of the window and maximize it on fly with the mouse?

That would be practical.

Black screen on PSX emulation

Hi folks,
The issue i'm representing regards the PSX emulation.
I've added the PSX BIOS files into OpenEmu, and some games too (cue + bin). Double click on the game that i want to start and the emulation goes, but it immediately freezes into a black screen and nothing happens.
Hoping you can help me...

not a problem really, i think i'm just stupid, but I need help...

First of all, i have to apologize about my english, I'm from Spain. So if it is difficult to read it, please don't be scared!

I know that it's not a real issue, but i've been trying to find a place to expose my problem and i couldn't find it.

I installed OpenEmu v1.0.4 and everything was great. Recently I tried with the experimental version and I was in shock when i saw that i had to complete some things manually. I tried with Sony Playstation games and I put the three archives needed in BIOS folder (scph5500.BIN, scph5501.BIN and scph5502.BIN). http://postimg.org/image/hozdnqu03/

I ran the game and it worked! I felt like a hacker (I'm not used to do those things). But I realized that i couldn't save states so i look throughout internet and i saw that maybe I should change my mednafen core. Here's come the problem.

I downloaded the latest version as I could see in a comment (http://postimg.org/image/d1tblz6n7/), and I downloaded just the big file (http://postimg.org/image/7t2w1udlv/). I replaced it in the CORE folder (http://postimg.org/image/9m5sq5ysj/) and I drag the CORE file to the program too(I can't remember why and even in what order).

Watever… I ran again the game but nothing happens… No new windows, no advices… nothing. As if I never ran the game. It looks like the core was well installed (http://postimg.org/image/ucjqdzyar/) (http://postimg.org/image/5xbicxzdv/), but it doesn't work anymore. I downloaded another game but the result was the same.

Then I realized that having just 2 games in Playstation One folder, in all games folder there were some clones and I don't know why (http://postimg.org/image/4byqp7e23/). When I tried to ran those clones an advice told me that there is no core to ran those games and check if I'm connected to internet (but damn! I'm always connected!).

I reset presets writing that in terminal app: "defaults delete org.openemu.OpenEmu". But it didn't work.

Now I don't know what to do…

any idea?

ps4 controller auto-mapping for virtual boy

not a biggie, by any stretch (and forgive me if this should be an issue under umbrella openemu (please feel free to smack me and move this),

BUT,

the right d-pad doesn't map automatically when using a (genuine) ps4 controller. other than that, everything else is great.

(mapping does work, just, not automatically. i'm putting it on the right analog, as most would, i think.)

PSX PAL scanline settings

Hi,

Curious to know why the PSX PAL scanline settings (from psx.slstartp and psx.slendp) aren't actually set, considering they're referenced with suggested values of 14 and 275.

Was this done for idealogical reasons?

Thanks

(feature request) WonderSwan User Setting

there're Mednafen Commands that allow users to set Blood type, Birthday, Sex,Name and so on, such as "wswan.name".
Is there a way to access these settings through OpenEmu? If so where can I do this?
WonderSwan game titles do have features that use these references to generate different in-game stats, and I'd really appreciate that if that's possible.
Thanks in advance!
