What's new

ZN1 Bios <V2> board arrives!

I've just remember I bought a Gallop Racer 2 board ... in 2021 for this upcoming multi.
I just reread the entire thread and I see I might have missed the offers for the bios board and rom boards.
Should I continue to wait for a more "mature" version in the future or should I bug Hammy now?! :D
I'm a patient guy and can probably wait another 5 years!
 
The bios board will always be useful / never go out of date (once it's fitted)

However the bios board may get easier to install with less wires (as it has done before...) Once fitted, it does not matter what bios board revision it is, the job it does is the same.

If desoldering a chip and adding 9 wires is too much work for you, then best to wait. ... if you are OK with the install and want to start messing around now, it's well reccomended,
 
Desoldering a chip and adding 9 wires sounds like a walk in the park but I'll give you guys time to check the plds and see if things change or not.
Like I said, I'm a patient guy!
Great work btw!
 
Also figured out is memory card / PS1 controller hookups, but it's not tested
(some ZN games test for memory card... it's unknown what happens when one is detected, maybe loading / saving / unlocked stuff?)


Probably PS1 software won't need adjusting if using the controller port... (controlling on the jamma is another story....)
:D
 
Finally, the CONFIG JUMPERS!

Time to get upgrading!!
