                        \ --- Mod: Code removed for Elite-A: ------------------>

\JMP DEEOR              \ Decrypt the main flight code and join the main loop
\
\JMP DEEOR              \ Decrypt the main flight code and start a new game
\
\JMP TT26               \ WRCHV is set to point here by elite-loader.asm, so
\                       \ TT26 is set as the character write routine

\EQUW IRQ1              \ IRQ1V is set to the address in these two bytes by
\                       \ elite-loader3.asm, so IRQ1V points to IRQ1

\                       \ BRBR1 is set as the break handler

                        \ --- And replaced by: -------------------------------->

 JMP RSHIPS             \ Load a new set of ship blueprints, set the space view
                        \ and jump into the main game loop

 PRINT "S% workspace (flight) from ", ~S%, "to ", ~P%-1, "inclusive"

[X]

Configuration variable BRBR1 = &11D5

The address of the main break handler, which BRKV points to as set in elite-loader.asm

[X]

Configuration variable IRQ1 = &114B

The address of the IRQ1 routine that implements the split screen interrupt handler, as set in elite-loader.asm

[X]
