Re: Reverse en + dump of pocket VT-xx based handheld famiclone (Karaoto Video Juego Interactivo)

So did this unknown author actually demake Crash, Mario Kart, and Angry Birds, or are they just hacks of something?

Re: Curious about MMC5 5209/520A registers

The vertical split is not that useful though, because it's tile granularity, not pixel. Meaning you can't do proper sliding transitions with it (well, you could hack the pixel position with sprites, but PITA). Leaves only vertical shooter HUD pretty much as the use case.

Re: What is MMC5 "3-screen mirroring" good for? Answered inside.

Sorry, my bug. During testing had moved the first 5105 write around, which directed the NTA/B writes to a wrong area. After fixing that, fceux displays a proper picture (mednafen is still broken).

Re: What is MMC5 "3-screen mirroring" good for? Answered inside.

The A and B nametables contain a grass/forest scene in green and white respectively (bad programmer art, but just for testing). So everything below the HUD should have NT A contents since there isn't yet scrolling, and at that point the IRQ triggers the 5105 write from "exram nt only" to "vertical m...

Re: Making sense of GBA RGB555 output signals

There are already a couple "GBA on a SNES" solutions, they all have their own video output and just use SNES for the controller and power.

Re: What is MMC5 "3-screen mirroring" good for? Answered inside.

Apparently emulators have trouble with writing to 5105 while rendering is on. Trying to do exactly this, both fceux and mednafen display a differently broken image. I'm not on latest git versions though, maybe those are better. edit: Nintendulator too. Bankswitches take effect, but the 5105 write do...

Re: Issue with NESRGB sync on PAL console: Composite Sync vs CSYNC vs SYNC on LUMA

Bah, of course. Typical Nintendo to use non-compatible things just because. Sorry, I thought from quick googling it was the standard multi-out.

Also, high quality male to male scart cables are easy to find, whereas no good quality cables are available for the French NES.
Retro-access? You may have to look under the SNES section for a multi-out one.

Re: NES zapper + LCD

MegaCat sent me one for future dev, but I don't have a setup to test it currently. The gun has a three-step lighting level switch for different rooms and TVs, and the manual says the Duck Hunt patch works like the lcdmod patches, aka you manually tune the delay on the title and pause screens. I was ...

Nano. I require the editor to start in less than 100ms, and stay out of my way.
