Originally combining 4 PWM channels by hand, it fell very out of sync and I gave up, so instead I wrote a tool to do it for me. With only few days to go dor the actual contest deadline, I wanted to port Chaotix music. He also ported the Sonic 3D sound effects, not shown on the ROM itself. Nat The Porcupine helped me a lot with corrections and all the sound effects, because now they sound great and correct. Since porting everything from S3K and modifying AMPS to work with S3K, I already had the knowledge to port Sobic 3D stuff, which I did in a few days. I wanted to show off AMPS a little more this year by filling it with lots of music from various games. You can thank me for making it slightly more usable. Oh boy what a mess!Дeapite all this fun stuff, I made it work, qnd of course committed the updates back to skdisasm. Special stages were a mess of poorly or mistakenly documented addresses.

I also had to document palette rotation scripts entirely to make them dynamically update palette addresses. Even then, it was really difficult moving bits about to get a continuous block of RAM large enough to actually house the data, and fixing any glitches that came from this. Because I needed to make room for the sound engines in RAM, I had to sort these issues out before I was able to make this space available. Some RAM addresses were not equated, none of the music was equated, there were several mistakes splattered around the disassembly that prevented me from installing AMPS. The disassembly was severely lacking in support for this kind of work.

Porting AMPS to Sonic 3 & Knuckles was one of the most difficult games to port.

A lot of this stuff is still work in progress, so expect sound issues and general bugs! For more ranting and raving about the project, see the text after credits. In total, there are 95 music tracks in here! I spent a lot of time setting all this up, including some time spent actually working on the disassembly because of a few issues with it. AMPS is designed to be compatible with all different SMPS sound engines to a reasonable extent, so any music can be ported nearly perfectly! This ROM hack provides custom music edits on top of the Sonic 3 & Knuckles and Sonic 3D sound tracks. AMPS is based on SMPS sound engines (Sonic games use different variations of SMPS), but improves upon them. AMPS provides very clean sample playback on the Mega Drive, courtesy of the Dual PCM sample driver. AMPS is a sound engine designed to have a lot of useful features, fix bugs and do it while being less demanding on the hardware. AMPS in Sonic 3 & Knuckles is more or less what the title says: I've added AMPS to Sonic 3 & Knuckles.
