It depends what that is and what you need me to do? :)
I can give out info on coding on retro consoles in C if that is what you need?
And I am happy to provide some tools for converting graphics from .png's to those systems. I have a few command line tools already, posted up on line on my SourceForge page, links for the tools can be found on my YouTube channel 'Retro C Game Programming' for the MegaDrive, Gameboy, Master System and GameGear.
I have some knowledge on the following consoles: PS1, N64, Wii, C64, Vic20, BBC Micro, GameBoy, GameBoy Advanced, Master System, Mega Drive, NES, Super NES, DS, and i do some coding on Linux and Windows using SDL2 / OpenGL. So maybe able to help with topics on them. I am also putting out tutorials on YouTube around 1 a week now and will go through those consoles eventually. I may also put out some retro games on those systems, still not sure if Itch is best for them, but haven't looked at any alternatives.
