The seminal STG title, developed by Raizing, published by Eighting.

Runs on custom hardware derived from the "Toaplan2" chipset, centered around the custom GP9001 graphics controller. The GP9001 offers three scroll planes (BG, FG, and Text) and a double-buffered sprite blitter system. Battle Garegga, like all their GP9001 titles from Mahou Daisakusen onwards, adds a fourth dedicated text tilemap layer made with discrete hardware, superimposed onto the GP9001 output.

For general repair tips, especially color and video related problems, please see the Raizing Toaplan 2 page.
