How to write games for LG TV?

Question

LG

In general, there is an LG TV (not smart) with the ability to play simple games, as well as run them from a usb drive. That is, purely theoretically, I can write and run something of my own? How to do it?

Games are a kind of archive where you can find, for example, such a manifest.xml:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<app_content>
  <is_system_app>N</is_system_app>
  <app_id>70001</app_id>
  <app_ver>1.0</app_ver>
  <file_size></file_size>
  <file_name>valentine</file_name>
  <exec_arg>L15</exec_arg>
  <icon_large>valentine_icon_large.png</icon_large>
  <icon_small>valentine_icon_small.png</icon_small>
  <string_id></string_id>
  <alias>Valentine</alias>
  <title>Valentine</title>
  <description>Valentine Game</description>
  <sdk_version>2.00.00</sdk_version>
  <platform>m1a</platform>
  <demomode>N</demomode>
</app_content>

Link to the TV, you can also download a couple of games there: https://www.lg.com/kz/support/support-product/lg-3...
