 * Mystic Warrior (c) 1993 Konami
 * Metamorphic Force (c) 1993 Konami
 * Violent Storm (c) 1993 Konami
 * Martial Champion (c) 1993 Konami
 * Gaiapolis (c) 1993 Konami
 * Ultimate Battler Dadandarn!! (c) 1993 Konami
 *
 * Driver by R. Belmont, Phil Stroffolino, Acho Tang, and Nicola Salmoria.
 * Assists from Olivier Galibert, Brian Troha, The Guru, and Yasuhiro Ogawa.
 *
 * These games are the "pre-GX" boards, combining features of the previous
 * line of hardware begun with Xexex and those of the future 32-bit System
 * GX (notably 5 bit per pixel graphics, the powerful K055555 mixer/priority
 * encoder, and K054338 alpha blend engine from System GX are used).
 *
 * Game status:
 * - All games are playable with sound and correct colors.
 * - Metamorphic Force's intro needs alpha blended sprites.
