lasso.c

0.36RC2 [Phil Stroffolino]


NOTES:

- Unknown CPU speeds (affect game timing)

- Lasso: fire button auto-repeats on high score entry screen (real behavior?)


VIDEO HARDWARE NOTES:

- Every game has 1 256 x 256 tilemap (non scrollable) made of 8 x 8 x 2 tiles, and 16 x 16 x 2 sprites (some games use 32, some more).

- The graphics for tiles and sprites are held inside the same ROMs, but aren't shared between the two:

- The first $100 tiles are for the tilemap, the following $100 are for sprites. This constitutes the first graphics bank. There can be several.

- Lasso has an additional pixel layer (256 x 256 x 1) and a third CPU devoted to drawing into it (the lasso!)

- Wwjgtin has an additional $800 x $400 scrolling tilemap in ROM and $100 more 16 x 16 x 4 tiles for it.

- The colors are static ($40 colors, 2 PROMs) but the background color can be changed at runtime. Wwjgtin can change the last 4 colors (= last palette) too.
