*Thunder Force IV - PAL to NTSC-U Region Fix*

The main purpose for this hack is to change the region of the European release of Thunder Force IV from PAL to NTSC-U so that it can be played on original NTSC-U hardware.

Why Sega decided to change the name from "Thunder Force IV" to "Lightening Force" is still a mystery!

Patch a European rom of Thunder Force IV, upload to your favorite flash cart, or build a custom cart, and enjoy!
