BASIC XE source code#

BASIC_XE_4.2-1_master_with_DOS_2.0D.atr ; please use with OSS MAC/65; Yotta-thanks to all who help us here
BASIC_XE_4.2-2_slave_with_DOS_2.0D.atr ; please use with OSS MAC/65; Yotta-thanks to all who help us here

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.

Thank you so much Tomasz 'Kr0tki' Krasuski for the info in building the runtime, we owe you so much. :-)))
