Instruction: suba.l D0, A0

Test case: sub1l
https://github.com/dirkwhoffmann/vAmigaTS/tree/master/CPU/SUBA/suba1l

Musashi:

Amiga 500+ 🥰:

suba1l_A500+

Conclusion:

{m68k_op_suba_32_d           , 0xf1f8, 0x91c0, {  6,   6,   2,   2}},
{m68k_op_suba_32_a           , 0xf1f8, 0x91c8, {  6,   6,   2,   2}},

must be:

{m68k_op_suba_32_d           , 0xf1f8, 0x91c0, {  8,   6,   2,   2}},
{m68k_op_suba_32_a           , 0xf1f8, 0x91c8, {  8,   6,   2,   2}},

I cannot say anything about 68010 timing.
