Preload a6 with $dff096 instead of $dff0a0 #8

Closed roger-wetzel closed 2 years ago

Salut Arnaud

LightSpeedPlayer.asm: If a6 is preloaded with $dff096 instead of $dff0a0 then the code size would be reduced by 2 bytes and a few cycles could be saved during one tick/frame.

line 105: move.w d1,$96-$a0(a6) then becomes move.w d1,(a6)

Am I right with this?

Best regards Roger (Depeche/Spreadpoint)

Hi! you're right, 4 cycles win! But $dff0a0 is mainly for "insane" version. LightSpeedPlayer.asm is more the generic version. I prefer keep $dff0a0 for all versions (more coherent)

Ok. I understand that you want to keep it that way.
