@DamienD

I think that it is pretty important (and for Rygar conversion thread) to understand how Arcade work and how Amiga work so please make another topic.

So 68000 in CPS never read graphics or sound data from ROM but only "order" to video and sound hardware what and how they should draw/play. This is somehow similar to e.g. how Amigas 68000 setting custom chips (blitter, agnus, paula...)?

192 KB VRAM in CPS is used to compose background layer?

Anyway, quite clever system

how much did cost ROM vs RAM back in 80s and 90s?

I found how Metal Slug for NeoGeo compose display (somebody spread graphics to layers): [ Show youtube player ] - but I am not sure how much NeoGeo is different from CPS...
