I remember having to work around this when I created an arcade stick with the guts of an old PS1 keyboard. I used an Excel Spreadsheet to map the keys and to figure out which combinations of inputs would result in the least amount of blocking/ghosting in practice. So basically, if you have a two-stick console with 6 buttons for each player, you had to wire it in a way that was impossible for Player 1 to ghost/block Player 2's keys (and vice versa). So when you found a combination that ghosted/blocked, you'd just map them to opposite directions on the same side since it's not possible to press UP+DOWN or LEFT+RIGHT at the same time on a joystick.
