f34b8d4557 * added support for Top Shooter (custom arcade board using modified Genesis hardware)
* added emulation of a few additional unlicensed game copy protections (fixes 777 Casino crashing randomly)
(NB: it appears that most of those unlicensed games were already patched by ROM dumpers, emulating copy protection hardware only for documentation)
