Re: SAM Defender - Updated and Improved!
snipped huge list Awesome! I'm amazed you found so many things to improve upon, as I don't remember any real differences from the arcade version. There are still one or two areas left which I could tweak - but I probably won't as they are pretty trivial. Well, until the mood takes me again! ;-) The Williams startup screen was a nice touch too - couldn't help but laugh at that :-) It had to be done! ;-)) I was tempted to add a virtual coin input too - complete with a CREDITS X message along the screen bottom during the attract sequences, like the arcade version. But that would have been taking things a little too far!! * Saving of the ALL TIME GREATEST scores to non-volatile RAM if you have Edwin Blink's Dallas real-time clock interface. I have support for the NVRAM saving in SimCoupe now, but the emulator is still in pieces after a rash of tweaks and enhancements. I'll get you an updated version once it's suitably back together and tidied up, but that might be a little while yet... No problem! I notice you bundle Defender with SimCoupé - which is great! If you could bundle the latest version with future SimCoupé updates that'd be brill... :-) Chris.

Re: SAM Defender - Updated and Improved!
Hi Edwin, Hi Chris, Exellent job ! Maybe now I have a better change on getting a real high score ;-) lol - me too! I was always hopeless at the game! :-) you had me fooled with the crash effect. I though the diskimage was corruped until I saw the initial test message :-) Edwin :-) That's supposed to be a simulation of the RAM test the real coin-op does on start-up! Have a look at the real coin-op version (under MAME) to see what I was trying to achieve. I took on-board what you said about the older Dallas modules only having 64-bytes. Now I do my initial is there a Dallas module there test in address-space than 64-bytes. So it should reject older modules (and resort to defaults) but on the later modules you should have data persistence across Defender boot-ups! Thanks again, Edwin, for testing my initial code! :-) Chris.

Below are a list of the things changed, plus any new features and also a link to where you can get this - finally (probably!) final - version! = List of things changed to match the arcade coin-op: * Hyperspace is now a 25% chance of death on re-entry - was 50% before. * Homing enemies do not home to the hyperspace re-entry position - they did before! * Landers appear in groups of five, as they always have. When you shoot the last Lander in the current world state, the next available group is warped in immediately. Before, you could have an empty world while the counters for the next group timed-out. So, now its never an empty world! :-) * Climbing Landers that once carried a humanoid (which you've now shot!) that reach the top of the screen will now warp in at a random world X position. Before, they would warp in at the same world X position they disappeared at. * Hunting Landers will now pick a new humanoid target if their current target gets captured or destroyed. Before, if their target vanished they would hunt blindly over potential victims and *never* pick them up... Total pants! * Humanoids are now scattered randomly over the planet surface. Before, they were put at a uniformed distance apart - depending on the number of humanoids in the world. * Enemy shots now have a little randomness to their ultimate destination. Before, every shot was deadly accurate to the player's ship. * Swarmers - their logic has received a major overhaul. Before, they fired in any direction using the same shot-logic as the rest of the enemies. They also flew around the player like a swarm of bees. This was bollocks - nowhere near the same as the coin-op original, and something that's annoyed me for years! The coin-op Swarmers will *only* fire when they are flying *toward* the player - they also use a different shot style and sound. This means you can let Swarmers fly past you, quickly turn and chase them in the knowledge that they won't fire at you - providing you keep close to them. They only change direction when they go beyond a certain distance from the player. In SAM Defender it wasn't possible to use this chasing trick... But it is now - as Swarmers now mimic the coin-op. :-) * Upon player death all screen contents are preserved - including any warping enemies and explosion fragments. Before, all fragments and warpers were erased due to the way their engines worked. Not good - and not like the coin-op! Fixed! :-) * Baiters and Mutants now mimic the coin-op more closely - slight changes to their logic. * Background stars now twinkle faster - a closer match to the coin-op's twinkle speed. * Some sound priorities rearranged, to closer match the coin-op. Even though the sound is still shite! ;-) = List of (internal) things changed from the last version: * Faster and more random random number generator. * Faster processing of the linked-list used to handle the world entities. * Optimisations of the sprite engines and scanner dots engine. * Cleaner final stage to the merging Defender logo on the attract mode. No empty block! * Coin-op timing for the appearance/disappearance of the 500 sprite during attract mode. * General removal of redundant code - such as... * Removal of light-pen detection code. I doubt this was needed - how many had a light pen! * High-score table is now 8-slots, and contains the same initials and scores as the coin-op. = List of things removed from the last version: * Initial Persona logo. * Rotating Digital Reality logo As both of these were seen once only - at initial game boot-up - their code and data have been removed, saving around 8k on the final program size! = List of things added to this version: * Coin-op style rug test-pattern during initial game boot-up! As per coin-op power on! * Coin-op style INITIAL TESTS INDICATE UNIT OK message! As per coin-op power on! * An ALL TIME GREATEST high-score table! As per coin-op. * Saving of the ALL TIME GREATEST scores to non-volatile RAM if you have Edwin Blink's Dallas real-time clock interface.
