As you may have seen elsewhere, vic was after someone to convert a vectrex game to an arcade platform. I'm doing it to drop into the Galaxian multigame, and probably afterwards a scramble version for Phil's multigame.

Here is the current WIP


I don't chase the robber when it's in powerup mode since the code to handle that situation is not yet present!

it's being written when I'm stuck in hotel rooms as part of my job, better than watching rubbish on the TV!

Well that's great progress, really looks like it has always been an arcade game from back in the day!

Great guns Mike. Have you reversed the game logic or are you going to write it by observation?
Click to expand...

Robber AI was worked out by disassembly of the original code, but I then wrote Z80 code to match the algorithm rather than converting the code.

Random number generator is used for implementing the skill level of the robbers (they get better until level 9, then remain the same) and each robbers move priority order matches the vectrex

random number generator is not seeded on vectrex for each game, so movement will be different from game to game on either platform - so no patterms possible on this! (but I use different random number generator anyway)

Hoover bag size is also taken directly from vectrex, so that stays the same

Where timings were needed, I just used a stopwatch on the game

speed is probably going to be different, since vectrex runs 50hz, galaxian 60hz - although I'm considering speeding everything up at level 10 or so to add extra difficulty anyway

so overall, some things will change, but game play should remain pretty similar (which is the entire point, otherwise I would have just written it from scratch)
