+karri Posted May 31, 2022 Share Posted May 31, 2022 Due to my desire to use larger ROM's I did change the directory and cart logic on my old cc65 compiler. In the old code the block field was 8 bit and it was followed by an unused byte that was usually $88 0r $00. In the current version the block field is 16 bits long. The high byte contains the highest address bits of the ROM. These bits are driven by the CART1 read strobe and AUDIN. Old projects need to set the content of this unused byte to 0. And it would be good to define the block field in the directory to be a .word instead of a .byte Quote Link to comment Share on other sites More sharing options...
