melonRA Changelog:
Additions and changes
There's a new and more concise settings window which shows all categories of settings in the same window without having to close and open them separately.
The name of the game is shown in the window title now, as well as its icon in the taskbar.
"Hybrid Single" as a new screen layout mode, literally the same as Hybrid, but without the mirroring of the top screen. (Perfect for dyslexic people, like me! :D)
New Time Played and Last Played columns on the game list.
New option to mark games as "Favorite" (it shows with a little heart besides the title, same place as the mastery and game settings cog) and a new tab for all favorite games.
The ability to make a desktop shortcut for any game, which uses the actual icon of the ROM.
Thumbnails for every save state slot.
New option to resume where you left off last session. (Found in Interface Settings)
New Rewind hotkey, must be enabled also in Interface Settings alongside the amount of seconds you can rewind back to.
Trimmed the executable so its a smaller download overall.
Smaller changes: Privacy policies updated, fixed the overlay text where it was showing icons that the font didn't support, updated to the latest commit of melonDS.
Netplay (Experimental)
Under the "Experimental" tab next to Help, you're gonna be able to create a peer-to-peer Netplay lobby with any game from your list, as long as they are matching ROM files across all players. The host player keeps the save files in games which use them.
Use your public IP address shown in the tab (hidden by default), or send an invite over Discord via Rich Presence to have other players join your room. Make note that this last option also shows your public IP address as the host! So only play with trusted friends.
Adjust your input delay (buffer), or use the chat, which will appear in the in-game overlay.
Your name can be changed from here or from the Firmware Settings (which already lets you choose a color, and birthday for games that use that.)
Please notice that, this is experimental. And also that every game works differently. You might have to traverse different menus or get to any certain point to start playing in local multiplayer (which this emulates), Download Play (single-cart) versions of local multiplayer are not supported as of now.
If it doesn't work, try opening the ports you are using in the menus in your routers' settings.
