Says to use RMAPS Sqlite (I do this and it works fine in the latest version of Locus Map).
MOBAC supports many DB's now:

As does Locas Map:

Is there a better DB to use in Locus Map now than RMaps SQLite? RMaps SQLite has limitations (as described on the MOBAC page).
The guide is 14 years old and I am just wondering if there is a newer recommendation now?
You could try the standardized .mbtiles format, but I think the advantages/limitations are similar to DB RMAPS.
