urchlay 88108e44f0 Traps now work. Had to be done in the M6502 class, not System. Unfortunately, there's no way to trap a memory access before it happens. Unlike breakpoints, traps can occur in mid-instruction. We can't stop the 6502 in mid-instruction, and wouldn't want to if we could (for one thing there's no way to continue from that point). This means that, when you hit a trap, the current instruction is the one after the one that triggered the trap. (This is different from a breakpoint: when you hit a breakpoint, the current instruction will be the one at the breakpoint, which hasn't executed yet). git-svn-id: svn://svn.code.sf.net/p/stella/code/trunk@538 8b62c5a3-ac7e-4cc8-8f21-d9a121418aba	2005-06-21 05:00:46 +00:00

urchlay 88108e44f0 Traps now work. Had to be done in the M6502 class, not System.

Unfortunately, there's no way to trap a memory access before it happens.
Unlike breakpoints, traps can occur in mid-instruction. We can't stop
the 6502 in mid-instruction, and wouldn't want to if we could (for one
thing there's no way to continue from that point). This means that, when
you hit a trap, the current instruction is the one *after* the one that
triggered the trap. (This is different from a breakpoint: when you hit
a breakpoint, the current instruction will be the one at the breakpoint,
which hasn't executed yet).
