I also have a Targa 64+. When I adjusting Gamma, I got results similar to yours. I discovered that contrast and brightness controls make a difference, the Tconfig program for the Targa allows gamma correction, and some VTR's have built in Gamma. So… Try to run from the framebuffer directly to the NTSC monitor, thus eliminating any VTR gamma correction. Then check TCONFIG to make certain it is NOT gamma correcting. Then try to adjust 3DS gamma to get the grey squares to match up. Play with brightness and contrast on the monitor and you may detect a little difference too. Let the forum know how you make out. I'm not completely satisfied that I've got gamma working, and I'm sure more people will run into the same problems.
