Got my Jammaizer prototype in the post today and put it through some rigorous testing / game playing tonight. It's friggin' awesome, and this is just the early version, I'm really looking forward to the new / final revision: Respect to
@Arthrimus who really outdid himself with this, it comes with my highest recommendation.
The quality is top notch, the matte black looks great and everything works a treat. I got two of the MC Cthulhu boards which plug and play just fine, I recommend this route if you haven't got adapters already as they not only look the part, they just work. I've had issues with other controller adapters, but this one hasn't thrown me any major problems... it autoswitches to the consoles I tested automatically. Actually, the only issue I ran into is that God Hand wouldn't accept any input, a controller plugged into the PS2 worked fine, I'm assuming that game has forced analog?
I didn't need to adjust the RGB pots at all from what they were set at. The audio can get pretty loud out of the console / RGB cables, so I kept it low and cranked up the volume in my cab.
Everything tested on an New Astro City with a Nanao MS9 monitor with RGC Scart cables, CPS-2 Kick Harness, Saturn with a Rhea, PS1 with a PS-IO and PS2 with FreeMcBoot/OPL and a HDD Adapter. There's practically no load on the PSU whatsoever. I came in at about 5.18v when I first plugged it in and adjusted it down, for reference my PSU is set to be at 5.1 with a Cave CV-1000 PCB plugged in.
I guess I'll let the photos do the rest of the talking, this is a majority of the games I played through thus far. I'll run some other consoles through it over the weekend and test it out on some other monitors / the Sentinel Supergun, but I honestly don't for see any issues. Hats off again to Arthrimus for this!
