Most Recent Changes

--2.9-RCx--

• 2.9 will see Ares64 graduate from experimental, including Ares64's N64DD emulation, the merge of the MAME experiment, new cores for Atari Jaguar/Jaguar CD and TIC-80, and a subframe-capable BSNES.
  It will also replace the two old Lua engines with a new one using KeraLua, meaning the features of Lua 5.2 through 5.4 such as integers will be available.

• Please check here for changes
