Update: i just noticed someone already succeeded tampering with the game memory in dosbox in this topic. I'm taking notes of all relevant pointers they found.

@dreadnaut yes and no. I can run a dosbox machine with no video output and so my window would be the only interface for the user. I am undecided about replacing the game menus or reusing them at the moment (need to experiment first)

Hello everyone, i recently joined this forum and saw what you guys achieved, which is quite impressive imo.
I am currently doing experiments with the memory of a dosbox container running stunts with the intent of creating something similar: having the unmodified game run in the background while rendering on top of it with a custom engine taking the track elements, cars and camera positions from the game memory.
This is the list of features i am seeking to implement:

• a native game with cars handling faithful to the original
• high resolution rendering
• custom game assets to replace the original ones
• free camera placement

Note that i didn't mention hardware accelerated rendering because i like to craft my own pixels so i am trying to realize an 8-bit palettized software renderer for this purpose

I don't have a working proof of concept yet, at the moment i am mostly experimenting with dosbox and cheat engine. If you have suggestions on other analysis tools that you're using I'd gratefully take note (or maybe they're mentioned in other threads that i still have to read?)
