J'utilise aussi régulièrement VTI, même si les différents bogues des différentes versions (il n'y en a aucune qui marche comme il faut) commencent à me faire ch**r dans tous les sens.
Pour les licences, les voilà:

Clause style XFree86 4.4, incompatible GPL (donc s'il a pris du code de UAE sous GPL en même temps, c'est mal parti), et non-respectée par Rusty Wagner.
cpufunc.cpp:

Notices de droits d'auteur et licence strippées, code apparemment utilisé illégalement. D'après mes recherches, piqué soit de UAE (GPL), soit de MAME (licence plus restrictive).

MAME. Encore une fois, notice de droits d'auteurs et licence strippées.
Et aussi de nombreux autres fichiers (opcode*.cpp par exemple) très probablement pris d'autres projets (MAME?), mais sans aucune trace des auteurs d'origine ni de la licence.

Z80Em. Licence à usage non-commercial seulement, incompatible GPL (donc s'il a pris du code de UAE sous GPL en même temps, c'est mal parti). Pas sûr s'il a respecté la clause des notifications nécessaires pour tout changement.
Au passage, je suspecte le projet MAME duquel il dit avoir repris les cores 68k et Z80 (du moins la version qu'il a prise) de ne pas être en règle avec les licences non plus. Cf. le core 68k pris sur UAE et le core Z80 pris sur Z80em, avec des licences incompatibles entre elles.
Quant à gtktiemu, il est à un stade, hum, imparfait
