I'm having difficulties compiling lsnes on Ubuntu 16.10. Basically I know nothing about compiling and the inner workings but have managed to compile several libraries using step-by-step dummy-friendly instructions. Unfortunately the manual.txt included in the source is way too advanced for me. Can someone give pointers in how to successfully compile lsnes? I need it for snes and with lua support.

Thank you all for your input! I didn't find a function 
gui.screenshot_bitmap()
from http://tasvideos.org/Lsnes/LuaFunctions.html#GuiScreenshot Is this the right place? I believe taking a screenshot and saving it each frame might be terribly slow, although I have a decent computer and the resolution of old consoles is not very high. Thanks for the link to Mario-ai, I'll look into it. I come from the machine learning world, and both using pixels and reading game state from memory are interesting options. How do I know where is the current frame stored in the memory?

Hello, I'm an ai developer, and interested in trying my claws in making ai for simple games, such as Super Mario World or even simpler. I would like to extract each frame (like, an array of exact pixel values) of a game to feed it to an analysing script (to utilize computer vision methods and whatnot) and give back a list of inputs to the game. I tried reading BizHawk documentation about Lua scripting, but I didn't find anything related to reading the screen, only drawing on it. Do you have any idea how to accomplish this?
