Hello stella world... I'm a brand-new list subscriber, it's good to meet you all. About a week ago I `discovered' atari 2600 programming, and have been obsessively coding since... So far, I've got a not-quite-game with a spaceship made of two players, that can be moved around with the joystick, a playfield that's a border around the screen, and a ball (actually a missile) that bounces around, a la pong... nothing special (using the HOR_POS table from David Schweinsberg's droid2.asm and relying heavily on material from Nick's site...) I am having a minor problem with player vertical positioning... not sure if I can explain it properly... when I position the players in the first 30-40 pixels of the display, they appear to be shifted down one scanline (my kernel is 2 scanlines per iteration, low res)... I will post the code as soon as I clean out the huge sections of commented out code and the profanity (cussing at the thing doesn't really help, but I keep doing it anyway...) Unfortunately, the only way I can run my code is with xstella, so my problem may be a bug/issue with the emulator, but I doubt it (the guy who wrote the emulator knows a lot more than I do about the 2600, so it's almost certainly my fault)... The other thing is, I'm using ca65 (from www.cc65.org) for a cross assembler... from reading the archives, it appears that dasm is the standard here. Should I take the time to port my code to dasm before posting it here? Shouldn't take long (minor syntax differences can probably be fixed by a perl script), but I wondered if anyone else is using ca65? I chose it more or less randomly (well, already had it installed, as it's a part of the cc65 cross compiler). Hopefully talk to you soon... B.
