Release id #126927 : Mythos - Battle for Aivanor
Okay, so it's been my dream to have a high-quality adventure game editor on the C-64. Seeing the Mythos preview whetted my appetite for it anew (though I was originally thinking character-based graphics a la NES Zelda.) I understand that precisely-timed DMA delay is how the full-screen multicolor graphics are "scrolled" so there's no memory left for anything else on an unexpanded C64. (Not sure how much CPU time is left either.)
But for the sake of dreaming, what if the hardware was a C128 with a 512K REU? Would there then be enough memory (and CPU time, taking advantage of the REU's DMA) to be able to have working gameplay elements (and sound) as well? What about loading map chunks from fast disk (uIEC preferably,) like the SNES Zelda does when you get to the edge of an area and there's a depack pause? |

The AGSP method in Mythos would infact use less memory than the traditional software bitmap scroll (double buffer) and far less cpu time (although may be unstable on some c64 systems due to the dma-delay usage) gfx data in tile format would only use slightly more ram (for additional color data) on top of d800 |

Not many. But stormlord was an example. |
