Ok, so I disassembled the file that I think has the loading routines for MCGA
sprites with Cutter
([https://github.com/radareorg/cutter)](https://github.com/radareorg/cutter\)),
but I do not have enough experience to read the assembly code. Can someone give
me some hints/pointer of what is going on in the function below?
The binary is DOS 16-bit MZ format:
fcn.00000000 (int arg_22h);
; arg int arg_22h @ bp+0x22
0000:0000 inc si
0000:0001 and byte [0x9521], al
0000:0005 and word [bx], sp
0000:0007 and dl, byte [arg_22h]
0000:000a xor word [bp + si], sp
0000:000c pushaw
0000:000d and bh, byte [bx - 0x32de]
0000:0011 and al, byte [di - 0x70dd]
0000:0015 and bp, word [si - 0x33dd]
0000:0019 and si, bp
0000:001b and cx, word [si + 0x25]
0000:001e loop 0x45
0000:0020 cld
0000:0021 and ax, 0x27e9
0000:0024 push di
0000:0025 sub byte [bp + si - 0x26d8], bl
0000:0029 sub byte [bp + si], bl
0000:002b sub word [bx + 0x29], bp
0000:002e ret
Run
By the way, I am trying to remake the game in Nim, that is why I am posting
this here.
