XRacing is an MSX1 game, in a 48KB ROM cartridge format, built to participate in the MSXDev'18 competition ( ).

XRacing is a tribute to a few of the car racing games I loved as a kid. In particular Super Cars ( ), but there are references to many other games like F-1 Spirit (MSX), 4D Sports Driving (Amiga/DOS), and others! The one thing that I set out to do was a top-view car racing game with smooth multidirectional scroll, which was quite a challenge! The final solution I adopted limits significantly the amount of graphic variety in the screen (and that's why levels look a bit empty), but it more than makes up for it allowing smooth scroll, which I think adds a lot to the experience.

XRacing is an arcade-simulation racing game where you play the role of a driver trying to become Formula 1 world champion. To achieve your goal, you will have to first prove you are worthy of driving in Formula 1 though! Before you can compete in Formula 1, you will have to play through two previous seasons: stock cars and endurance cars. Each season being harder than the previous one as your car gets faster and faster, and it's harder to control! You will also have to manage yur cash, as you will have to pay entry fees to every race, and also you will have to save money to buy better cars. Luckily, you have an agent that represents you and can give you some advise.

The following image show the basic elements of the game screen, and the game controls:

Pay special attention to:

  • To complete the game, you will have to beat three seasons: stock cars (4 races), endurance cars (4 races) and Formula 1 cars (7 races)!
  • In the early seasons (specially stock cars), cars are very slow, so you can take most curves at top speed. But as you progress into more advanced categories, and specially in Formula 1, cars are too fast more most curves, and you'll have to slow down.
  • While driving, be sure not to drive recklessly, however, as your car can get damaged. Cars are usually fine and can last for an entire race, but if you drive too fast, or collide too often, your engine, tyres, brakes or chasis might fail! This is usually not a problem, but just be careful with your driving style!
  • Manage your cash: each race has an entry fee, which you have to pay. If you run out of money to pay the entry fee of the next race, it's Game Over! Also, make sure to save enough cash to buy better cars. There are 3 cars you can choose from in each category. You start with the slowest one, and can buy the later ones if you earn enough money. But make sure you do not overspend, and keep enough cash to still pay the next race fee!
  • It's ok not to finish 1st in a race, but if you finish 4th, your agent will get mad and will kick you out (Game Over!)


The game was designed to be played on MSX1 computers with at least 16KB of RAM. I used the Philips VG8020 as the reference machine (since that's the MSX I owned as a kid), but I've tested it in some other machines using OpenMSX v0.14. If you detect an incompatibility, please let me know!
