Famicom | AV Mod

I really had nothing better to do since the kids are asleep, so I took a tour around the house and tried the 80sFreak modded Famicom that I own:







no NTSC support , just b/w picture:






In order of appearance: Philips, LG, Samsung, Sanyo and Comet.

 

Any chance that we can keep the bickering private?

I'm not really that interested in whether a famicom modded by 80s freak works on a CRT monitor or not.. It's not really adding anything to the thread is it?

 

Not it does not help discussion, like comments similar to "I could not make <insert name here> 's way of modding work, surely he is a clueless person sent from hell to torment me" do not help , but my reply does prove a point: something works

 

You can post as many pictures as you like, just because it works for you, doesn't mean it works for everyone, same goes for the Nintendo method, but I haven't seen or heard any evidence that it does not work.

But you know what, believe what you like. It's supposedly a free world.

I was just arguing the validity of the method as a universal solution, not whether his premodded systems work at all

 

Can you not sort it out between yourselves? Because I don't think that anyone else is really that interested in who has the best working amp, one guy is working off a guide that somebody else wrote and the other owns a premodded console, it's pretty childish.

 

I'm not trying to bicker or compete for the best working amp
just pointing out that the method clearly does not work for everybody and that insulting the ability of other people you don't know just because they disagree with a particular method is unfair.


I apologise to the OP if my temper got the better of me but i just felt the mud slinging directed at anyone and everyone who dares contest the validity of a particular method was uncalled for and unfair and the suggestion that anybody who disagrees with 80sfreak is clearly useless at modding caught me on a bad day.

At the end of the day it's just a lot of fuss over a capacitor value

 

You actually did this at the post you edited 2 minutes ago. The one you have right now is way more tempered and omits all references to 80sFreak. You wondered what's so wrong with him that he can't accept his way is "flawed" and that it's only a capacitor that costs more than the 220uF one you use.
Hence my replies. But I hold no hard feelings towards anyone. Without some fiery discussions things get boring
At any rate, best of luck to anyone no matter what he choses to build.

 

I wasn't going to reply again but you have taken my words out of context a bit there I never asked what was wrong with him, I just didn't understand why he was so quick to dismiss any criticism in this post http://www.famicomworld.com/forum/index.php?PHPSESSID=23db2nrub6mdl1nj2nriudmg12&topic=9084.0. nd rather than listening to calpis' valid criticism just called him butthurt and suggested that he didn't know anything about electronics.
I perhaps did not word it quite how it was meant but I have been pretty sleep deprived as of late.

Once again sorry matisfaction, I'll piss off now and promise only to contribute to this thread if it is useful

 

I don't see the point about arguing over a guide and schematic that 80s freak didn't even write himself, could be a mistake, who knows? but if what you've built or bought works for you then that's all that matters really, enjoy your AV famicoms : )

 

Yes, back on topic, do all of you try to mod HVC-CPU-GPM-02 boards?

 

Mine is indeed one of those, why do you ask?

 

Just in case someone had a HVC-CPU-07 or previous , since the mod is different on those boards... it's easy to get caught up in the discussion and try the wrong one...

 

It's only notably different if you choose to use the transistor which is already on the board. As the transistor you use doesn't really make any difference, it seems easier to just use a new one, it also makes it easier to reverse the mod should I ever happen to fancy using the RF box (even though the rf frequency isn't supported by either of my TVs)
Other than that, the 5v is in a slightly different place but only barely
The sound is a bit different between the two revisions I believe, but i just grabbed it off the pin which goes into the rf box, seemed easiest to find.

 

Man, I'm glad I got a Twin Fami instead.

 

I'm using a new transistor, I'm getting video from "VIDEO" on the board and not pin 21 as I don't want to mess around with the PPU in case I break something.

But as you can see from the pics I posted, I've managed to get a really good image with a couple of minute changes, you can notice jailbars but only if you put your nose up to the screen, they are very faint indeed... looks great on my Sony but I've not tried the amp with the samsung or the LG TVs... I think I've got a good setup here, ill post more details after more testing.

I'm starting to think that I should have gone for the twin fami myself :highly_amused:

 

And miss out on experiencing the unexpectedly volatile famicom modding community, I can't imagine why


It sounds like my jailbars are a bit more severe than yours. They don't bother me massively but I had been toying with the idea of threading copper tape under the ppu rather than desoldering the whole thing as copper tape on ebay doesn't seem too pricey. But I'm worried that threading it under might be a stupid idea for reasons I have not yet considered, i have been a little bit all over the place as of late.

 

^ if you get a 10$ desoldering iron on eBay you can easily desolder the ppu, it's not a big deal... just practice on something else first
My -07 board uses the onboard transistor + copper shielding, before I saw the picture quality it produced I was biased against anything that was inferior to RGB. Everything I own is rgb enabled one way or another but on the famicom I can't really see a reason to not have it composite. Sure you get some junkies but it's nothing bad really...

 

It's not an issue of difficulty, it's more an issue of time and effort, time particularly since I started writing my dissertation yesterday.
Threading it under doesn't seem like it would have any detrimental effects as far as i can tell and would take all of about 30 seconds. There's a possibility of slightly less effective shielding but my jailbars are pretty mild anyway.

Also I totally agree about picture quality, aside from the jailbars it's a pretty damn good composite picture, nicer looking than the composite from the nes that's for sure

 

I was surprised how good the picture quality is, even better if you have a decent tv. I still don't think that you can beat crt for oldschool gaming though...

 

VIDEO and pin 21 are not the same point, VIDEO has already passed through the onboard transistor and is shifted up by 2 resistors. You can and should solder the PNP's base to pin 21 (don't lift it), it negligibly disrupts the existing circuit and will improve the accuracy of your composite output.
