All those maprom tools for accelerators try to map the original physical ROM that sits in the sockets into RAM.
The ROM-Updates of OS 3.5/3.9 do the same but also modifiy the ROM by replaceing some parts with newer Versions.
After that you have two different ROM-Images in RAM that do collide and cause a reset.
So you either leave remapollo, when useing the ROM-Update of OS 3.5/3.9 as it is useless anyway, or you keep remapollo that maps Kick 3.1 and leave the ROM-Update by either set the option skipromupdate or deleting the ROM-Update file alltogether.
