    Catch_me_not:     ldr r0, =00007015
                    bl    LoadVariable
                    cmp r0, #0x01
                    bne return_to_normal
                    ldrb r0, [r0]
                    cmp r0, #0x1
                    bne return_to_normal
                    ldr r1, battleFlags
                    ldr r1, [r1]
                    ldr r0, afterGhostAddr
                    bx r0
     
    return_to_normal:    ldr r1, battleFlags
                        ldr r1, [r1]
                        ldr r0, ghostCheckAddr
                        bx r0
     
    battleFlags:    .word 0x02022b4c
    afterGhostAddr: .word 0x0802d461
    ghostCheckAddr:    .word 0x0802d457
     
     
    LoadVariable:    ldr r1, ld_Var_addr
                    bx r1
    ld_Var_addr:    .word 0x0806e569
    All the underlined code is what's throwing the code off. The value returned by the variable loader is the value to compare right after. After that, loading from R0 would be loading from address 1, a BIOS address. That address value (if even loaded) will most likely not be 1, so the second check fails.
    That second check is used only on the "address reading" version of the code. Clean it off, and it should work.
