Im in the process of writing a clone of universals 1981 arcade game ladybug for the acorn bbc microcomputer
the original arcade game had a Z80 cpu running at 4MHz with 24K of game program in eprom
fast hardware sprites with an extra 16K of eprom dedicated to sprites and game graphics
the bbc computer has a 6502 cpu running at 2MHz
has 32K of ram. 14K used for the bit-mapped screen, 18K remaining for game logic, graphics, sound and music
only 8 colors black, red, green, yellow, blue, magenta, cyan, white are available
no hardware sprites, all graphics must be rendered in software
very basic square wave sound chip
squeezing everything into 18K of space with a slower cpu and software rendering is a great challenge

its all just test code right now, writing and testing the functions required for the final game
