Re: anyone making a fpga snes with hdmi?

The Analogue NT mini can't do HDMI and analog video at the same time.

Re: Diode bridge burned in a French NES frontloader ?

I thought all French NES were RGB out.

Re: NESRGB on Toploader w/ Expansion Audio using NESRGB Audi

Remember to keep the resistor lead/wire going to the rgb-board as short as possible (I wired the resistor directly to the board) to keep the noise at a minimum.

HiDefNES doesn't do 1200p though.

Re: Hi-Def NES HDMI Adapter for the NES

@kevtris Did you try Legend of Link on a repro ora flash cart? Powerpaks and Everdrives has too little CHR and PRG "ROM" to run that game correctly.

Could be nice to have composite, to show people how massive of a difference this kit makes. :)

Re: Hi-Def NES HDMI Adapter for the NES

+1
Amazing work Kevin, I never doubted it would be anything else but great.

Maybe, if possible, you could put double solder pads and through holes so that the HDMI-connector could be mounted in two different places and "the flag" could be cut or sawed off.

Maybe something like this, repeating?

I came up with this myself, aften exper...

Re: Hi-Def NES HDMI Adapter for the NES

Micro Machines works fine as far as I know. Kevtris showed it working in a previous demonstration video. The only trouble was a small black line where there shouldn't be one. This was quite a while ago so maybe he has already fixed it? He also showed some other games and demos working correctly that...

Re: SMB1 + SMB2J SRAM Plus (FDS hack)

Exactly what do you mean by SRAM? Ability to save your progress? When I think of SRAM I think of cartridges, not FDS floppies. :)

What I'm asking is: Does this run on real hardware?

Re: mario in some usual day

Internally shorted batteries would be protected from the power supply rails by the diode. That said, you're right, I forgot there's the current-limiting resistor there. True, I never thought of that. That diode does lots of things. Protecting the battery from the console's higher voltage, relieves ...

Re: mario in some usual day

Two problems ... one, that shorts out the battery (no good for the battery) through a diode (no good for the diode). two, there's no guarantee that the power-up pattern in RAM is all 0s. But I don't have a better idea. I don't think I've seen a cart without some kind of current limiting resistor. B...

One way to do it is to open the cartridge up and use a small cable to make a short between Vdd and Vss for a few seconds on the SRAM chip that hold the save data. You will need to know the pinout of that chip though.

Re: FDS Writing extension for TapeDump

I just want to thank Chris for this excellent piece of software. It saved my copy of Legend of Zelda (by rewriting it) that had gone corrupt somehow. Sure, KCS wasn't the easiest thing in the world to get working but in my case it was worth the trouble. Saving games from the trash can is saving hist...
