![]() ![]() Level themes now sprang to life with a wide breadth of real and synthesized instruments, allowing composers to fully realize their ambitions in terms of game sound design. The revelatory transition from the Mega Drive’s YM2612 six-channel FM sound chip to the SEGA CD’s Redbook audio was a technical boon for game composers and a cultural boon for consumers. What an impression the opening themes for Sonic CD must have made on audiences who’ve only ever played video games with chip-tune audio. “Toot-toot Sonic warrior, deep in space and mind.” ![]() Some frames still don't match between the two, but they do match up in many places and pretty much end at the same time.“If you’re strong, you can fly, you can reach the other side of the rainbow.” Look at this comparison between the Sega Genesis Intro vs the actual game's intro on the PC/XB1/PS4/ and Switch. So I really think the difference between them is the fact that the Genesis version is using XGM composed audio instead of the actual music from the game. The sega CD version is the video ripped to FMV format for the sega CD and the audio was ripped from the actual game as well. So it is quite possible that the original video playback was right on the mark in regards to actual playback length, but the newly composed audio music for it may not be and that is evident in the videos since the entire things ends as you said.later than the sega CD vesion does. ![]() Now.having said that, the audio is a composed version of the original audio from the game. So different versions of the rom have been made to adjust the video playback to get it more in sync with the audio. Originally the video playback of the Genesis version was too fast as compared to the audio. Interesting you say this.here is what was done on this. ![]() Is the animation on the Sega CD too fast, or is the animation on the Genesis too slow? During all the opening credits the Genesis gets upwards of a full second ahead, but by the time you see Sonic, Knuckles, and Tails together the Sega CD has caught up, and it keeps pulling ahead. Since I haven't seen the actual intro to Sonic Mania (holding out for the PC vesion since I don't have any current consoles), I don't know which one is right, but the Genesis version clearly plays back slower than the Sega CD version. BTW.there has been like 4 other updates since I first posted it, with each being better sounding, more optimized and more in sync. Eitherway, this intro video is technically superior to the SonicCD intro in that is has more colors with the same amount of frames I believe and while SonicCD is using redbook audio and that is excellent for the time, it is still quite impressive to see the XGM driver being used in this demo with a musical rendition composed here for the intro music in sync like this. Way over my head, but I think he is trying to get it to nearly half in the end. Matteus is looking at other methods to see if further compression is possible by using less tiles to create the overall images etc. Takes up a full 4Mb of cart size, so pretty much a cart of this would only contain the intro sequence shown here. One of my friends had it hooked up to his good speaker system and it felt unreal at the time - like the future was happening When that came out I almost passed out from excitement. Kinda reminds me of how I was awed by the Sonic CD intro (although that also had the CD-audio). Very cool! I wonder how much cartridge storage that took up. ![]()
