To the devs: Have you seen the latest Lakka Release? It has support for the RPi 3 bluetooth, don't know about its speed though, but maybe it's worth to take a look. These are the related commits: https://github.com/libretro/Lakka/commit/25646a66629899b21307c3e6e8a357c5ee7f9200 https://github.com/libretro/Lakka/commit/9fef9cabd3c5b9c934d7d9884c881f34a74d73cf https://github.com/libretro/Lakka/commit/79f5d3ffad08fae9499236081988edf01729edd2 https://github.com/libretro/Lakka/commit/d38f237c46f1f2e907b9294b1b29e96229f53baa https://github.com/libretro/Lakka/commit/c7e93af096f818fb7e797117d8e920a6bad93883

The problem seems to lie in the newly added rewind option, disabling it in the configuration makes Track & Field run again (and maybe others)

Hi, Same problem here, I'm using Recalbox 4.0.0 beta 2 and with MAME 0.78 the game returns to the EmulationStation menu, while MAME4All freezes on boot. Sorry about writing in english, my french knowledge is quite limited
