Hello. I know the post and the game are already "old," but I would like to clarify a few issues, if possible.
Even when following the procedure to import the SMB3 MLB 23 Team Pack 1.0.0 using the Team Tool and overwriting the teams as instructed in the Team Tool, the modifications do not appear in SMB3 — in fact, when I go through the procedure, whenever I try to access the customization menu, the game closes on its own, without any error screen or anything like that.
When I import the pack, sometimes a file (database.sqlite) is generated. Do I need to place this file in a specific folder? Which file or files are generated/modified during the pack import? Besides the import, is there any other step that needs to be done for the modifications to work?
