my game created by pygame, it is not shown in the ports section

[FUNFUN]

Hello, I am doing a job and I have to put a video game made by myself in the Retropie OS, the video game is already in the ports section with its respective .sh, if I put the command "python /home/pi/RetroPie/roms /ports/Pong.py" the game starts perfectly, but it also doesn't appear when I start retropie, it doesn't appear in the ports section, I also have:
I check the game file extension

Verified directory structure

Verified file permissions

Restarted EmulationStation after making configuration changes

Checked the “Parse Gamelists Only” option.

but it still doesn't work out, if someone can help me, thank you very much, the game created is Pong.

Con la cantidad de foros de RetroPie en inglés, oficiales y no oficiales, ya es casualidad que vengas a este, que está en español :-D
