Sound Files Editing (VCE)

[llm]

my dosbox extension for hooking the drv load+drv calling prototype works!
very few changes to dosbox staging needed to get it working +-45min

that means: i can trace all function calls from stunts into the sound driver (all drivers contain a equal jump-table with 23 functions - but only a few are needed for the driver to work - it seem like a generic interface with serveral features)

my github dosbox-staging fork branch: main_stunts_tests
commit: https://github.com/LowLevelMahn/dosbox-staging/commit/3604bcd5de0e6c4a188807f35b94088abbd51f08
main code: https://github.com/LowLevelMahn/dosbox-staging/blob/3604bcd5de0e6c4a188807f35b94088abbd51f08/src/_stunts/_stunts.cpp

dosbox detects the stunts game.exe start and hooks the drv function call tsub00 - the driver init - nothing more so far

how to build:
1. VS2019 community edition (or VS2022) is needed to build under windows, or any not too old debian/ubuntu
2. clone my dosbox staging fork: https://github.com/LowLevelMahn/dosbox-staging
3. checkout main_stunts_tests branch
4. build sln file .\vs\dosbox.sln
(everything should build out of the box)

[llm]

i've did a quick trace with the MT15.DRV

all tsub[NR] names are the functions from the public driver interface (the 23 functions in the jump table)
in my C-Port all the public functions are currently called c_tsub[NR] - just named by the order they appear in the jump-table
(buts is mostly know what these functions do - very simple C-Code in my port)

Code Select Expand


tsub0 called 1 -> is driver init
tsub1 called 1 -> only calls tsub2 -> driver shutdown
tsub2 called 1 -> reset everything, silence
tsub3 called 76
tsub4 called 101
tsub5 called 74 -> empty implementation (called by Stunts but not needed by the MT15.DRV)
tsub6 called 6
tsub7 called 4
tsub8 called 2
tsub10 called 16
tsub11 called 6
tsub13 called 947
tsub16 called 581 -> empty implementation (called by Stunts but not needed by the MT15.DRV)
tsub21 called 1
tsub22 called 1


find for example "tsub0" in my MT15.DRV project

attached is a full log of getting to the game menu and then exit to DOS
this trace contains all data sent to the driver so you would hear the stunts sounds/music if i could replay this trace with the same timing

[llm]

btw: this type of tracing is possible for every stunts function or code part - if its relevant for understanding what stunts is doing etc.

Well,I can kinda follow what you are doing. But this is to advanced for me.
I did find a code part where the track is loaded. It seems to be a sequence of multiple passes per tile. Maybe there are clues about collision data hidden there.

the implementation itself is easy if one knows the dosbox/16bit code internas a little
but the stunts related code (offsets etc.) needs stunts knowledge from reversing

it sometimes helps to see the data live going through the functions for analysis - my tracer is something like that
debugging step by step isn't always the best way understanding it clearly
