If you are interested in playing an alternative to retro-arch, I recommend biz-hawk. Its a lot more stable and less intrusive. It doesn’t have net-play, but it does have the addition of retro-achievements.
I don’t like retro-arch specifically because of the controller options. Its not lucrative and adapt to the actual key bindings, and its confusing as all hell.
Honestly, I would rather just stick with mednafen but that doesn’t include retro achievements.
I am putting this all here, because yes, it would be nice to see friends and others scores and where we are ranking at within specific games. A little healthy competition, I am not at all complete in my scoring or rankings. By any means, and honestly, I don’t expect to compete with anyone. I just want to beat the games, and this is a good way to get record of that.
If you are interested you can get the emulator at -https://github.com/TASEmulators/BizHawk/releases
there are four files there, choose whether or not you have windows or a Linux operating system. You can grab source code as well, its not necessary, but if you want to look around its there.
https://retroachievements.org -here is where you will need to make an account. If you are looking for me, I go by the username adviseore1.
this little video will you where to add your retro-achievements name and information.
the biggest issue you may encounter is finding the firmware for consoles, I recommend using
https://archive.org/ and searching for the bios/firmware files there.
In a lot of cases you will be able to find one single zip that includes an entire selection of the required consoles.
For example: https://archive.org/details/BizhawkFirmware2.3.1.7z
I do enjoy this emulator, but am at a loss without SSF for the Saturn emulation. Shima did his damndest with that single emulator. Next to only Mednafen.
I am not certain how accurate the Saturn emulation is versus console. But I can contest there is a little significant change in transparency and maybe frame rate.
I can and will expand on this, if necessary. You can message me at my discord -Тревор
