I bought one a couple of weeks ago; it's almost here. I'll post up some pics and thoughts when I get it

I bought some spare *untouched* A boards off a seller on Taobao. No issues with those and a good value at less than $50 each. They were also extremely clean.

Everything else with hacked up audio and those cheap red replacement dipswitches is total fucking garbage. Usually filthy as sin/yaton as well.

My suggestion - stay far away from all the Chinese ebay shit. Serves a higher function as landfill.

The toaboa people are selling more or less the same thing as the ebay vermin but you can also just get a motherboard and it won't be all muddy with hacks. Tbfocus is you are interested.

Anyone with experience with the legendHK converts? Man, the market has gone to crap; ebay only has bootlegs or super overpriced 'collector grade' boards for 5X the price of what's socially acceptable. I regret not buying more boards back in the days, but I didn't want to be like those pcb hoarders who buy tons of pcbs but never play with them. Ugh.

Sorry for the random rant. If anyone has interest with those legendHK convert jobs, i'm all ears! Are there audio problems?
I have a legendHK daimakaimura conversion.

The Sound failed after about 30 minutes of use.

The A board appeared to be stock.

He sent me a replacement A board and it's been working fine for about a year now *knock on wood*.

Pictures inbound. Got my Forgotten Worlds from ebay seller "LegendHK" Based on the generic auction pics, I was hopeful that this wasn't a total hack job.

First, the packaging was encouraging. Bubble wrap around box, PCB inside box also bubble-wrapped:

Note the business card; at least they have contact info. Interesting they took the time to include a xerox of the manual:

Here we are; i'll give them credit for nice EPROM stickers that look legit.

Arg, the pics in the auction show a regular audio section. This one is the crazy hackjob amp replacement version with that Diode attached we've seen in other examples from @Kujako. If I ever think my soldering is shit, i'll look at this picture and feel better about myself:

Interesting enough, this is a 12mhz crystal board, but the red dip switches don't say "cps-dash" to me. Likely this is just parted together like we thought:

BA0C025D-9E85-4A8B-B3E4-0928D8D926D9.jpeg

The board has a lot of gunk around the CPS-A-01 and CPS-B-01 chips. I tried my best to clean it up after these pics:

As expected this is a B-21 based romhack.

So all that being said, the board does work fine. I played though the entire game without issue. The volume pot is really off, it's almost like it has 3 settings, off-whisper-fuckingloud. lol.

I don't mind the hackery, worst case is that I have some spare parts. As it stands I have 3 of 4 CPS1 boards with issues. I love the platform and game library, but the hardware is really unreliable.

@duffcon yup that's same weird audio bodge job we've been seeing.... mine failed, but yours may stay alive longer. The issue I have, is that I can not for the life of me figure out what they're doing. There are diodes where capacitors should be, the weird powering of the knock off Yamaha chips, etc. So not had any luck fixing it.

Mine does not have that audio hack. Not from legendhk anyway.

Test all the DIP switches. Every A board I've received with those red switches on them have had at least 1 that doesn't work correctly.
