+SpiceWare Posted February 2, 2018 Share Posted February 2, 2018 To figure out how things are done, load the game in Stella: Then use the Developer Key COMMAND-<COMMA> on a Mac or ALT-<COMMA> on Linux/Windows to put Stella in Fixed Debug Colors Mode: If you enter the debugger in Stella by hitting ` (left of 1, above TAB) and select the TIA tab you can see what those colors represent: So Chetiry updates the object colors while the scanline goes across the screen (ie: Racing The Beam): BK = Background PF = Playfield P0 = Player 0 P1 = Player 1 BK = Background PF = Playfield P0 = Player 0 P1 = Player 1 BK = Background PF = Playfield (and a small sliver of BL, the ball) The black on the left & right is where VBLANK is turned on in order to prevent the screen from being drawn beyond the left/right of the gameplay area. The setting of VBLANK on the right is 1 pixel late, which the ball is used to hide. This makes the last column of blocks 5 pixels wide instead of 4. You can use the developer key COMMAND-B or ALT-B to turn the ball off and on in order to see why it's being used: Ball ON: Ball OFF: 2 Quote Link to comment Share on other sites More sharing options...

+SpiceWare Posted February 2, 2018 Share Posted February 2, 2018 I have no idea how or what I should do to implemment this as I have no experience with assembly language. It's not that difficult, try working through the interactive Easy 6502 tutorial. If you can follow that, then check out my Collect tutorial.
