(SOLVED) 41CL - DOUBLE HEPAX ACCESS and MMU CONFIG

HePaX Module Owner's Manual, Volume 1, Page 65.

Quote:Don’t use the READROM or WRTROM functions to read or write blocks that are used by the HEPAX file system.
Files under the file system should be transferred using HREADFL and HWRTFL.

I have not verified yet, but I am assuming for now that the READROM/WRTROM are modifying the checksum part of the ROM image and in doing so corrupting HePaX RAM pages.

Hint:

Quote:If you get a CHKSUM ERR message, this means that the data on the mass storage medium has been disrupted.
