How to play [single-player game] forcibly [online battle]

The other day, I held a pseudo online competition for a free-indie Windows game I created in 2004, with three participants, including the author, using a slightly special one-player golf game.

Since the game itself doesn't have an online battle function, it was literally a "forcibly" pseudo online battle. This turned out to be surprisingly good, so I tried to make it knowledgeable so that people who want to do the same thing can reproduce it.

* I tried the game screen sharing function of "Discord" at first, but my game (made with Delphi) was not compatible with the sharing function, so I used the following method.

■ Pseudo online matchmaking techniques
- Use "TeamViewer", a conference tool with a desktop screen sharing function.
- After playing one hole, the participant passes the screen sharing rights to the next player.
- All players play all 9 holes in turn, and the winner is decided by the resultant score.
- Detailed communication is done in the Discord channel.

I think it's a little hard to imagine, so here are some videos taken by participants.

The following is a modified version of the manual described in the "Discord" channel for participants.

There are a lot of pitfalls around the voice and it looks complicated when you read the text, but if you try it out with multiple people while communicating in Discord, it's a lot easier than it sounds. 
If you're looking for a one-player game and want to compete with each other online, this is the place to go!

■ Required Skills
- Install/uninstall applications on the Internet.
- You can change the settings and volume mixer in the Windows control panel.
- You have the passion to realize the pseudo-meeting even if you have to go through the following tedious steps

-----------------------------------------------
[3] Screen sharing and player switching
-----------------------------------------------
(1) Enter a conference with "Conference ID".
- The organizer creates a meeting by clicking on "Presentation" under "Start Meeting" in TeamViewer, and shares the meeting ID with the participants, which is a number starting with "m".

- Participants enter the number starting with "m" given by the organizer in the "Meeting ID" field of "TeamViewer".
- Enter your nickname in the "Name" field and click "Join the Meeting".
* Please arrange your PC screen in advance, and close the ones you don't want to project.

(2) Start 1D GOLF and Mirage.
- Select "1D GOLF" from "Select Window" in "Shinkiro".
- Execute with [Magnification] set to [250%].
- The "1D GOLF" screen is enlarged and displayed.
* The mouse cursor to operate "1D GOLF" is a large black "pseudo cursor".

(3) Play one hole at a time in order.
- When notified of a presenter's nomination, please take over.
- Confirm that the screen is shared on the "TeamViewer" meeting screen displayed on the right side of the screen.

(4) Handing over the presenters
- Finish shopping at the end of one hole.
- Click on the "▼" button to the right of the next player's name in the "TeamViewer" meeting screen.
- Select "Nominate the presenter" and pass the authority

(5) Repeat until the end of the course.
