Great Exploitations - batari Basic 1.1 beta - with DPC+ kernel

[RSS Bot]

It's been nearly four years since the 1.0 release of bB, so it's about time for another. Many things need to be done, but I've gotten over the big hump of letting bB take advantage of special Melody/Harmony features.

 

We developed the DPC+ bankswitching scheme some time ago. DPC+ is based on DPC, the chip in Pitfall II. DPC+ has evolved a bit since its initial release, and the changes will be documented soon.

 

For now, I've finally got a functioning DPC+ kernel in bB. Currently, all kernel setup is done with ordinary 6507 assembly language. This will change as this evolves.

 

Currently, the specs of the kernel essentially combine the best features of the current standard and multisprite kernels, and improve upon both. You get:

 

• Six sprites (one exclusive, five multiplexed, will be increased to 10)
• All sprites have twice the vertical resolution as other bB kernels
• All sprites can be multicolored
• Asymmetric playfield, any resolution
• Multicolored playfield...
