Title: Space Invaders: Get Even (スペースインベーダーゲットイーヴン ~逆襲のスペースインベーダー~)
Platform: Wii
Region: USA
Undub: audio swap
Today we are proud to present the first ever WiiWare undub. For this announcement we have chosen Taito's excellent take on an old classic, Space Invaders: Get Even. Not surprisingly, Square Enix quickly turned this $5 download into a $20 one by releasing three separate pay-for-play stage packs, all of which come with separate voice files. Let's go through this undub step by step.
To undub the game, you need the wads of both the U.S. and the Japanese version of the game. You will also need the following tools: 1) bfgr wadtools, which include wadpacker and wadunpacker; 2) U8 Tools by gally, and 3) common-key.bin
Once you have all the tools, follow these steps to undub the main game.
1) Copy common-key.bin to your bfgr wadtools directory
2) Extract the wads with wadunpacker. For each wad, you will get eight .app archives (0 through 7), as well as .cert, .tik, .tmd...
