YGO Omega’s database structure will be different than YGOPro. In fact, someone else is currently developing a new database editor program that will be analogous to DataEditorX (DEX). You can make custom cards and custom banlists in it. So Whimsical’s Custom card creator would have to be modified for YGO Omega.
Some of the differences in OmegaDB’s structure includes adding a text table for different languages like ja, ko, fr, it, es, de, and cn. You also have the setid field which will allow people to put their own sets for their custom cards like ABCD-EN05. Then you can simply search for ABCD in the deck editor to find all those cards. We also have the date which allows you to put the release date of a card so you can filter by date. Lastly, we have category which is not the same as how ygopro is using it. We are using it to specify things like Skill Cards, Boss Card, Speed Spells, Action Cards, Rush cards, TCG Errata’s, etc. More will be explained later about this in better documentation.
This launcher was made by one of our developers to help solve problems that people commonly have like firewalls, bad anti-viruses, or lack of Microsoft updates which prevent a player from playing the game. Other third party programs like a custom card makers can be released separately just like how they have been for YGOPro.
