Re: Dragon Ball - Shen Long no Nazo English Translation

To be fair, damage on the cartridge board that causes CIRAM to not be able to use the correct mirroring, and instead restrict it to Single Screen mode is still "wrong mirroring". :P

Re: Latency challenge of conventional emulation compared to FPGA

I didn't really see any point in the first post where Input to Output latency was mentioned at all, but that's what the topic ended up getting changed to... When you have RunAhead 1, and Exclusive Fullscreen mode, you've matched console latency for a local keyboard, then RunAhead 2 (if the game actu...

Re: Super mario bros 2 (USA) level format.

Try a romhacking forum first, or go download a level editor, and see what happens when you move the blocks around.

Re: Custom Emulator for Steam release of Homebrew

Shouldn't really be allocating a new texture every frame, instead you should update the texture.

Re: Starting a YouTube channel: where should I start?

The point of the Chroma Subsampling post is that you cannot upload at 240p. You must be 480p or greater.

Re: Starting a YouTube channel: where should I start?

[*]YouTube has a limit of 30 frames per second for videos that are smaller than 720p. As far as I'm aware, all videos of the output of an NES PPU are smaller than 720p, as the PPU produces only 240 lines of picture. This limit would provide a misleading impression of tech demos that I have produced...

Only Edmund McMillen could get away with that. He was doing it for 10 years ("Dead Baby Dressup" on Newgrounds) before Binding of Isaac released.

Re: Looks like NESCartDB is down (again)...

"Super Mario Bros." has no PCB scan. https://nescartdb.com/profile/view/270 And when I said "Alternate profile", I actually meant "different dump". That's when you have the same game, a different picture of the PCB, different manufacturers for the chips, may or may not be a different revision. These...

Re: Looks like NESCartDB is down (again)...

I see that some things are missing from the mirror, such as alternate entries for games, and lots of PCB scans.

Re: 8-Way Scrolling Screen Compression Method?

Times of Lore and Ultima V have HUGE overworlds for the NES. 512x512 16x16 tiles large. And they are very repetitive too, you can see the patterns clearly, as they are made up of big meta-meta tiles.

Times of Lore overworld map
Ultima V overworld map.

Re: 8-Way Scrolling Screen Compression Method?

This is where a background in ROM hacking would help, you'd be familar with the ways of encoding map data. Many Nintendo games use screens made up of objects placed at locations, at various sizes, such as Super Mario 1, 2, 3, Metroid, Kid Icarus, etc... The Dragon Warrior series uses RLE compressed ...

Re: Is there a logic to instruction timings?

Each time the 6502 needs to get something from memory, that's 1 additional cycle. And there's a minimum of 2 cycles for some reason, so the first 2 bytes of the instruction are already available. Examples TAX, TXA, ASL A, etc. are all 2 cycles because they don't need any additional memory access LDA...

Re: How to limit 60 FPS in a loop?

Happy case: 60FPS refresh rate, 60FPS gameplay speed. You use Present (from Direct3D/DXGI) to update the screen. It enqueues a screen update, and waits for vsync (with no unnecessary CPU usage) if there is already an update pending. Less happy case: Something that's not 60FPS as the refresh rate. Us...
