Question About MESSIAH CHIP
 

Can the Messiah chip play games that have been patch for other ways of booting.... EXAMPLE: Can A PS2 with A Messiah chip play games that were patched with a no mod kit?

In principle for all patched games - YES.

My Messiah plays patched games - the only patches I don't have are for the R-mod. But it shoudl work because Messiah takes up the load beyond the boot patch point.
