Re: Buggy background rendering
How does your renderer handle the CPU writing to the PPU outside of vblank? The litewall ROMs do a whole lot of timed mid-screen PPU writes to get those effects.

Re: NESRGB Blue Scrambled screen
Aha, that explains it. Your multi-out-to-SCART cable is upside-down.

Re: NESRGB Blue Scrambled screen
I would guess either your TV isn't compatible or you've mixed up the output signal wires somewhere.
How exactly did you connect the NESRGB to your TV? It looks like you have some kind of connector board in there, but I don't recognize it from any other NESRGB installs I've seen.

Re: AUX on the Yobo Gameware FC2
as soon as I find a male/male cable, I'll try it. I hope you're thinking of a USB-A to USB-C cable or something along those lines. A male USB-A to male USB-A cable will probably damage something. I'd just open it up and see how that port is wired up inside the console. Power output that only works ...

Re: Weird 15 in 1 Cartridge
The address and data pins are in the wrong order. I was able to rearrange 15C.BIN to get something that looks like the correct CHR, but it doesn't match the board layout or krzysiobal's schematic, so I'm not sure what's going on...

Re: Trying to write a C# nsf player, 95% there but stuck.
1. What's the recommended way to control the playback speed? Playback speed is controlled by how often your NSF player tells the emulated 2A03 to execute the play routine. Typically that's handled by cycle counting inside the emulator, which indirectly ties playback speed to the audio sample rate (...

Re: Linux on NES
The same is likely true for the 8086, but I'm not as familiar with UNIX stuff on the 16-bit x86s, I imagine they'd also pair it with an MMU, although it's using segmented memory natively iirc (cs, ds, ss, and so on.) There were a handful of 8086-based computers that used a MMU to provide virtual me...

Re: N64 16Kbit Eeprom saves and padding. (Solved)
Have you tried creating a new save on your Everdrive to compare against a save copied from your cartridge? Maybe the data needs to be rearranged for the Everdrive.

Re: What happened with Miracle Piano rev-engineering?
Huh, I posted about which MIDI messages the piano can receive, but not which messages it can send. Here's all the MIDI messages the Miracle Piano can send: 9x xx xx bx 40 xx bx 7b 00 cx xx f0 00 00 42 01 01 0x f7 f0 00 00 42 01 03 0x f7 f0 00 00 42 01 05 xx xx f7 f0 00 00 42 01 0b 0x f7 The piano ma...

Re: What happened with Miracle Piano rev-engineering?
Most of the digital logic inside the Miracle Piano is contained within two ASICs, labeled AS0012 and AS0013 in the schematics but 800502 and 800601 on the actual chips. The AS0012/800502 ASIC provides the keyboard interface, the game console interface, and the PWM volume control signal. It's connect...

Each byte, one by one.
I've used this program for things like that, but I'm sure there are lots of ways you could do it.

Re: What happened with Miracle Piano rev-engineering?
Could be! I haven't looked at the games at all, but the MIDI messages I listed are the only ones the piano understands. At least two versions of the Miracle Piano main board exist. The (presumably) older version, marked "800951 REV B1" in silkscreen and copper, seems to match the schematic...

Re: s29gl064n90tfi06 don't wortk
My question is if there is any difference between these models S29GL064N90TFI04 has byte mode, activated by connecting the BYTE pin to ground. S29GL064N90TFI06 does not have byte mode. To use the 06 in place of the 04, you need to repeat each byte when you program it, which means it can only hold h...
