Trash the songs of sonic3D

Why is very hard to port some sonic3D songs? i want to port Green groove 1/2, rusty ruin 3 and rusty ruin 1 to Sonic 2' Clone Driver. But i cannot fix rusty ruin 1. And i cannot fix another songs; i'm facepalmed for this. How to fix this songs?

 

It's difficult because the songs used in Sonic 3D are more large and a bit more advanced.


The main reason why your Rusty Ruin track cannot be ported correctly is because the old SMPS driver in Sonic 1 has a different setting, it's all about the timers, if after a timer, there is yet another timer, the engine will play the last note that was set, in sonic 1's driver, this includes 80 to DF, in Sonic 3D's driver, this includes 81 to DF, 80 is not included as part of a note in Sonic 3D, so it never gets set as the last note that was played, even if it was.


So:


B1 10 10 10 80 10 10 10


In Sonic 1, this will play as:


Note B1


Wait 10 Cyles


Wait 10 Cyles (Play last note B1)


Wait 10 Cyles (Play last note B1)


Note 80 (Rest)


Wait 10 Cyles


Wait 10 Cyles (Play last 80 (Rest))


Wait 10 Cyles (Play last 80 (Rest))


In Sonic 3D, this will play as:


Note B1


Wait 10 Cyles


Wait 10 Cyles (Play last note B1)


Wait 10 Cyles (Play last note B1)


Note 80 (Rest)


Wait 10 Cyles


Wait 10 Cyles (Play last note B1)


Wait 10 Cyles (Play last note B1)


And that's the main reason why you're having trouble porting it, without SMPS knowledge and doing it with a hex editor, your port is going nowhere.

 

hahaha. Ok thanks!!!

 

Was the profanity in the topic title really necessary?

 

Also that Sonic the Hedgehog 's sound engine is SMPS 68k and Sonic 3D Blast is SMPS Z80. =P

I have a feeling you didn't understand a thing what Markey just said. XP


Anyway, while were still talking about Sonic 3D Blast. I have a quick question... This might sound a little strange but... I was wondering, is there a HUGE difference in porting music from Sonic 3 & Knuckles and Sonic 3D Blast? I know how to port music perfectly from Sonic 3 & Knuckles using just a hex editor. But, I've never tried porting music from Sonic 3D Blast yet. So, is there something I should know that is different from porting music from S3&K? Thanks.

 

Yes. My ports of sonic 3 & knuckles are perfect, but for some reason is very difficult to port of Sonic 3D

 

because something like:

Almost never occurs in S3&K, as the sound programmers would have obviously had lacked knowledge of optmization (Or something, not too sure), though the songs in S3D blast are strongly optmized with the above quoted example to save space.

 

Ok. Solved xD


And

No. Sorry for this

 

Why do I have a feeling he's using ESE?

 

I doubt that your ports are perfect if your using tools dude. =P


(And, their not really your ports. The tool did it for you. Give some credit to the author of the tool too.)

Because he is using it. Or using Music Pointer Fixer.

 

Three posts up, I think it's clear that this topic is ready for locking now =P

 

I use the tools for help me in only SOME things. I need to fix manually some PSG, pitch, etc

 

Um, the tools does the whole port for you man. It's not a perfect port I know. You still need to fix the DAC and the pitch of the PSG, maybe some flags and the voices. But honestly, those things are really easy to fix. Using tools is not a bad thing. Hell, I used to use them... =P


But, if you ever want to port from another game other than Sonic lets say... Dangerous Seed. You would need to know how to port songs just by using a Hex editor and knowing how the SMPS Z80 sound engine works. But, It's up to you really... You decide what you want to do.
