+Currently there are 4 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`)
+- `CRT` - where `BASIC` becames `BASIC_0` and `KERNAL` becames `KERNAL_0`, with additional `BASIC`/`KERNAL` segments are placed on the required cartridge image
 - `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
