Pseudo-HiRes works in modes 0-4.
Mode 7 too, probably.

Re: PEA/PER/PEI instruction and stack relative addressing modes

The right edge also moves. Naively, I would have expected the horizontal blanking period to be slightly shorter to account for this difference; instead the active portion of scanline #141 is one high-res pixel shorter. I have to assume that the IRQ is in the middle of the display. Thanks for testin...

Re: PEA/PER/PEI instruction and stack relative addressing modes

These should be the registers to set: RESET: ; write %00000000 to $212C (TM ) to disable backgrounds & sprites ; write %00000000 to $2121 (CGADD ) ; write %11111111 to $2121 (CGDATA ) ; write %11111111 to $2121 (CGDATA ) to make color 0 (the entire screen) white ; write %10001111 to $2100 (INIDISP )...

Re: PEA/PER/PEI instruction and stack relative addressing modes

what do the "Main Screen" and "Sub-Screen" on the SNES actually mean? You could read anomie's docs or watch this channel for that. In short, the SNES has a horizontal resolution of 512 pixels, it's just outputting the same color for every pixel pair (called "dot") in most cases, exceptions being th...

I don't really get the point
6502 was designed to do as much as possible with a very limited transistor count. As a result it sometimes appears inefficient or confusing.

Re: Non-MSU video player

24fps is not evenly dividing 60fps, so you will run into the 5kb vblank limit per frame. 24fps -> you'll sometimes have two and sometimes three frames to upload the next one. frames 0-1: upload frame A frame 2: upload end of frame A, and beginning of frame B. frames 3-4: upload rest of frame B. If ...

the right-most column is blackened with sprites to hide the tiles that are scrolling in, like its done in some NES games
Are you planning to use the window registers for something? If not you could use them to clip the screen, to eliminate the possibility of sprite flickering in the future.

Re: Nova the Squirrel 2 (WIP)

Making it not aligned to the grid seems like it has promise Add support for the mouse and it might feel like a modern 3D game :P I don't think making it feel more like Blue Sphere aesthetically is important, unless you think the curve helps to make it easier on the eyes? I don't think it's possible...
