Hey thanks for sharing! Looks like a Pacman-inspired game?
I cannot play it (in cpcec). It loads, animates “press fire to play” but I cannot get past it.
If I run cpcec with the firmware cartridge I can see that I have correctly enabled joystick: cursor keys show arrows and X and Z show uppercase X and Z. And Burnin’ Rubber accepts buttons 1 and 2.
But “Ronald in the maze” in the same emulation setup gets stuck at the animated “press fire to play”.
