Hi Def NES Firmware Updating

[Promethium144]

I purchased a Hi Def NES kit when they were first released and went about the job of modding my console. I am very experienced with working with electronics so there was no hesitation that I could do the job right. The mod on the hardware side of things went very well and by and large worked very well.

 

I have however encountered an issue I am hoping someone here can help me with solving. With the console powered on after about 3 min or so the graphics will begin to glitch, I believe this to be a known issue with the PAL RP2c07-0 PPU with the v2.25 farmwear, the obvious solution is to update the firmware, I have a genuine Everdrive N8 and have loaded the update rom and initiated the update through the Hi Def NES menu but no matter what I do the integrity check fails and the firmware does not update. I have tried 3 different cart connectors including a new one, cleaned the edge connectors, replaced the CPU and PPU replaced the CPU and PPU RAM and re-seated connectors. I have also tried multiple combinations of Everdrive OS versions and Hi Def NES updates. This project has been shelved since I got the mod because of this issue it’s something I would very much like to solve so I can enjoy the modded console.

 

Any assistance in this regard would be most appreciated

 

Thanks in advance

If I leave Hi-Def NES with Super Mario Bros 3 on the map screen it typically locks up ~15 minutes later if I’m using my Famicom Everdrive N8 with 72pin adapter. Doesn’t happen with an original NES cartridge or original FC cart in the same 72 pin adapter.

 

*shrug*

I just blame the Everdrive. Kevtris has never had much love for it versus the Power Pak anyway. Never locked up on me in use anyway so it’s never bothered me much but perhaps it manifests differently for you. FWIW, I’ve had the exact same behavior in several Hi-Def NES systems with that FC EDN8. I loaned out my NES EDN8 shortly after getting them both in 2016 so I haven’t had it on-hand to test. Dude keeps offering to pay me for it since he doesn’t want to return it. I keep telling him to order one since it was brand new and he’d have to pay me full-price anyway. Guess I should’ve just taken them money and ordered another years ago!

Hi

 

Yes I came to the same conclusion in the end. I ended up getting a Power Pak and this solved the problem i did get it to finally update. It is all working now but was a total pita.

 

Thanks for your insite
