ares v133: MSX2 firmware?

Multi-emulator ares v133 has just been released. One of the things I'd like to try is MSX2 emulation, but I'm having trouble with the correct firmware. I've tried using MSX2.ROM (32 Kb.) and MSX2SUB.ROM (16 Kb.) from other MSX emulators, but all I get is a black screen.

Can anyone provide the correct firmware for this system?
