Hello everyone,

I saw a section on this website called "Controller Patches" and I wonder if there is a patch (or someone can do, hehe!) of the game OutRun Europe to exchange Nitro by acceleration button (up button? It has no logic...). I love this game, but it's hard to play with original settings buttons.

Greetings from Spain!

Then you'll hit the nitro button by accident all the time...

This game uses some fairly verbose code to map controller input bits to an in-memory representation. We can therefore swap (all uses of) Up and Button 2 by changing this mapping.

Master System version:

ROM[0293e] = 6f
ROM[0295c] = 47

Game Gear versions:

ROM[0298a] = 6f
ROM[029a8] = 47

Thanks, but I'm not a computer engineer and I don't know how to modify it. Could you upload the modified rom?

Better to make an IPS, let's hope people can use them easily enough.

Yes , I wish someone could do that patch...

You can create it yourself quite easily. Just load the rom into Emulicious and open the Memory Editor. In there make sure the ROM tab is selected and press CTRL+G. Enter the address specified by Paul (e.g. 29e3) into the box and click ok. You will see the blinking cursor at the location you have entered. There you can type the value specified by Paul (e.g. 6f). Do the same for the other address value pair. When you're done you can press CTRL+S and save the file either as an ips patch by entering a filename with ips extension or directly as patched rom by etering a filename with sms extension.

Done!!! Thanks!!!

I made IPS files and pages:
