Title: N8 Pro FAMICOM + 60-72pin converter + HiDef NES no/corrupted display?
Post by: Revo_Emag on January 28, 2020, 03:44 AM
Just got my N8 Pro FAMICOM ver. and it is awesome! I have 3 Famicom/NES systems and I can use it fine on 2 of them, but not the 3rd. So for reference the 2 that work fine are:
1. AV Famicom w/ Tim W's NESRGB mod.
2. NTSC NES front loader, composite video, blinking light win, Hyperkin and 'My Arcade' branded 60-72 pin adapters.

The one that I can't get to work properly is a NTSC NES top-loader with Kevtris' HiDef NES mod. I can play all my NTSC/J carts fine with my Hyperkin or 'My Arcade' 60-72 pin adapters on that top loader, just not the N8 Pro.

With the Hyperkin adpater it appears to not boot fully. I see the red light come on then flash and go out. Then nothing. Controler is unresponsive.
With the My Arcade adapter it boots, but the screen is covered in random characters and you can't read anything. It seems that the N8 Pro functions, because I can start a game and the graphics seem fine in-game, but the load/save menu and main menu are both unreadable. The HiDef NES's menu is fine during this time too, as a side note.

Oddly both these adapters work fine with the N8 Pro in the front loader. I'm stumped. I assume it's some sort of weird issue between the HiDef NES and the N8 Pro? I've tried all the OS versions from 2.00 to 2.06 as well. All do the same.

Any suggestions? I'd like to use it on that one too, but I'm very happy with it on the AV Famicom.

Thanks for your time!

Menu uses tricky methods for fast rendering, which isn't used in regular games, only some mmc5 games may use similar tricks. Menu rendering require high accuracy from console hardware.  I wonder if Uchuu Keibitai SDF (J) working fine with your hi-def nes.
It could be related to outdated hi-def firmware, make sure yours is updated.

Thanks for the response. I checked and as far as I can tell 3.01 is still the latest HiDef NES firmware which is what I have. I currently don't have another way to run Uchuu Keibitai SDF (J), but if I'll try it when I can.

I just found this thread. I'm having the same issue with the N8 pro and a HiDef NES..

HiDefNES firmware 3.01. I haven't tried the older firmware.

Add another to the list. Same issue as both here and same firmware (3.01) on Hi-Def NES.

I have not actually seen the N8 Pro work yet in mine so I would not know how to start a game as I have never used one. Normal carts work fine. The only other NES I have is a front loader. I have not tried the Famicom N8 Pro in there yet cause I have not had time to take it apart.

Try this OS build: http://krikzz.com/pub/support/var/rc/N8-PRO/EDN8-safe-mode.zip
In this build menu forced to work in safe mode. In this mode menu repaints bit slowly and looks worse but not used any tricks for rendering. I wonder if safe mode will make any differences. My OG analogue nt with hi-def mod works fine without switching to safe mode by the way, i tested on firmware v2.00 and v3.01.

This does not work. I even downgraded my HiDefNES firmware to 2.25. Same result.

With this firmware, I do see some garbled text flash on the screen before it goes black. Here's a video:

It still works just fine using a non-modded NES. But strangely, with this firmware it tells me that I have the PPU bug, which is common on cheap clone consoles.

This is because i forced safe mode which used for such clones.
Same black screen without sd card?

Post by: MadJackHist on February 06, 2020, 03:12 AM
Actually, no. I get the gray "SD Card Not Found" screen..

Hmm...
Title: Re: N8 Pro FAMICOM + 60-72pin converter + HiDef NES no/corrupted display?
Post by: KRIKzz on February 06, 2020, 03:31 AM
Then potentially it can be problem with power supply. Some SD cards may draw large current during initialization or write operations. This impulse may cause system crash if there is not enough power to supply hdmi board, system itself and everdrive. Those "SD Card Not Found" screen has same loading sequence as OS, but it loads from internal flash instead of sd card, if this work then OS should work also.
1. Try to use another sd card if you have any.
2. If possible try to power everdrive via usb cable to check if external powering can makes changes.

Nope, same behavior. I tried a 32gig card from sandisk and one from samsung, both class 10 sdhc u1. Also tried a 128gig samsung class 10 sdhc u3. Also tried formatting the cards using ex-FAT as well as fat32 on the 32gig cards. Also fooled around with the file allocation sizes. And various versions of the os.

Also tried attaching an external battery to the usb port, and tried using a 2 watt usb wall wart (the one used for the SuperNt). Same behavior.

I have ordered a couple of 16gb sd cards, as well as a class 4 one. We'll see how that goes.

What happens if insert sd card right at "SD Card Not Found" screen and push reset?

Post by: crcross on February 06, 2020, 04:31 AM
I changed my power supply to my original NES power supply and it has been much better. It still does not start 100% but it is much more consistent in working but things are very strange.

I am not sure why but, if the console is sitting on my desk it does not work but if I pick it up and hold it so it touches me it works every time and still works after setting it down? No joke. This is with the latest OS and the safe mode one. As strange as it sounds it is true. See video.

I am at a loss here. Maybe some type of RF interference?

No menu problem with good power supply but Mario 2 fds broken. Hope Krikzz fix.

Same. Though it seems to be sporadic without the card inserted. Sometimes it fires right up to the C1 error. Sometimes nothing.

I thought I was onto something when I removed my 8bitdo MES wireless controller adaptor.. but it's the same.

Looking more and more like a power issue. I'm using the OEM power adapter (the one that came with this NES when I bought it in 1991), and nothing.

Am tempted to buy a retroRGB AVS just to see if that works. Haha!

Anyone know if it does?

I have same hyperkin famicom to nes adapter like in your video. Just tried it with unmounted top loader. Guess what? It not working. Then tried with front loader and same thing.

AVS works with latest firmware. Also you need good powering usb cable, otherwise avs may fall in reboot when OS initialization begins. Were discussed here: http://krikzz.com/forum/index.php?topic=9533.15

So maybe it is something about the way I hug it with the Hyperkin adapter lol. I guess I need to just show my NES some love when I want to play until I can get a hold of a better adapter.

Different SD cards had no effect.

Any other ideas on getting this thing to work with the hi def nes?

2. NTSC NES front loader, composite video, blinking light win, Hyperkin and 'My Arcade' branded 60-72 pin adapters.

Wait, the My Arcade adapter works for you? I actually bought two (thinking the first was defective) and neither work with my N8 Pro on any console I've tried... other adapters work fine, though.

Sorry, been away a while and catching up to the thread here.

Wait, the My Arcade adapter works for you? I actually bought two (thinking the first was defective) and neither work with my N8 Pro on any console I've tried... other adapters work fine, though.

Sort of works, but not a good experience. The My Arcade on my top loader w/ HiDefNes will boot the N8 Pro, but the menu display is all messed up. Just garbage characters everywhere, so you can't read anything. If you start a game, the display is fine in-game and seems to play fine too. It's really odd. This might be an obvious question so no offence is meant, but when you use your My Arcade I assume you took it out of the shell since the N8 Pro wont fit. Are you turning the FC carts around to face forward? The My Arcase is the only adapter I've seen where they flipped the top connector so that the label faces forward/up. So they are opposite of the Hyperkin and others.

I just tried the Hyperkin adapter again without the SD card in the N8 Pro on HiDef NES and I do get the gray SD card error C1 screen. Which is something I hadn't tried before.

I've also tried an original NES 10v 1.3A AC power adapter and a Triad 9v 2A DC adapter, USB power to the N8 Pro using a 10W Apple iPad charger, as well as several different SD and SDHC cards and none of that makes a difference.

 :o Well this is certainly interesting.

I tried the Safe-Mode FW Krikzz posted earlier and holy sh*t it works fine on my HiDef Nes top loader with the My Arcade adpater!

Still black screen or no boot with the Hyperkin though.

Also just a side note: I de-soldered the CIC chips from both adapters when this all started. They are completely unneeded for a top loader and my front loader already has one on the Binking Light Win board anyway. I doubt this has anything at all to do with this though, but just mentioning it in case.

Yep I took it out of the shell. I plan on cutting the top of the shell off to allow the larger N8 Pro to fit, and since I'm using it with a top-loader I dont care about that extra bit anyway.

My experience is the same-- messed up menu, but otherwise functional. Sorry I probably should have clarified that in my post. The main reason I wanted this adapter was because it works with Famicom carts facing forwards.

Cool! I'm gonna have to try that later.

I tried it with and without the chip, made no difference to me. Same results on both a top- and front-loader.

From your post it seems the N8 pro has better compatibility with the OG analogue nt. i have the second edition. You think it will work just as well/
Thanks



Try this OS build: http://krikzz.com/pub/support/var/rc/N8-PRO/EDN8-safe-mode.zip
In this build menu forced to work in safe mode. In this mode menu repaints bit slowly and looks worse but not used any tricks for rendering. I wonder if safe mode will make any differences. My OG analogue nt with hi-def mod works fine without switching to safe mode by the way, i tested on firmware v2.00 and v3.01.
