+rbairos Posted January 24, 2018 Share Posted January 24, 2018 (edited) Okay, Ive taken my previous simulations, and converted them to streaming 6507 kernel code, by recompiling thestella emulator with a different system::peek() function, that streams KB's of data for each frame of the movie.The kernel is (6 sprites + 5 colors) x 2 interleaved columns. One sound channel is updated each scan line.The color/bw switch works.The reset switch starts playing from the beginning.The select switch jumps forward about 30 seconds and pauses.Fire toggles pause/play.Left/Right is backward/forward twice speed.The kernel never branches, or JSR's, but has occasional JMPs to keep the PC in the first 1K.Memory fetches to the next 1K encode the switch/joystick/fire information.Eventually this will go into custom hardware that should work on any system, though ZackAttack is working on a Harmony version that employs bus stuffing to get the full choice of colors per sprite. test3.mov Edited January 24, 2018 by rbairos 4 Quote Link to comment Share on other sites More sharing options...
