I used to create mod in trackers in the 90's, and now I've started
playing around with DefleMask and Mod2PSG2 to create Master System
music VGM's.

Does anyone know if there is any way to patch a Master System
ROM with new music?

Hi rrobertsen,

there has already been a similar topic lately: http://www.smspower.org/forums/viewtopic.php?p=82499

I believe it should answer your question :)

It's not quite the same. You can fairly easily replace the entire music engine, but then you need to replace every song and sound effect.

Thanks, guys :D

I want to replace all songs in Miracle World and use KiddEd to make
it into a completely new game, but it seems I'll have to dedicate lots of time
to figure it out. Unless a new version of KiddEd comes out shortly with
the ability to change out mods that you could create in something like
Mod2PSG2 / DefleMask. Fingers crossed that will be a reality soon.

Calindro, how much should I hope for this in KiddEd in the near future?

Maxim, what would be an algorithm for replacing all songs with original work (and then re-assembling the ROM?) for use on an actual system, if it can be put into a series of steps?

Thanks again!

Step 1: isolate the music engine and data
Step 2: figure out the API. There will be a way to update the sounds and a way to trigger sounds (songs and SFX), maybe more.
Step 3: make the existing calls into the API do the equivalent in your new engine (which can replace the old one in step 1)

The first part is often pretty easy because the sound engine lives in a single bank along with its data, and all calls into that bank are the API. The last part is where it gets hard.

I've already contacted sverx and we're discussing what will be the best way to do it. So there is a possibility of getting this feature in the near future but it all depends on how well it works.

Btw. you said you want to replace all songs. Do you mean music only or sound effects also? Because if the sound engine gets replaced completely you will need to replace the sound effects as well.
