Yup, that is right - the color is changed without respect to the VBLANK. I was quite curious why this happened, I am not master at CPU-PPU interaction in NES. But i did not want to wait for VLANK because that could slighty prolonged the programming time.tokumaru wrote:Looks cool! One minor nitpick I have is that the loading screen looks glitchy because of that white line that shows up whenever the color changes, which I'm guessing is there because the palette is changed mid-frame. Would it be possible to code that part so that the color change happens during vblank?
I was also considering adding some kind of progress bar - that could be possible when programing PRG-ROM, but impossible when writing CHR-RAM (unless i would program it only in VBLANK which would take 100 times longer).

Yea, the product is available for sale - the price, including delievery in Poland is 330 PLN (around 85 USD). The price includes the cartridge PCB, cartridge shell, 4 GB Micro SD card and USB-MicroSD reader for putting roms into card.Anyway, is this gonna be a product available to the general public? If so, how much will it cost?
The price will probably be the same for the whole Europe, but overseas delievery might be quite more expensive. Also, which I did not mention, the cartridge has possibility of firmware update - just puttin newer version on SD card and chosing it in console like ordinary rom file.
More mapper support is not planned, as I was intendent to concentrate only on most popular mappers. Also, the choosen FPGA chip is 95% used.
