Under the Microscope: Virtual Golf

Hey, didn’t I already cover this game? Yes, but I missed some things in the first article. I’m taking a mulligan.

As I mentioned last time:

Like Actua Golf, this game requires your players to be “pros” to play in the Pro level tournaments. If you try to play as an amateur, you’ll be asked for a password.

It turns out that you don’t have to mess around with passwords to turn your players pro: just name the first one MOM and they’ll all be upgraded.

The code that checks for this is located at 06028854 in the Saturn PAL version. The relevant function has logic like this (pseudo-Python adapted from Ghidra’s decompilation):

if (
    (player_name_06042364[0] == 'M') and
    (player_name_06042364[1] == 'O') and
    (player_name_06042364[2] == 'M')
):
    for i in range(8):
        pro_status_060431d0[i] = 1

That is, it checks the first three letters of the first player’s name. If they’re MOM, all eight players get their pro status set. Note that only the first three letters get read — you can name your player MOMMY and the cheat will still work.

That isn’t the only special name. Set your name to BOD to control whether the background music plays. Pause the game, then keep holding Start to turn it off and back on. The controls are a little finicky here:

The game checks for this right after it looks for MOM.

Here’s a third special name: PEL makes your player’s golf ball much bigger.

The ball’s normal size is 8 units, but the PEL cheat changes it to 28 units. If you want an even more comically sized ball, this Saturn Action Replay code will let you have one:

I’m not the first to notice that this game checks for special names: this Japanese cheat site lists:

• SPD: Increase shot speed.
• H??K: Double shot distance (question marks are wildcards).

These are indeed present in the game data. The site also lists ?UU?, but I can’t find evidence of that one.

Outro

The cheats above work in both the Saturn and PlayStation versions of Virtual Golf, which are pretty similar to each other. Speaking of the PlayStation version, it’s got an unused screen that looks like it belongs in the Saturn version:

I’ll be back next week with another examination of a Saturn game. Check out my blog for more retro game reverse engineering in the meantime.
