Sprite Splits

I read carefully the operation of the PPU rendering and sprite evaluation, and it seems to me that you could use the sprites to adjust the CHR latch per scanlines (for example, make a sprite $FE and one line down $FD (if after the first one in the OAM) might make a single scanline to use the other bank). Is this correct? --Zzo38 (talk) 11:07, 16 June 2013 (MDT)

Yes, this could work. As you suggest, if you're willing to use sprites from the same pattern table as the background tiles you can do no-CPU-time raster effects. But that's also a big downside. I'm a little skeptical that the inclusion of two switchable banks is particularly useful, given how few pixels all the sprites can cover (using 8x16 sprites, only 14% of the screen). Maybe if you want to clip more than two sprites vertically on the same line, since currently the only solution is overlaying a sprite with another transparent sprite. —Lidnariq (talk) 11:37, 16 June 2013 (MDT)

Circuit to convert MMC2->MMC4 and vice-versa

I just realize the circuits I drew here several years ago are completely useless, apparently Nintendo didn't use such circuit in their cartridges, and nobody else is likely ever going to use them. They serve no "encyclopedic" purpose, it's merely a theoretical possibility that was never put in practice. Is it okay if I remove them ? 128.178.180.88 02:05, 15 April 2014 (MDT) I forgot to log in but it's me, who wrote the paragraph above.Bregalad (talk) 08:14, 15 April 2014 (MDT)
