Mine is more simple without handbrake or similar.
To change the audio board I have both needed plugs for power and the audio cables.
For FFB I use the MultiFFB from Tibal with a button close to board (for easy FFB rom change).
This works perfectly fine for me and makes it easy to swap games.
I would have the HOTD2 topper from the Deluxe but has some damage (missing a corner) and I do not own a scanner.
If it helps I can do some pictures (with mobile phone).
If I remember correctly the DSB1 and the DSB2 boards use different plugs for power but with same pinout. May need to build an adapter there.
I am doing the same on a Scud Race twin to play various Model 3 racers (bought it from a friend like that). Can do some pictures later of what was done if...
Audio board also has different roms on it.
If you plan to switch the games sometimes I can recommend you the MultiFFB from Tibal so you won't have to change the rom on the drive board.
6 Player Daytona 2 is really nice! Don't forget that the game also offers a live monitor.
I had the opposite issue as I wanted to go for PE. Mainly because of the extra track made of a combination of the other 3. But the round track is so much nicer on BOTE.
Need to check how many BOTE and...
For the Wipi Netbooter you need a Raspberry Pi 3 or 4. Display is optional as you can access it via Wifi from phone or PC. The Raspi will be connected with an RJ45 (network) cable to NetDimm.
I would recommend you the Wipi Netbootber instead. Doesn't need a display for Raspberry Pi as you can use a website through phone or PC.

Bought 2 MultiFFB from @Tibal. Good communication, save package and delivery as promised.
Tested his MultiFFB board with one game so far and couldn't be happier about it. Thanks a lot @Tibal :)
Do you have some details on the MultiFFB?
If I understand correctly it would also work with normal Model 3 stacks.
Could be more than 3 different games be used on one eprom and how should it be burnt?
Do you have 2 on stock? :)
Sorry for late return. Wasn't able to drive to my room earlier. Hope these pictures will help at least. Please let me know when copied, put it temporary on my space to make it easy for download.
