If you do care about performance, or just feel like hacking asm, there
also exists a Linux MIPS port of the OpenJDK template interpreter.
It's mipsel, as I believe the PS2 is, although it was written to
MIPS64, so there might be some instructions used that are not in MIPS
III/IV.  It is available at https://www.reservoir.com/ultraviolet
