No README? Did you try to use it? GBA ExpLoader is very easy to use, I presume this is easy too.
About GBA ExpLoader (from its README):
Quote
With this program, you can run GBA games in SLOT1 flash cards through SLOT2 expansion pack.
If your SLOT1 flash card supports soft reset, you can use it as "Rumble Pak" or "Memory Expansion Pak".
Supported SLOT2 expansion pack is "3in1 Expansion Pack", "EZ4 lite-delux" and "EWIN EXPANSION PAK(2in1)". "NOR mode" and "Rumble Pak" function is enabled only in "3in1 Expansion Pack".
