I was curious so I started looking for a 65x version, but couldn't really find anything.

Are there any fast/clever exploits for detecting the intersection of two lines on old hardware?

> It's a matter of perspective. The raising edge of the hsync is arguably the beginning of the next line, in which the VDC generates the interrupt (if line match). After talking with Ryphecha about it, she advised that the interrupt actually triggers near the very end of the previous scanline you a...

> So no plans for b5150 in higan, I take it :p I'm going to have to internally stretch the video (interpolate) from both chips in order to combine them now. The VCE controls the dot clock for both at the same time, not individually. I don't see the problem in mixing the two signals, although VPC re...

Oh okay, yeah. Line coincidence isn't, to me at least, hsync. When I think hsync, I think something like SNES HDMA, where the goal is to fire during the horizontal blanking period of each line so you can write to registers before the next active display section. Huh? Hsync.. when the sync pulse sta...

what I've concluded to e a very unhealthy fixation on macros (almost all responses from him involve macro advocacy). I'd say your lack of consistent work in assembly has gained you an ignorant perception of macros. Anyone who's coded in enough assembly over the years, especially on something like t...

To aliviate the problem, I had a idea to automatically correct the playback cursor over time. The code to do this was really simple, after each copy (ring buffer -> sdl stream), I calculated the difference between the write cursor and the playback cursor (ideally, the playback cursor should be at t...

^ Sure. But if you want to write to vram during active display with Txx instructions, you have to use smaller segments like 32 bytes as not to delay hsync interrupts too long (all writes to vdc regs are buffered, but you have a 455 cpu cycle window to get them written per line). That brings down the...

Pardon me. Let me elaborate the question: 1)the player character is made up of four sprites, unless you're using 8x16 mode. which of the sprites' x/y positions do you use for a base when calculating your collision points? Why would the meta sprite data directly dictate collision data? Make an objec...

In my game engine, I only poll input when I process the player action (or in other cases such as the menu) and do *not* do this in i.e. the VBlank NMI routine systematically. In particular if I do not use the input I do not poll it, however some games polls controller in the NMI routine . ( There i...

The site says "timing-state", so it has both modes right? (I assume it would. I'm a totally new to logic analyzers)

I ended up buying the Owon SDS1702 "used but like new" for $260. Now I'm researching for USB logic analyzer. Something cheap in the 50-100mhz range with at least 8 channels - $100 or less.

I'm also curious about wanting to know if someone could tell the difference between a real NES vs a NES inspired game if the NES inspired game was created with all the NES's limitations in mind. Could you make a game that looks and feels exactly like an NES game, yet doesn't run on real hardware an...

And it looked just as bad there too. How that game runs at only 30fps amazes me.

I take it you're not familiar with that generation?

That AMD chip is an APU; your GPU temp *is* your CPU temp. What more do you want to know???
