Mike Pavone |
Use a typedef code_ptr in place of uint8_t * in 68K core to better support host instruction sets with different instruction word sizes. Make x86_68k_options contain a cpu_options so that gen_mem_fun can eventually be shared with the Z80 core.

Added step and step-over debugger commands. step-over is like next except it doesn't follow conditional branches to lower addresses. This makes it useful for advancing to the end of a loop. Also fixed a bug in next introduced by the refactor.

Initial attempt at emulating extended bank area access delays when 68K bus is busy with VDP stuff. Also emulate the extra delay on the second access of a word-wide read to the bank area. Needs work as it seems to break stuff.

The local clone on my laptop got messed up and some changes had not been pushed. This commit represents the status of the working copy from that clone. It unfortunately contains some changes that I did not intend to commit yet, but this seems like the best option at the moment.
