There are some other emulators that might work better than Basilisk II depending on what exactly you need.
There's Cockatrice which is a fork of Basilisk II. Has better networking, sound, and support for SCSI disks, but dropped some other features (don't remember which ones).
PCE can emulate a Mac 128K/512K/Plus/SE or Mac Classic, but not a Quadra.
MESS can also emulate a various models (including Mac IIci and LCIII) but again not the Quadra.
PCE and MESS have more faithful emulation than Basilisk, but they don't emulate later models.
