m2c
The most reliable way to get the closest C output to the original source. The decompiler is open source.
Ghidra
A fully-fledged executable analysis tool. It is open source.
You may want to use the [ghidra_psx_ldr https://github.com/lab313ru/ghidra_psx_ldr] plugin, which automatically creates the right memory regions and comes with a way to regonize the right PSY-Q SDK by matching the libraries with their signatures.
The decompiler produces noisy but somewhat reliable output.
IDA Pro
Paid product. A MIPS decompiler was introduced starting from IDA Pro 7.5. The output looks clean but often over-simplified. Certain instructions are completely absent from the output; this is due to the disassembler outputting pseudo-instructions that combine multiple instructions (such as outputting a pseudo instruction for lw from a lui and lw). You may want to use the [psxida https://github.com/lab313ru/psxida/] plugin. Not recommended other than very specific scenario.
You can get around the truncation by going to "Options->General->Analysis->Processor specific analysis options" and unchecking "Simplify instructions".
