Ciaran Anscomb released the second alpha version of his Dragon 32/64 emulator for the GP32. The changes:

GP32 version now features a virtual keyboard and is slightly faster than the last release. Note: You *do* need to find a Dragon ROM and edit it so it’s just the ROM and no leading bytes. See the README for details. Next release should have a file requester in so you can select from multiple ‘tapes’.
