Waiting to Merge

None

In Progress

• Android (@PwLDev is working on this in a separate repo)
• PS3 (@Fancy2209 is working on this! PS3 Port #469)
• Xbox 360 (@PwLDev is working on this! [WIP] Xbox 360 Port #530)
• Original Xbox (@MikeDev101 is working on this! [WIP] Original Xbox support #540)

Planned

• Libretro core

Potentially

• N64
• PS2
• iOS - Sideloaded
• Dreamcast
• PS5 (Homebrew)
• PalmOS
• Playdate (Definitely possible, but performance is a concern)
• SEGA Saturn
• macOS Versions Older than 10.13
• TI-NSpire
• GP32
• Symbian
• Dingoo (Native)
• Minecraft Server (Using Minestom and JNI) (takes a lot of effort)

Costs Money

• iOS - Officially

Unlikely

• Nokia N-Gage (Supposedly also has really outdated toolchains)
• Palm/HP webOS (Little to no info about toolchains and SDL support)
• Xbox One/X/S via UWP (would not be made by an organization member due to the fact none of us use Windows)

Needs NDA

• Switch (2) - Officially
• Xbox One/X/S - Officially
• PS4 - Officially
• PS5 - Officially

Not Planned

• Standalone kernel (this would require pretty much rewriting the entire engine to use C and not require a standard library)
• TI 84+ CE or older
• GBA or older
• PS1
• Anything older than Windows XP
• BlackBerry 10 Native (Developing and running new apps is pretty much impossible now due to BB signing servers being permanently shut down)
