No.

I have found a few new ROM_CALLs which will be included with Ash 3.1. It
is my plan to update 82-*.TXT, but it wont be before i get Ash 3.1
released.

I am right here, and have been here all the time.

Just find the prog in the VAT, and change the name/type.

Using the code from CR_KHAND will be hard, and it will probably be
incompatible with any future version of CrASH. Besides that you really do
not need to de relocate a program to change a byte in the APD_BUF. If the
source for the game is available it would probably be easier to make a
normal Ash program which changed the code which decreased the number of
lives left to nops.
