elf2exe

elf2exe writes a linked program out as a PSX-EXE, for a program that is the whole of the machine rather than a Net Yaroze one.

It is the plain conversion: the loadable image and the entry point go into the 2048-byte header and nothing is added. eco2exe exists because a Net Yaroze program is only half a program, and has to be combined with the library the boot disc leaves resident in RAM; a program that brings its own crt0 and drives the hardware itself needs none of that.

$ elf2exe prog.elf MAIN.EXE
created "MAIN.EXE": load=0x80010000 entry=0x80010000 8192 bytes, d00f145ee4fd44f1

The input may be ELF or ECOFF, since only the loadable segments and the entry point are read. --stack-addr sets the stack pointer the BIOS installs before jumping to the entry point, which matters only for a program whose crt0 does not set its own.
