Not sure, but I think I found something wrong.

Code:

0x00(4) - Offset to String (relative to 0x00 in String Relocation Group) 

I think it should be

Code:

0x00(4) - Offset to String (relative to 0x08 in SYMB Header) 

as skipping A818 bytes from 0x0 in String Relocation Group takes you to "d_player_versus_common". Skipping from 0x08 in SYMB Header takes you to "snd_player_system" instead (and there are no strings before it), which seems to make more sense.

*fixed*

Thanks for spotting that, didn't test it but I don't doubt that I would have made a mistake like that, it was pretty hectic writing all those relocation groups.

[Diddy Kong]

anything else i should know about this? cuz i wanna greatly extend a sound to put steve erkal in the "GO" and "time" announcers

[VILE]

I don't think you realise that there are thousands (or high hundreds) of offsets to edit. Unless you write a program for this, it is virtually impossible.

[DarkPikachu]

this will be useful *copys*

well not impossible...
just take an ungodly amount of time,
and a critical amount of brain power to make it work right... heh

That's why I said it was "virtually" impossible

The amount of time to edit 1 sound would be more than that of the time it would take to write  a BRSAR extracting and compiling program.

i also came here to look because jaklub uploaded a video with sonic's announcer rediculously long without speed-up or slow-down

@mods

may I suggest a move to the programming board

and if better, create a sub-board "Notes"
