And it is done. I am not super happy with this mod. Needed a lot of cutting of the shell. The screen has very good quality though!
Would be nice if they sold aftermarket shells exactly for this mod. Screen is also a lot bigger than the original one!

That are quite a few controllers I took care of during the last week. 🪥

Personal favorite is the Sega Saturn controller which is new to my collection. 🎮

This version was sold in the US and EU only as Sega expected players from this region to have bigger hands and therefore would feel much more comfortable with this bulkier version of the controller. Later they also changed the controller for these regions to the original smaller ones from Japan. 🇯🇵

Pausing the project here for a bit. With seven pins dedicated to reading a #SEGA controller, I can use the 8th pin as a signal from the #Arduino not just to indicate when a certain thing is happening, but also as a trigger in #PulseView to start capturing data.

Are you an Arduino/generally a microcontroller or electronics hobbyist? You should go buy a #nanoDLA logic analyser - for a few bucks you can easily visualise exactly what's going on with your I/O signals. Solid recommendation from me.

Its first project will actually not be anything to do with RS-232 - early #SEGA controllers also used a 9-pin D-sub connector, so this same thing can be used to tap those pads' signals as well.

My goal here is not to re-invent the wheel, but to reproduce Jon Thysell's excellent work in deconstructing the SEGA 3- and 6-button controllers' protocols for my own learning and understanding: jonthysell.com/2014/07/26/read

This isn't the SEGA tower of power, it's the... subterranean tunnel of terror?

If the player inserts almost any other Mega Drive cartridge into the slot adapter, again a screen with Sonic characters and a scrolling text "No Way" appears. ✋

This time after pressing the A, B and C button at the same time the player gets to play only a single Special Stage without the password ability based on the serial number of the cartridge's ROM header data. 🔢

If you attach Sonic 2 to the Sonic & Knuckles lock-on this unlocks "Knuckles the Echidna in Sonic the Hedgehog 2", wherein the player can play the game using Knuckles and his abilities. ⬇️

Using these special moves, Knuckles can explore areas inaccessible with Sonic or Tails, where secrets such as extra monitors have been added. ➕
