Re: Scrolling RPG maps

Yeah the camera can only move in one direction at a time no matter what, so no need to waste time drawing tiles on the back end which will be overwritten if you change direction anyway. The DQ and FF games does seem to draw half of the metatile row on top of screen and the other half on bottom of sc...

Re: Scrolling RPG maps

You shouldn't do the calculations in NMI. You calculate everything outside NMI and only fill a BG buffer with the tile data (including CHR numbers and the nametable start write address) for the tiles that needs to be changed and have a routine in NMI that checks this buffer and only changes the tile...

Re: Scrolling RPG maps

I'm not entirely sure what you are doing. I think you can ignore nametable 2 and 3 as they are just mirrors of nametable 0 and 1 respectively. Anything you draw to the mirrors will appear on 0 and 1 as well, so it doesn't matter which of them the vertical scroll coordinate is at. I guess vertical sc...

Re: RockNES 5.66 -April 9th 2021-

2. You mean like use its mapper emulation to intercept $4016/$4017 access kind of like a Game Genie? Or patch the ROM on the fly? The Everdrive does have mapper 99 listed so maybe it does something hacky with these games. I have no idea if mapper 99 was listed years ago when I tried VS SMB though. ...

Re: RockNES 5.66 -April 9th 2021-

1. No it was definitely the clean Vs Super Mario Bros ROM (though I've tried the patched one as well). The palette was obviously wrong, I just wanted to see if the game was playable on Famicom at all, and it was (if you disregard the psychedelic coloring). 2. You mean like use its mapper emulation t...

Re: RockNES 5.66 -April 9th 2021-

But not on the R&W Famicom I guess? I remember playing VS Super Mario Bros on my Famicom using the Everdrive and it worked fine. It only inserted a coin when I blew into the mic.

Re: SNES oscilloscope readings?

In my experience with Famicom is that people tend to always think it's the CPU that is broken when it's more likely just a dirty cartridge connector or bad AC-adapter. But at least here we have some evidence that the CPU breaks more often than other custom parts. In that picture of broken CPUs it se...

Re: Scrolling RPG maps

Ouch, that means more RAM is needed for attributes. Collision detection should be easy enough in an RPG though, since you don't have pixel-based or acceleration-based movement and basically only passable tiles, non-passable tiles and a few special ones like stairs, shop counters and damage floors. B...

Re: What keyboards do you use for programming?

I agree, I'm not a fan of wireless input devices in general, unless it has motion controls like a Wii Remote or the Switch Joy-Cons where it's necessary to function properly. Batteries causes just too much extra work to keep charged or changed. Besides, wireless controls generally adds to the I/O la...

Re: Help! NESASM Sprite Animation Code Examples

You can't branch to SPSTATE_FRAME1 as that is just the value 1 in my example. If you jump to 1 you would be in RAM, and branching there would give you an error anyway. Also [controller handler] and [sprite drawing code] are two separate routines that works independently of each other. You don't want...

Re: BS-X Satellaview Broadcast Frequency?

Speaking of the BS-X, do you know if it's supposed to work without the 8M mini cartridge? I know it should work without the Satellaview, but I only get a black screen on the BS-X and I have no 8M cartridge yet. It looks like it should work in this video.
