Most Recent Changes

--2.10 RC2--

Second candidate build for the upcoming 2.10 release (changes from RC1). New cores:

• Encore (Citra) for 3DS

• PUAE for Amiga

• Stella for Atari2600

• ChannelFHawk

We also updated Genesis-Plus-GX and QuickNES (now called QuickerNES), and made regular updates for several other cores.

A changelog listing all the bugfixes and improvements will come later, but for now you can check the resolved issues and commit history.

--2.10 RC1--

This includes a fully-functional Encore (Citra) and ChannelFHawk. We also have 2 new WIP cores, PUAE and Stella, as well as updated Genplus-gx and QuickNES, and regular updates for several other cores.

• edit: quickerNES won't work on most Windows PCs. You should be able to drop this copy into the dll folder.
