Analysis
Compared to Source 1 this version has a Autostart loader "CTW" added that loads basic program "HTE". HTE shows a screen centered loading message and loads "BT7" at $1000, which shows a full screen petscii loading screen and loads "BIGBIRD". With a small start routine at $1080 the code of the main program is patched:
at $8CEE JSR $973B is replaced by BIT $973B. This routine would display the CBS Software Logo.
at $8D15 JSR $87E1 is replaced by BIT $87E1. This routine would wait after the CBS Software Logo is shown.
at $8610 RTS is patched in. This reduced the wait time of the credits screen, basically skipping it.
