A real Amiga 500+ 🥰:

Conclusion:

Current:

{m68k_op_and_32_er_d         , 0xf1f8, 0xc080, {  6,   6,   2,   2}},
{m68k_op_or_32_er_d          , 0xf1f8, 0x8080, {  6,   6,   2,   2}},

Correct:

{m68k_op_and_32_er_d         , 0xf1f8, 0xc080, {  8,   6,   2,   2}},
{m68k_op_or_32_er_d          , 0xf1f8, 0x8080, {  8,   6,   2,   2}},

I cannot say anything about the 68010 timing, because I don’t have a real 68010 CPU available.
