The dualopl2 (sbpro1) sound emulation mode doesn't seem to work for the game "Rise of the Dragon". There is only sound on the left channel, the right cheannel is completely silent. The opl2 & opl3 modes work fine (in mono).
This game supports stereo OPL2 sound effects, such as a helicopter flying by from left to right (at the first screen after starting a new game). That is the reason why I would like to run it using the sbpro1/dualopl2 mode. I know this because I played this game originally on a 286 & SB Pro.
The game can be downloaded for free here:
Run install.exe to configure sound to "Sound Blaster".
The game must be started with CPU Cycles to 7500 or less (at least on my PC) for the sound blaster detection to work properly, otherwise only the OPL music works and not the OPL sound effects and sampled sound effects.
