Re: White screen on new opentendo build, no signal on M2
Many thanks for the quick reply. Just to check, taking it to ground would be sufficient, for a couple of seconds? Or something more advanced needed to replicate the original reset switch? About 1/10th of a second. Maybe less? Don't need more (but more is also safe). Looking at the schematics and tr...

Re: VS. Excitebike Mapper Hack?
Seems like a great time to learn how to use an emulator with a debugger, then :p

Re: Video Game Consoles with games stored in single-sided cards
For it to be two-sided, I imagine it would need to be much thinner than a normal cartridge, since the card-edge is in the back part of the shell. ... ok, now I'm thinking about the feasibility of stuffing 4 games in one card. What about Fairchild Channel F? It looks like it's single-sided with 22 p...

Re: White screen on new opentendo build, no signal on M2
Following another thread around a similar sounding problem, I looked at testing M2 and A0, and I have nothing on either pin. I'm having to make do with a 24MHz logic analyser, and if I try this on the CPU-CLK pin I at least get a measurement, but its 2.6MHz - suspiciously out by 10x but I suspect b...

Re: Converting PAL to NTSC using Famicom
The majority of US NESes have revision G or H PPUs, and they have a specific bug that some games rely on.

Re: Video Game Consoles with games stored in single-sided cards
Oh, huh. I was incorrectly under the impression that those were SD cards mechanically.

Re: problemkaputt.de is gone
Oh, and somebody has PMed a sample github page. I does support http (unlike the usual inaccessible https-only github pages), and ftp seems to work too (at least it's showing a login prompt, and doesn't seem to require the defunct github user interface). Not so bad. I am not sure if it does support ...

Re: Animated Optical Illusions
The only thing is, on the NES you don't have any layers other than the sprite layer. So the animation could only be as big as a square grouping of all of the sprites. The sprites themselves are the black bars and are 7 pixels thick with 1 pixel being transparent. Have the zoetrope mask move vertica...

Higan manifests already support this, no need for recompilation.

Re: Witch n' Wiz - Puzzle Platformer
I believe you have a budget of 64KB total (after any CHR compression). Obviously, consult with someone who's actually in charge instead of going on my memory.

Re: Using high bank lines as address decoder?
What nocash said. To wit, software can prevent a bus conflict if it there's another place it can access the same memory. But by using A22 (BA6), there's no way to access only SNES-internal RAM (any place where A23 downto A17 = 7'b0111111 ) without also accessing your hypothetical decoded RAM (any pl...

Re: NES-001 cap replacement guide for the av power module
Obviously the RF modulator itself differs - it has to modulate audio and video to different frequencies for PAL vs NTSC. But the RF switch should be pretty similar.
