Subject: [stella] does the processor stop during VSYNC? From: Eric Fischer <eric@xxxxxxxxxxxxxxxxxx> Date: Sun, 5 Apr 1998 22:21:08 -0500 (CDT) |
This is probably a really silly question, but I'm still waiting for my Supercharger to arrive in the mail so I haven't been able to test this on a real Atari. When you do a VSYNC, does the processor wait until it's really time for the next frame to begin before processing resumes (like a WSYNC), or does it just send the sync signal to the TV and keep on running regardless of how many scan lines have passed since the last time? I'm hoping it's the former, of course, but I'm guessing it's probably really the latter. The emulator I'm using (Stella 0.7) seems to think any number of scan lines in a frame is fine, but I don't know how much faith I should put in its emulation. By the way, what I'm working on is a flying toasters/fishtank screen-saver sort of thing. After that's all working (it mostly is; I just have some annoying intermittent timing problems to work out), I'm thinking of adding a paddle at the bottom for some weird sort of Air-Sea Battle/Breakout hybrid, maybe with a second player controlling the toasters or fish with a joystick. eric -- Archives (includes files) at http://www.biglist.com/lists/stella/archives/ Unsub & more at http://www.biglist.com/lists/stella/stella.html Don't post pirate BINs to Stellalist.
