OK....I popped in my newly aquired Capt Tomaday in my 4 slot and started playing. I have noticed , as well as aero fighters, that during game play in dense graphics it lags....now I have heard of this before in this forum........but is it a mother board issue?? Or is it just a game with way more info than what the mother boards where designed to handle.
Peace
Quazi

ps Capt Tomaday is a wacado shooter........

Some games push the Neo Geo to its programming limit. Backgrounds are easy enough with the CHAIN command so it makes for a sweet back surface. Multiple plane scrolling isnt too shabby using the command. Its when you have 10 million shots flying all over the screen and you are running on the 30 Hz interrupt, you have to slow down from moving so many seperate things.

I made that mistake ages ago with Twin Eagle for the NES. If you thought Aero Fighters was bad with the many bullets, trying that bullet stunt on the 8 bit Nintendo...dumb...very dumb....the amount of phone calls wasnt pretty....

Nope..Not that I know of....The above poster Nightmare Tony would have said so as he knows this stuff like the back of his hand..

If anything was to make the games run faster I think that would have to mean"over clocking"..Something I know nothing about.

Blush :) Overclocking would be as the name describes, upping the clock speed. Not sure how that would work on the Neo Geo. The 30Hz interrupt I mentioned is a lbiurary routine called each time which updates the timekeeping clock, does some bookeeping and reads the inputs.

On this one pinball project I am doing right now, I am doing a similar kind of routine as what is called an event loop. Let me throw you what happs in it and compare it to an arcade game loop.

pinball

init variables

LOOP
read/process all inputs
do game logic (rules)
set up and push outputs
goto LOOP



video

init vairables
LOOP
do game logic(rules)
setup and push video
goto LOOP

during the loop, the 30Hz interrupt will jump out to do the various things mentioned abhove.

For my pinball example up above, I will be creating an interrupt, am just rusty as heck and want to get the bugger going asap :)....

The interrupt can be set up to the start of the screen draw, so the logic rules ands things would be done when its not draswing onscreen...

:eek: :( :eek_2: :spock:

I really dont mind the slow down....gives me more time to plot my escape path................. :D
