Hey guys,
I just wanted to share the outcome of my latest project: NES2JAMMA
First let me tell you that I'm not a big fan of putting game consoles in arcade cabinets. But playing NES games in front of an arcade cabinet is not that weird because of Playchoice 10 systems.
I know there are similar projects (not so many though) floating around the internet but never had a clear schematics or detailed info regarding how it works etc. So I decided to share the information so that anybody willing to do it could save time on reading lots of datasheets and choosing the right IC. I do not say that it is the perfect design (I'm sure many improvements can be made) but the outcome is quite satisfactory and playing an NES with arcade controls infront of an arcade cabinet is fun
Here is the schematics of the circuit I came up to amplify the video and audio... I used TLS1233 and LM1881 for the video amplification part, a basic LM384 for the audio amplification part and CD4021 shift registers as arcade controls encoder for NES.
And this is the PCB I've made based on the above schematic.
For this to work you need an NES console which can output RGB video. Alternatives are:
1) French NES: French NES consoles output RGB over SCART. It is actually the Composite Video decoded and separated into its R G B components not a PPU generated native RGB but quality is OK.
2) RGB Modded NES: You have two options here. You can either mod your NES with a PC10 PPU or mod it with a NESRGB kit (which I did) without sacrificing an arcade system.
I've tested both (French NES, NESRGB modded NTSC NES) and am quite happy with the results...

You can also play VS games on this system. Thanks to Krikzz Everdrive N8
