Most everyone knows that the Neo Geo can theoretically reach a maximum of 330 megabits without the need of bankswitching, but why 330? That is such an unusual number. I guess because it's an arcade machine, you could be messed up when it comes to maximum meg count all you want.
A while ago I downloaded a Neo Geo programming document and it might be some help, so I'll be looking for that document now.
I've seen Neo Geo games FAR lower than 330 Megs that had bank switching.
How do you know if a game has bankswitching or not?
330 because the cart is divided into sections - GFX, Sound and Code. I don't know any details... all the maximums of these (without banking) add up 330.
To tell if a game has bank switcher, you look into the cart, if there's more stuff than ROMs then you've got a banker on board (I think...).
Does the Neo Geo's 7 PWM sound channels have their own bus running out the cart slot?, or do they get fed by the Z80? I know the Z80 and the sprite displaying chip have thier own data busses running out the cart slot.
The setup is similiar to NES, left side of the cart for CPU, right for the PPU... its a very very effective setup.
God I love neo carts, if only I could afford them...
The Universe BIOS includes a CRC check or some such and it lists each bank individually as it tests them. Shock Troopers had 2 or 3 banks I think and it was 100+ MEGA POWER. I'll try and post a picture later. If I forget, remind me!Quote:
