Depending on how your VCS, your TV set and your computer monitor are tuned, the colours displayed by a real VCS might differ a bit from the colours displayed on an emulator. For example PCAE's palette seems to be a bit too dark for most people. But if you want good signal colours, that people can tell apart easily, you should probably stay away from the darkest and the brightest luminances no matter how good they look on your own TV. And also remember that the lowest bit in the colour value has no effect. So %00001111 is the same colour as %00001110. >PAL. It was suggested that I adapt the program to have two color palets, >so that the colors can look better if played on a PAL system. suggestions >for color codes for the above colors? I have no way of testing this. Even PCAE lets you see PAL colours by pressing the F3 key and Z26 shows PAL colours if you start it with the -c1 command line option. Also on http://www.primenet.com/~nickb/atariprg.htm on the tools page there is a little program by me, which shows all 128 VCS colours, if you press the joystick button. This should help you to select nice colours for your game. I'm not quite sure if it is called COLOURS.BIN or COLOURS.PAL, but if it is COLOURS.PAL, you can rename it to COLOURS.BIN, since the .PAL extension is only to make the program start up in PAL mode on PCAE. >though my program has the scan line counting for NTSC, is it still fine >for PAL? Or should I make a different version w/ line counting for PAL? Most PAL TVs should sync nicely to a 60 Hz signal. You just have to make sure that you do an even number of scanlines per frame or the colours will be lost. The first version of VIDSIMON does an even number of scanlines. Stella for DOS shows the number of scanlines for the last frame after you quit the emulator, just in case you want to check that yourself. Or you could send the new version here and we will check the PAL colours for you.
