Of course, Dial Up is supported in all games and I did not plan to buy BBA, but my friend found Atomiswave Communication Cart for $ 15 and I could not pass by such a laugh price
A little later, I will introduce you to my modification and share the scheme, the whole charm of this mod is that the modem and BBA are one device and you do not need to change them.

This is just genius !!!!!!! Switching them out has always been kinda of a pain, this will make life 100x easier. I bet you even have some sort of switch to changed between the two??? Bravo. This is one of those ideas that just makes sense.

everything is much simpler, there are no switches, the modem and BBA use different buses with common contacts, but the activation signals of each of the devices are individual.
Games that support both the modem and the BBA first of all check for the presence of the BBA and if it is present on the bus, the game will use it despite the fact that the modem is also connected.

I propose we call this the "MV Dual Online Adapter™".

MV for megavolt.

Here's the build tutorial.

This is just awesome, really great project although I’ve not played online since a while..

I see those Atomiswave Communication cartridges all the time on Ebay or Ali Express.

Excited to see what you do with this!
