The game SPONCON is a twin stick, top down run and gun. You have to shoot everyone you can and photograph their corpses to earn money from your sponsor, Allgoods. With money you can buy healing packs and upgrades from the Allgoods online store. For sound, the closest thing I could think for the restraints, aside from a regular pc speaker beep, was an emulation of the Covox Sound Master chip which consisted of 3 channels of square wave audio with an option for white noise.
So yes, for this soundtrack only 3 notes could be played at a time. The sound restraints are similar to the chip that came standard in your NES but the NES had four sound channels. One was only for triangle waves and another was only for noise. Either way, I'm very proud of this soundtrack I got together in about 11 days. A few of the riffs were intended for the next Super Famicom release but this project was more enticing. I hope you like it.
