Overlap, G2f and real Atari machines

What on earth do those games show or prove..?

 

Crownland shows a good A8 style Mario Bros game I think. Add to that the plethora of wonderful A8 scrolling platformers like Spelunker, Cavernia, Black Lamp etc etc

 

Your comment "But in Machine Language impossible" seems redundant

Well, Crownland has the "logic" bug, that the stars were build upon PM graphics and other moving objects have to flicker, while almost all animated basic games use charmode animations to have many animated objects of the same type on the screen.

 

Spelunker and Cavernia I liked very much. But Black Lamp is unappealing.

this is not "logic" bug, Probe multiplexer increase pm objects like interlace (similar to Commando-cartridge, see bullets)

Tebe... MK ment with logic bug that Probe designed the engine to use pms for the stars and not chars...

they assume 160x200 by default simply like we do that they have an "antic e", both untrue...

 

One thing I haven't seen in any product is the use of conflicted priorities to produce the black color. I suppose if you need to use most sprites throughout the screen and can't use gprior mode 0, an extra color -- black can be generated with conflicting priorities.

I think that someone here on Aage mentioned he used the black colour of conflicting priorities in his game (Castle Crisis I think?) but anyway, if I understand it correctly you can get conflicting priority only between player and playfield so you have to use soft sprites with PM overlay and it has it's own restrictions so maybe it's not worth the effort too much.
