Do colored borders bother you?
I'm the lead programmer for an NES game in development, and the fact that the side borders are not black bothers the person to whom I report. The borders stand out about as much as the blue side borders in the title screen of Nintendo's Super Mario Bros. 2 (pictured). smb2title.jpg How many other pe...

Re: Need guidance with nes to snes.
You can DMA from ROM to VRAM, from WRAM to VRAM, or from ROM to WRAM with a fixed source address.

Re: Pong de las Tortugas Ninja Trilogy
Last I read, ViacomCBS's terms and up-front fees weren't friendly to amateur or small-time professional licensees. I don't remember where I read it, but I vaguely remember 40,000 USD just to open negotiations.

Re: question about systems that support PAL60 systems
PAL-M is 480 of 525 lines and 60 Hz, as anyone familiar with the history of analogue video in Brazil would be aware. The difference between PAL60 and PAL-M is that PAL-M is a standard using a chroma subcarrier frequency close to NTSC's 3.58 MHz, whereas PAL60 is a nonstandard format using the same 4...

Re: Need guidance with nes to snes.
On Super NES, setting brightness to negative turns rendering off (also called "forced blanking"). I'm not sure I understand what you mean.

Re: Need guidance with nes to snes.
The equivalent to turning everything off is writing a negative value ($80-$FF) to brightness ($2100).
