A spreadsheet with all details on supported emulators can be found here.

• current versions of Dolphin only have x86_64 and arm8 JIT.
• older versions supported arm7 (xu4 is arm7) but they are no more maintained.
• Dolphin requires a 2Ghz CPU (c2 is maximum 1.9 Ghz).
• in other words, it could be supported, but through an old version, or too slow.

• the Reicast code is not ready for the aarch64 architecture yet.

• the Apple II emulator requires SDL (1) to work.
• the SDL v2 was patched to support the Odroid graphical card, but SDL (1) was not.
