OK, I've tested and I get the following :

La première révision présentant le problème est :

(The first release that shows the problem is :)

changeset:   5007:7a4948830aee

summary:     bset.b d0,8(pc) is not a valid 680xx instruction, but an
illegal one

I'll try again with the release 5006 and 5007 to be sure, but it seems
that this 5007 release is the one that slows a lot the new with my effect.


I hardly see how just adding an illegal opcode (that is not used in your test program I guess ?) can slow down the whole cpu emulation ?

If you comment/revert the changes in #5007, does it really speed up your program ?
