ALS 1.95: Screen overlay
Simone 'saimo' Bevilacqua has provided "ALS", the AMOS Layers System, a way to layer individual screens of AMOS Professional, specifying the order, colors and degree of translucency (video). The whole thing is written in AMOS and is therefore available as a source code library.
About this version Bevilacqua wrote: "This is the last version that supports also OCS and ECS. ALS v2 will be AGA-only. The reason is that supporting all the chipset requires lots of additional code and also slows down execution in many places, while functionality is still very limited on OCS and ECS due to the fact that they offer only 6 bitplanes and 32 color registers. ALS is much more useful on AGA, so it makes sense to have a leaner and faster version for that chipset. Also, I decided to postpone the release of Follix to after ALS v2 is done, so that the game can benefit from it." Changes:
- Optimized ALS_SET_DISPLAY_COLORS_RANGE_FROM_PALETTE[] and ALS_SET_DISPLAY_COLORS_RANGE_FROM_PALETTE_RANGE[] a little bit.
- Removed wrong comment from ALS_SET_DISPLAY_COLORS_RANGE_FROM_PALETTE[].
