Re: State of GB repro boards

We finally have a good solution. RetroStage released a properly made MBC5 board on Jan 17.

4 or 8 mb ROM, 32kb batteryless FRAM saves, 18.50 for the lower size.

Only the best emulators include a "blow on the cart" option.

Re: Load sprites from differents chr banks

With MMC3, you have 2kb banks for one half (bg or sprites) and 1kb banks for the other. So you can have BG from two or four parts, and sprites from two or four.

Re: Graphical glitches on the Everdrive

The PPU bug it tests for is the color readback, it uses that for save states.

Re: untitled platform maze game

Just based on pics, your games all look the same. Maybe try a different direction for a change?

Re: Zap Ruder: The Zapper test ROM project

I tested this with the Hyperkin zapper and a LCD. As expected, pretty much only the "how long did you hold the trigger" test worked. In addition to the lag, seems the expectations on what is considered light change. Y-pos detection is fairly useless anyway when your TV has a lag of 5-10 frames. edit...

Re: Setting up a 24-bit pointer

That is the way. If you don't want to see the extra write you could wrap it in a macro.

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...
