Below are links to the NES fpga: 1) https://github.com/brianbennett/fpga_nes Using Spartan 6 : Nexys 3 There is a glitch in one game that was discussed here: http://forum.gadgetfactory.net/index.ph ... pistrello/ 2) https://sites.google.com/site/ece31289u ... oratorio-3 Using Cyclone IV : DE0-Nano Uses the same source codes in (1) but no glitch. Works nicely. 3) https://github.com/strigeus/fpganes (Luddes NES Blog) Using Spartan 6 : Nexys 3 or 4? Requires USB joystick on PC. Customized software to load games and joystick positions to FPGA. I could not get either to work on Nexys 3. Appreciate if anyone can help investigate the glitch in (1) ? |

Is this the glitch in question? Quote: One thing I did notice is that some of the sprites have a vertical line of missing pixels but over all it looks pretty good.

Yes, that's the glitch. No glitch on the De0_Nano version. |
