Changing instruction that was misidentified in IDA Pro

Question

I am trying to compare a source code to a disassembled version of a Sega Genesis (68000 processor) game. I ran the binary through IDA Pro to disassemble it, and when I was going through the code and comparing it to the source code, I noticed that IDA Pro's disassembler labeled some instructions improperly. Is there a way to manually correct it? As it is, I cannot compile the disassembled code, because an error regarding that instruction will come up.

IDA Pro identifies the code as the following:

Here is the hex view:

The hex code is -
01 3C 00 1E 4E 75

The correct instructions should be:

btst d0, #%00011110
rts

Here is a description of the BTST instruction:

Additional Information:

Here is the function in the source code:

Findhittype ;look for type of swing (forhand or backhand)
;input d0 = launch dir
;ouput  beq forhand
;   bne backhand
    neg d0
    add facedir(a3),d0
    and #7,d0
    btst    #3,attribute(a3)
    beq .1
    btst    d0,#%11110000
    rts
.1
    btst    d0,#%00011110
    rts

Here is the function in IDA Pro:
