Extension.cfg(ELFS)

[Stoka543]

Can someone tell me all about extension.cfg. I have gameboy emulator on my s75 and i cannot make extension support for gb and gbc.
My gameboy emulator is in 0:\ZBin\GBA\GAMEBOY.elf and this is the code: "gb:0:\ZBin\GBA\GAMEBOY.elf
gbc:0:\ZBin\GBA\GAMEBOY.elf"
What am i doing wrong?
I tried with Tex editor, Cfg Editor but its the same, the txt,gbc,gb,bcfg files are not usable!

Do you have elfloader 1.8++? So you must run ExtD.elf or ExtDx32.elf

Could you explain it? What should I do? What is ExtD.elf or ExtDx32.elf and where can I find it?
