Instead of Inkey$() use Keystate()... To find the numbers to use for each of the keystates put this code near the top of your main loop...
Set Cursor 0,0
Print Scancode()
...Now, while playing the game, press a key and remember the number that appears at the top left of your screen...For Example, pressing the "A" button give you the number 30... The "UP" key would give you the number 200...
Now just write...
If keystate(200)=1 then [accelerate player 1]
...well... I hope I helped...
To save you some trouble, here are the rest of the keystates...
UP=200 Left=203 Right=205 Down=208
W=17 A=30 D=32 S=31
