Here's an update! So I bought a standard white/red Famicom with no mods over on Famicom World. I initially couldn't get it to work, but I had a second CRT lying around and was able to boot it up using channel 95. This Famicom worked perfectly with my original FDS RAM adapter. I haven't tried out the...

Yeah, my Famicom is modified to use component cables - it's one of the mods that appears professional (there are cable ports on the side of the system rather than sticking out of the controller wiring, for example). I've historically had a very difficult time getting Famicoms to work with an RF swit...

OK! It's time for a new chapter in Zycrow's Weird FDS Problems. Today I received in the mail another package from the endlessly generous Koitsu, and this time it was a third RAM adapter (we will call it subject "C"). The bad news is that subject C did not solve our problems. In fact, to ma...

OK! I tried a couple other things, but the results weren't terribly surprising. First, I used my FDS and RAM adapter and powered it on with Koitsu's AC adapter. The results were garbling, as usual. I then used this same configuration switching to Koitsu's RAM adapter, and the garbling was gone. I al...

Please try the power-related tests (AC adapter vs. C batteries). There's something that just doesn't sit well with me about this situation in general -- it's probably the OCD part of me wanting an actual explanation for what is going on, rather than just swapping FDS RAM adapters and saying all is ...

My suggestion is, if you have any of the games on this list (which contains all Famicom carts with CHR RAM) is to test one of those games and see if you also have corruption. The only thing to throw a wrench into that line of reasoning is that your FC worked with koitsu's RAM adapter but not your o...

OK, you guys ready for some weirdness? I got Koitsu's hardware in the mail yesterday and this morning I did some tests. Here are the results: - My FDS with my RAM adapter (again): Garbling - Koitsu's RAM adapter with my FDS: No garbling (tried all games) - Koitsu's RAM adapter with his FDS: No garbl...

I haven't received Koitsu's FDS yet, but when I do, I'll post a report of what configurations I try and how it all looks.

It is the same sprites every time, yes.

Well, that answers some of our questions!

To answer yours, I have been powering my FDS with batteries. I believe I have an AC Adaptor that would be usable, based on Famicom World's guide, but I haven't tried it as of yet.

Cool! I'll send you a PM and I'll update the thread if more is figured out on this issue. Again, I appreciate everyone's help.

Well, at the very least I'm learning some things about how the FDS ticks! :D Seriously though, thanks for everyone's input so far. Buh. I have really no idea what could be causing this ... it's definitely not simply the adapter's CHR RAM, if that's even to blame at all. I don't suppose you might hav...

The problem could be with your RAM adapter. The BIOS doesn't use all of the Character RAM. Maybe there is a problem with an address line on the chip. It could be that a solder joint went bad or the chip somehow is damaged or not working now. I would try another RAM adapter if that is a reasonable o...

Unfortunately, without the ability to run arbitrary code on it, I have no idea how to go about debugging which of these things could be wrong. I can't really tell what's going wrong from the picture on your thread at FW... could you provide a picture of Mario (or anything else corrupted) against a ...

Hello - I'm not sure if this is the correct part of this forum to post this question, but here we go. A few weeks back I got a Famicom Disk System. It works almost perfectly, but - in some games worse than others - the sprites have garbled, glitchy areas. It's worst in Mario 2, where half of Mario/L...
