BrMSX emulates the Z80 clock counting, including the extra
waitstate in M1 cycles. It also emulates faithfully the R register.

BrMSX emulates all documented features of TMS9128 and most of the
undocumented ones.

BrMSX emulates all undocumented opcodes of Z80 and almost all of
the undocumented flags (exception are the block-commands, I'm working on
this right now).
I give you a challenge: to make a program that detects if it's
running on BrMSX or a real MSX-1. It's very difficult to make such a
thing!! Of course, please give me a copy of your program if manage to
build one.
Right now, the most safe way to make sure that a program will not
run in BrMSX is to check for MSX2/2+/T-R. These things are not emulated
and will not be in a near future.
