The mednafen_psx_hw_libretro.dll core is for Sony Playstation, not Sega Saturn. For Sega Saturn you want an associated platform line for Saturn like this:

I've never had any issues with those games needing a specific version. The best place to get the latest is either join the supermodel3 forum and grab the current version there. There is also valuable information for any Sega Model 3 questions you have, as they've probably all be asked before. You can also get the latest versions in their Discord channel if you prefer that.

Windows dual screen setup does create issue for emulation set ups, that's for sure. When possible try to run TP games at the same resolution as your desktop. You may need to get some patches for some games. You may also need a 3rd party tool like Display Fusion or Dual Monitor Tools to help keep specific apps to specific windows and positions.

For completeness it should also be mentioned the changes in the Games.xml that work with these changes as well. Since Lost World cabinets came in 2 different light gun models, you can set which type in Games.xml under the applicable rom section. or Both will work with either device (once calibrated in game), but the analog_gun version shows crosshairs while the gun version doesn't. (The gun version originally only worked with CRT based displays and position couldn't be tracked except when the trigger was pulled using a brief screen flash.)

As long as they appear as joysticks, using the custom controller file to set the joystick order should work.

That makes much more sense now, thanks. Are you arcade joysticks seen as joysticks or do they use a encoder like an iPac and are mapped to keyboard inputs?

My guess is when importing individual ROMs the full path to the rom is sent to MAME. When using the full MAME set importer it's relying on the rom path being set in the mame.ini correctly and only passing the rom name. Just a hunch as I don't use the full MAME set importer and have a curated list on roms I import.

Yes some of them are preset, but at one point during TP versions some of them changed and had to be updated. Editting them in the RL GUI should update the ini. Yup. Has to match the game name LB passes to RL. Great. 👍

You can set up specific stable ID controller files and pass this file to mame on startup to change the order. MAME stable ID documentation A couple of things you still have to worry about: Making sure button order between your different controllers matches up. If one controller has a A B C D arrangement, but the other has B A D C, you'll have to still individually change games. Since you'll have to set a custom launch command, you'll have to do that for all the games needed. You might be able to use playlist and bulk edit to make it easier. I'm not 100% sure I understand what you mean here. What and/or how are your controllers different for player 1 and player 2 in 4 player games? Need to know more information as using your 6 button controllers as player 1 and player 2 and than the other controllers as player 3 and player 4 is obviously a lot easier and pretty much little work. Just not getting the reasoning. ☺️

What exactly was the issue you are having? Did you set up the per game settings and specifically set up the window TP waits for before switching from the startup screens?

MAME support for the Apple 2 series is fantastic. My guess from the limited information is you downloaded the Software Lists package but your still missing the BIOS/Device roms MAME needs. The software lists are the actual disk images, cartridges, etc that run on a system. MAME still needs some core files to emulate the machine. My guess is you are missing these files still. I don't use Software lists for Apple 2, but trying to run it from a command prompt will tell you exactly which files are missing. Something like

For future reference, that's an important detail to include when asking for help. I'm glad you have a solution you are OK with, but I was curious at this point. I downloaded the gens 2.11 with large ROM support hack and it starts games just fine directly from LB as well. If you're still interested, maybe post some checksums (CRC32) of your rom and gens.exe and we can eliminate any issues there. Just curious, if you start a Windows Powershell or command prompt and start the emulator passing the file path to a ROM, does it work? Something like this in Powershell (from the gens emulator directory):

Well played with this some more and got some interesting results. The second patch is the problem one. No sound for me on that one with Genesis GX core in Retroarch. Neither patched version will even load for me using Gens 2.14. (What version are you using) I added Gens emulator to LB and when loading ROMs they didn't start for me either. Then I remembered I was testing with my current library which are all zipped. (Core supported) I turned on the LB option to extract archives first and now Gens emulator booted directly into the games. So looking back on your posts you said you tried all the options but maybe you didn't get them all right at the same time. Don't remove quotes and extract archives if using archives ARE requirements. Also, from your screenshot, the option to extract ROM archives has a solid square, not a check mark. This leads me to think that you have multiple platforms listed for using the Gens emulator and not all have the same extract ROM archives option enabled or disabled. Are you 100% sure it's not enabled/disabled as need for you ROMs? Bottom line is LB can launch a ROM directly in Gens emulator without command line options. It's just a matter of finding the configuration issue.

Can you provide more information on these issues (like a link) and is it up to date information? I have no way to know what to listen for, and I only know MK by name and look, but I downloaded the hack and ran it with Retroarch and didn't notice audio issues. (Not to say there isn't any, I just don't know what they are.)

I had the same issue and got tired of dealing with Retroarch so switched to the Flycast standalone emulator for 2 player games. When you say hide the cursor, are you talking about the system cursor or the in game crosshairs?

Possibly a design decision. Most people using LB aren't using as a cataloging system for unused games so Platform hiding isn't often requested feature. (Just a guess) To accomplish the same thing, just bulk edit all the games in the platform and set to hide and the platform will hide as well. To see them again, just change view option to show hidden and than bulk edit back.

BTW, on the RocketLauncher forums there is an updated module for Teknoparrot that has the newest games and settings ready to go.

Teknoparrot is the only system I still use RocketLauncher for. It has active window scanning for just the thing you want. Additionally, when possible I use JConfig over Teknoparrot when possible as it launches dramatically faster and LB's startup screens work well enough.

To be honest, I don't use this globally but core specific, so each core can use different keys. (Not just remapped) The mappings are the same but it's added to the core override in Retroarch -> config -> <corename>. As you've noted above, the default mapping falls apart in several situations. I started with an Xarcade, but upgraded it to an iPac, but it's essentially the same still. When I started, Retroarch naming for the actual controller and the Retropad was confusing so manipulating the config files was easier, but it has improved greatly and possibly GUI based might work just as easy now. The important thing is grasping the concept of the virtual Retropad. A few issues I found: The default mapping of using the left ALT key caused some issues with some tools and some emulators. I changed it to H. Some cores, (Like Stella for Atari 2600) have lots of system buttons like difficulty switches which can only be mapped to player 1 in Retroarch. For an arcade stick set up this was ugly, and by adjusting the keys like above, you could map player2 COIN and START to player 1 inputs for selecting in Retroarch. It's a little confusing but works perfectly. On some games, you just need analog inputs or triggers, etc so you might to use another controller for these games/platforms. When you use these key overrides you can set to nul to disable the keys. This way someone playing on a controller isn't affected when the kids hit cabinet buttons. As skizzosjt mentions, getting your Xarcade mapped to the Retropad first is essential. I have disabled most Retroarch hotkeys but if I remember correctly, I thought [ and ] were mapped to functions in Retroarch, so you may want to make sure so those are mapped on Player 2.

Sounds like you want to set the keys that are mapped to the virtual Retropad, not remap controls. You can map the virtual buttons to your keyboard keys if you want in the the settings > input > player 1 binds menu. (Save configuration after) You can also manually do the same in your retroarch.cfg file. I have different keys set for different cores so I manually add the keys I want in Retroarch -> config -> core name. You're looking for entries like this:

I have this exact same setup and it works great. I used to have the Mag-Stick Plus and never cared for it. I found the manual switching wasn't practical for visitors on my machine. With either the Servo stick or the Mag-Stick, although 4-way is an improvement, these aren't as good as a true 4-way stick. Having said that I don't have any issues using the Servo-stick in 4-way mode, but more demanding "power" users might. Also, some or the Arcade cores like mame2003plus and FBNeo have some improvements to help with 4-way mode as well.

Just start MAME without a rom, go to Custom filter in menu that opens, pick the two filters Working CHD required

No. Unfortunately my entire library is converted, that was just a new CUE/BIN I downloaded to double check. There is an interesting discussion on the MAME github about chdman and Dreamcast images here. That discussion leads to some scripts here that might help the original OP in converting some CUEs to workable GDIs for conversion.

I just meant faulty in the information needed for CHDMAN to convert isn't sufficient. Basic ones I had didn't convert but the following example converted fine:
