Summary	08788: othunder: Is the game supposed to be in Mono?
Description	Okay, so, i'm confused. I know for version 0.197, from Mameinfo i readed this: - 0.197: Changed Operation Thunderbolt to mono speaker, as shown on schematics and verified on real board [Guru]. Added ADC0808 A/D Converter to Operation Thunderbolt. Use MCFG_SCREEN_VBLANK_CALLBACK instead of MCFG_CPU_VBLANK_INT [Dirk Best]. Changed MC68000 CPU1 clock speed to 12MHz. I can understand the "verified" thing but, the game it's still having the Stereo Separation from Machine Configuration, not to mention, from Taito Legends, i know it's a compilation of Taito games that are emulated even from the console ports but there, the game it's having the Stereo sound. Here's a video from Taito Legends, recorded from the PS2 hardware: This is nothing like a major thing or anything, i'm just confused as i marked this as "Trivial" so, if the game is still suposted to be in Mono, just feel free to close this report.
