I got it working yey ! kinda ..
i managed to have tokyo playing fine hacked,it's london that's giving me problems tho for some reason,i went back over all audio and redone them and made new als files and left london out seeing as it's got some boot up music in it,ill keep at the london one and see if i can get it in there too.
the sound effects are all messed up and many radio cutins don't play anymore,it's as if i have broke the game but all i did was change some music,not really sure why this happened.
UPDATE - What i found was that i can change out music AFS files,for instance the older version of msr i have has the full voice.afs but the newer cdi has a smaller dummied voice afs (i think it's dummy as it has many .iso files that have replaced the adx files and no longer produce sound in the game) I can replace with the full version and build and it's fine,however as soon as i edit any of the afs files and edit the adx within the afs and rebuild, even just one track,the games sound effects become broken,i thought at first it may be an iso size issue but now know it's not that,i also thought that maybe some of those adx are needed otherwise the sound effects break but now know that it's not this either as it doesn't matter the music file that i change.
It's either that i am recompiling the afs wrong or that the format of my wave files are wrong,or the conversion from wave back to adx is wrong or possibly something else.
Still trying to find out why and will post back when i try a few things but would appreciate if anyone knows that is happening here to save me time.
update - found that swapping msr audio with other msr audio,example - taking a few adx from london and inserting/replacing with a few in the sanfran adx and saving the afs file also breaks the game meaning that it's not the custom tracks i have that are the problem.
I am now thinking that it may be the DESCRIPTOR cue type file with track listings/size that isn't correct as soon as tracks are changed for aother compatible tracks and then repacked.
I used to use command line tools for extracting and making audio files but started using AFS Explorer,it seems to have more options for inserting and updating afs files but it's still giving me the same problems,this is where i can't go further,i don't know how to use afs explorer,do i need to hex edit in values ? is there a better tool for making a working AFS that won't give me sound effect problems once recompiled,the music DOES work but the game is broken once any afs file is modded in any way - any info help on this part would be great
ok i want to thank you both,amazing work from you both and mrneo you new name should be ~MRNEOLEGEND~ thank you both for all your time with this,a happy chap !
