not really.
mame is a _machine code_ emulator, disassembler and debugger.
spim is an _assembly_ emulator and debugger.

assembly from disassembled _machine code_ can be used for reverse
engineering, detecting bugs on assemblers/compilers, ...
assembly _source code_ has meaningful labels, comments... like [0];
but you wont get it by reverse engineering itself, although you can
write it later.

spim isn't a tool for reverse engineering, although it can help after
using a disassembler.

but this question was already addressed by mame itself supporting
current architectures.
ignoring the trademark, for the purposes of this discussion:
a mame version with only support for current architectures (i386, z80,
...) would be like qemu.
a mame version with only support for obsolete architectures with some
free software depending on it would be like wine.
a mame version with only support for obsolete architectures without
free software depending on it would be like ndiswrapper.
