Oh, another developer blog! Subscribed!

A couple of questions...

 

1. So, you're planning to flicker to get two 40-pixel sprites?

 

2. I'd like to hear how you plan to fit all the graphics data into 8K! Especially with such large sprites.

1) Yes, 30hz.

2) I have approx. 7850 bytes available for gfx data once the drawing subroutines and bankswitching overhead are taken into account (so far - could probably be optimized further). With ideal packing, that is 1308 lines available split between all animations. If each character is on average 32 scanlines tall (and these are double-height scanlines), that still leaves around 40 frames available to cover all the animations. I expect the real amount will be somewhat less.

 

On bank 0 is an 'animation lookup table' that describes what frames are used in each 'move' and many will be re-used. For example, walking forward or backward uses the same frames, jumping up or up+back is the same frames, flying kick is just a jump with an extra kick frame.

Ah. Thanks. I figured the characters would be much taller. That makes sense.
