It took me about 2 years to get some very niche stuff over the line after quite a few ETAs that came and went.
Best advice I can give anyone is that until it's shipped.... any ETA has to be assumed to be an ever evolving thing.
i think it's twofold. they don't want to spend the cash making a new board, sourcing new chips etc as it all costs money
BUT if they did do it I wouldn't surprised if everyone who's ever bought a 161 cart would also buy their full set cart.
they just don't see the investment as worthwhile...
When i realised that the AC Mini stick was more or less just a copy of the VSHG a couple of years back, I messaged Alberto about getting 2 panels made so I can have a black and white pair of sticks for my Neo Geo.
It was a drawn out journey and I've since had these panels for about 9 months...
I bought a few of these a while back as some shells for carts I've picked up have been wrecked over time and tbh, they're decent. Esp for the <£10 or so they're going for now.
as soon as I saw the price of 5 I was keen to see how real it was and I was utterly disappointed to find out it was actually a boot and not just a really, really good price. it's one of the 5 MVS carts I've still to get for a full set as well.
I got my NAC in and upstairs no issue after I'd taken the control panel off it and the monitor was out. Depending where you're getting it from you may want to open it up and give it a real good clean down anyway. There's usually about 25-30 years worth of Japanese arcade grime and smoke inside...
my Shock Troopers cart was absolutely pristine when I got it but there were some weird gfx glitches.
Went all over the boards and everything looked alright apart from 1 trace that didnt' look corroded or anything but it just wasn't quite as good as all the others. checked continuity and it was...
true dat! I don't play it any other way than on my DC with twin sticks. Interestingly, I was talking to the Bitmap Bureau guys at an expo last year and they had some modded Megadrive/Genesis controllers from some Japanese modder, which has enabled twin sticks. Instantly made it more playable.
Personally, I'd go the route of the new chassis. You could pick up another crt without too much of a bother but a spare MS29 is a lot harder to come by.
I had thought it might have been part of the ArcadeOffset set but seems it's only FreePlay or Training hacks that exist for it. https://github.com/atrac17/Arcade_Offset
