Should be ready to start rolling them out properly in a few weeks, it's only a matter of time and they will be here
Exciting! Looking forward to receiving it.

You are already in the list
I'll try to dedicate some time this weekend for testing / finishing up peek a boo.
January has been an real scramble for time but hopefully starts to free up soon.
As for the main batch, think we are not long away at all, be ready
First this, then CPS1…it’s going to be an amazing first quarter of 2022!

I need a donor board for this glorious multi. Looking forward to playing these games!
@Hammy were the sprite issues on the multi that @AlxUnderBase, I and others? were having ever sorted out?
I totally lost steam trying to diagnose it between my two Jaleco boards and just checking if it was ever fixed, or can it be assumed that some donor boards are more suitable than others?

I might have a donor, or complete multi up for grabs. I’ll PM you.

I'll test peek a boo tonight , the rat nest test setup was too close to a running 64street to give up on 
Peek a boo is for the standard mms1 setup (overclocked or not, don't matter)
As for the card will be a little add on that sits on the main processor:
It will hold the extra logic and buffering for the sprite stuff
And extra 4 games program - 64 st , chimera , cybattler , big striker (peekaboo replaces big striker @ no 16)
Allow switch between 6 + 10 mhz
Interfaces also to normal mms1 board via another cable so everything is in sync.
As the processor needs to be removed it will be an optional extra for any who have already overclocked and have big striker running already.

There's a known giltch on some motherboards with legend of makai, i am still working on it but testing is remote...
Until one of these 'glitchy' motherboards is on my test bench it's hard to fix the problem.
I have ported peekaboo now so whatever setup you have (overclocked, glitchy motherboard or whatever) you should have at least 16 games that work

Seems like a neat thing. Someday when it's all button'ed up and ready to rock, I'd be in for one!
My body and donor pcb are ready! EPROMS are burnt too, I’m good to go as soon as this drops!
My offer still stands for making pixel icons for this if anyone wants to build a game selector with a display screen. I can get some started by the end of the month (got some other art stuffs to do before then).

The MMS1 hardware is good, it's only a case of any software issues / updates.
Legend of makai is ported from an older PCB don't forget so is considered a bonus
Much like peekaboo (tested and runs! needs prom stuff)
I also noticed that i had not patched the colors for player 2's screen.... there's still a little green tinge to it...

Here's the peek a boo video, it's running well but there's a layering issue missing text and blocks.
Need to mess around with the PROM for this one i think...
This is at 10mhz, the countdown timer goes a bit nuts... (or there's a broken JK again!!...)
