ColecoVision Games need a throttle #53

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem?
1. play any colecovision game

What is the expected output? What do you see instead?

Expected output is 30-50% slower speed. Instead the game is way too fast on
all cart roms. Unplayable on most games. Cogwheel needs a throttle.

What version of the product are you using? On what operating system?

1.0.3.0.3. Windows XP Pro SP3.

Please provide any additional information below.

Thanks for Cogwheel it's a great program.

Thank you for your bug report. Unfortunately I have not been able to replicate 
the 
problem you mentioned.

Does this affect the emulation of the other systems as well, or is it only with 
the 
ColecoVision emulation? I tried Beamrider using the default settings. This 
played at 
the same speed as the video here - http://www.youtube.com/watch?v=qbRjweZqJCY

What are you comparing the speed to? Is there another emulator that runs the 
game at 
the correct speed that I could use to compare it to myself? One way to slow the 
emulation speed down in Cogwheel is to go into Emulation -> Video standard, 
untick 
"Automatic" and then select "PAL (50Hz)". If you are used to a PAL version of 
the 
ColecoVision then NTSC will indeed run too fast (assuming the game doesn't 
correct 
for PAL/NTSC differences itself). As the ColecoVision was an American console I 
assumed that NTSC was the "correct" rate. The ROM data file 
(ColecoVision.romdata) 
lacks country information, so all games will default to NTSC if left in 
Automatic 
mode.

What refresh rate have you set your monitor to? Cogwheel locks itself to the 
video 
refresh rate and should compensate for different rates automatically. Some 
video 
card control panels allow you to force vsync off - this will confuse the 
timing, so 
make sure that this option hasn't been enabled.

I hope we can sort something out!
