This is an FPGA implementation of the NES/Famicom based on FPGANES by Ludvig Strigeus and ported to MiSTer.

Jun 12, 2011 · Unfortunatelly "SMB 2 players" is based on VRC6 mapper, so I would need to make FPGA emulation of it, but that would be waste of resources because game utilizes only tine subset of mapper's capabilities.

Nov 7, 2018 · MiSTer's NES core is getting Nintendo Famicom Disk System (FDS) support care of GreyRogue, making it the first FPGA system that natively supports FDS without needing additional hardware to load ROMs. The same update also adds expansion audio for VRC6 and Sunsoft-5B mapper games (Gimmick, Akumajou Dr

Jul 18, 2022 · The Konami's VRC6 ASIC mapper comes in two variants: VRC6a - iNES Mapper 024 used for Akumajou Densetsu (Konami PCB 351951). VRC6b - iNES Mapper 026 used for Madara and Esper Dream 2 (Konami PCB 351949A). The difference between the two variants switches the A0 and A1 lines.

Nov 23, 2014 · I want a NES PCB with a small FPGA chip on it that can eliminate sprite flicker just like how the Analogue FPGA console can do. I also want this FPGA to be able to recreate all of the extra sound chips like VRC6 and such.

Apr 15, 2010 · Playback of VRC6 or VRC7 expanded NES music (original composition) on real NES hardware? I have a feeling someone must have, but I'm curious what it would entail. EG, getting the NSFs to play on a VRC6 cartridge, getting the audio mixed properly, etc.

Sep 15, 2015 · I recently finished a project on my NESRGB-modded console, where I wanted the Everdrive N8's VRC6 audio mixed in with the NESRGB's sound output. In this case, I found you don't bridge pin 9 with pin 3 with a resistor at all.

vrc6的irq是基于cpu而不是ppu, 所以水平同步接口增加了一个参数(扫描行) 两个变种区别在于地址线A0, A1反了 VRC6扩展声道加起来是一个6bit数据, 但是会除以大约128.

Apr 4, 2023 · Nested MSU-1 hacks that are patched to be compatible and run on the MiSTer FPGA SNES core. The MiSTer FPGA SNES core only has 128K of SRAM so only certain Nested MSU-1 hacks will run, and only ones that use a simple mapper.

May 12, 2021 · Pictures of VRC6b to VRC6a conversion. Bonus points for guessing which game before checking the pics. - VRC6 chip desoldered and pin 9 and 10 lifted and swapped with wire. - 27C020 EPROMs for PRG and CHR (x2) - pinout was conveniently compatible. - New 100uF 16v electrolytic capacitor to replace existing 100uF 6.3v cap.
