Playing with pixels

Being the old-hardware maniac I am, I bought an MKIII Myth flash card from ic2005.com to play my (regularly bought at flea markets) Master System games without having to keep all the carts around. A nice side-effect of flash carts is that they let you try your own code on game consoles: in short, you can write and play your own games!

I've already done some homebrew console development on Nintendo 64 and SEGA Saturn, but the Master System is a different beast: being older and more limited, high-level languages are out of the question (Well, actually you CAN use a C compiler: see z88dk), so I'll have some fun learning Z80 assembly!

In the meantime, I tried drawing a sample tileset (keeping hardware limitations in mind, and beware: I'm no artist!) for a game idea I have:

And here is a level mockup made with the tileset:

It's set in a weird farm... Will go more in depth describing it some other time, if I can go on developing the idea!
