Re: EPSG for NES and Famicom (expansion sound module)

Connector looks like sawed in half standard 2.54mm edge connector, with just enough spacing to fit the exp connector well enough. Pretty clever ~

Re: Sega Mega Drive Clone - Region Switch Mod

That's a "standard" superclone where all chips are pin compatibles of original Sega chips (made by UMC with better process than Japanese and overclock lot better lol). Jumpers near the encoder chip only control encoder itself and won't affect the region setting or frame rate itself. You ch...

Phase shifts are specified in degrees in all materials I see them in as far as electronics go.

Re: Does everyone still use Winamp for VGM?

I switched to XMplay years ago and never looked back at Winamp again. All the Winamp plugins I used previously work properly in it too, in addition to native plugins of which there are plenty of too ~

Re: The 16-bit War. . . .

Looks like 90+ games use PSG channels. Out of 700 total is about 13% of games. And the list I saw frequently said only some times ... let's say half of the time. We could make a rough estimate and say about 6-7% of Genesis songs used PSG. It seems the most popular reason is for the noise channel......

Re: So, regarding the sprites per scanline . . .

* SNES only has time to parse 128 sprites on one line, there's no memory bandwidth or memory itself to have more, this sets the maximum sprite count possible, ignoring the other limits : ** Pick out 32 sprites it deems visible on that line (regardless of size) and store their parameters in a list fo...

Re: Sega Mega Drive Clone - Region Switch Mod

With luck, SW4 in top right corner connects to the JP/EN pin, in some machines that is where region setting switches are exposed.

J3 is video output 50/60Hz setting J1 is Region register PAL/NTSC setting (has nothing to do with video output) Japan/Export is unavailable, but it is done by PCS8492 pin 72 (GND=Japan, VCC=Export). VDP (PCS8391) seems to be a bit modified compared to normal superclone VDP, it seems to take a crysta...

Sync timing and periods are critical for all display devices, there isn't much playroom with them.

Re: Why does having a bigger tilemap matter?

You'll probably quickly discover that having only 3 colors per tile in all the BG layers gets very limiting in mode 0 artistically, there aren't many palettes to use either to get more out each BG layer. Good for making "NES on steroids" kind of visuals, but getting into "16bit" ...

Re: Wrong post count for user

I'm no fan of xenforo either, every forum I visit that has "upgraded" to it has come with many negatives on even the most basic functionality. Much more clunky, with a big RAM footprint and seem to be really CPU heavy making it really sluggish. I can feel the laptop get hot when it is open...

Re: Regarding SNES' object limitations

As far as the multiplexing goes, I perfer to use the recycling instead, I find it more descriptive of the actual process that is generally meant by it. Reusing a sprite that has been rendered by moving it to a new place on the current frame, to get something show up in the new spot.

Re: Black borders to left and right of SNES game footage

Those are border inside the video signal itself, one video line is ~64µs long and only ~52µs of it is not blanked, and a console outputs active image only in part of that 52µs and most TVs do not show all of that 52µs either (overscan etc.). The MD has this sort of border too (as do pretty much all ...
