Re: UMC UA6528 = Ricoh 2C02E, not G?

Oh, no. I intended to design my own NESRGB/HDNES thing but only got as far as socketing the PPU. OMG please do, let's make it open source! It could support VTxx color tables too! I would help any way I can. A prime example is the open source RGB adapter for N64 from borti4938: https://github.com/bo...

Re: Kaiser chips KS204/KS203/KS202 + kaiser boards

oh i forgot to mention my favorite part of that Devil Town II cartridge. the CHR-RAM socket. there's a 6264 already surface mounted there, which means the socket was installed afterwards . WHY?? so if the original SOIC fails, you can instantly piggyback a new working DIP part? how... thoughtful??? ...

Re: Consequences of trying to disable CIRAM in clones that don't allow it?

I am really impressed by what you have done here within so many constraints. It is so easy nowadays to say, put in an FPGA and 1 GB flash into the cart, rasterized graphics, etc, and that's tempting and interesting but frankly not authentic anymore once you do that. Something of the original charm i...

Re: Consequences of trying to disable CIRAM in clones that don't allow it?

That alternating rows wouldn't even be possible on a NES, I think. It is possible the way I'm coding the rendering engine. Each pair of software pixels is a separate tile, and I use raster effects to display only 2 scanlines of each row of tiles. If I update odd and even rows of tiles alternatingly...

Re: Rainbow : a WiFi cart / mapper for the NES !

Can I ask what level shifter chips you're using? Is there just 2 or do you have more on the back of the board? Any issues with them (data direction, latency, etc.)?

We are better than professionals, because it's personal and we actually care about it. We get to own what we do here. :wink:

But then at the same time, none of us are obligated to continue when things get hairy so maybe we're not so professional... :?

Re: Help with NES-001 Power and Modulator PCB

Recently there's been two or three "made from scratch" NES motherboard schematics. They expect the original CPU and PPU (or compatible clones) but use new components otherwise; maybe setting up one of those would be easier for you than reversing the old power board? It sounds like megasdkirby's mot...

Re: NESRGB failed install

Are you sure that isn't just normal? NES is notorious for bad connection to cartridge. Maybe it needs more blowing in it or wiggling.

Re: Fixing Chinese SMB2J

I just wanted to follow up on this, FINALLY I got around to completing this modification to my SMB2j cart. I reflashed the ROMs to loopy's original version and I found that it did not work with my real Famicom when I changed the cap to 4.7nF per aquasnake. I changed back to the 56pF in the original ...

Re: Late 1980s / Early 1990s Memphis Style in NES Games

I would say it has some influence, what game is that?

Edit: I see it is Chu Chu Rocket.

Re: Late 1980s / Early 1990s Memphis Style in NES Games

You're right, I was way off, though your box art does show it. Sonic might have a few things here and there in-game like SMB3 but not much.

Re: Late 1980s / Early 1990s Memphis Style in NES Games

The more I think about it, Toejam and Earl is the one that nailed this style. I think Sonic is pulling more from some other 80s/90s style, but I am not sure what that would be or if that has a name. Sonic is doing something a lot more industrial and I think that's why FM synth works so well for Soni...

Yes very good points and I agree that M.C. Kids does use that style.

Re: Late 1980s / Early 1990s Memphis Style in NES Games

I realize now that Klax is an NES game in this style, at least the box/label art. Can you think of any others?
