@@ -97,7 +97,7 @@ List of the most important make targets:
Currently there are 3 ROM layouts defined:
- `STD` - with 2 code segments: `BASIC` (`$A000-$E4D2`, where `$C000-$DFFF` is a skip-gap for RAM and I/O area) and `KERNAL` (`$E4D3 - $FFFF`)
- `M65` - where `BASIC` becames `BASIC_0` and `KERNAL` becames `KERNAL_0`, additional segments might be added to the build system in the future; at the moment of writing this document additional 8KB of ROM is defined as `BASIC_1` segment and additional 8KB of ROM is defined as `KERNAL_1` segment
- `M65` - where `BASIC` becames `BASIC_0` and `KERNAL` becames `KERNAL_0`, additional segments might be added to the build system in the future; at the moment of writing this document additional 16KB of ROM is defined as `BASIC_1` segment and additional 8KB of ROM is defined as `KERNAL_1` segment
- `X16` - memory layout for the Commander X16 machine
To check for current ROM layout or code segment use KickAssembler preprocessor defines, like `ROM_LAYOUT_STD`, `ROM_LAYOUT_M65`, `SEGMENT_BASIC`, `SEGMENT_KERNAL_1`.
