These mods will make Revelations floors straight up not work.


Recently, a limit of the Isaac engine was discovered when too many mods are enabled at once (especially big ones), leading to sprites being replaced by black squares or becoming transparent after some gameplay. The specific limit isn't known yet, and it doesn't depend on the machine's performance.

If you get this bug, first try changing the setting "Clear cache every" to "every room" instead of "every level" in the Rev settings. If it doesn't help, try removing some mods and trying again. We and other modders are trying to find a solution at the moment. We still recommend playing with Fiend Folio and other mods if possible, but this limit is hard to work around.


Enchanced Boss Bars won't interact well with Rev bosses.


As Revelations includes MinimapAPI, it is not compatible with most minimap-affecting mods. You can try to use a mod that changes the minimap, but it won't be supported.

Good Trip also won't work, but MinimapAPI includes a similar functionality that can be enabled either via the C-menu (DSS) or via Mod Config Menu if you have it installed.

The standalone version of MinimapAPI is compatible, and is recommended to have for a faster update cycle.


Music Mod Callback (and dependent mods) aren't fully compatible with StageAPI. You can try to use them, but a lot of music triggers won't work.

Music replacing mods (like Excelsior) are supported, just their MMC functionality, if they have any, won't work well.
