How is the 10/12MHz clock situation handled?

I think they are all pretty much garbage, but koryu is my favourite of the lot

The reverse engineering effort is being put more towards FPGA recreation than hardware recreation. Keep an eye on https://www.patreon.com/topapate , he did the CPS1 Mister core, and is currently working on Q-Sound as a stepping stone towards CPS1.5 and CPS2.

Definitely could do with region/condition/revision detail spaces, and for stuff like neo geo, whether it contains box (with or without matching serials),dips,flyers etc... This is just fairly basic stuff that collectors need to know when cataloging their collection, let alone selling amongst...

Do you only want a no-solder mod? There are solder points for line-level audio so that you don't have to take the S-connector and then put a circuit after it... Taito f3 stereo pinout issue

Fantastic writeup, wish I had it back when I had a couple of A-boards that seemed completely functional except for sound (no audio, and volume controls "non-functional" [switches were fine]). I replaced a ton of parts but never worked it out, wonder if this would have helped :)

I had object ram errors on one b-board, turned out to be a single trace below the program rom chips (3-10) leading to the LS245 chips, which connect through to the A-board. See if anything around there is damaged/faulty.

I couldn't find where in patreon the discord link is. There is a 'connect to discord' button under 'membership', but it sets up the role rather than linking to the discord, as far as I can tell. Or do you mean you have to ask Jotego directly for the link, and also be a patron?

Can you provide an invite link to this fabled discord? I can't find any info on it at all, including in patreon member-only posts. I tweeted jotego and he didn't respond. Or is the discord not intended to be open?

As ekorz said, it's an easy romswap from the base Jackie Chan Kung Fu Master game, and well worth the upgrade. FoF is a very fun game, but definitely try it out via emulation first to see if you think it's worth the cost... pick it up if you ever find either board cheaply though!

You've actually got remarkably little trace corrosion around that chip, all my acid deaths have been putting patch wires from that area around the board (mainly to the graphic rom sockets). Likely fixable indeed! I have a spreadsheet with lists of where each pin connects if you need it.

Nice! (whispers: atomiswave)

You should be able to run the board without the daughterboard, will just be missing parts of the graphics, but should be sufficient to allow for poking at other chips which would be covered by it.

Since this seems to be the off-topic thread now... "But where are the drop-bears?"
