Compatibility
The mod is compatible with all 1. 30+ game versions. While the main functionality is independent of any vanilla scripts the support for custom hubs requires a patch to vanilla scripts. This patch has to be installed independently of bootstrap mod (bootstrap mod depends on it) and is provided in the files section for a vanilla game installation. However authors of the most popular overhaul mods kindly agreed to incorporate this patch into their mods. In this case the bootstrap vanilla-patch is NOT required to be installed! Check the top sticky forum post to see a compatibility list.
Compatibility - How it works
The mods starts automatically by leveraging a minimal, hidden quest every time a game is opened/loaded. No scripthook, piggybacking of entities or hub layer entities is required thus making the mod future-proof for usage with additional custom hubs.
To add the new menu the mod changes the file
gameplay/gui_new/guirsrc/r4default.guiconfig
To add the worldmap support for custom area hubs the mod changes the files
gameplay/gui_new/guirsrc/r4map.menu
gameplay/gui_new/swf/worldmap/panel_worldmap.redswf (only in Classic version)
All mods which change this file are not compatible with this mod.
