Moon Shuttle (alternate) for the Dragon

Post by pser1 »

Hello,
lately I found an alternate version of the game "Moon Shuttle" for the CoCo, uploaded by Richard Kelly in the CoCo Facebook group

As it didn't work for the Dragon, I unassembled the binary with F9DASM and then searched for ROM Subroutine calls, I changed them
for the corresponding ones for the Dragon and finally I searched for points where the keyboard was checked, there are seven checks,
but only five of them required patching to use the Dragon keypresses

Once tested, I have put it inside a VDK with a basic loader to make things easier ...
Just mount the disk and issue
RUN"MOONSALT.BIN
or to avoid typing that much just enter
RUN"GO
The game works with keyboard (the four cursor arrows and space) and accepts the left Joystick too ...
Press Break to exit a game and return to the main menu
enjoy!
cheers!

Hello,
I have been requested to try to allow that program to enter native mode if a HD6309 is found.
I have added a new binary to previous VDK named MOONSL63.BIN and the basic is GO3.BAS
enjoy!
