bn6f-modding's Issues

Uncover and Document the m4a engine. MMBN Uses it

develop execution entrypoint onPWM

This'll be great for logic that executes for some time once per frame, but then automatically deactivates for some time before it reactivates itself!

Add patch for mmbn6g - S Code.gba and

Fix glitchy graphics in chips present when applying latest mods

develop code entry point mode: onEvent and onState

onEvent would trigger on a change in some RAM value, while onState would trigger on a change and when the RAM value matches some constant!

develop code entry point mode: onTimer

For now, onTimer would have a specified number of frames to count down from. It will execute once evert N number of frames. Technically, though, I am not 100% positive the injection is executed once a frame. It is very close, though, or maybe even faster. So this code will be defined as executing once every N turns.

Hook somehow leads to crash when Jacking in to PavilonComp3

Redirect all injections so that no game data is DELETED

develop malloc_api.asm

This should have a linked list of malloced variables. As well as some other datastructure, or perhaps some sort of format that keeps track of the actual data each node points to.

Slinker: Automate ldscript management with hooks, repointing and redirecting functions/data

The ldscript has to be manually modified whenever you want to add logic or data in an arbitrary location.
Enter the Slinker! Its purpose it to automate management of relinking functions and data from binaries! This will make linking data and functions from ROM into separate files a more slinky task

Here's a list of commands defined in the Slinker script (*.sls files):
link(sub_084A0000) ; this will obtain the function sub_084A0000, export it into sub_084A0000.s, and
; modify the ldscript to link it at location 0x084A0000 when compiling! If the function
; has any xrefs, intermediate symbols will be created for them so all function calls/data
; references work as expected!
intercept(sub_084A0000, 0x08900000) ; this will add a hook at location 0x084A0000 and longjump to
; 0x08900000, where it will redo overwritten logic. A file incpt__sub_084A0000.s will be created
; and linked for implementing intercepting logic.
redirect(sub_084A0000, 0x08900000) ; this is like intercept, except the function returns right after the
; interception. additionally, the whole logic of the function is written at redir__sub_084A0000.s
link_m(moduleName) ; this is like link, except it includes ALL functions that start with
;'moduleName_'. Instead of seperate .s files, they are included in one file: 'moduleName.s'
intercept_m(moduleName, 0x08900000)
redirect_m(moduleName, 0x08900000)

Add S code hack patch for MMBN6F

When printing, a random character appears at the end when invoking chatbox engine

Developing py module: GameFile

This should encapsulate a file within the ROM, so that operations can be defined on it such as disassembling it.
