Fixed very-old bug when loading Rocman game. 
This bug existed even on ZXSpectr. It fixes return flags when using tape traps.
Rocman loading screen was shown wrong (having the "any flag loading setting" disabled), but loaded. Enabling that setting crashed the game

Tests:


-copion method:

cp a
scf
ex af,af'
di
call 0562

f' al entrar:
0100 1001
-Z-- P--C

SZ5H3PNC

sera Z y Carry?

-carga normal
F':
0000 0001
---- ---C

-rocman atributos:
F': 69

01101001
SZ5H3PNC
 Z     C

IX=57FF
DE=0301

-al volver de la carga:
AF=8f82
AF'=FF69

F=82
1000 0010
S      N

F'=69
0110 1001
 Z5  3  C

Z probablemente deba ser 0
Rocman encadena la carga con ese flag Z, y luego falla con mi codigo de trap


-rocman bloque siguiente atributos:
A9

1010 1001
        C
