64bit version works under Ubuntu 18.04.1 LTS
32bit version does not work.  Running 'ldd' on the binary shows:
$ ldd Space32
   not a dynamic executable
EDIT:  I installed 'gcc-multilib' to provide additional 32bit support, and now ldd shows:
p$ ldd Space32
   linux-gate.so.1 (0xf7ee7000)
   librt.so.1 => /lib32/librt.so.1 (0xf7ec3000)
   libdl.so.2 => /lib32/libdl.so.2 (0xf7ebe000)
   libc.so.6 => /lib32/libc.so.6 (0xf7ce5000)
   libpthread.so.0 => /lib32/libpthread.so.0 (0xf7cc6000)
   libm.so.6 => /lib32/libm.so.6 (0xf7bfb000)
   libgcc_s.so.1 => /usr/lib32/libgcc_s.so.1 (0xf7bdd000)
   /lib/ld-linux.so.2 (0xf7ee9000)
Just missing ALSA at this point...
EDIT2:  Well, I broke my VM trying to install the 32bit ALSA libraries.  So it's a no go.  Luckily, I was able to revert the VM using a snapshot I took just before trying.
