Hi,<br><br>You have a description of memory access instruction format in cpu-all.h, under<br>/* CPU memory access without any memory or io remapping */<br><br>These instructions are defined in softmmu_header.h. If you don&#39;t care too much about performance it will be easier to modify the code written in C (undef ASM_SOFTMMU in 
op.c).<br><br>Regards,<br>Eduardo
