Solved virtually all my doubts!!
If you mod a NTSC unit to PAL-M and keep the NTSC PIF you will have B&W video on interlaced video due to a timing problem with the chroma burst. (A good example is the N64 Killer Instinct game)
I need to take a look on my working N64.
Does a list of games that trigger this effect exists?
I don't have much games, I think 10 or so...
And they're becoming quite expensive here!!
PS1 has some special optimizations to make the CXA145 image better:
I'll also check my PS1 I'm not sure if it's PAL-M.
On PSONE I saw only a crystal exchange.
How does the alternating phase behave in these cases?
Again, timing problems with the color burst. They put two 100nf capacitors at strategic spots to reduce that a bit.
I'll do some tests. I think the TecToy's one I have takes the signal direct from the video controller.
They should have modded the main clock on later releases.
But unfortunatelly this causes the freaking "rainbow banding", wich seems to be mostly gone with the crystal.
Basically... PAL-M is a hack and you're better avoiding it like the plague.
Yes, I sure want to!
How hard would be to convert an old TV, if ever practical?
I think I should be asking this on an electronics forum...
Can someone recomend a good one?
Maybe when the analog signal is turned off I should do my parents a favor and convert their TV to NTSC.
Or even better, gift them with a newer LED one!!
Yeah. The colorburst is a marker at a specific time after the hsync pulse to indicate a specific angle or color
Any recommended books that explain these (and other) terms?
This seems to be basic knowledge that I'm missing, and at least on the places I've been reding it only gives me more doubts.
Well I relly feel strange playing retrogames on a LCD TV...
They just don't seem to fit well. It can be the nostalgia that makes me see those things with "pink glases".
Maybe I should be getting used to it, I think CRT TVs will become rare and difficult to mantain.
In 30 years I think most of them will have failed to work, unfortunatelly
So whem (if) I ever got this old, with rheumatism on the fingers, I think old games on CRT TVs will be just histories I will tell to my grandsons...
I didn't saw Joe's post...
I have read that it can be dumped by interrupting the boot process at a certain point and then displaying the contents of the ROM on the TV.
Can it be done with a Gameshark?
I've seem a schematic that could convert a standard Gameshark to a Gameshark pro.
But I just can't find it now
Would be great if the PIF could be exchanged by a microcontroller running it's code.
So a region free N64 would be possible!
