well. the smaller one is air-core, it probably dosent have enough inductance. is the larger one air or iron core? i think everyone used something with some sort of ferrous core, which increases the inductance by something on the order of 1000 times.
also, whats the 'chainsaw intro' (never played that game...). some people have had problems with screen distortion related to loud noises coming out of the speakers.

the small green ones are RF chokes, they're used usually to isolate RF and DC signals. The highest i've seen one rated for is 1amp, so extended use on a N64 might not be good...or it could be fine, who knows
What I have shown you is reality. What you remember, that is the illusion.

If the choke is just on the line from the battery to the regulator input then the current draw shouldn't be anywhere near 1 amp (unless of course the 3.3V line is drawing almost 2 amps, in which case you probably have bigger issues than lines on the screen ).codeman wrote:the small green ones are RF chokes, they're used usually to isolate RF and DC signals.

As for the lines, probably the easiest (surefire) way to see if it's sound related is to disconnect the audio channels. You could also try another game and see what happens.
yeah, i guess you're right. After a quick test/calculation the TI PTH08080 has a relationship of I_input ~= 0.63*I_load for a 3.3v output and 7.2v input. Anyway, I just checked jameco real quick and the highest current choke they have is 495mA, and that was for a really small inductance of 0.68uH...if their labeling and stuff is correct, they tend to be off sometimes. I wouldnt use a choke if I ever got the ambition to make an N64p...
