To enable building BASIC XE 4.2 for M091 cartridges, a change has to be made in the D1:MASTER2 file: in line 290, change the value of _27128 to 1. Then follow the normal assembly steps. It results in an object file that loads the four banks to the $3000-$6FFF area in the "1M09" order. Retrieving the bank data in a correct order results in an M091 ROM image.\\
